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

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

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

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

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

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.

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

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.

Okay, helpin a guy on the floor build a new computer, we got the parts down.

AMD 3000 Venice, Gigabyte motherboard, 6600 PCI-e, 1 gig ram, 160 SATA, dvd burner, dvd rom.

Only left is the case and power supply. Lights and windows would be unwanted.
He is always messing with Photoshop CS-2 and so it must be a semi-nice powersupply. He may even try dual monitors. Hence the 6600 (they are also cheap now). Anybody have any experience with cases that come with power supplies and cost at or below $45. 45.76 is the magic number, but the real question is if we should go with seperate power supply, or will the ones that come with a case be fine. people on newegg, either dont mention the power supply, or say the replaced it.

Hey all,
Im just wondering if anyone knows of any ATX tower cases out there, preferably with an aluminium/black finish and front door, that include a power supply capable of powering a Pentium 4 3Ghz that may be overclocked to 3.5Ghz in the future?
I haven't found any solutions where the case includes a powerful enough power supply. I'm looking to buy from England for about 150 / stg90-100, and thats how I want to buy them, together in one package.


I have been looking at Chieftec Matrix and Scorpio cases which include 360w and 340w power supplys respectively. Are either of those power supplies capable of powering a P4 3.5Ghz?

Hey everybody,
I have a case without power supply switch port and as I already know if I want to replace the power supply I have to find one without an power supply power switch on the back of it and I looked hard on newegg and on tigerdirect. I wanted an antec but thats out of the question because all 20 of them that newegg sells have switchs on them. The only one I found without a switch so far was on tgierdirect and its only 230w and thats what I have now. Also how many watts do you think I should get? Thank you very much

I have a new Aopen AX63pro motherboard (ATX form factor) being shipped from California and wonder if my old AT power supply and case will work with the new board. If I need a new supply, is 300 watts "better" than 235w or 200w? If I need a new case, any thoughts on what's the best value? Does an ATX power supply fit into some AT cases (if there is such a thing) or is a dedicated ATX case/power supply needed?

Thanks to anyone taking time to offer an opinion.

A:Will old AT power supply and case support new ATX mobo?

you will most likely need a new case and power supply. Some AT boards will take either a AT or ATX power supply but I have not seen an ATX board that will do both. There may be some exceptions but it is a good bet that you will need to buy some new equipment.

I built a new pc a bunch of years ago and spent some extra cash on a nice ATX case that I planned on recycling when I built my new new pc, which I'm in the process of doing now.

I found a power supply I want, but it (and most of the other PS's I'd consider) all have top mounted fans where my case supports a back mounted fan. My case has a blowhole in the top center panel, but no vent where the PS would be located. Would this be enough ventilation or should I just stick with a lesser PS with a back mounted fan?

Hi all,

My power supply (Corsair 850W) has a fan at the bottom of it, which i'm assuming was placed there considering power supplies sit at the top of a PC case. However, my power supply holding bay is at the bottom of the case. I was wondering whether it was apt to turn the supply upside down so that the fan was facing upwards (hence expelling air upwards rather than down straight onto the bottom of my case), or whether I should just leave it alone and install as per normal?

This is my first custom build and I don't want to screw anything up!

Any help would be much appreciated

I'm assembling a new system and having power issues. When connected and the switch on the power supply is on, all my components receive power before I press the power switch. Fans turn, DVD drive spins and opens, yet I am not able to power up my computer. I stripped everything down to just the motherboard, CPU and RAM and I still get nothing. No POST beep or anything signaling a startup taking place.

I am wondering if this could be caused by a faulty power supply (ie a short inside the power supply) or more likely by a short in the case somewhere. Any help in resolving this would be appreciated!

A:Power supply/case short issue?

reassemble the minimum system components outside of the PC case on a non-conductive surface (eg the box that came with your motherboard). this will show you if its shorting to the case or an isolated problem.

What brand and model is the PSU?
Reseat all the components (ram, video card, etc).. you might want to try reset the BIOS at this stage since you've got nothing else to do

It is normal for some PSUs to start up the fans and/or other devices for a few seconds after puting in power to it or after shutting down the PC, but irregular if it doesn't die down by itself after a few seconds to a minute or if you can't manualy trigger it (shorting the two pins instead of pressing the power button to turn on the PC)

Hey all,

I want to upgrade my power supply to a 550/600 Watt one, as I want to upgrade to a 640mb nVidia 8800 GTS and I don't think a 450 watt PSU would do it justice with a Core 2 Duo E6600, 2GB Corsair Extreme DDR800 Ram etc, 250gb Sata 2.0 etc..

I was just wondering if there is anything I need to know? If I buy a 550/600 Watt power supply, will I need to buy a new case too? Or will it fit my current case (Currently has a 450 Watt PSU, Gigabyte GA-965P-S3 Motherboard)

Any help is appreciated,

Thanx all

A:Power Supply and Case Upgrade Questions

Measure the size of your current power supply, and look for which plugs and sockets your motherboard requires.
The better quality new power supplies come with everything you need.
Avoid "cheap" power supplies, but there are hundreds that will work fine... FSP, Antec, Color Master, CoolMax, Thermaltake, Apevia, Sparkle, PC Power and Cooling (the best, in my opinion), Raidmax, XCLIO, and most of the ones sold on the more popular websites are going to do the job. I avoid OCZ, and Corsair, Delta, Powerman.... You will find that most power supplies are made by just a few manufacturers in China and Korea. Save your receipt, as even big name, expensive power supplies can suddenly fail.

Hi i was just wondering how many case fans i could use for my CPU with a 4oo watt power supply. They are all antec 80mm fans and are 12v. At the moment i have 4 case fans, 1 processor fan, 1 cdrw, 1 dvd drive and 1 floppy drive. Is this many items safe for a 400 watt Power supply or will i have to disconnect something i.e. the front case fans? Please can somebody reply back with an answer. Thanx

A:How many case fans can i connect to 400w Power Supply?


If I understand what you are saying is that you have 4 case fans and the drives you have listed (not fans for them) in your post. If you have four, you are fine with what you have. Case fans don't actually pull much juice, so don't worry about that. I have heard of people on here who have six, seven, or eight fans. Why? Heavens only knows, because I see not reason to do that. If one sets his air flow up correctly, I can see NO reason to have that many. Kind of like thermal paste, too (much paste) many (fans) can be worse than not enough as you get air through the case in a swirling motion instead of a steady front to back airflow. Well, anyway, that is my personal opinion from building computers.

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?

Yesterday in my house,electric fuse was switched to turn on cooker in my kitchen. During this power delivery was stopped for 4-5 second only.
When power back on then pc automatically turns on and just before bios show me :"?Power supply surges detected during the previous power on ASUS anti-surge was triggered to protect system from unstable supply unit.
Press F1 to continue.? And then pc booted fine to Windows.

Is this normal ? Did it damage something? Why i get that message is this normal?

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?

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

A:Power Supply Wont Power up - Gigabyte ga-ma790fx & AMD Phenom 9850

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.

gfx: Sapphire HD3850 512MB Ultimate (passive)

MB: MSI P35 Neo2 FIR

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?

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.

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.

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

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

What happens if you leave the IR5 connected & shut down the computer, disconnect the IR5, restart the computer. Does your mouse etc. then work properly. If so it might be worth looking at getting a separately powered USB hub & using that for the IR5.

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!

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.

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.

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.

Hi, since the power of my Y3P with display at max birghtness does not hold very long it would like to build a powerbank for it. Since the Power Adapter is 20V 2A I wonder if I could put 4 x 5V (2A) Power Banks in serial and have 20V and enough amps to fuel the Y3P. I also ordered a cable with the right plug to connect to the Y3P. However it has 3 wires inside. When mesuaring with a meter one is ground and two deliver about 5V. How could that be? How would you wire it to power the Y3P. Does anyone has any idea?PS: I know this is gonna wipe warranty.

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 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?

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 - "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.

You have to look closely. Good light and a magnifying glass help. Where the case wires go is actually printed on the motherboard in very small print. Look at the base of the pins in you picture although I'm not 100% sure you're in the right spot. Is it where the old case wires were?

A:Challenge! New M/B - New Case - No power!

There could be a short between the motherboard and case. it might be advisable to pull the motherbaord out of the case and set it up on an antistatic surface. Then only connect the powersupply, CPU with fan, one stick of RAM and the video card. This is enough to get the computer to turn on.

The jumpers mentioned are not the cables from the front of the case. they are little plastic caps that sit over two pins. Make sure the Clear CMOS jumper is in the normal and not clear position and that any Front Side Bus(FSB) jumpers are set right fot the CPU - refer to the motherboard manual for postitions of jumpers.

Are all parts new?

A:Power Supply

well first of all check if your aiw 9700 pro has a molex power connector,i think the 9700 pros do have that,if they do than this has to be connected separately to a free power cable from your psu.200 w is not optimal even if you werent putting in a 9700 pro,you were bound to run into problems if this was a generic psu.since you have a amd 2800+,a 120 g hdd,512 mb ram and also some optical drive(i am guessing)a 200w would not be sufficient for your setup.get a new psu from a respected psu manufacturer like antec or enermax forton.a good psu is a one time thing-put it in and forget it.if your 200 w is a generic brand you really ought to consider an upgrade to atleat a 300w+ psu higher the better(if you ever want to upgrade or put more peripheral in).

If it has made a pop sound then something has definitely blown, it can be a long winded process to figure out exactly what has gone wrong.

The best thing to do would be to remove all but the bare essentials and see if it will boot. Remove hard drive, all optical drives (cd, dvd drives), all cards bar the graphics , and have only 1 memory stick if you have more than 1 that is.

1. I bought 2 gigs of ram

2. An ATI Radeon X1650 PRO AGP 512mb Graphics Card.

3. A new power supply for the graphics card.

The graphics card needs 350W and my current Power Supply has only 300W. The graphics card requires a FDD connector and the new power supply does not have a FDD connector but the old one does. Is their a way I can cut the FDD connector off of the old Power Supply and cut off a not needed connector from the new one and twist the wires together and wrap them in electrical tape.

P.S. If you look at the page for the power supply it says it has an FDD connector on it and there isn't one on it.

I was out of town all this past weekend. I was able to remotely connect to my computer on Saturday but during use, it disconnected me. When I returned home, machine was still one, two fans running, but that's it.

When I turned it off then back on, it doesn't boot, doesn't make that beep sound when you startup. Only two fans come on.

Brought it in to work today and a buddy says he thinks its the power supply because you can kind of smell that semi burnt smell coming from the back of the power supply.
