KHACHIMO ATX Gold Power Supply

This KHACHIMO ATX power supply delivers 80 PLUS Gold certified efficiency for desktop PCs and workstations. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The unit suits builders who value quiet operation and stable power delivery across varying workloads.

Upgrade from lower-efficiency units

Replacing a standard Bronze or unrated PSU with this Gold-rated model reduces power consumption, noise, and operating temperatures. The resonant LLC topology with DC-to-DC conversion provides cleaner power and reduces coil whine. The jump is worthwhile when building a system that spends long periods at idle or light load.

Handles typical desktop loads

Zero RPM fan mode keeps the unit silent at low and medium loads while maintaining cooler temperatures. The topology supports more energy-efficient sleep states for modern operating systems. Systems drawing sustained heavy loads near the unit's maximum rating will engage active cooling and lose the silent advantage.

  • Lower power draw and cooler temps via 80 PLUS Gold efficiency
  • Near-silent operation with Zero RPM fan mode at low loads

Questions about this item

What ATX case clearance does the KHACHIMO AMS200 AMS1000 DF700-RKH power supply require?

It follows the standard ATX form factor, so any case with an ATX PSU bay will accept it.

How is the unit installed and what step do builders often miss?

Mount the supply with the four rear screws, connect the 24-pin ATX, CPU and GPU cables, then enable Modern Standby in the BIOS so the fast wake and low-load efficiency features actually work.

What maintenance will the power supply need over time?

The Zero RPM fan stops at low loads, so dust builds up more slowly; vacuum the intake grille once a year and the fan bearings should last the life of the unit.
