5 out of 5 eggsGood

Pros: I see no reason why this is bad, cables are sleaved, extra long, and theres more SATA power ports then any one would ever need.

Cons: Extra long cables take up extra room, but i just shoved them in a spare HDD bay.

5 out of 5 eggsgreat psu

Pros: High quality, quiet, powers a beastly gtx 760, and components, have pushed this so far with marathon gaming sessions without a single issue. Pretty solid well build PSU. Bought due to a positive track record with cooler masters previous gx line of psus.

Cons: no cons!

Other Thoughts: Ive always been a fan of coolermaster psus. I bought this because my old gx performed flawlessly, like a champ. I used this new one in my upgraded gamer build, old gx1 psu is still running solid in my guest gamer pc for when my buds come over. Solid and somewhat quiet. It powers an nvidia gtx 760 w/4gb vram and oc'd, with an amd fx cpu with 8gb of ram, and a 1tb wd blue drive with hoards of case fans and pretty led lights. works like a champ. I would recommend this for high quality gamer builds without breaking the bank. A+
