Compact 400W Gold Flex ATX PSU

This new KHACHIMO power supply delivers 400 watts through a Flex ATX form factor suited to small chassis such as 1U servers, NAS builds and compact ITX cases. It carries 80 PLUS Gold certification for high efficiency at typical loads.

Zero RPM fan and LLC resonant topology

A Zero RPM mode stops the fan completely at low and medium loads, giving near-silent operation in noise-sensitive environments. Resonant LLC topology with DC-to-DC conversion supplies clean power, reduces coil whine and supports modern sleep states.

Modern Standby ready for instant wake

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency, ideal for always-on NAS or workstation duties. Builders needing higher wattage or standard ATX dimensions should look elsewhere.

商品問答

What does 80 PLUS Gold certification mean for this 400W supply?

The 80 PLUS Gold rating confirms tested efficiency levels that reduce power draw, heat and fan noise compared with lower-rated units.

What form factor and connectors are required to fit this Flex ATX unit in a 1U or ITX chassis?

The supply uses the Flex ATX footprint and includes the native DPS-400AB-12/17 connector layout designed for small 1U, ITX and NAS enclosures such as the GEN8, K39, S3 or M24 platforms.

How is the unit installed and which step is most often missed?

Mount the supply in the chassis using the Flex ATX screw pattern, attach the motherboard and drive cables that match the DPS-400AB-12/17 pin-out, then enable Modern Standby in the system firmware so the zero-RPM fan mode and low-load efficiency features activate correctly.
