KHACHIMO NEC AIO i5 HM55 HM65 HM75 120W Power Supply

SKU CH-0NEX-TNZQ5

120 W ATX power supply for NEC AIO i5 HM55 HM65 HM75, 80 PLUS Gold with Zero RPM fan mode

  • TypeATX
  • Modern Standby support gives extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower consumption, less noise and cooler temperatures
  • Zero RPM fan mode stops the cooling 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
  • 120 W output matches NEC AIO i5 HM55 HM65 HM75 power requirements

Compatible AIO Power Unit

This 120 W ATX power supply is built as a direct replacement for NEC all-in-one systems carrying the i5 HM55, HM65 or HM75 designations. It carries the DPS-120TB A and MSPSU120N-DMA part identifiers and is supplied in new condition.

Suitable for Like-for-Like Repairs

The unit matches the original connector layout and power rating for the listed NEC AIO models, so technicians can swap it without adapter cables or case modifications. Builders working on standard desktop chassis or on any other AIO platform should look elsewhere because the form factor and pin-out are specific to these machines.

Steady Output with Silent Low-Load Operation

An 80 PLUS Gold rating and resonant LLC topology with DC-to-DC conversion keep voltage regulation tight during extended workloads while reducing coil whine. Modern Standby support allows rapid wake from sleep, and the zero-RPM fan mode stops the fan completely at low and medium loads for near-silent running.

Questions about this item

What motherboard power connector does the KHACHIMO 120W PSU require?

The unit uses a standard ATX connector, so your motherboard must provide a matching 24-pin ATX socket.

Will the 120W output support my existing HM55, HM65 or HM75 chipset AIO?

Yes, the 120 watt rating matches the original DPS-120TB A specification for those NEC i5 all-in-one models.

How do I confirm the PSU is running correctly after installation?

Check that the system powers on, the 80 PLUS Gold efficiency is active, and the fan stays off under light load thanks to Zero RPM mode.
