  • TypeATX
  • Modern Standby compatibility enables extremely fast wake-from-sleep
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • 1U form factor with dual 24-pin connectors fits compact server chassis

Compact 1U Server Power Supply

This new 1U form-factor ATX unit delivers 500 W through dual 24-pin connectors, targeting rackmount servers and dense workstations that require redundant or high-current motherboard power in a single-slot chassis.

Gold Efficiency with Silent Operation

80 PLUS Gold certification and resonant LLC topology with DC-to-DC conversion keep efficiency high and coil whine low, while the Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running in noise-sensitive racks.

Modern Standby Ready Replacement

It replaces older 1U supplies that lack Modern Standby support, faster wake-from-sleep, and Gold-class efficiency; the upgrade is worth it when deploying new motherboards that demand dual 24-pin input and deeper sleep states.

Questions about this item

What does the 80 PLUS Gold rating mean for the DPS-250AB-25B's efficiency?

The 80 PLUS Gold certification confirms the DPS-250AB-25B meets high efficiency standards at typical loads, reducing power draw, heat output and fan noise compared to lower-rated units.

What physical space does the 1U KHACHIMO unit require in a chassis?

This 1U form-factor power supply fits a single rack unit of vertical space and uses a standard ATX mounting pattern, so it installs in any chassis designed for 1U redundant or front-access PSUs.

How do I connect both 24-pin cables on the DPS-250AB-25B, and what mistake should I avoid?

Plug each 24-pin connector into its matching motherboard socket — one feeds the main board, the other the secondary zone — and do not force a single cable into both headers or leave either unseated.
