SKU CH-ZM9G-76R9A

A 36 V ATX unit delivering 18 A for 650 W output with 80 PLUS Gold efficiency, zero-RPM fan mode and resonant LLC topology for quiet, low-load operation

  • TypeATX
  • Faster wake-from-sleep with Modern Standby compatibility
  • Lower power draw and cooler running via 80 PLUS Gold efficiency
  • Near-silent operation at low loads with Zero RPM fan mode
  • Clean, stable power delivery using resonant LLC and DC-to-DC topology
  • 650W ATX supply delivering 18A on the 36V rail

Power supply for SHP650PS systems

The KHACHIMO 36V 18A unit delivers 650W through an ATX form factor. It is built as a direct replacement for the SHP650PS and SHP650PS36-EF models used in compatible workstations. The 80 PLUS Gold certification confirms high efficiency across typical loads.

Standard ATX fit with semi-passive cooling

Installation follows normal ATX mounting points and connector routing. The Zero RPM fan mode keeps the unit silent at low and medium loads, so cable placement near the fan grille is less critical. Resonant LLC topology with DC-to-DC conversion reduces coil whine, a common annoyance in similar OEM replacements.

36V 18A output defines compatibility

The single rail provides 36V at 18A, which determines whether the supply matches the original specification. Systems expecting a different voltage or current rating will not operate correctly with this unit.
