KHACHIMO power supply for ASTEC 73-551-0015 ATX 80 PLUS Gold

SKU CH-QJVF-BG42S

An ATX power supply for ASTEC 73-551-0015 with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology for clean, quiet power

  • TypeATX
  • Modern Standby compatible for faster wake times and better low-load efficiency
  • 80 PLUS Gold certified for lower power consumption, less noise and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • Designed for ASTEC 73-551-0015 as a direct ATX replacement

Compatible replacement for ASTEC 73-551-0015

This KHACHIMO ATX power supply is built as a direct replacement for the ASTEC 73-551-0015 unit. It suits system integrators and technicians who need a modern, efficient PSU that fits the original mounting points and connector layout.

80 PLUS Gold efficiency with Zero RPM fan mode

Gold certification means high efficiency across typical loads, reducing waste heat and lowering overall power draw. The Zero RPM mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion minimises coil whine and supports deeper sleep states.

Modern Standby support for faster wake times

The unit is Modern Standby compatible, enabling extremely fast wake-from-sleep and better low-load efficiency. It is not intended for builds that require higher wattage than the original ASTEC design or for systems needing additional PCIe power connectors not present on this model.

Questions about this item

How is the ATX power supply installed and what step is often missed?

Mount the unit in the case with four screws, connect the 24-pin ATX, CPU and peripheral cables, then enable Modern Standby in the BIOS so the fast wake-from-sleep feature actually works.

What maintenance or replacement will this unit need later?

The Zero RPM fan mode keeps the fan off at low loads, reducing wear, but the fan bearings will eventually require cleaning or replacement after years of continuous operation.

What limit appears first under sustained heavy load?

The 80 PLUS Gold efficiency rating means waste heat rises as load increases, so thermal protection will throttle output before the Resonant LLC topology reaches its electrical limits.
