KHACHIMO 225W ATX Power Supply 80 PLUS Gold

SKU CH-KDE1-RYVZ4

An 80 PLUS Gold certified 225W ATX unit with Modern Standby support, Zero RPM fan mode and resonant LLC plus DC-to-DC topology for quiet, efficient power delivery

  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops at low loads for silent running
  • Resonant LLC and DC-to-DC deliver clean, stable power
  • 225 W ATX unit fits ZWD225PAF-0524/J replacements

Compatible Replacement Unit

This 225W ATX power supply is built to match the ZWD225PAF-0524J form factor used in specific TDK-Lambda platforms. It delivers 5V at 5A and 24V at 9A through a resonant LLC topology with DC-to-DC conversion. The design targets system integrators and technicians servicing compatible industrial or embedded hardware.

Connector And Voltage Verification

Before ordering, confirm that the target chassis accepts the exact pin-out and mounting pattern of the original ZWD225PAF-0524J unit. Check that the 5V and 24V rail ratings align with the system's load requirements. Ensure the physical dimensions and screw locations correspond to the existing cut-out.

Sustained Load Behaviour

The 80 PLUS Gold certification indicates high efficiency during continuous operation, reducing waste heat and supporting cooler internal temperatures. Zero RPM fan mode keeps the unit silent at low and medium loads, while the resonant topology maintains stable output under prolonged demand. Modern Standby compatibility allows rapid wake cycles without voltage droop.
