Compact 1U Power Supply for Small Form Factor Builds

This 500 W unit fits the 1U K39 form factor and carries 80 PLUS Gold certification for high efficiency. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Straightforward ATX Installation

Standard ATX connectors make installation familiar for experienced builders working in compact cases. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. The main difficulty is cable routing in tight 1U enclosures where space for bends is minimal.

Suits Silent Compact Systems.

Ideal for small form factor PCs, home theatre builds, or office workstations that value low noise and efficient sleep states. Builders who need more than 500 W for multi-GPU setups or heavy overclocking should look at higher-capacity units. The 1U height also rules out standard ATX tower cases that expect full-height supplies.
