Compact 1U 250W ATX power supply unit with gold finish

KHACHIMO

KHACHIMO GW-EPS1U250HC-DH 1U 250W power supply

SKU CH-PK4X-MBRN0

A 1U 250 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for quiet, low-power operation

  • TypeATX
  • Modern Standby support for instant wake from sleep
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode gives silent running at low load
  • Resonant LLC topology delivers clean, stable power
  • DC-to-DC conversion enables deeper, efficient sleep states

1U 250W ATX power supply for compact servers

This KHACHIMO GW-EPS1U250HC-DH unit fits a single 1U rack slot and delivers 250 watts through a standard ATX pin-out. It targets system integrators building space-constrained servers or workstations that require reliable AC-to-DC conversion without exceeding the slim chassis height. Buyers needing redundant or hot-swap power modules should look elsewhere.

80 PLUS Gold efficiency at 250W sustained load

The supply carries 80 PLUS Gold certification, meaning it meets the programme’s efficiency thresholds at typical server load points while outputting its full rated 250 watts. This single figure confirms the part can run continuously at nameplate power without dropping below the certified efficiency curve. Installations that demand higher continuous wattage cannot use this model.

Resonant LLC with DC-to-DC and Zero RPM fan

A resonant LLC primary stage paired with DC-to-DC secondary regulation keeps voltage ripple low and suppresses coil whine during prolonged operation. Under sustained low-to-medium loads the fan remains completely stopped, eliminating acoustic noise in quiet rack rooms. At higher continuous loads the fan engages to maintain thermal limits without throttling output.

Questions sur cet article

What does the 80 PLUS Gold rating mean for everyday power draw?

The 80 PLUS Gold badge certifies high efficiency across typical loads, so the unit wastes less electricity and generates less heat than lower-rated supplies.

How does the ATX form factor limit where this 1U unit can be installed?

ATX specifies the connector layout and mounting holes; the 1U height fits rack or slim cases that accept standard ATX power supplies.

What clearance does the 1U chassis need for mounting and airflow?

The 1U profile requires a single rack-unit slot with front-to-rear airflow space; ensure the case or rack shelf provides that depth and venting.
