1st Build Power Supply Question

Q: 1st Build Power Supply Question

Hi, Guys (And Gals) I'm attempting my 1st PC build and HAVE used the various online power supply calculators... however I'd like to hear some feedback from you all. No matter where I look online I always like to come here to be sure. My specs for the build are as follows:

Amd A6 5400K 3600Mhz Blk Edt 1mb 65w Socket FM2


HDD: Seagate 1TB Serial ATA HD 7200/64MB/SATA-6G

I would really like to use one of the 350W or 400W power supply I stripped from my previous PC's. I'm thinking of hooking it to an HDMI or VGA projector eventually though (Haven't bought it yet) Can I get away with one of these and play a game like World of Warcraft? or do I need to order something like the
SolidGear 650W PS2 ATX Power Supply on Tiger Direct?

Thanks in advance for any advice & thoughts

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.

The Corsair line of power supplies is excellent. If you are not comfortable with the 650 try the 750; what do you need from the 12v in amps/wattage for Crossfire? Will you be overclocking?

By the way, love the cpu and 4850's in Crossfire and those WD Blacks have a good reputation. Is your system minus the psu ready to be assembled?

I currently have this (and don't want them to collect any dust:
Asus Motherboard

Plus a couple hard drives, but absolutely nothing else. Since this is new to me, I'm asking:

1 - Is there a way the more experienced users would suggest going about a new case and how to know the appropriate power supply to buy.

2 - I bought the MB used from, and it didn't come with any wires/connectors. Can you tell me what I'd need to fully be ready when I have all the components?


A:New build case & power supply recommendations

I havnt done this in a while but here it goes.....

If you dont have the propor heatsink/fan combo you will need one of those for your processor.

For your needs just get a quality 500w PSU by Antec, Silverstone, Thermaltake ect ect. No $20 bargain buys. If you plan on putting in some super fancy graphics card, take the minumum requirments for that card off the box and add 100 watts.

Wires you will need are just your SATA cables.

The PSU should come with all you need to connect it to your motherboard.

A:Power Supply Question & HD Power Consumption

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.

I just got a new 500 watt power supply. The old one was overheating. The new one has a switch for a normal fan or turbo fan. The temperature runs around 48 C most of the time but has spikes up to 70 C (I have a temperature monitor software). When I put it on Turbo the system stays nice and cool all of the time. Is it going to hurt anything to leave it on Turbo all of the time? Thanks,

A:Power Supply Question

It will hurt nothing but your power bill (how ironic), and your ego if you are competing with someone for the quietest machine.

Of course, it may decrease the time before the fan bearings wear out, but I don't think that's a big concern at all.

With the cost of electricity nowdays, I was wondering about power supply electrical consumption:
Does a typical power supply draw the exact amount of current it is rated at on a consistent basis or does it adjust itself to only use as much AC current as the computer is using at whatever time?
For example, say I have a computer that draws 150 watts of power for its use but it had a power supply that is rated at 450 watts. Would the electrical usage of this computer be 450watts, 150 watts or some other amount?

A:Power Supply Question

The power supply's energy consumption is directly related to the amount of hardware that's attached to it, therefore a 450W PS might draw a little more power than a 300W PS, but not necessarily depending on the PC's power requirements from the CPU and drives.

As per your example, I would expect the 450w supply to draw approximately just a little more than 150w.

The rating put on the supply is the max wattage drawn before the supply becomes overheated or unstable.

As far as I`m aware, Sony use generic psu`s. However, it might be a good idea to check with sony, just to make sure.

As for the psu you`re thinking of buying, don`t. It only has an output of 18amps on the 12volt rail.

Any suggetions on the what amps are needed on the different rails for best, most stable results? Any help would be great. Here are my system specs (no overclocking):

A:Power Supply Question

the amount of current on the +12V rail needed will depend on the PSU. on a cheap PSU, they "play" with the numbers to make the amperage and overall power rating seem much higher than it truely is. (they basically rate the wattage at an ambient system temp much lower than the average system really is) They also have more current on the 3V and 5V rails (which newer systems no longer need).

for now you should strip your system down to bare bones. Run it with just the CPU, 1 stick of RAM, onboard sound, and the boot hard drive (make sure that power cables are disconnected to all other unused components)

boot up and try to make the system reboot, if it doesn't... then add 1 component at a time until you find your problem

Does anyone here know if the talk I've been hearing about GF4 Ti's needing a minimum of 300 watt's with the power supply is fact or if it is some peoples idea of problems with compatability on certain systems? I went to the Dell and Gateway websites and they offer the 4600 in their systems that are powered by 250 watt supplys. I was hoping to find some facts on this. Also no reviews ever mentioned it.

A:GF4 Ti & Power Supply question

Everyone gets pretty confused about this. No, the card in itself does not require 300w, but will draw apx. 50w & up to 75w under load (extreme gaming) However, adding another 50w draw may tax your system, necessitating a 300w psu, or better.

I have a question about the +12 rating on a PSU. I have a 14A rating. Is a higher or lower number better. Reason is, I'm looking to upgrade my video card, but don't want to change the PSU too.

A:Power Supply Question

The higher the number the better. Does your PSU by chance have two 12v rails? If so, you can add the two together (but not the -12v rail).

It'll all depend on what you have, and what you are trying to put in. If you are wanting to put in a newer graphics card, you'll want to be up in the 24A range total on your 12v rail(s).

Good day,
My power supply is making a strange noise on startup and after about 1 minute it settles, is there anything I can do about it besides replacing it?
The mother board connection is 24 pins and the power supply connection in the PC at present has a 20 pin + a 4 pin connector I do have a spare ATX power suply but it only has the 20 pin connector without the extra 4 pin connector, can I use that power supply in my PC?
Many thanks,

A:atx power supply question

1st of all define "strange noise". You need to post the EXACT make and model of the problematic power supply and the EXACT make and model of the spare power supply you have that you intend to use.

If your machine has a PCIe graphics card installed you cannot use the power supply with the 20 pin main connector. The +4 pin connector on the power supply with the 20+4 (pins 11, 12, 23 and 24) supply 75 watts of power to the PCIe bus.

Nope. If your motherboard has a 24pin connector, and your PSU only has 20pins, it's not a good combo. Return the PSU before your computer suffers irreversible damage, and get the proper type of PSU.

I have a IN WIN BT611 case which has a 300 w power supply and dual 12 v rails. Do you think my system will be ok to run with the above following power supply ?
Its just that powersupply for these cases are hard to get hold off as they are quite bespoke,

Also, what do you think of the above combo for a new budget system ?

A:power supply question

In Win is not in any means a reputable power supply manufacturer. If you're sure you want to use that exact case, then I'd recommend this power supply:

Something like a Gigabyte 740G or 785G ATX board with an Athlon 62X2 5050e or 4850e would be my choice for a low-power system.. Especially the 785G has great upgrade potential and stability compared to an GeForce 7100 chipset board...

I would think you are installing this card for gaming. Gaming and cheap/inexpensive are mutually exclusive terms. If you are going to game with this system, you need a quality pw supply. Here is an example of what you need;

You do need to understand that acer uses low end ie junk parts in their systems and even with a gtx650, you might not be satisfied with the performance of the system.

A:Power Supply Question

When it goes kaput, its failing circuits are capable of failing voltage regulations in all directions and can subsequently fry about anything in the system, including the board.

Frankly, I think cheap power supplies are responsible for more main board deaths than any other single cause; but, that is just my opinion.

My feeling is that you can't trust any power supply in the sub-fifty-dollar range and maybe it would be better to stick to $60 and up. It seems a lot of my main board problems started going away when I started buying Antec supplies in the $60+ range. Mine are all in the 400- to 480-watt range. I might not need quite that much wattage; but, buying lower wattages doesn't save enough to worry over. Also, the higher the wattage of a quality power supply, the less the strain and the longer the life.

So i was reading a review on a chassis/case i recently bought...and they said that the psu sucks (i kno, most power supplys that come with case's usually arnt top notch) but then he went into the +12V being a ive always known about these numbers but never knew WHAT it meant..anyone want to explain? lol

A:Power Supply Question

A=amperage, power(watts)=volts x amps(current)

The 12 volt rail(s) run the video card, CPU, drives, and fans. Often the video card specs say about the amps on the 12 volt rail you need. It's much better to look at the rail specs of a PSU because some PSUs will have most of the power on the 5 volt rail and be rated high power like 400-500 watts. For a basic system 18a on the 12 volt rail should do, but for a gaming system with a single high end video card you want about 30 amps. With dual video cards you need to spend some dollars!

You want to know if you can use a standard ATX power supply in your case? First we need to know what case you have. If you don't know, then you could also take a look at the PSU you have in there now and see what size it is. It will tell you on the sticker attached to it.

Recently my power supply got damaged due to a thunderstorm even tough I had a
good surge protector installed.

Obviously the best protection would be to disconnect the computer from the plug.

But I wonder if just switching the surge protector off would provide the same security ?
Or could a lightning still cause damages ?


A:Power Supply Question

Although highly unlikely, it's still possible that a really bad direct strike would still find it's way down the path in to your PC.

As long is there is an unbroken chain of wire from the house electric system to your PC, there is a chance (albeit an extremely small one) that you could still suffer some damage.

IMO - is this likely to ever happen? No. Don't worry about it.

A:Hp power supply question

The easiest and quickest way to test the power supply is to take the tower to a shop where they have a power supply tester.

They can test the power supply and if the power supply is defective they also can "jump" a known good power supply to the motherboard to make sure that when the power supply failed it didn't take out the motherboard.

I do these tests quite often in my shop, takes about 30 minutes total time and the cost should be minimal perhaps $25-$30.

First of all STOP cycling the power on and off. You will make a bad situation much worse. Next replace the ps. Cold boot problems that go away after the first failed boot are almost always ps problems. Do not buy a cheap ps like powmax, deer, allied, foxconn, raidmax or any other cheap brand. Go with a quality unit like antec, enermax, coolmax, enlight, or sparkle. There are other good brands, however those are what I use in my builds.

The SATA is used for connecting your drives. Your power supply for all I know doesn't need those type of connections.

A:Power supply question

I think so mate it looks like a lot of hardware in there to be powering. I mean each component probably is not drawing much but you do have a lot of hard drives and fans etc etc and 8 gb of ram. I think it would not hurt to have a bit more juice to run your parts.

just a quick question my hardware is -
intel i7 860 @3.7ghz
gtx 480
6gb ram
dhh55 mobo
and a hard drive and a dvd-rw driver
would a 650m watt corsair psu do for that system?

A:power supply question

Is this a new power supply?
If yes, then the power supply should work ok

Trying to diagnose a computer problem.

The computer does not boot up. It starts, and all fans are spinning, and the HD ( I tried 2 hard drives actually) seems to be spinning.

I am wondering if the PS is failing?

If the PS is done, will you get ANY power at all, or will you press the on button, and get no juice?

Also, there is no burning or "heat" smell coming from the PS.

If it is not the PS, my next guess is the MOBO, but I am not really sure how to test if a MOBO is pooched.

Thanks in advance.

Hi, im about to start buying a new mobo and possibly another video card, and was wondering if my current PSU, a SilverStone Zeus ST56ZF 560W, can handle the HDDs listed in my system specs, the processor listed, the video card currently listed, and the new mobo? Right now, that's my main concern, but i am also curious to know if that PSU might be able to handle that new load with two GeForcr 9800GT cards SLI'd together?

the mobo:

Also, i really appreciate the help, so thanks!

This afternoon I started hearing a noise from a fan. Not real loud but it was just louder than usual. I took the cover off and it is the Power Supply fan that is making the noise. Everything still works OK, but just curious if this has happened to any of you and if you think this might be the Power Supply on the way out. Thanks,

Mine started ding that after a few months. I decided to get an RMA on it but never bothered and it's still running fine.

I have been looking at different power supplies but don't know what to get.
I have noticed that many have sinle rail, some dual and some have quad. Does this really make that much difference ? What would you suggest ? This going into a new computer so I can upgrade the video card. Probably 600w or more.
Thank you for your help.

I have an old Dell 0M3918 Motherboard that has the original power supply. I'm looking to upgrade that power supply so that I can have more power, and most of the power supplies I've seen are 20 pin connectors. The board uses a 24 pin connector. Are these new PSUs compatible with my board? I can see they have a 4 pin connector that's 2x2, and my assumption is that you use that as well, but my PSU has one of those anyway and its currently plugged in at a different spot on the motherboard, well away from the main 24 pin connector.

A:Power supply question

All the 24-pin power supplies I've seen have a detachable four-pin part to make it compatible with the 20-pin boards. (The wiring is the same on the first 20 pins.) It usually is not visible in the product pictures; but, it is there. I have seen some detail pictures of supplies at where you can see the demarkation point between the 20-pin part and the extra four pins. That's where it breaks.

As for the extra four-pin connection, that is separate entirely from the twenty-four pin part.

You can see fairly detailed pictures at NewEgg.

I did a check to see how much power my computer needed and apparently it needs 38w. Is this right? It has a max output of 230volts and i am looking to get a new video card, i know i will need a new psu you to sufficiently power it, i might get a 400. Would this be enough? Thanks

A:Power Supply Question, 38w?

Where di you see the 36w at?
For a typical desktop, you're probably looking around 300-400w, but then again, if you tell us the computer specs, you could get an answer with better accuracy

iv recently had some bad computer luck. what happened is that my computer would shut off at random for no reason and the light on the front would blink untill i unplugged the power supply then it would stop id try again and the same problem would happen. now it doesnt even start it freezes while loading i think its because it doesnt have enough power to run the devices in my computer. does anyone know if this is my power supplies fault

A:Power supply question

blinking could mean a few things including your computer shut down due to serious overheat, under powered, cpu failure, ...
is there dust inside your computer?
is there dust on the fans of your computer?
when you turn your computer on can you go into your bios and find an area that gives your temperatures, fan speed, voltage??????

I'm building a Gaming rig for as cheap as possible.
150$ cpu - video card - 50$ mobo . I checked the Newegg power supply chart and it says I should get 450w.

I can get a 80 certified 500w PSU for 40$ or a 600w non 80-cert psu for 30$. - Diablotek DA Series PSDA600 600W ATX12V v2.2 Power Supply 30$ - COOLMAX ZX Series ZX-500 500W ATX12V v2.2 / EPS12V v2.91 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply 40$

If my system really only pulls 450w, would the 500w work?
more importantly, even if the 600w only runs at 75 percent, it should work also right?

I dont have 50 bucks to blow on a PSU. Hardly 40.

Anyone know of a great PSU for cheap?

Hello everyone ...

Although I am a huge PC enthusiast, I am building a different sort of machine that makes use of a typical PC Power Supply.

OK, I'll just admit it ... I'm making a food dehydrator ... and I need to rig some fans to facilitate airflow / convection.

Here's my idea: Use a powersupply, connected to several PC fans, to drive that airflow through the dehydrator itself.

My question: The main 20 pins connector (coming from the Power Supply) needs to have a jumper on some pins .... right? Which ones? How do I rig this puppy so it's stand-alone and powers the fans only?


A:Power Supply question

They are all posted on good power supply manufacturer sites... and in such books as Building and Repairing PC's.

The problem is that food properly handled in a dehydrator requires better, and more consistent airflow, and temperature controls, than any power supply I have seen can handle... leading to spoilage. You are likely to have quality control problems... no to mention insects.

Hi guys, i just ordered a power supply and it came in with the P1 connector having only 19 wire /pin. It is missing 1 pin/wire. Is it suppose to be like that? Can I still use the power supply?

Should a powmax 400W PSU be able to handle an AMD sempron 2600+ with a cdrom, harddrive 3 led fans and a 6600GT. Cuz my system won't even power up anymore. And I've had this thing since roughly mid-march.

A:Power supply question

Kagami. Powmax are known to be crappy PSU's. It most likely crapped out on you.
