KHACHIMO

KHACHIMO 280W ATX power supply 24V 48V

SKU CH-RS2T-DJYEG

ATX power supply delivering 24 V and 48 V rails at 280 W with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and LLC resonant topology for clean, quiet power

  • TypeATX
  • Modern Standby support enables near-instant wake from sleep
  • 80 PLUS Gold efficiency reduces power draw and heat output
  • Zero RPM mode stops the fan at low loads for silent running
  • Resonant LLC with DC-to-DC delivers clean power and cuts coil whine
  • Dual 24V and 48V rails suit specialised ATX configurations

ATX 280W dual-voltage supply

This KHACHIMO ATX power supply delivers 280W across 24V and 48V rails for specialised systems such as the Mindong platform. It targets builders who need a compact, efficient unit for industrial or embedded workloads rather than mainstream desktop gaming rigs.

80 PLUS Gold headroom at 280W

The 80 PLUS Gold certification keeps efficiency high across typical loads, reducing heat and fan noise while the resonant LLC topology with DC-to-DC conversion provides stable voltage regulation. Continuous output is rated at 280W, so sustained draws beyond that level will exceed the unit's capacity.

Zero RPM fan and Modern Standby ready

A zero RPM fan mode stops the fan completely at low and medium loads for near-silent running, while Modern Standby compatibility enables extremely fast wake-from-sleep transitions. The ATX form factor fits standard chassis mounting points, though the dual-voltage design limits use to systems specifically requiring 24V and 48V rails.

Questions about this item

Will the ATX form factor and 280W output fit the case and power the components of an older PC build?

The ATX form factor matches standard cases, and the 280W capacity with 80 PLUS Gold efficiency delivers reliable power for older systems.

How can I confirm the 80 PLUS Gold efficiency and Zero RPM fan mode are active after installation?

The fan stays off at low and medium loads, and the 80 PLUS Gold rating means high efficiency, lower consumption and cooler operation.

Does the box include the ATX power cables needed for a 24V and 48V setup, or must I buy them separately?

The unit is an ATX switching power supply rated for 24V and 48V outputs; standard ATX cables are integrated for direct connection.
