Cooler Master have been releasing power supplies now for many years and today we are looking at an upgrade to their long standing 650w non modular unit. It receives 80 Plus Certification and a range of internal design changes, with a new Enhance implementation. Cooler Master are also aiming for competitive pricing to target the mainstream enthusiast audience … but is it worth your money? The GX650 we are looking at today is the mid range model in a new series of 550w, 650w and 750w power supplies which are hitting the market this week. They are designed for enthusiast systems with a key focus on performance, while maintaining a strong value for money balance. The new design features a dual layer EMI filter and a large quality 120mm PWM controlled fan.
