Power Supply Issue: Turns on for .5 sec then does not fully turn on.

I recently blew out my power supply. I upgraded from 600w to 750w, I installed it correctly (I think). When I try to power it up, it gets power briefly(some lights turn on cpu fan spins a little then it does not turn on all the way.
I am not sure what is wrong :(

Thanks in advance

  1. The power supply may not have been the only thing that went, how bad was the blow out? Also what are the full system specs including make and model of the old and new PSU.

  3. My power supply did the same exact thing as a matter of fact. Right after one blew, just like yours. In my case it happened to just be the cable that came with the new power supply. (the one that runs to the wall) Try using your old cable!
  4. Yeah that 600 watt rosewill was really a 450 or a 500 looking at its specs.

    Do you have another computer that you could test some of the parts out in? In particular check the ram, and swap the motherboard for another AM2 one for testing. If it boots with a different motherboard then your mobo got fried, only swap out one part at a time though so you can find the issue.
  5. Ok, I got the computer to turn on tonight.

    First I removed the ram, and this didnt do anything. Then, I removed the power to the graphics card, and bam it turned on no problem.

    What does this mean? Did my graphics card die or is it causing some surge?

    Thanks for your help!
  6. Take that graphics card and try it in another machine if you can, when your PSU died it might have taken the GPU with it and if it caused something in the GPU to short the PSU would shut off to protect itself. If the system you try it in doesnt boot up either you have found your issue, as long as the test system has a good PSU in it it shouldnt pose any risks, but its probably your graphics card at this point. Good excuse to upgrade to one of the newer ones.
