Corsair CX550 550W 80+ Bronze Power Supply

The Corsair CX550 delivers reliable 550W continuous power with 80+ Bronze certification, achieving up to 88% operational efficiency for reduced heat output and lower energy costs. This ATX power supply features a compact 125mm length design that fits easily into most modern PC cases while providing stable power delivery for your system components.

Efficient Power Delivery

With 80+ Bronze certification, the CX550 maintains up to 88% efficiency during operation, minimizing wasted energy and heat generation. The single rail design provides full continuous 550W power output, ensuring consistent performance under demanding workloads. Active PFC (Power Factor Correction) and compatibility with ATX12V 2.4 and EPS12V 2.92 standards guarantee broad system compatibility.

Thermally Controlled Cooling

The 120mm rifle bearing fan operates with intelligent thermal control, adjusting speed based on system load. Under light loads, the fan runs quietly at lower speeds. When power demands increase, the fan automatically ramps up to maintain optimal operating temperatures. This adaptive cooling approach balances thermal performance with acoustic comfort.

Comprehensive Connectivity

The fully wired cable configuration includes 1x ATX 24-pin motherboard connector, 1x EPS/ATX12V 8-pin (4+4) CPU connector, 2x PCI-E 8-pin (6+2) graphics card connectors, 3x SATA connectors, and 2x PATA connectors. Black sleeved cables and powder-coated black casing integrate seamlessly with modern PC builds. Universal AC input accepts 100-240V for worldwide compatibility.
