Techaddicts posted a review on the Seasonic M12 500W Power Supply
During testing, the power supply was unusually quiet, even in the Max Load tests. There were no problems keeping the system stable and running, nor were there overheating problems. The modular cables are wrapped in mesh and really make the insides of the case neater, and the Molex cables feature grips to make removal easier. Overall, this is an excellent power supply for anyone looking for performance and an extremely quiet fan.Seasonic M12 500W Power Supply Review
