Hey all, I just bought a PNY Geforce 8800GT 512MB and when looking at the box it says that the minimum requirements are a 400W PSU with 26A on the +12V rail. I have a 600W PSU with 18A on the +12V rail. Now, I havent run any benchmark tests on my rig and the only game I have played was UT3 which ran flawlessly on MAX settings on my 22" monitor. Is my PSU bottlenecking my card in anyway? Would a benchmark test confirm this for me? Here is my PSU:
the psu has no effect on bottlenecking, either your card will work or not with the wrong psu
Actually it can, if it's not providing enough clean +12v power for the card to run at full speed you will see lower fps, with a little less +12v power you will start to see random reboots and crashing. And then even less +12v power will cause the card to not operate at all.

If you look at your PSU specs, it's actually got 2 12V rails, each one with 18A. So you shouldn't have any issues.

That doesn't mean anything.
It's the total combined wattage on the 12v divided by 12 = amps
My old Dell 305w psu had 2-12v rails @ 18a each = 22amps (pretty darn good for a 305w)
The 600w psu in question has no documentation (that can be found) on the 12v wattage (besides 2-18a rails)
