DanielG27 Posted February 23, 2011 Posted February 23, 2011 Hi everyone, like the thread title says, I think my PSU is broken. I recently ordered a PC for my parents. Yesterday the parts came in the mail and I assembled the computer. All went well, I installed Win7 without any problems. Then some basic too (Office, VLC, Avast Antivirus). After these installs I was briefly looking at a video on Youtube. While the video was playing all of a sudden my screen went black, even though everything was still running (fans were running). I restarted the computer and the intro screen from the motherboard came up but froze. I restarted it again and now nothing came up any more. I didn't hear any POST-beeps either. Now I went through all the normal elimination stages (remove RAM, 1 RAM-stick, remove HDD,...). All to no avail, finally I decided to see if it was the PSU, by hooking up my PSU I have in my custom build (Antec Quattro 850W). Started up no problem with that PSU, I kept the computer on for about 1-2 hours, working on it and it didn't shutdown. Can I assume then that it is my PSU? I also tested the PSU in my build and it wouldn't start just gave a long, continuous BEEP sound from the motherboard. Is it the PSU? Or could it be something else? These are the specs of the PC: - Processor - 1 x AMD Athlon X4 II 640 / 3 GHz - AsRock 880GMH/USB3 R2.0 - Motherboard - Samsung SpinPoint F3 Desktop Class HD502HJ - Kingston ValueRAM - Memory - 4 GB: 2 x 2 G - Antec TriCool - Case fan - 80 mm 300 502 687 1924 - Xigmatek Asgard III - Mid tower - ATX - Corsair VX450W - Power supply (internal) - ATX12V - Sony DVD Drive - D-Link Wireless Adapter Another question, so I would have to return the PSU, I have an old HP (Hewlett-Packard) desktop still standing here. Would I be able to take the PSU out of that one and stick it in this new build? It says Max. 300W on the PSU. This would only be temporary until I get my new PSU. Would this work or should I not risk it? Thanks in advance for your help, Daniel Share this post Link to post Share on other sites More sharing options...

paulktreg Posted February 23, 2011 Posted February 23, 2011 The 300W unit would run that OK but as for risking it, that's up to you. How many amps on it's 12V rail? Share this post Link to post Share on other sites More sharing options...
DanielG27 Posted February 23, 2011 Posted February 23, 2011 Um from what I can read on the +12V rail there is 19A on it. Also from the situation you read, do you think it's the PSU? Share this post Link to post Share on other sites More sharing options...
paulktreg Posted February 23, 2011 Posted February 23, 2011 The VX450W should have no problem and if you've tried another power supply and it works what else could it be? Your on the edge with only 19A and if the HP power supply is getting on a bit it may not now be able to deliver that so wait until you have a replacement.

The_Slayer Posted February 25, 2011 Posted February 25, 2011 If you have a voltmeter, you could test out the voltages going through the wires and see if one of them isnt right. From what you have said though, I would go with it being the PSU. Since you just ordered it, it shouldn't be hard at all to RMA it.
