SKU CH-8P5J-69XPY

24 V ATX power supply delivers 250 W with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support

  • TypeATX
  • Modern Standby compatible for near-instant wake from sleep
  • 80 PLUS Gold efficiency reduces power draw and heat
  • Zero RPM fan mode stops the fan at low loads
  • Resonant LLC with DC-to-DC conversion delivers clean, stable power
  • 250 W ATX output at 24 V for compact systems

24V ATX supply for Modern Standby builds

This KHACHIMO ACE-828C unit delivers 250 W from a 24 V DC source in a standard ATX form factor. It is aimed at system integrators and hobbyists assembling compact or industrial PCs that run from a 24 V rail and require fast wake-from-sleep behaviour.

Sustained-load behaviour with Gold efficiency

The 80 PLUS Gold rating means the converter maintains high efficiency across the load range, so waste heat and fan noise stay low during long work sessions. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and suppresses coil whine when the system draws continuous power.

Check your 24 V source and ATX fit before ordering

Verify that your DC source can supply the required current at 24 V and that the chassis accepts a standard ATX power supply. The Zero RPM fan mode stops the fan at low and medium loads, so ensure the case airflow can handle passive cooling during those periods.

Questions about this item

How much noise and heat does the KHACHIMO ACE-828C produce when running all day?

The 80 PLUS Gold certification means high efficiency, so less waste heat and lower fan speeds. Zero RPM mode stops the fan completely at low and medium loads for near-silent operation, and the resonant LLC topology with DC-to-DC conversion reduces coil whine.

What else must I already own for this 24V ATX supply to work?

You need a system that accepts a 24 V DC input and uses an ATX-form-factor power supply. The unit delivers 250 W through standard ATX connectors, so your motherboard and components must be compatible with that voltage and power level.

Will this supply behave well with older hardware I keep in the same build?

Modern Standby compatibility enables faster wake-from-sleep and efficient low-power states that older components can use. The DC-to-DC conversion and resonant LLC topology provide clean, consistent power, which helps stability with legacy parts.
