Corsair CX550 550 Watt 80 Plus Bronze SMPS

The Corsair CX550 is a 550-watt ATX power supply built for everyday desktop and entry-level gaming builds that demand reliable, stable power delivery without excess heat or noise. Carrying an 80 Plus Bronze certification, it operates at up to 88% efficiency under typical loads, which means less energy is wasted as heat and your electricity costs stay in check over long usage cycles. Cooling is handled by a 120mm sleeve-bearing fan whose speed is governed by an internal thermal controller. At light-to-moderate loads the fan runs slowly and quietly; it only ramps up when the PSU is under heavy stress, keeping acoustic levels low during typical desktop use. The fan housing measures a compact 125mm in depth, allowing the CX550 to fit comfortably in almost all standard ATX mid-tower and many smaller form-factor cases. The CX550 ships with a full, non-modular cable harness — every cable is permanently attached, so there are no loose connectors to misplace. The connector layout covers a standard ATX motherboard connector, a single 4+4-pin EPS12V connector for the CPU, two 6+2-pin PCIe connectors for a graphics card, three SATA power connectors, and two 4-pin peripheral (Molex) connectors, covering the needs of most mid-range component configurations. Continuous power delivery is rated at the full 550 watts across the operating range, so the quoted wattage reflects real-world sustained output rather than a peak figure. The unit conforms to the ATX12V v2.31 specification and carries a GTIN of 840006670810.
