I'm putting together a new build and I'm trying to decide on a power supply.

Everything is going inside a Antec P182 with a Q9450 I plan to overclock. The system will have a total of 7 hard drives in addition to the following components:


Originally I was going to go with:

Corsair CMPSU-620HX 620W http://www.newegg.com/Product/Prod [...] 6817139002

the specs list it as having 8 SATA connectors but I'm worried 620 Watts isn't enough. I definitely want a modular cable PSU with 80% efficiency. Ideally, I'd like to spend under $150 but I can go up a little bit if it's worth it. I was considering these PSUs as alternates:

Zalman ZM750-HP http://www.newegg.com/Product/Prod [...] 6817379006
Antec TPQ-850 http://www.newegg.com/Product/Prod [...] 6817371009

Can anyone help?

Why have you got two different video cards? As far as I know you can only SLI two identical cards.

I expect the Corsair HX620 to have enough juice.

i need to run 3 monitors. the first card (8800) will be the primary monitor but the second won't be doing any heavy lifting so i can go with a cheaper card.
