3 out of 5 eggsGood for the price.

Pros: -Cheap

-Quiet for the price range.

-Works great for the price.

Cons: -It's not 80+ certified.

-While not having sleeved cables is not a con, having the cables be all one color would have been better.

-Not actually a 550W unit.

-Has a sleeve bearing fan

-The 24 pin cable is a little short even for my NZXT 210. But not worth taking a egg off over .

Other Thoughts: I bought this as a stop gap until I could afford a better PSU. It's cheap, which is a plus and is quiet for the price range. I've put about 50 hrs on it( and will probably put on another 10 before my new PSU arrives) and have had no problems.

5 out of 5 eggsQuiet and Efficient

Pros: This CM Elite V2 550w runs extremely quiet in the mini-ITX build I constructed for a friend. I was a bit hesitant at first since it seems the $50-60 price range these days are littered with 430-500w PSU's, this 550w is topping out at $60. But those fears were washed away with great performance and power consistency!

Cons: The only con that I bring up is the cables, you have very stiff, 'non-compliant' cables. But there is no way that I would take an egg off for that, this is a budget PSU and if I want better looking cables then I should have to pay a little extra for the individually sleeved cables. I would rather have the build quality in the power supply than the aesthetics of the cables at this price range.

Other Thoughts: Cards that run great with this PSU are the GTX 960 (for the green side) and 280X R9 (for the red side). I've used both with this power supply and they worked great!

Thank you CoolerMaster for a great product that doesn't break the bank.

3 out of 5 eggsGood Value

Pros: Cooler Master is a good brand, and I got a great price on this PSU. It works.

Cons: The cables aren't sleeved. That really bugs me, because they are a pain to work with and they look terrible.
