Corsair CX550 80 PLUS Bronze Certified 550W ATX Power Supply Non-Modular Design, Low-Noise 120mm Fan, Reliable Essential PSU
Reliable and Efficient Power for Everyday Computing
The Corsair CX550 is an excellent choice for users building or upgrading basic desktop systems that require consistent and reliable power delivery. With a 550W output, it provides ample overhead for modern mid-range components, ensuring your system remains stable during daily tasks, office work, and light gaming. Built with the high standards expected from the Corsair CX series, this power supply unit offers a balance of affordability and performance, making it a go-to solution for budget-conscious builders who refuse to compromise on the safety and longevity of their hardware components.
80 PLUS Bronze Certified Performance
Efficiency is a core feature of the CX550, which carries an 80 PLUS Bronze certification to guarantee up to 88% operational efficiency at typical loads. This certification ensures that the power supply generates less waste heat, which in turn reduces the strain on your system's cooling and can lead to lower energy costs over time. By maintaining high efficiency across a range of power draws, the CX550 provides the steady DC voltage required for sensitive motherboard and storage components, ensuring that your PC runs smoothly without unexpected shutdowns or power-related performance throttles.
Low-Noise Operation and Compact Design
Quiet operation is achieved through a thermally controlled 120mm sleeve bearing fan that only spins up as needed. The fan curve is specifically tuned to reduce noise levels during low-load periods, ensuring that your workspace remains quiet during web browsing or document editing. The compact 125mm-long casing is designed to fit easily into nearly all modern ATX computer cases, providing plenty of room for cable management even in smaller chassis. Its sleek black finish and black-sleeved cables provide a clean, professional aesthetic that blends perfectly into any internal PC environment.
Guaranteed Reliability and Comprehensive Protection
Safety is never an afterthought with Corsair, and the CX550 includes a full suite of industrial-grade electrical protections to safeguard your investment. These include Over Voltage, Under Voltage, Short Circuit, Over Temperature, and Over Power Protection, which act as a shield against electrical irregularities from your wall outlet. With a high mean time between failures and a robust internal build quality, the CX550 is designed to provide years of worry-free service. It is a dependable heart for any home or office PC, backed by Corsair's global reputation for quality engineering and customer support.
