Introduction
Cooler
Master is electrifying gamers PCs with GX 550W, GX 650W and GX 750W
power supplies, specifically targeted at systems in the upper-mid to
high-end range, yet reasonably priced, providing users with unsurpassed
cost per performance. The Cooler Master GX Series of power supplies
feature a single highly robust 12 V rail, proficiently
delivering power to the most demanding components including the
processor, drives, cooling fans and even the most intense dual graphic
cards, such as the SLI or CrossFireX. Now including a double-layer EMI
Filter, an intelligent 120 mm
controllable fan and an active PFC/PWM combo controller for increased
efficiency, the GX Series will keep the power in your hands.
Features
