300W ATX power supply for modern desktops

This 300W ATX unit delivers reliable power for mainstream desktop builds and small-form-factor systems. It meets 80 PLUS Gold efficiency standards for lower running costs and reduced heat. Modern Standby support enables extremely fast wake-from-sleep performance.

Integrates with standard ATX cases and motherboards

The ATX form factor fits standard chassis layouts without proprietary brackets or cables. DC-to-DC conversion with resonant LLC topology supplies clean voltage to modern components while supporting deeper sleep states. Zero RPM fan mode keeps the system near-silent at low and medium loads.

Sustained output with quiet thermal management

Gold-rated efficiency maintains consistent delivery during extended workloads while minimising waste heat. The resonant LLC design reduces coil whine under continuous demand. Fan remains off through moderate loads, spinning up only when thermal thresholds require active cooling.

Questions about this item

How much continuous power can the 300 W unit deliver before protection trips?

The power supply is rated for 300 W of continuous output, so sustained loads up to that level are supported.

Will the fan stay off or run quietly during an all-day workload?

Zero RPM Fan Mode stops the fan at low and medium loads, and 80 PLUS Gold efficiency keeps heat and noise low even at higher loads.

What motherboard power connector does this ATX unit require to function?

It uses a standard ATX 24-pin main connector plus the matching CPU and peripheral cables for a typical desktop board.
