Is 650w enough for this build?

[ModernClash]

I am currently going to buy a build, but I am not sure if this would be enough?
It is a Corsair Gaming Series 600W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139036&Tpk=CORSAIR%20Gaming%20Series%20GS600%20600W

Would this be enough for this build with a 7850, I might plan on overclocking. If then which PSU should I get?

You don't even need a 600w for that build. A 500w would be fine.

Excellent quality PSU.

BTW, your RAM heatsinks will interfer with the CPU cooler.

A 400w would be more than sufficient, but if your planning to overclock, I would recommend a 500w psu.

What does that mean? Would I have to get different RAM?

Use your RAM in slots 2 and 4 (if slots are laid out in this fashion - 1, 2, 3, 4). That's what I personally do and I don't run into any interference issues with my 212+.

If you plan to use all 4 RAM slots, then yes, you would want to swap out your RAM for something else. Corsair Vengeance Low Profile are a VERY nice choice.

Yeah. Just get lower profile version of that RAM.
