i cant say enough about the SeaSonic S12 II SS-380GB 380W ATX12V V2.3 80 PLUS Certified Active PFC Power Supply. i dont usually go out an recommend things randomly but this PSU is great. first off, i cant hear a single thing. the fan is super quiet. second, the build design is sturdy as all hell. thirdly, it is inexpensive! check it out on newegg if you are looking for something low power but high quality.
