Hi beerme!!

Welcome to nvnews.net!! How many 12v rails come on your psu? How many lights/leds, fans etc are running? This will help you. This is a Psu calculator through extreme systems. In my experience its about 90% accurate. Good Luck!!

I'm using the Ultra X3 1000W with 9800GX2 Quad SLI, works great. Single 12V rail is the best.

I only need a 304w PSU :wtf: LMAO.... I think I went a little overkill

EDIT: make that 296w

Mine came up at 330W. LOL Guess my Antec NeoHE 500W is plenty. ;)

I had to pick the AMD X2 3800+ under Socket 939, because they don't list the 3600+. :thumbdwn:

EDIT: 435W if I add two 8800GT 512MB cards in SLI. The above 330W is with me running my wife's 7600GT.

Mine says 488W.

I got a 700 just in case I ever "needed" to go SLI. :p

According to the calculator I'd need 601 watts to go SLI with my current card.

They haven't added 9800GX2 to the list of GPUs yet, so I selected 8800Ultra, and CPU with 100%TDP, and it came up at 596W. The GX2 max power draw is about 15-20W highter than that of the 8800 Ultra, so probably 636W.
