  • 80 PLUS Gold certified for 80-plus percent efficiency reducing power draw and heat
  • Zero RPM fan mode stops the fan at low and medium loads for silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 250 W ATX output in a compact 1U form factor for space-constrained builds

Compact 250W ATX Power Supply

The KHACHIMO HK350-94FP is a 250W ATX power supply designed for small-form-factor systems such as 1U servers, NAS appliances, POS terminals and ATM hardware. Its compact dimensions and standard ATX connector layout make it a direct fit for space-constrained industrial and embedded builds.

80 PLUS Gold Efficiency Rating

Certified to the 80 PLUS Gold standard, the unit delivers high efficiency across typical load ranges, reducing wasted energy and lowering operating temperatures. This efficiency level is the primary specification that determines whether the PSU meets the thermal and power-budget requirements of always-on edge deployments.

Semi-Passive Cooling and LLC Topology

A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation for noise-sensitive environments. The resonant LLC topology with DC-to-DC conversion supplies clean, stable power while minimising coil whine and supporting modern standby sleep states for rapid wake times.
