Will This PSU Handle this System?

The PSU is on this link:

I wonder whether if it can properly handle the following system:

Kingston - Memory - 4 GB ( 2 x 2 GB )
(2x) Geforce 8800GTS Pcie 512MB OC @ 730 SLI
Western Digital WD3200KSRTL Caviar 320 GB SATA 3.5-Inch Hard Drive
7 Case fans
Creative Sound Blaster X-Fi XtremeGamer Sound Card
Intel Core 2 Quad Q6600 @ 3.4 Ghz
Cooler Master RR-CCH-ANU2-GP Gemin II Dual 120mm Fans CPU & Motherboard Cooler
Securdisk DVD+/-rw Dl 20X Beige with 12X Ram Sw
Nforce 680I Lga 775 Dc MAX-8GB DDR2 Atx 4PCIE 2PCI X-fi Aud Esata

On 100% load for hours, is this PSU an overkill for this system, or will it struggle?

Seems alright, will give you room for expansion as well. You will be able to power additional hdds in the future for example.

Edit: I thought I had gone overkill with with my PSU, but then I decided to add more hdds. Now I have an SLI machine, and I am considering a 4th hdd. I back up all my media...

thats fine...since you have sli setup...but you might want to get a more efficient psu if you plan of running the thing 24/7. but nothing wrong with that one

Ok now that everyone here agrees that this PSU can handle this system at full load, I got a 2nd question:

If I changed the PSU by the Thermaltake ToughPower 850 Watts (100 Watts more) , will my system have better performance? Or 100 Watts more would do nothing to the performance (e.g would 3dMark06 score be the same?)

Thanks.

It will not change the performance of the system.. I think the only time performance is changed is if it was previously underpowered (and still worked), but don't quote me on that.Munkyman587
