What's wrong with it?
I just went with the PSU tier list, and this was in Tier B and also got good reviews.
PSU Tier List will help you to choose the best PSU out of hundreds of models on the market. From budget to the highest end Power Supplies.
I just don't trust Cougar as a power supply brand. Tier B should
be okay, I'd just prefer a Corsair, Seasonic, ASUS Thor, etc.
Cougar won't have made it, they'll have slapped their name on it. Looks to be a clone of the Coolermaster Masterwatt V2, which is an okay
unit, but nothing special.
It won't burn your house down, but in your position, I'd be looking for one from a more reputable power supply brand.
