Summary: It works, provided clean power to all my components. However, this PSU makes a strange grinding sound, like a very loud mechanical hard drive when playing games. Apparently I'm not the only one to have this issue. Returned and bought an RM 750.
Summary: Product was great until after 6 months it failed. I called Corsair and returned power supply, had to wait 3 weeks to receive new power supply. After 5 minutes the replacement (Same model power supply) failed as well. They need to get some quality control on their systems.
Summary: I got the TX 850M PSU and the "M" tag is a complete joke. There are only 4 modular connections and the rest come in your standard mess of power cables. Other then that it's a good PSU and can handle my system really well. My only grip is that: The "M" tag is completely misleading.
Summary: First supply arrived DOA. Have bought two others that worked fine but there is no excuse for out of the box immediate failures. Five stars to Amazon that took the supply back and paid for return shipping.
