KHACHIMO
An ATX power module compatible with ABB PM564-R-AC units, delivering 80 PLUS Gold efficiency, Modern Standby support, and a Zero RPM fan mode for silent low-load operation
This new KHACHIMO power module is built as a direct replacement for the ABB PM564-R-AC unit identified by part number 1TNE968900R1220. It uses an ATX form factor and carries 80 PLUS Gold certification for high-efficiency operation. The design includes Modern Standby compatibility for extremely fast wake-from-sleep times and improved low-load efficiency. A resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine.
Technicians servicing ABB equipment requiring the PM564-R-AC specification will find this module matches the required part number. The 80 PLUS Gold rating and Zero RPM fan mode support quiet, efficient operation in compatible industrial or commercial environments. Builders assembling standard desktop PCs should look elsewhere, as this module is engineered specifically for the named ABB power supply application and not for general motherboard compatibility.
The 80 PLUS Gold certification confirms high efficiency operation for lower power consumption, less noise, and cooler temperatures. This efficiency standard is the key specification verifying the module meets the performance level expected for the original ABB power supply. Resonant LLC topology with DC-to-DC conversion further ensures clean power delivery and enables energy efficient sleep states supported by Modern Standby compatibility.

Mount the module using the standard ATX screw pattern, connect the main 24-pin and CPU power cables, then ensure the Zero RPM fan mode engages by verifying low-load efficiency in BIOS.
Periodically clean dust from the fan and heatsinks to maintain the Zero RPM fan mode effectiveness and 80 PLUS Gold efficiency ratings.
The cooling fan will exit Zero RPM mode and spin up once loads exceed the low-to-medium threshold, increasing airflow to maintain stable temperatures.
