Ive just installed my new PSU (Corsair TX 650W) after my old 1 died on me, Ive plugged everything in and then pressed the on button. All the fans start powering up and then after about 0.5seconds everything cuts out? I could only think of a few problems, either something is short cuirciting, or it is underpowered, or it could be worse and something could be fried!!?
My spec is as follows:

Intel Q6600 Core 2 Quad @ 2.4Ghz
Antec 900 Case
Asus P5N32 E-Sli Plus Mobo
Corsair 2Gb XMS2 PC6400
EZCool 650W PSU
BFG 8800 Ultra
Seagate 160Gb 7200rpm SATA HDD

650W should be enough power for this shouldnt it? Please can you give me your ideas or suggestions on what to do.

thanks

650W is more than enough. This could be an overload or short. Disconnect everything not required to POST (including your hard drive) and see if you can at least get that far. If so, then add one thing back at a time (with power OFF, of course), until the symptoms return; you will have found the defective component. If it won't even POST, then your mobo may have a short. You can try taking everything out of your case. If that works, re-mount everything in your case, taking care that the mobo is on standoffs, and that there are no extra standoffs screwed into the case where there is not a mounting hole. Finally, run a strip of tape along the back edge, where loose PCI slot covers may be hitting something.

Oh, and what CPU cooler do you have? 0.5 seconds is awfully quick, but your CPU could be overheating if the cooler has popped loose.

I had the same problem. Finally replaced the CMOS battery. The PSU was also done for, but those two replacements fixed the problem.

no luck so far i have tried removing and re-attaching the stock cooler, replaced the CMOS battery and unplugged the power too my GFX card (which then beeped at me), hdd, optical drive; so that the only power cable that was left was the mobo and it still did the same thing. Any other suggstions :|

*Edit, the fans stay on for about 1second, and i read that if u remove the stock cooler the thermal pad is destroyed, i did not reaplly any thermal material, does this sound like it could be overheating?

You should clean off and re-apply new thermal compound.
Plug the power back into the graphics card, but no other perepherals.
