Corsair CX550 550 watts 80 Plus Bronze Power Supply
The Corsair CX550 delivers 550 watts of continuous power with 80 Plus Bronze efficiency certification, achieving up to 88% energy efficiency at typical loads. This non-modular ATX power supply features a thermally controlled 120mm sleeve-bearing fan that adjusts speed based on internal temperature, maintaining quiet operation during low-to-moderate workloads. With ATX12V v2.31 compliance, the CX550 provides stable voltage rails for processors, graphics cards, and storage drives. Corsair rates this unit at 100,000 hours MTBF for reliable long-term operation in desktop PC systems.
Key Features
- 550W Continuous Power — Delivers 550 watts of stable, continuous output for mid-range desktop PC configurations
- 80 Plus Bronze Certified — Achieves up to 88% energy efficiency at typical loads, reducing electricity consumption and heat output
- Thermally Controlled 120mm Fan — Sleeve-bearing fan adjusts speed automatically based on temperature for quiet operation during light use
