What's a good PSU for this kind of setup?

[mathiasschnell]

Here's what I'm more than likely going to get.

CPU - Intel Core 2 Quad Q6600 Kentsfield 2.4GHz - Overclocked to 3.0 GHz

GPU - EVGA GeForce 8800GTS 320MB - Two of these in SLI

HDD - Western Digital Caviar 160GB 7200 RPM

HDD2 - Western Digital Raptor 74GB 10,000 RPM

Mobo - GIGABYTE GA-N680SLI-DQ6 LGA 775 NVIDIA nForce 680i

RAM - Two sticks of G.SKILL DDR2 800, CAS 4-4-4-12, 1GB each

CPU Cooler - ARCTIC COOLING Freezer 7 Pro

Also throw in 2 DVD Combo Drives and 2 SATA drives. No overclocking on the RAM or GPUs. Assume whatever the worst case scenario would be in terms of power draw for everything.

Also, if the extra power draw from the Q6600 being overclocked is a lot and won't bring much extra performance, then I may just not do it.

Edit - I just use the Extreme PSU Calculator, putting in 85% TDP, 20% aging, 2 SATA HDDs, 2 DVD Combo drives, 1 80 cm fan, 1 120 cm fan, 1 240 cm fan, 5 USB devices and the rest of the stuff put here, including the overclocked Q6600. I came up with 649 W.

I think a quality 750 would be plenty. Thinking PCP&C, Seasonic, Enermax, ect.

get a gtx, not 2 gtss', sli doesn't scale perfectly, plus it will allow room for future expansion.

Yeah I'm not sure why so many people wanna SLI midrange cards lately, but it's definitely a bad idea all around

And a quality 600-650w should handle that just fine, don't buy into the oversized psu hype.

You sure that Artic Cooling Freezer 7 Pro is up to the the job of getting that Q6600 to 3GHz?

 

[mathiasschnell]

Would that 600 - 650W do a 8800GTX SLI setup as well?

I wouldn't count on it with the quad CPU and overclocking especially.
