KHACHIMO WM-2 5V15A 12V6A 24V2A power supply

SKU CH-1F4X-1CF95

An ATX power supply delivering 5V at 15A, 12V at 6A and 24V at 2A with 80 PLUS Gold efficiency, Modern Standby support and a zero-RPM fan mode for silent low-load operation

  • TypeATX
  • Modern Standby compatible for rapid wake-from-sleep
  • 80 PLUS Gold certified for high efficiency and cooler running
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power
  • ATX form factor fits standard desktop builds

Modern Standby ATX power supply

The KHACHIMO WM-2 is an ATX power supply built for systems that use Modern Standby sleep states. It delivers 5 V, 12 V and 24 V rails to support a wide range of components. The unit is suited for builders who need fast wake-from-sleep response and efficient low-load operation. It is not for buyers who require higher total wattage than the rated rails provide.

80 PLUS Gold with Zero RPM mode

Gold certification means high efficiency across typical loads, reducing power draw and heat output. The Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion further lowers coil whine and supports deeper sleep states. This design keeps thermals and noise low in everyday use.

Multi-rail output for mixed voltage needs

The supply provides 5 V at 15 A, 12 V at 6 A and 24 V at 2 A simultaneously. This specific rail distribution decides whether the unit matches a build that needs all three voltages at those currents. Builds that demand more 12 V current or lack a 24 V load should look elsewhere.

Questions about this item

How do I install this ATX power supply in my case and what step is often missed?

Mount the ATX unit with four screws, connect the 24-pin motherboard cable and the CPU power cable, then route cables behind the motherboard tray; the step often missed is plugging in the CPU power connector near the socket.

What maintenance or replacement will this unit need over time?

The fan bearings may eventually wear out and the electrolytic capacitors will age; plan to replace the whole unit after several years of continuous use rather than servicing individual parts.

What limit appears first when this supply runs at sustained load?

The 12 V rail is rated at 6 A; drawing more current than this will trigger over-current protection before thermal limits are reached.
