750W is more than enough but I would not buy one from Coolermaster. Coolermaster does not make very good power supplies. Get either a Antec Truepower New, Corsair TX750 v2, HX750 v2, or a Seasonic X750. You might even get by with a 650W version of these psus also. Don't EVER cheap out on the PSU, your parts are too precious!

If you get a Corsair TX/HX series make sure you get the v2 version. They improved it alot with the this second version and is about the same price.

edit: @ post below, I didn't even notice this was in the wrong section until I saw ur comment LOL

I would understand this thread if you had listed anything even remotely related to water cooling. How you managed to post this in the completely wrong section is beyond me.

This really should be moved to the "Power Supplies" section.

T3chAdd1ct is right, Cooler Master does not make very good power supplies, go with one that he suggested. If you aren't sure about a power supply just type it into google with "review" after it, if you don't find credible reviews that's usually a bad sign. You should be fine with a 650W psu as long as you are not planning on overclocking too much.

Cooler Master sells some decent power supplies. These days they tend to all have "Silent Pro" in the name though. Well, GX450 isn't that bad for a budget unit either.

You'd be good to go on a good 550W unit since you're just pushing some lighter overclocks, though 650W would be reasonable to get. The problem is that the GX750 is known to start going out of spec around 400-500W. Whoops. Granted, the problem is "just" minor rail ripple.

OklahomaWolf's first unit they sent him had even more problems than the one he reviewed.

Hardware Secrets review of the GX750 conclusion, last paragraph says "but it is only safe to run this new Cooler Master unit up to 450 W"


The 2x GTX 460 will draw 433W on load according to Guru3Dto .

The i7 2600k @ stock will draw 128W on load according to AnandTech

That's a total 561W and that's before overclocking, so you should definitely get atleast a 650W
