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:

If my PSU is bottlenecking my card are there any PSU's that you guys can recommend to me given my setup. Thanks

I guess this PSU should do the trick nicely.

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)

Which is the reason it never made the old reference list. If it isn't rebooting or shtting down, you have enough power.
