500W 80 PLUS Gold 1U PSU

The KHACHIMO DPS-500YB B is a 500 watt ATX power supply built to the 1U form factor. It carries 80 PLUS Gold certification for high efficiency and includes Modern Standby compatibility for fast wake times. The unit uses a resonant LLC topology with DC-to-DC conversion to deliver clean power and reduce coil whine. A zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Compatibility checklist

Verify that your chassis accepts a 1U power supply and that the ATX connector layout matches your motherboard. Ensure the total system power draw stays within the 500 watt rating. Confirm the available cable set covers all required connectors for your graphics card, storage and peripherals. Check that the physical dimensions suit your rack or case mounting points.

Build integration

This supply fits compact server or workstation builds where a 1U height is required. Its high efficiency lowers heat output, easing cooling demands in dense enclosures. The zero RPM fan mode keeps acoustic noise minimal during idle or light workloads. DC-to-DC conversion supports modern low-power sleep states without needing extra components. The resonant LLC design helps maintain stable voltages across varying loads.
