  • TypeATX
  • Modern Standby support enables extremely fast wake-from-sleep times
  • 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
  • 20-pin plus 10-pin connector layout fits 1U form factor systems

1U 250W 20Pin+10Pin Power Supply

The KHACHIMO DPS-250AB-89G is a 1U form-factor ATX power supply rated at 250W. It uses a combined 20Pin+10Pin connector layout designed for compact server or workstation chassis. The unit targets builders who need reliable power delivery in a shallow rack-mount enclosure. Its 80 PLUS Gold certification and Modern Standby support suit always-on or sleep-heavy workloads.

Replaces proprietary 1U units

This supply upgrades older proprietary 1U PSUs that lack Gold efficiency or Modern Standby compliance. The jump is worth it when the existing unit runs hot, lacks zero-fan operation, or cannot meet current sleep-state requirements. It is not for builds needing higher wattage, redundant modules, or standard 24Pin ATX motherboard connectors.

Fits 1U bays with 20Pin+10Pin wiring

Installation slides the unit into a standard 1U bay and connects the fixed 20Pin+10Pin harness to the matching motherboard headers. What usually goes wrong is a pin-count mismatch on proprietary boards or insufficient cable reach in deeper chassis. Verify the exact header layout before fitting.

Questions about this item

Will the 20Pin+10Pin connector fit a standard ATX motherboard socket?

The unit uses a combined 20Pin+10Pin connector that mates with a 24-pin ATX motherboard socket.

How do I enable the Zero RPM fan mode after installing the PSU?

Zero RPM activates automatically at low and medium loads; no BIOS or software setting is required.

Does the 80 PLUS Gold certification mean the fan bearings will last longer before replacement?

Gold certification reflects electrical efficiency, not fan bearing life; the fan still spins under load and will wear normally over time.
