SKU CH-R3D1-9KA9E

A 75 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for silent, low-power sleep states

  • TypeATX
  • Modern Standby support delivers extremely fast wake-from-sleep times
  • 80 PLUS Gold certification ensures 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
  • ATX form factor supplies 75 W of reliable power for compatible systems

Compact ATX Power Supply

The KHACHIMO 75W ATX unit delivers 75 watts of continuous power for low-draw desktop builds and embedded systems. It targets integrators who need a small, efficient supply for thin clients, digital-signage players or fanless workstations. Modern Standby compatibility ensures rapid wake-from-sleep transitions in supported operating systems.

Thermals Noise And Efficiency

80 PLUS Gold certification confirms high conversion efficiency across the load range, reducing waste heat and overall power draw. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion further limits coil whine and supports deeper sleep states.

Build Quality And Connectors

Resonant LLC topology with DC-to-DC conversion provides clean, consistent power delivery to sensitive components. Standard ATX mounting points allow direct installation in compatible chassis without adapters. The 12 volt rail design suits modern single-rail component layouts. Builders needing higher wattage or additional PCIe connectors should select a larger unit.

Questions about this item

How do I install the ATX power supply and what step is often missed?

Mount the unit in the case using the standard ATX screw pattern, connect the 24-pin motherboard cable and the 12 V CPU cable, then ensure the AC power cord is fully seated and the rear power switch is set to the on position.

What maintenance or replacement will this 75 W unit need later?

The Zero RPM fan mode reduces wear, but dust should be cleared from the intake vents periodically; if the fan bearings eventually become noisy, the entire power supply is replaced as a single field-replaceable unit.

What limit appears first under sustained load on this 80 PLUS Gold supply?

Continuous output is capped at 75 W, so the over-power protection circuit will trigger before thermal limits if the connected components draw more than the rated capacity.
