Faulty PSU?

Specs: Windows Vista
is my PSU faulty?

Recently installed a new Graphics card and a PSU to support it. Things are fine but whenever I boot after a long downtime, my computer would not pass POST and would reboot itself multiple times to start.

only thing I can tell is different from a normal startup is that it tries to access the cd-drive multiple times (lights there flash a few times)

It's a Corsair 650TX btw

"It's a Corsair 650TX btw"

Apparently listing the video card & rest of the system specs isn't important?

There have been some issues between motherboards and psu's. Some motherboards were taking too long to give the keep alive signal. Dunno who is at fault.

This assumes that the motherboard is really not powering up. Could be that the video is not on too.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

ah sry,

Radeon 5850
Athlon 4600+ (bottleneck ftl)
3 gigs of ram

The video card demands a lot of power but the 650W should of sufficed.

The thing that bothers me is that this issue only happens after a long time it's off. restarting causes no problems. Turning off waiting 2-3 minutes gets no problems as well....

Could possibly be a cold solder joint somewhere. Very hard to trace. Also could be poor contact between wires or components. Try re-seating all cables, cards, RAM. Snap the RAM in and out 4 or 5 times to burnish the contacts. Be sure you fully seat the graphics card and that the lock on the back is engaged. I have see distorted cases or badly formed card brackets pull a card partially out of the slot. Should touch BEFORE the screw is installed.

Do you have a disk in the CD drive?

BTW, do you have the auxillary power to both the graphics card and CPU connected?
