Is This PSU Enought For A 9600 GT? Having Issues . .

It seems I am having both hardware and software issues with my new card. The newest gremlin seems to me to be power related. I installed a 9600 Gt and it the graphics output seems to go kaput under load after a few minutes. The screen goes blank and I get the "shutdown in 5 seconds" message but the motherboard still seems to be powered up and does not shutdown.

I am thinking my power supply is not cutting the mustard. On my rig I have 3 hard drives, a CD/DVD, sound card, network card, USB hub, joystick, two printers, a video card, and of course a monitor. Is that just too much for the PSU in the unit? Here is the unit in question:

Max output seems to be 22A. I thought I read that the card needed 25 amps? I bought the card ahead of new build just to fiddle and I am having problems. I was hoping to transfer my PSU.

Thanks for any input.

 

The printers and monitor have no draw as they don't get their power from your PC. BUT- I would say that PSU is under-powered, esp. for the new 9600GT. I recommend a minimum of 550w with 28a, and IMO that's minimum. I'm sure some other folks out there will offer some opinions too, but I think we can all agree that the current PSU isn't enough.
