[Solved] I need an opinion on what PSU to get for this build.

Forum Systems : Homebuilt [Solved] I need an opinion on what PSU to get for this build.

I have been banging my head against the wall trying to figure out how large of a PSU to get.
Let me put up what specs I plan on putting into this build:
CPU:
i5-2500k
GPU:
Radeon 6970 CrossfireX
RAM:
Mushkin Radioactive (8GB) 2 x 4GB 1600MHz .......(possibly will double this)
MOBO:
MSI P67A-GD65 (B3) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
HDD:
Seagate Barracuda 1TB 7200RPM

and just some sort of CD burner, idc about that. And also I'm going to have about 6-8 fans depending on the case I get, even though they don't draw too much power.

I do wanna do some light overclocking processor-wise, not so much on the 6970s because honestly they won't need that much help.

Is 1000w worth the money? or is something like 800w plenty of power for this type of build? let me know your opinions and thank you in advance.

Ok.... let's see;

i5 2500k = 95W TDP
ATI 6970 = 250W Max Power Draw Each. Since you crossfire, that's 250W x 2 = 500W Max
Mobo, Ram, HDD, Optical Drive + misc = another 150W [Somewhat of an over-estimation - just to be safe]

That's about 750W - Which is why I would recommend a Corsair 850W Enthusiast [Bare minimum]. Although a 950W would be the best choice imo.

Note: It would be quite difficult to get both cards to run at 100% but it never hurts to be safe and to have some headroom for more RAM, blue-ray drive, hard-drive(s) and SSD(s).

Your very welcome - just to make sure to get one of the models I specified because Corsair makes the best PSUs, period.

Your way high on the rest of the system. A quality 850W will do fine.
