Best PSU for SLI Geforce 8800 640 meg on 681i MB?

[Vythic]

Can some recommend a good PSU for me?
No idea what the min (or rather, recommended) wattage should be for this system.

System will be (the parts I know for sure):
CPU: Intel Q6600
Mem: 2 gig (Corsair - not sure yet)
Video: 2x (1x for now) EVGA 640-P2-N825-AR GeForce 8800GTS 640MB
MB: VGA 122-CK-NF68-A1 LGA 775 NVIDIA nForce 680i SLI
Case: Don't know yet
HD: Raid 0 Sata2 (haven't picked capacity yet), probably 3 drives in system total
Other: DVD DL burner

TIA!

Similar discussion here.

Summary: You could get by with a quality 380W psu (EarthWatts or Seasonic). A Corsair VX450 would be better, and the Corsair HX520 will give you even more headroom. If you plan on o/c'ing your C2Q & maybe doing G80 SLI down the road I would go with the Corsair HX620 ($110 AR @ clubit.com) or maybe a Silverstone ST75ZF. Just a few ideas since your post is a regular FAQ.

I dunno John...he said SLi in the topic...I am not sure a 380W PSU could run 2 8800GTS in SLi...HX520 might....but I would go for the (anythning Seasonic over 550W) Seasonic S12 650W, M12 700W, Corsair HX620, Enermax Liberty 620, Enermax Infiniti 650 a Silverstone 600W+

Using a calculator, I see his rig can use max of 474W, and that's not including fans or USB devices, or extra card ect. I'd say get the corsair HX520 minimum, but I would consider the Seasonic S12 650W if it was my rig.

I totally missed the part about SLI in the topic, but I did mention that SLI would require more juice and offered a couple of recommendations. The PCP&C Silencer 750Q is another popular psu for G80 SLI, and the Antec TP Quattro 850 is an even better option in the same price range ($180).

You guys rock, thanks for the advice.
Yes, I'll definitely be overclocking.. hopefully I'll have more luck with the new system vs. my current one (939 MB, Althon FX-55) - would barely OC at all, even with all high-end parts, etc.
Now I just need to decide on the RAM.. well, and case..
