Product Description

Cosair CX650M Semi-Modular ATX Power Supply

CX Series Modular power supply units are an excellent choice for basic system builds and desktop PC computer upgrades, offering high reliability, low noise, and easy installation. The flexible modular cabling system lets you use only the cables you need, and 80 PLUS Bronze certified efficiency means less excess heat, lower noise, and lower power bills.
