KHACHIMO 400W 1U Flex ATX Supply

This KHACHIMO DPS-400AB-12A is a new 400 watt ATX power supply in a compact 1U form factor. It targets builders assembling small form factor NAS or server chassis such as the K39 platform. The unit carries 80 PLUS Gold certification and supports Modern Standby for rapid wake times. Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine.

Ideal for Compact NAS Builds

This supply suits integrators who need efficient, quiet power in a 1U enclosure and value zero RPM fan mode at low loads. It is not for builders who require higher wattage for discrete graphics cards or multi-drive arrays beyond the 400 watt limit. Systems needing redundant hot-swap modules or a different physical footprint should look elsewhere.

400 Watt Continuous Output

The single specification that decides fit is the 400 watt continuous rating. Verify that your total system draw under full load stays within this ceiling before purchase.
