How much power do u think this computer set would use?
intel core 2 quad q6600 95watt
ASUS P5N-D 40watt
4gig of OCZ 10watt
Nvidia 9800gtx (sli) 230watt
Lite-On Blue-ray 30watt
500gb x1 7200rpm 25watt
80gb x1 7200rpm 25watt
GIGABYTE 3D Galaxy II Liquid Cooling 40watt

Total 495watt?
im just assuming can some correct me if im wrong

The graphics cards can't possibly use total 230 watts. Nvidia is just boasting their products as "powerful."

Btw, see benchmark:

But anyway, get a 600watts psu. That ought to be enough headroom. Keep in mind 12v rail ampage matters too, not just wattage.

enough that a 600W PSU would be a necessity.

o okay so the 9800gtx in sli uses less. thanks for the link with the setup they have they only use 247watt.
intel Core 2 QX9650(333MHzX9)
Asustek MAXIMUS FORMULA
ADATA DDR2-800 4-4-4-10 1T 1GBx2
WD Caviar WD3200YS
Thermalright Ultra-120 Extreme
Silverstone OP1000 1000W PSU

i have an antec 500 earthwatt and i dont want to spend money on another psu so u think i can get away with the 1 i have now. Considering there using a similar setup with 1 less 9800gtx.

It's not useless. 9800gtx in sli is still very good, just not as much as you'd expect, and not for the price.

500watt psu should do, but it's cutting it close. Doesn't hurt to try though.

ya it would be cutting it close but i think it can do the job the antec 500 earthwatt i heard it was very efficient.

Go ahead, it's not like it'll hurt your hardware. At most, the machine will crash and restart under load. Not too late to buy a new one then.

Alrite thanks dagger appreciate the help.

PP&C 610 for that build.
