Corsair Power Supply Questionable

Q: Corsair Power Supply Questionable

I was given a year old Corsair power supply XMPSU- TX-C I wanted to make sure it Questionable Power Corsair Supply s working right before plugging it to a motherboard So I did the paper clip power on trick and all the voltages were ok I proceeded to connect just one harddrive The harddrive spins up and then Corsair Power Supply Questionable makes a revving noise every second as if its powering down and back up repeatedly Also theres a green LED light on the harddrive that blinks normally its a solid on This doesn t happen every time I cycle the power supply however When the harddrive powers up properly the LED light is constantly on and rpm is constant I tried two other harddrive with the same outcome The problem is definitely intermittent I connected all three harddrives with the same results I tried the same setup with two other power supplies with no issues at all I am now sure the issue is specific with the Corsair power supply Is it because there s not enough load on all rails making the power supply unstable The AC current draw was only mA so it wasn t the overcurrent protection kicking in The V line was steady Corsair Power Supply Questionable but the V line fluctuated a few hundredths of a volt in unison Corsair Power Supply Questionable with the harddrive revving The V line was steady when the harddrive powers up normally I m hesitant to connect a full computer to this Anyone have an idea before I try to RMA the power supply Is this just a peculiarity of this model nbsp

Hey Folks! I'm planning on swapping out my Dell Dimension 3000's current power supply with a new one and I'm checking out the supplies on Best Buy's website. Can anybody recommend me a power supply that's got high wattage but nothing considered overkill? I mainly listen to music, download films (legal downloads) and watch ripped DVDs on the HDD so I'm not looking for something that'll power a small third world country. I'm no gamer so I'm just interested in a power supply that'll give me great power and last me a few years without breaking the bank.

Here's a list of power supplies I'm looking at:

Corsair is generally considered to be a slightly more reliable brand. I personally would suggest a single 12V rail with high amperage. Do you require a modular PSU? If not, then the Corsair 650TX is cheaper than it's modular counterpart, the 650HX.

I think that for a single PowerColor HD 4850 the Corsair 550VX will be more than sufficient. However, if you're looking to keep the system more "forward compatible" (not future proof because nothing is), the Corsair 650TX should do great. I would think that the 650TX would be the best choice for CrossFire with 2 HD 4850s.

I have put together a new build with the Gigabyte Assassin 2 m/board and a Corsair AX 860i PSU. On start up the PSU clicks out and won't run. The PSU Self test is good - green light and the fan is running, however when I connect all the peripherals the PSU just drops out and will not run. I have double checked all connections from the CPU, M/board, memory, graphics cards. This is all in a Thermaltake Level 10 case, my next check will be the hard drive connections - hot swap bays. Any help will be really appreciated.

A:Corsair PSU upgrade does not post, powers up 5 seconds power...

I have an addendum to add to this thread.  To refresh, my questions focused on a possible mis-match of PSU and motherboard specs:  Is it an ATX 12 Volt 2.0 and above spec problem or a Wattage cap problem?  I posted my questions to the Corsair PSU Forum concurrently and I paste here now, a response to RAM GUY.   "Hi RAM GUY,Sorry I could not reply until now.  Thank you for clarifying the difference between the ATX 2.0 spec and 2.01spec in that the Negative -5 Volt Rail is not present in the 2.01 spec andbeyond.  As I mentioned previously, the Thermaltake PSU that has beenrunning in my 2009, HP i7 Tower for the last 7 months says 12 Volt ATX 2.2on the case and even though the OEM HP power supply says 12 Volt ATX2.0 in spec literature I found on Google, the actual PSU I have does nothave any ATX spec rating on the case.  So I think it is safe to say, mymotherboard does not require the Negative -5 Volt Rail in that it playednicely with 12 Volt ATX 2.2 spec up until recently.Though theoretically there is supposed to be no limit on the amount ofWattage you can use to power your motherboard because the motherboardis suppose to use only what it needs and cap the rest, it appears that OEMscan dial up Wattage limitations if they deem necessary.  Could be as simple HP, not wanting to compete with some of it's HPsProfessional Work Stations, thereby caps Wattage on some Pavilion EliteSeries models to prevent them from becoming a much less expensivesolution.In any case, I think with all available information digested, it's not aboutATX specs, but rather my HP motherboard has a Wattage limit of 650 Wattsthough I think I read someone else got the same motherboard going with750 Watts but I don't remember where to find that posting."I am back up and running, yeah !Thank you again Lasvegaswireman !

Toshiba Satellite L305-5955, Ive taken apart and replaced power jack. Not directly soldered to motherboard. While still apart, and battery out/in, connected power supply and still absolutely no response. Power supply is NOT original, and slightly different specs, i.e original 19v..6.3A

current 19v..3.1A

A:Toshiba Satellite L305-5955 does not respond to power supply, new power jack

Almost certainly the problem is that the current rating is wrong, if the laptop needs
6.3 A of current, it won't function on less (just as you can't use a 3A fuse for a kettle!)
Unfortunately it must be the right current rating, I know, I've been caught that way too!
Maybe you can exchange it?

I picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.

A:No power, no lights but green light on power supply blinks rapidly

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

I have a Dell 8600 about two years old. When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so. I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally. Any ideas?

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

Hello guys.  Can anyone help me understand the power supply on the HP Envy Phoenix 860-019?  The PCIE connector 6 pin connected to the GTX 960 has black and white wires.  Shouldn't there be yellow and black wires?  Yellow is usually 12 volt and black wires ground.  Is the 6 pin connected to my GTX 960  supplying a standard 75 watts of power or something else?  I want to install a GTX 1070 but the 6 pin wire colors are not the industry standard color scheme.  Also there is a 2 pin power connector with a white and black wire.  Usually a 6 pin and a 2 pin can be used together to connect into a 8 pin socket on a GTX 1070.  Will my connectors supply the needed power and connect properly because the color scheme on the wires make no sense. Thank you

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place. My warranty with best buy has expired, so I need to figure out how to solve this problem on my own. I can't just leave it like this because the cord comes out really easily and I can't continue to work with such a tenuous setup. Anyway, is this just a matter of replacing the entire unit inside my laptop? I know you probably need more information, but I'm not sure what to provide, so please ask any questions. The laptop is a Toshia M-45, about 3-4 years old. Thanks in advance

gfx: Sapphire HD3850 512MB Ultimate (passive)

MB: MSI P35 Neo2 FIR

PSU: Seasonic M12II 500W

The motherboard has a power connector for the graphic card next to the slot.

Is there any reason I should connect the power for the card to the power connector on the board instead of directly to the power supply?

A:Graphic card power to power supply or connector on motherboard?

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

As you did not mention any message or display on the screen, I would use this tutorial for a step by step diagnostic.  It also helps to remove the side panel, and visually watch the CPU and rear case fan movement(s).  As you press the power button, pay attention to the fans. Also does the Power Supply LED stay ON? Or did it go OUT when you pressed the power button?

Then you can press the power button and turn it back on.

Power Supply Question & HD Power Consumption, Pt. 2 - Laptop vs. 3.5"

My second question is this - I have a BTV server that needs to be on at all times during the season to record shows during day and evening.

Suffice it to say that you CANNOT reliably put one of the critters into sleep/hibernate mode and expect it to wake up and reliably record a show. It just won't happen.

Now, this is one case where I can use "Green" 3.5" drives, but I am also considering banking 500GB 7200RPM or even 5400RPM laptop drives. These will all be on a raid controller, but since they will be in pass-thru mode or RAID 0 mode the controller won't freak over TLER like it would with RAID 5/6 and mark the drives bad. The controller also has more than adequate cache to handle a 5400RPM spindle as OTA HDTV generates little more than 2.5MB per second per channel. Even 4 channels at once is 10MB/s and that should not tap the ability of a 3Ware controller with cache on 5400 RPM RAID 0 or even pass-thru drives.

My question is this - 2 500GB laptop drives burn much less startup and idle current than a single 1TB 3.5" drive. Has anyone tried running multiple laptop drives on a RAID controller, and what sort of luck have you had? What sort of sustained throuput can you obtain?

Electricity is a huge factor here, at 12 cents per KWh. I can recover the marginal cost of 2 500GB laptop drives vs. 1 1TB 3.5 drive.

Case construction and drive cages are not the issue here.

Finally broke down and started building a new system - I m too old to game this all started out as a home video project Anyway - gathered all my components now I m working to assemble them The case power plug. fan power New for supply, no schematic, looking came with New power supply, no schematic, looking for power fan plug. an Okia Model -ATX power supply But no wiring schematic I m trying to identify the power supply fan plug - what New power supply, no schematic, looking for power fan plug. seems to be it doesn t at all match the connector on the board And I ve got that positively identified by the board manual The board has a small male pin connection The only thing I can find that might be the fan connector coming from the supply is a small pin plug at the end of of the New power supply, no schematic, looking for power fan plug. strings of drive power harnesses Nothing tucked up behind the supply case or anything Is that likely to be it Or would that be for a floppy or something I tried to Google for a wiring schematic but could find nothing In fact nothing much at all on this brand of supply - just a couple places that sell them Please don t tell me I got an el cheapo that isn t worth having At the risk of getting ahead of myself in case I need to adapt something like that to the different style male connector on the board in this case or something else I may find as i progress is there some type of source for adapters or what would I do Bear with me this probly won t be the last question I ll dream up - just getting started While I m at it - the board manual talks about a connector for a power supply that senses board temps - that s another reason I d like to find a schematic or some sort of instructions for the power supply OH The connectors for the fans in the case don t match the connector on the board either The board has another small male pin connector for the case fan s but these have a larger bigger pin pin connector Again - I suppose it s adapter time Guess I ll need that source Thanks for helping an quot old quot computer student still and probly always in a definite learning curve nbsp

A:New power supply, no schematic, looking for power fan plug.

There are basically two voltages available to you: 5V and 12V. Doesn't really matter where you get it from - some pin on the mobo or some wire from the PSU.

From the PSU the yellow wires are 12V and red ones 5V, black is ground. The fan voltages should be written on the fan itself, the black fan wire is ground, red may be 12V or 5V depending on the fan voltage.

Fan headers on the motherboard should be labelled so, check with a voltmeter what pin gives out what.

Ok so lately I have been getting a BSOD at very random times and it looks like a Diver Power State failure. SO all of my friends and every website I go to makes it seem like I need to get a PSU. Right now I have a Quad Core and a 8800GT and 375W PSU. So my friend told me to get a new 700W PSU.

So, if the only fix is to get a new PSU? I tried to rollback my GPU driver but it didn't help.

So any ideas?

A:Driver Power Failure = New Power Supply?

You're greatly risking the health of your whole computer while running with such underpowered power supply. Do yourself a favour and get a quality PSU. That's the cheapest one that is enough and of good quality that I could find with a quickish search.

Hello everyone - I have just assembled a new build It will not power up I need a suggestion to figure out if the problem is the case or the motherboard This is a mini-itx build power-up: power New or Build MB? no supply case's The case is New Build no power-up: case's power supply or MB? Linkworld LC - B This case comes with a volt watt external laptop-style power supply that plugs into the rear of the case just like New Build no power-up: case's power supply or MB? a laptop power supply plugs into a laptop - a barrel connector Inside this power connection connects to a power supply component that is not like a regular ATX power supply but is on a printed-circuit board New Build no power-up: case's power supply or MB? mounted on the case This has several capacitors and other stuff From that comes the -pin and -pin power supply lines for the motherboard I assume the -volt power supply for this external power supply unit is right since it came with the case It was watt The processor is an IBM t with TDP of watts Lower-powered CPUs can be put in a small so I assumed the power supply might be under-powered I ordered a -watt volt power supply with the right size barrel - and same polarity pos inside The MB is an ASRock H MV-ITX It is mini-itx form factor Still same problem Everything is connected correctly When I press the power-on button an external CD drive I have plugged-in spins up for a while But no power light comes on in the front of the case there are no POST beeps the fan for the CPU does not spin up No other signs of life So power is getting into the MB - the external CD drive is plugged into a USB socket in the rear panel of the MB After trying a watt and watt power supply I believe the problem cannot be the power supply cord Can it be that I have too little load I don t think so I plugged in another mm fan and an ol-fashion floppy drive just the power connection to add more load - same thing no power-up no POST nothing but the CD drive will spin up when I open-then-close it yet again So here is the help I need what else can I try -assuming the MB and case are fine is it more likely the case power supply is bad or the MB --Thanks nbsp

A:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

Hey, got quite a problem with my laptop.. It's a Medion Erazer X7813, worked well for ~2 years.
I was doing a graphics card benchmark yesterday and it stopped in the middle of it(monitored temperature, it was at ~80 degrees Celsius when it turned off). No bluescreen or anything just off and I couldnt restart after that(no fans nothing). I thought it might be the power supply, so I tested it, but it was doing 19v when not plugged in, but when I plugged it in and unplugged it again it was at 1v. When testing I unintentionally shorted the power supply and it showed 1v after that just as it did after plugging it in, is it shorting inside the laptop? Could it be the battery or something more serious like the MB? Any ideas are welcome!

Hi I m currently a computing student so I rely won't up power (poss. Computer supply) power on my computer a lot for my studies and was hoping I could get some quick advice troubleshooting on here So here goes I ve had a problem with my computer recently it s been working fine Computer won't power up (poss. power supply) for a year or so with no problems and then one day i tried switching it on and nothing happened I tried once more and then the power short circuited I then had to turn the power back on from the mains switch The strange thing is my housemate had exactly the same problem and after searching for the answer he was told it was due to a static buildup and the solution was to take out components graphics card RAM e t c and put them back in I tried this and no luck I was thinking due to the short circuit there may be a problem with a fuse in the power supply other then that I m completely stumped and would appreciate any help given Many Thanks for all help received nbsp

A:Computer won't power up (poss. power supply)

Does it happen with any other appliances? as in does using the toaster while using the kettle While your mate is in the Electric shower, telly on, or ironing?

Possibly a static build up, it is possible, Wher are you situated??
What voltage are you on?

What is the make and model of your comp? is it the same as your friends?

is your machine custom built or is it a brand?
Answer a few of them and we will try to narrow it down 4 you..

Mean while if you could get your hands on a spare PSU that would be handy. And remember when dealing with PSU's alway leave them to sischarge for at least 24hrs,
the 3 D'S, Disconect, discharge, dismantle.

I have a generic MB (P-120 CPU ) which I just switched to a different case and power supply. It has an extra "six pin power type connection" in the middle of the board. Only one supply that I have matchs this and the wires are three green and three black. What is the funtion of this connector, it looks from the wire colors to be some form of switch.

Its a case of not wanting to swap out the power suppy from my other unit unless necessary. I have 4 other supplies and none have the extra wire, which is listed as P10.

Many thanks in advance.

A:extra power leads on power supply?

Sounds like typical extra +5V lead and can be used for any number of things...(riser cards,backplanes,to drive extra slots, etc.)
Without knowing the specs. on your motherboard this question is impossible to answer...Post Mobo identification (make/model) or obtain FCC ID and post that. Perhaps we can find a more definitive answer for you...BOL

I reckon a 500W wouldn't be enough but a 750W may be the right one. I had a look in a few forums and they had 650W & 750W etc but not 500W.

I have a Delta DPS-150GB B Power Supply out of an Apple Macintosh Power Mac computer. I would like to use it as a 12v/5A power supply for my model train layout. I have a couple important questions:

1) I need to know the pin-outs of the connectors (1-4pin, 1-14pin, 1-5pin on ribbon wire), specifically which ones control start-up and various voltage outputs.

2) Being a Switching Power Supply, I think there must be a load on at least one of the output rails. Can I create this with a simple resistor of some sort? if so, how exactly what would I need to do.

I can email photo of the connectors if that would halp. I would appreciate any help. Thanks.

A:Power supply and mobo are 100%, no power

There are some motherboards that have a power on button directly on the motherboard. I don't suppose you have one of those? There are some BIOS' that can enable the keyboard to power on the PC by pressing any key. I'm using one of them now. Of course, the problem with that is to get the PC started in the first place so you can change the BIOS setting (if it has that setting).

What motherboard do you have?

My PC suddenly shut off and wouldn't turn on, but the mouse and motherboard lights were still on. A tech took my PC and ran some tests. I assumed that either my Power supply or my Motherboard was unfunctional but he called me back telling me that it was neither, and that the problem was coming from "a part" that gave power to the motherboard. The replacement of this part would cost $80.

Am I getting ripped off? What part could possibly cost $80 and isn't the Power supply?

A:Power Supply - "The AC power adapter type cannot be determined....."

You are correct, the failure is due toloss of the power supply ID signal. Sometimes this happens because of strain on the plug, which breaks the signal wire. Some even are so severe that the insulation breaks away from the plug; this is due to rough handling. The other cause is one or more of the power socket solder connections to the system board become broken. This also is related to severe handling. I have seen one case where all three power connections and three of four mechanical connections were disconnected. If the power supply is bad, a replacement will cure the problem. If not, then the socket is bad, and this will require a system board replacement. If you are experienced, you can try to resolder the connections. I am experienced and was not able to get my daughter's E6000 to work by resoldered. More recent Dells are using a replacable power connection board which is a much cheaper repair.

My computer was shut off last night about 6:30PM and left off until about 3AM this morning. It worked fine until this morning and it wouldn't turn on at all. Later on in the day I tried it again and the same thing. I checked the power wire on the back of the computer to make sure it wasn't loose, it was fine, I tried different power outlets, that wasn't it, I even tried a completely different power cable, and it still didn't work. The only thing I can think is that the power supply just quit working. Can anything else cause it to just not switch on?

This one is about $50 for a mid-range PSU. For high end $100 -

can a bad power supply burn out a MB?
I put together a new system turned it on and it was dead. I took another system and by interchanging the board with the known good system determined the board was dead and newegg is sending another.
I think that in testing I took the working MB and plugged it into the new case and power supply and I dont remember it not working.
Now I am putting the older system back together and it is dead!
This seems like more than a coincidence. Is it possible the new PS (thermaltake 420w) is shorting out the boards?

I brought a 400watt power supply from eBay

it has the sticker on the side that lists the power but i want to make sure that it can actually give 400watts

because i know that it isn't too hard to change the sticker or change the case and replace the internals with the internals of a 250-300 watt PSU

are there any tools that i can use to check if the power supply can give 400 watts?

it is a PSU made by ultra

i don't have anything in my pc that will cause power usage in the 400 watt range so i will need to get something that can test it (or is there a way to find out what the PSU really is by opening it. (i open my power supplies 3-4 times a year to clean out all of the dust but haven't noticed anything that can tell me the power in plain English)

Hello All,

I just got a new power supply because my other one just died. I bought a new one and installed it and plugged everything back up. Now the problem is every so often my computer restarts for no reason. I have no idea why it does this, did I need to set something up or is my computer overheating?
I downloaded a program that tells me the temperature and my
Case is 102 F
CPU Diode is 92 F
CPU Socket is 84 F

Thanks for the help.

A:New Power Supply


Not knowing your Computer specifics or power requirements it is hard to determine what minimum power supply is right for your system. As far as overheating I do not think that is your problem.
Have a look at this Website for general average heat listings for all processors.

It sounds more like you may have a critical voltage supply dropping out or below minimums during operation that is causing the restart. I know you just purchased that Power Supply but it too could be defective, or a component on the motherboard failed when the last supply failed. Hard to tell at this point. Best to try a known good adequate supply before continuing further.

Hope that helps a bit.

Take care

A:Power Supply or other?

I would first suspect one of your subsystems may be loading down the power supply. If it were my machine, I would open up the case and systematically unplug the power from your peripherals one at a time and then power up after each disconnect. If the power stays on after a disconnect then you probably found the culprit. Eventually, you may have to disconnect power from the motherboard. Once everything is disconnected and the power still won't stay on, then I would suspect the power supply. Be sure to unplug the AC power each time you stick your hands inside the case.

Just a simple question hopefully. I have a Dell Dimension 1100 desktop and I tried putting a 400 watt power supply in it. BUT when I'd turn it on the tower would power up but the power light changed from green to blinking orange. Is it because the motherboard won't support a power supply that size? Also my monitor just stayed black. I got the supply from Ebay so I'm kind of curious if it is a lemon or not. I need the extra power so my video card will run at optimal values.

The power supply on my Dell Inspiron died less than six months after purchase.  The warranty provides for 1-2 business days service BUT the part is back ordered and no one can say when or if it will be supplied.  This is a mission critical computer for a small non-profit that serves children that have been abused.  Dell is worth 25 BILLION dollars.  The warranty, however, appears to be worthless.  We spent nearly $500 in charitable contributions to buy this Inspiron desktop ... and the best we can get for service is "if, maybe, or could be ... but we don't know when".  I would ask all community members to join me in reviewing Dell's warranty services, online, as utterly worthless.  I have purchased many Dell computers over the years for NGO(S) ... this will be the last.  What a disappointment!

No fair laughing at this dumb question!!!!!!!! The air flow from my case fan is quit strong while the power supply fan hardly moves a piece of ribbon. Should the air flow from the power supply fan be as strong as a case fan. Never paid any attention to it before---just happen to notice.
Case temp is 29C and CPU is 47C

A:Power supply fan

Usualy when a power supply fan fails it will start to whirrl , growl,etc..etc.. But since yours doesn't make any sound, might wanna try and replace the fan. Should be either a 80 mm or 92 mm fan.
When it comes to the air flow, as long as you have intake and exhausts fans that move the air inside the case , shouldn't be too much of a problem for the peripherals. The only problem that you might experience will be an overheat of the psu.
Also since you didn't post the make and model of the psu , it's possible that the psu has it own thermal controller. As in "speed up " or "speed down" depeding of the internal temp. So it's possible that since you have ample air flow in the case, the psu doesn't need to "speed up". On the other hand it's possible that the temp sensor failed and it gives fals readings.
In any case, might wanna touch the psu and see how hot it gets ( it's not quite accurate, but at least it's a start).
And if it's a standard psu it should "move" quite a bit more air then a " ribbon".

9800GT which replaced the discountinued 8800GT is what you should look at:

9800GT singe slot:
9800GT Dual slot:

Note: 9800 / 8800 cards generate a lot of heat... You may want to look at a bit cooler running ATI 4850 card... or the slower 4670 card. A dual slot card will help exhaust the heat.

Top level PSUs:
OCZ, FSP, Seasonic, Corsair, PC Power & Cooling, Zalman, SilverStone, Gigabyte

Good PSUs:
Antec, Enermax, Sparkle, Coolermaster. (some of these are TOP end)

Should Avoid:
Aerocool, Apevia, Apex, Athena, Chieftex, coolmax, Dynapower, e-power, Linkworld, Powmax, raidmax. Many of these are exactly the same thing.

I'd say a good quality 750~850watt PSU should handle that.

It is very possible. If your PSU is running borderline with required system power requirements, or even less than requirements, you will see this.
It appears time to upgrade your PSU.
