The modular power supplies of the CX series are an excellent choice for basic system builds and computer upgrades for desktop PCs. They offer high reliability, low noise levels, and easy installation. The flexible modular cabling system, 80 PLUS Bronze certified, ensures less heat generation, less noise, and lower electricity bills. The thermally controlled large-diameter fan ensures that the CX series operates quieter at idle and reduces noise when you put your system under heavy load. The matte black finish, black cables, and black connectors give your system a subtle high-tech look.
