SKU CH-E17A-VJS9R

An ATX power supply delivering 300 watts with 80 PLUS Gold efficiency, zero-RPM fan mode for silent low-load operation and Modern Standby support for fast wake times

  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • High efficiency reduces power draw and heat with 80 PLUS Gold
  • Silent operation at low loads via Zero RPM fan mode
  • Clean, stable power delivery through LLC resonant topology with DC-to-DC conversion
  • Cooler, quieter system thanks to high efficiency and fan-off design

ACE300F 300W ATX Gold PSU

The KHACHIMO ACE300F is a 300W ATX power supply certified to 80 PLUS Gold efficiency. It uses a resonant LLC topology with DC-to-DC conversion to deliver stable voltage rails and reduce coil whine during operation.

Best for low-power office builds

This unit suits compact desktop PCs or basic workstations where 300W covers the entire system draw and Modern Standby fast wake is valued. Builders planning a discrete graphics card, multiple storage drives or sustained heavy loads should look at higher-wattage models instead.

Standard ATX fit with quiet fan

Installation follows the usual ATX mounting pattern and connector layout used in most chassis. The Zero RPM fan mode keeps the unit silent at low and medium loads, though the fan will spin up under heavier demand and airflow direction depends on case design.

Perguntas sobre este artigo

Does the ACE300F fit a standard ATX case?

Yes, it is an ATX-type power supply designed for standard ATX chassis.

Will the Zero RPM fan mode stay off with older components that draw little power at idle?

At low and medium loads the cooling fan switches off entirely, so older parts that keep draw low will keep the fan stopped.

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

The unit meets 80 PLUS Gold certification, delivering high efficiency operation for lower power consumption, less noise, and cooler temperatures.
