The 650BQ 650W 80 Plus Bronze Power Supply from EVGA is built with a high-amperage single +12 V rail a 140 mm teflon nano-bearing cooling fan and heavy-duty protection. It's 80 Plus Bronze certified ensuring 85% efficiency under typical loads to conserve power and reduce excess heat. The cables are non-modular so unused cables cannot be removed. Instead organize and keep them out of the way for better airflow within the chassis. Its ATX form factor makes it compatible with almost every standard ATX case.
