The Corsair CX Series CX550 is a 550 W power supply unit designed for standard PC builds. It provides stable power delivery with a 24-pin ATX connector, supports 100–240 V AC input at 47–63 Hz, and features a compact 125 mm depth casing to fit most modern computer cases. The unit uses non-modular cables and includes a thermally controlled 120 mm fan with active cooling to maintain operating temperatures. The CX550 holds an 80 PLUS Bronze efficiency rating to reduce energy loss and heat generation.

Advantages

The CX550 offers up to 88% operational efficiency under typical loads thanks to its 80 PLUS Bronze certification, which lowers energy consumption and heat output. Its thermally controlled 120 mm fan adjusts speed according to load for reduced noise during light operation. The compact 125 mm-long casing allows easy installation in most modern PC cases, and the 24-pin ATX connector ensures compatibility with standard motherboards.
