Rectangular silver ATX power supply unit with fan grille and cable bundle

KHACHIMO

KHACHIMO 24V 13A ATX 80 PLUS Gold power supply

SKU CH-SS64-4KGZ0

24 V 13 A ATX unit with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology with DC-to-DC conversion

  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • Lower power draw and cooler running via 80 PLUS Gold efficiency
  • Near-silent operation at typical loads with Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC and DC-to-DC design
  • 24 V 13 A ATX output for compatible systems

24V ATX power supply for compatible systems

This 24 volt ATX power supply delivers 13 amps on its primary rail and carries 80 PLUS Gold certification for high efficiency. It targets builders who need a 24V input design rather than a standard mains unit. Buyers requiring a conventional AC-input power supply should look elsewhere.

Sustained load behaviour with Gold efficiency

The 80 PLUS Gold rating means the unit maintains high efficiency across typical workloads, reducing waste heat and keeping internal temperatures lower during extended use. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power delivery under continuous demand. Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation. Modern Standby compatibility supports extremely fast wake-from-sleep times and better low-load efficiency.

Upgrade path for 24V ATX replacements

This unit replaces an existing 24V ATX power supply such as the RTW24-13RN where Gold-rated efficiency, quieter fan behaviour and Modern Standby support are desired. The jump is worthwhile when the current unit lacks 80 PLUS Gold certification, resonant LLC topology or zero-RPM fan operation. Systems that require a different input voltage or form factor cannot use this supply.

Questions about this item

How quiet is the fan during all-day operation?

The Zero RPM Fan Mode stops the fan completely at low and medium loads, and the resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter running.

What motherboard power connectors does the KHACHIMO 24V 13A unit need?

It uses a standard ATX 24-pin motherboard connector and a CPU 4+4-pin connector to deliver power.

Will Modern Standby work with my older motherboard?

Modern Standby compatibility requires motherboard and OS support; the supply enables efficient sleep states, but the feature only activates on platforms that implement Modern Standby.
