  • TypeATX
  • Modern Standby support for extremely fast wake-from-sleep
  • 80 PLUS Gold efficiency reduces power draw and heat

ENHANCE 1U 220W Replacement Unit

This new KHACHIMO power supply replaces the ENP-2322B model used in 1U ENHANCE chassis. It delivers 220 watts through a standard ATX connector layout designed for that specific form factor. The unit arrives in new condition ready for immediate installation.

Suited for 1U server maintenance.

Technicians servicing the matching ENHANCE platform will find the correct pin-out and physical dimensions. Builders assembling standard tower PCs or needing higher wattage for discrete graphics should look at other form factors because this unit is purpose-built for the original 1U enclosure.

80 PLUS Gold efficiency with Zero RPM fan mode

The supply meets 80 PLUS Gold certification for lower power draw and cooler running. A Zero RPM mode stops the fan completely at low and medium loads, while resonant LLC topology with DC-to-DC conversion reduces coil whine and supports Modern Standby sleep states.

Questions about this item

What motherboard power connector does the 220 W unit need to function?

It uses a standard ATX connector, so any motherboard with a 24-pin ATX socket will power on.

Will the Zero RPM fan mode still engage if I keep an older graphics card that draws constant power?

The fan stays off at low and medium loads; a legacy card that idles at higher draw may keep the fan spinning.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

The PSU runs cooler and quieter under typical loads, and the fan remains off during light use, indicating high-efficiency operation.
