CORSAIR CX550 550W 80+ Bronze Non Modular ATX 2.0 Power Supply

The CORSAIR CX550 is a 550-watt ATX form-factor power supply designed to deliver consistent, continuous power for mainstream desktop PC builds. Carrying an 80 PLUS Bronze efficiency rating, it reaches up to 88% operational efficiency, which translates to less wasted energy converted to heat and lower running costs compared to unrated units. Cooling is handled by a 120mm sleeve-bearing fan that is thermally controlled — at light to moderate loads the fan spins slowly for near-silent operation, stepping up only when the unit is under heavy load. The compact 125mm chassis length means the CX550 fits comfortably in the vast majority of modern mid-tower and full-tower ATX cases without clearance issues. Cabling follows a non-modular design with fixed Type 4 cable harnesses. The connector set includes one 24-pin ATX motherboard connector, one EPS 12V CPU connector, two PCIe connectors for graphics card power, and three SATA connectors for storage drives, covering the needs of a typical single-GPU mid-range build. The unit conforms to ATX12V v2.31 specifications. CORSAIR rates the CX550 for a mean time between failures (MTBF) of 100,000 hours, and backs it with a 5-year warranty — a strong assurance for a Bronze-tier unit in this wattage class. Model number for the Indian market is CP-9020277-IN.
