Which PSU for my build?

Intel Q6600 Quad core
SLI 8800 GT Superclocked 512MB
2x1GB Corsair DDR2 800MHz SLI Certified
eVGA 680i
Antec 900
Seagate Barracuda 7200 SATA 400GB
G15 Keyboard
G5 Mouse
After market fans, still to be determined

Any suggestions?

this is something that u dont want to skip out on. I would look for over kill. PC Power & Cooling is what i have and i think OCZ makes them and OCZ is putting out killer stuff right now along with the people that make your case.
Thermaltake is a great company too.
so,
PC Power & Cooling
OCZ
Antec
Thermaltake
or some company with a good name. you want to make sure and get something that has a high amp rating on the 12V rail.

Corsair HX620?

I vote for all corsair models.

Modular?
Budget?
Ocing?

Don't get the GameXStream PSUs by OCZ, not killer stuff at all....



Yeah CorsairHX620+ is good.

If I were going to overclock a quad, I would opt for more power.
