Core 2 Quad Build PSU Question

[achensherd]

I'm building a C2Q system right now with the following projected specs:

Intel Q9300
P45 MBD
8GB DDR2 1066
640GB HDD
4 x 1TB HDDs in RAID 5
2 x HD4870 CF

How much power might this build demand? I tried the Corsair PSU finder already, and it recommends the 1kW model (Intel Quad overclocked, 2 x 4870s, 5 HDDs).

Do I really need a 1kW PSU for this build?

Nah, a good quality 750W PSU should be good enough for that system. Good choices would be Corsair's 750TX or PC P&C's 750W PSUs.
