Cooler Master Silent Pro M - 850W Power Supply with 80 PLUS Bronze Certification and Semi-Modular Cables

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).

Overall Review: Like I said above, I'd recommend this and buy it again in a second.

Pros: Semi-modular. Provides the power it says it does and, though standard now, is single-rail. Silent and good LED

Cons: The 4 pin connectors attached to the powersupply didn't work. Connecting them actually shorted out the computer and posed a danger to my mobo. However, the peripheral 4-pin connectors worked perfectly fine. This is a serious problem, however, if you can't test wattage before placing it into your computer as if you had this same issue as I did without testing capabilities, you probably would have damaged your computer.

Overall Review: If you get a fully functional PSU, then it likely is a well-working PSU for you and your system. It's SLI-ready, but I wouldn't trust it for more than two cards or for overclocking. Also, MAKE SURE TO TEST THIS PSU before placing it into your PC to prevent damage. Major con that knocks eggs.
