550 W ATX power supply for modern desktops

This 550 W ATX unit delivers 80 PLUS Gold efficiency and Modern Standby support for fast wake times and low-load savings. It suits mainstream PC builds that need reliable power without excess capacity.

Verify ATX fit and cable reach before ordering

Confirm your chassis accepts a standard ATX power supply and that the fixed cables reach your motherboard, CPU and graphics connectors. The unit uses a resonant LLC topology with DC-to-DC conversion for stable voltage regulation.

Gold-rated efficiency with semi-passive cooling

Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. The resonant LLC design reduces coil whine and supports deeper sleep states for everyday quiet performance.
