200W ATX PSU for compact builds

This 200 watt ATX power supply targets small-form-factor PCs and office workstations that run modest components. Its 80 PLUS Gold certification means lower wall draw and less heat inside a tight chassis. Modern Standby support gives near-instant wake times for users who leave systems sleeping. It is not for builders who need more power for discrete graphics cards or high-core-count CPUs.

Zero RPM fan and LLC topology

A Zero RPM mode stops the fan completely at low and medium loads, keeping the system near-silent during typical desk work. Resonant LLC topology with DC-to-DC conversion delivers clean voltage regulation and reduces coil whine. The standard ATX footprint fits existing mounting points without adapters. It is not for cases that require SFX or TFX dimensions.

200 watt ceiling and Gold efficiency

The 200 watt limit caps the hardware you can run — no high-end GPUs or heavily overclocked processors. 80 PLUS Gold efficiency peaks around 50 percent load, so very light idle draws sit below the optimal curve. Modern Standby works only with compatible motherboards and operating systems. It is not for systems that may grow beyond this power envelope.

Questions about this item

What does 80 PLUS Gold certification mean for this 200W ATX supply?

The 80 PLUS Gold rating confirms high efficiency operation, which lowers power consumption, reduces noise, and keeps temperatures cooler.

What physical space does this ATX power supply need to fit?

It uses the standard ATX form factor, so it mounts in any case with an ATX PSU bay and uses the usual four screw holes.

How do I install the KHACHIMO 200W unit and what step is often missed?

Secure the supply with four screws, connect the 24-pin ATX and CPU power cables, then verify the Zero RPM fan mode activates at low load for silent running.
