Help choosing the correct PSU

[BeernuT]

About to build a new opteron system for gaming using the following components

Asus A8N32-SLI
Opty 175
2x1GB - G.Skill PC4000
2 x 7800 or 7900 Nvidia cards
1 10k 78g raptor
1 7200 200g seagate


I'm currently considering these 3 psu's atm:
Newegg PSU comparison

SILVERSTONE SST-ST60F ATX 600W Power Supply 90 - 264V - Retail
PC Power & Cooling 510 SLI-PFC ATX12V 510W Power Supply 90 - 264V UL/ ULC/ TUV/ CE - Retail
ENERMAX EG851AX-VH(W) FM EPS12V 660W Power Supply 90 - 264V UL cUL VDE DEMKO NEMKO SEMKO FIMKO - Retail

Just wondering what your thoughts were on these 3 PSU's. I like the modular design of the silverstone, but it isnt something I have to have for this build. I know pcp&c is highly regarded. I will also be OC'ing this system.

thanks

PCP&C 510 from PCP&C, not newegg.

PCP&C 510ASL (24 pin main, 8 pin aux, 2xPCIe SLI 6 pin)

even if you have a 4pin aux mobo get the 8 pin aux
it will attach directly given clearence, some new gaming boards are employing the 8 pin already, the ATX12V spec will likely adopt it soon

and if there isnt clearence buy an adaptor
or simply a 4 pin connector and repin it saving the 8pin connector and capping the extra 4 wires for a rainy day

I have an EPS12V 2U supply (24 pin + 8 pin) powering an antique Shuttle \Cleron 600MHz
if there is clearence its all the same connector keys, 24 fits 20, 8 fits 4, they just hang off
