5 out of 5 eggs3 Years later

Pros: Very quiet, got all the cables you need, and most importantly, it lasts a long time.

Cons: None really, other than would prefer to have less SATA cables

Other Thoughts: Despite this being a non certified PSU, it is a very solid PSU that I use to this day for gaming!

5 out of 5 eggsOne of the best PSU's I have ever owned!

Pros: I bought this PSU 7 years ago for a basic WoW-computer and this PSU endured heavy use as a gaming computer for 6 1/2 years and finally being retired to a home movie server before it ran another 6 months before finally dying.

This product has definitely changed my mind about the overall quality of Cooler Master and their products, I will definitely be buying the new model of this exact PSU!

Cons: None that I can think of.

5 out of 5 eggs

Pros: Used in a media server that runs 24/7 with no issues for about a year now. 100w CPU, 16GB DDR3(2 x 8GB), SATA DVD drive, 1 x 500GB SATA III HDD, 5 x 2TB SATA III HDD.

Cons: Not enough SATA power connectors so I had to use 4-pin adapters. Still works good though.

4 out of 5 eggsDied

Pros: Quiet. Worked well while it worked.

Cons: Had it for 2 years and 7 months. no where near the 100,000 mtbf. It died quietly, and cooler master just said I was out of luck, which is understandable. Would be 5 eggs if it had kept working. I'd personally reccomend one of cooler masters more expensive models.. Better caps and such make an unfortunate death less likely.

Also, extremely tight sata and molex connectors, and most of the cables are shorter than you'd want them to be, I would think.

Other Thoughts: I buy cooler master for everything I can, and this isn't the first time the product has failed to meet my expectations. They usually break convienently right after the warranty, though.

5 out of 5 eggsGood quiet PSU

Pros: This is a decent power supply for the money. I got one for my main PC and so far I am quite happy with the way it has performed. The fan is very quiet, which is a big plus for a machine that in on most of the time. For the price, this is hard to beat.

Cons: The only thing I don't like is the fact that not all the wires are sleeved. This is not the biggest deal, but neatness is cool. Physically this power supply seems to be a bit small. Even though it does not fit as snug as my last one, once secured in place it is fine.

Other Thoughts: For the price this is an excellent value and it has been running my PC nicely. NewEgg delivered it fast too!
