ATX power supply for modern desktop builds

This unit follows the standard ATX form factor and delivers 500W of continuous power, making it suitable for mainstream desktop systems. It is aimed at builders who need reliable energy delivery for everyday computing, office workloads and moderate gaming configurations. The 12-pin connector layout supports current motherboard designs without requiring legacy adapters.

Sustained load behaviour with Gold efficiency

Certified to 80 PLUS Gold, the supply maintains high efficiency across typical operating ranges, reducing waste heat and keeping internal temperatures lower during extended sessions. Resonant LLC topology combined with DC-to-DC conversion provides stable voltage regulation under continuous demand, while Modern Standby compatibility allows rapid wake-from-sleep transitions without voltage droop.

Quiet construction with semi-passive cooling

Zero RPM fan mode stops the fan completely at low and medium loads, delivering near-silent operation for routine tasks. The LLC resonant design also minimises coil whine, so the unit stays acoustically unobtrusive even when the fan spins up. Standard ATX mounting points ensure straightforward installation in compatible chassis.

Questions about this item

How much noise and heat does the 500W 80 PLUS Gold unit produce when running all day?

The 80 PLUS Gold rating keeps efficiency high, lowering waste heat and fan speed. Zero RPM mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC with DC-to-DC conversion reduces coil whine.

What connectors must my system already provide for this 12Pin 500W supply to work?

The unit uses a standard ATX form factor and a single 12Pin connector, so your motherboard needs a matching 12Pin ATX power socket and the case must accept an ATX-sized PSU.

Will this 500W supply run stably with older components that draw very little power at idle?

Yes. Modern Standby compatibility and the resonant LLC topology with DC-to-DC conversion enable efficient low-load operation and support deeper sleep states on legacy hardware.
