How much Power?

[markjonesx]

I'm awaiting the parts for my new rig (SLi), however, I'm a little concerned wether I have a big enough PSU;

850W Enermax EGA850EWL Galaxy Modular PSU

to run the following;

Intel Core 2 Extreme Quad-Core QX6700
Zalman CNPS9500-AT Intel LGA775 Aero Flower Cooler
EVGA 122-CK-NF68-AR NF680i SLI
2 x 768MB EVGA 8800GTX KO Superclocked PCI-E

Anyone know if I have enough juice or is there a good site which can calculate the requirements?

Intel Core 2 Extreme Quad-Core QX6700 ~ 304W Load
768MB EVGA 8800GTX KO Superclocked ~ 327W Load

At first i thought your PS should definitely handle that, but after checking a few websites, it doesn't seem like it'll be enough if you end up putting the cpu and both video cards under full load. You might end up running into stability issues. That's a power hungry system.

I may be missing something, besides the fact you'll be running 2 of those video cards, and if i am, i'm sure someone else could chime in.

you can get addon psu for just powering vid cards now. kinda neat.

The 850 is plenty to handle that. Even a 700 would handle it.

The QX6700 running stock voltage and speed is drawing nowhere near 300W. Heck I had mine o/c to 4.0GHz for testing (1.5V actual) and the draw wasn't that high.

That's right. I misread what i found. That was total system power the person had. ~120W is what it's looking like for the cpu.
