1U rackmount 300W ATX power supply unit, matte black metal case with rear fan grille and cable connectors

KHACHIMO

KHACHIMO IPC 1U 300W ATX Power Supply GW-EPS1U300HC-YD

SKU CH-0JEM-M6QV8

A 1U ATX unit delivering 300 W with 80 PLUS Gold efficiency, Modern Standby support, a zero-RPM fan mode and resonant LLC topology for clean, quiet power

  • TypeATX
  • Modern Standby support for rapid wake and low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency with less heat and noise
  • Zero RPM fan mode stops the fan at low and medium loads for silent running
  • Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine
  • 300 W ATX output in a compact 1U form factor for space-constrained builds

Compact 1U ATX Power Supply

The KHACHIMO IPC 1U 300W ATX unit fits standard 1U server and slim desktop chassis where full-height power supplies cannot be installed. It is built for system integrators and IT managers who need reliable power delivery in space-constrained racks or small-form-factor workstations.

Gold Efficiency with Semi-Passive Cooling

80 PLUS Gold certification means high efficiency across the load range, reducing waste heat and electricity cost. A Zero RPM fan mode stops the cooling fan completely at low and medium loads for silent operation, while resonant LLC topology with DC-to-DC conversion delivers clean voltage regulation and minimises coil whine.

Replaces Legacy 1U Units Lacking Modern Sleep

This supply upgrades older 1U ATX units that cannot meet Modern Standby requirements, enabling extremely fast wake-from-sleep transitions and deeper low-power states. The jump is worthwhile when deploying fleets that rely on instant resume or when acoustic targets demand fan-less idle behaviour.

  • Zero RPM fan mode stops the fan at low and medium loads for silent running

Questions about this item

What does the ATX form factor mean for this 300W unit in a 1U chassis?

It fits standard ATX mounting holes and delivers 300 watts within a 1U height, so it slides into compatible rack or slimline cases without adapters.

Which physical clearances and connectors must the case provide for this 1U supply?

The case needs a 1U tall ATX power-supply bay with rear exhaust clearance and standard ATX motherboard power connectors.

How is the supply installed and what step do builders often miss?

Secure the unit with the four ATX mounting screws, plug in the 24-pin and CPU power cables, then enable Modern Standby in the BIOS so the zero-RPM fan mode and fast wake functions work correctly.
