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

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.
