Cx Series Cx550 Power Supply

The Corsair CX Series CX550 (CP-9020277-EU) is an ATX power supply for a desktop computer. Its 550 W rated output provides power for the system’s components, while the 80 PLUS Bronze rating identifies its efficiency class.

A thermally controlled 120 mm fan adjusts its speed to the load, slowing down when the power supply is under lighter demand. This helps keep fan operation quieter at those loads. At 125 mm long, the unit has a compact profile that can make fitting it into a modern computer case easier.
