Product Overview

550W 80 PLUS Bronze ATX Power Supply

Complete Specifications & Features

PSU

A 550-watt, 80 PLUS Bronze certified, non-modular ATX power supply. It features a quiet 120mm fan, a single +12V rail delivering 44A, and is designed for reliable, continuous power delivery for mainstream desktop PCs.

A "550W Normal" power supply is a standard ATX power supply unit designed for mainstream desktop computer systems. It delivers 550 watts of continuous power, which is sufficient for most mid-range gaming PCs, home office desktops, and general-purpose computers.

The unit features an 80 PLUS Bronze efficiency certification, meaning it operates at up to 88% efficiency under typical loads, reducing wasted energy and heat. The "Normal" designation typically indicates a non-modular design, meaning all cables are permanently attached to the unit. While this can result in more cable management within the PC case, it also makes the power supply more affordable and straightforward to install.

Cooling & Safety Protections

The 120mm low-noise cooling fan ensures quiet operation under normal loads. A single +12V rail provides 44A of current, delivering stable and reliable power to all critical components, including the CPU and graphics card. With built-in protections (such as over-voltage, over-power, and short-circuit protection) and a warranty, this power supply offers a reliable foundation for a budget-conscious PC build.
