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

1U 300W ATX Power Supply

This KHACHIMO unit delivers 300W of power in a 1U form factor with an ATX design. It carries 80 PLUS Gold certification for high efficiency operation that reduces power consumption and heat output. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power delivery while reducing coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Suitable for compact servers and quiet workstations

Builders fitting a 1U chassis who need Gold-rated efficiency and silent low-load operation will benefit from the Zero RPM fan mode. The DC-to-DC topology supports modern sleep states for responsive wake performance. Systems requiring more than 300W of continuous power or a larger form factor such as ATX PS/2 should look at alternative units. High-density GPU configurations needing multiple PCIe power connectors are not supported by this design.

300W output capacity

The single deciding specification is the 300W rated output which determines whether this unit can handle your components' combined power draw. Calculate total system consumption including CPU, memory, storage and expansion cards against this limit. The 80 PLUS Gold rating ensures efficient conversion at typical loads but does not increase the maximum available wattage. Exceeding this capacity will cause instability or shutdown.
