KHACHIMO

KHACHIMO 200W ATX Power Supply 8Pin Gold

SKU CH-M3CJ-8PHM8

200 W ATX power supply with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology for clean, quiet power

  • TypeATX
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode keeps the system silent at low loads
  • Modern Standby support gives near-instant wake from sleep
  • Resonant LLC with DC-to-DC conversion delivers clean, stable power
  • ATX form factor fits standard desktop chassis

Purpose & Audience

This 200 W ATX power supply is built for compact desktop systems such as the B320, B325r, B520 and B540 platforms. It serves builders who need a small, efficient unit that supports Modern Standby for instant wake-from-sleep in office or home PCs.

Upgrade Context

The unit replaces older 200 W designs that lack 80 PLUS Gold certification and Zero RPM fan behaviour. The jump is worthwhile when moving from a basic Bronze or unrated supply to gain higher efficiency, quieter low-load operation and support for deeper sleep states.

Build Integration

An 8-pin connector delivers CPU power while the resonant LLC topology with DC-to-DC conversion provides stable rails for modern components. The fan stays off at low and medium loads, freeing acoustic headroom in small chassis where airflow is limited.

  • Zero RPM fan mode keeps the system silent at low loads

Questions about this item

What form factor and connector does this power supply use for installation?

The unit follows the ATX form factor and includes an 8-pin connector for the CPU power socket, fitting standard ATX cases and motherboards.

How do you install this PSU and what step is often missed?

Mount the PSU in the case with four screws, connect the 20+4 pin ATX and 8-pin CPU cables, then verify the 8-pin CPU connector is fully seated — many builders leave it loose.

Which part of this power supply will need attention or replacement over time?

The cooling fan is the only moving component; if bearing noise appears after extended use, the fan can be replaced while the rest of the unit remains solid.
