Manufacturer Limited Warranty period (parts): 5 years
Manufacturer Limited Warranty period (labor): 5 years
Cooler Master adds the M850 to the Silent Pro series, giving extreme overclockers and/or ultra high-end systems all the power they need. With up to 66A on a single 12V rail, these power supplies deliver where it counts and won’t have any problems powering even the most demanding multi-graphic card systems. These units feature flat modular cables for improved airflow and cable management. It also comes with shock absorption silicon pads to remove possible vibrations.
Pros: It has quality components, all the power you need, and is modular. Almost completely silent operation too - much quieter than any other fan in your system. I can't hear it at all. It comes with two rubber frames to keep the PSU from vibrating during higher fan speeds. I'd definitely buy this again if I needed this much power for another build. Any PSU in the Silent Pro line will probably be just as good... I highly recommend this if you're looking for a quality PSU with good cable mgmt properties.
Cons: The rubber frame piece is a little tricky to get on at first, but once it's on, it stays put. It's not 100% modular - the 20+4 and the two 4+4 power connectors are permanently attached (everything else is modular however).
Other Thoughts: Like I said above, I'd recommend this and buy it again in a second.

Pros: Modular, you only plug in what you need. Quiet! My DVD and CPU fan drive make more noise than this PSU. Stable voltages. Room to upgrade.
Cons: Price? I'd say that, but with PSU's, you really do get what you pay for.

Cons: Ordered one, it arrived doa and killed my motherboard so i had to rma both. I received the second power supply and motherboard and the power supply was doa again. This killed the motherboard a second time. Now i have switched to a Kingwin 1000watt psu and it works great.
Other Thoughts: I think cooler master is a great company. Their customer support is excellent, but their quality control on their power supplies seems to be very lacking.

This user purchased this item from Newegg
Pros: This power supply has a great watt output and a great top amp draw. It is a very good looking psu and has a heft to it that makes it feel very solid. Also there are plenty of plugs and the modular build makes for a clean case install. Plus there are 2 rubber dampeners to help control vibration and noise
Cons: My item arrived doa but i have gone through the rma process to replace it.
Other Thoughts: From what i could tell from the fan on this unit is amazingly quiet.
