Does this look right?

I used this calculator to guess what my power requirements would be
http://www.extreme.outervision.com/PSUEngine

It says that my total usage would only be 379 W, which seems low to me but it seems to have taken everything into account(as per my sig but it would be with 2 x 7900 GS in sli)

Any comments would be appreciated.

Cheers

The calculator is wrong. It's a bit less than that, actually. I'd guess the actual draw is around the 200-250w range full load.

hows is that possible? I did some more research and found a classification for what nvidia describes its sli needs;

Mid-Range SLI PC Configuration:
Dual GeForce 8600 GTS, 7900 GT, 6800 GT, or 6800
Intel Core 2 Duo or AMD Athlon 64
NVIDIA nForce 650i SLI or NVIDIA nForce 570 SLI motherboard with 1GB system memory
Single HDD
Two optical drives
PCI sound card
LCD at 1600x1200 resolution

Mid-Range SLI PC*:
Minimum of 450-500W Power Supply with a minimum of +12V @ 26A for all PC components.

Because they assume a crappy PSU that can't actually hit the power requirements it claims and stay in spec.
