Summary: I purchased this power supply on the basis of reviews here at Amazon and other sites, as well as prior experience with Cooler Master products. I was not disappointed. The modular cabling worked very well, power was stable, and the unit was very quiet. However in September after returning from a vacation, the fan got stuck at full speed and the unit became very loud. I discovered that Cooler Master has a FIVE YEAR warranty on power supplies and filed an RMA.
Summary: Honestly this PSU is great for anyone building a PC, however I think I got one with too many watts but oh well. Overall this is a very nice power supply and it runs silently in the background whilst powering all of your components. The cables that come with it are useful for daisy chaining up to 15 drives if your motherboard supports it and 4 GPU's.
Summary: This 850 watt supply replaced a failed 350 watt power supply in my mid-sized tower. It was obviously a bit larger but it fit right in. I love the modular design. Use only the cables you need, and it is very quiet.
