Everything seemed to work fine with each other- I plugged everything in after watching nurmerous videos and reading a lot on the forums and everything seemed great but now I am getting the dreaded 1 second CPU/CASE fan spin and power down. I ended up detaching everything and even taking the MOBO out of the case onto a cardboard surface with just the PSU plugged in and same deal. Sorry if this is super newbish but any help?


edit: now I notice with the PSU out of the case the fan on the PSU dies at the same time/speed as the CPU one - would that deem that its a PSU problem?

there you go.did you try testing the psu alone.

Honestly it sounds like a PSU issue to me. I usually have a few PSUs around that I can test with so I can usually tell pretty quickly if that's the problem. I see that you got a 430 watt PSU for your build. That should be sufficient. The video card does state a minimum of a 400 watt PSU to run but you do have to factor in your other parts as well.

I also saw this issue when motherboard wasn't installed in a case correctly with spacers and it was causing a short. However, you said that you've removed it and tested and run into the same issue.

Both the 4 pin and 24 pin connectors are plugged in, correct? Are all of the jumpers in the proper locations (namely the clear CMOS jumper)?

Sounds like there is a short somewhere. The question is where. Could be in/on the board, could be in the power supply.

How are you powering it up outside the case?

I've seen similar issues with a faulty power button on the chassis... i.e. powers on, but essentially acts like it is being held down... so shut down again after a few seconds...

 

[sdougal]

...fairly rare situation, sure, but people are (quite correctly) assuming a PSU when in fact it's a flaky 'on' button.

BTW you can pick up a PSU tester for a few bucks...

Best investment I ever made...
