KHACHIMO

KHACHIMO 5V 50W Power Supply ACS50B-5

SKU CH-NFMC-XXXN0

An ATX power supply delivering 50 W at 5 V with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby compatibility

  • TypeATX
  • Modern Standby compatibility for rapid wake-from-sleep and improved low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency, reducing power draw, noise and heat
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power and cuts coil whine
  • DC-to-DC design enables more energy-efficient sleep states for lower idle consumption

What this 50W unit powers

The KHACHIMO ACS50B-5 is a 50 watt ATX power supply built for low-draw systems that run on a 5 volt rail. It suits thin clients, embedded appliances or secondary servers where total load stays well within the rated output. Buyers who need more power for discrete graphics or multiple drives should look elsewhere.

Practical limits of the ATX form factor

An ATX chassis slot fixes the physical envelope, so cable routing and airflow follow the case design rather than the supply itself. The 80 PLUS Gold rating guarantees high efficiency at typical loads, yet the 50 watt ceiling means the unit cannot support configurations that exceed this draw even if the connectors fit.

Build quality and daily implications

Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine, while a Zero RPM fan mode stops the fan at low and medium loads for near-silent running. Modern Standby compatibility enables extremely fast wake-from-sleep and better low-load efficiency, so the supply stays quiet and cool during idle periods.

Questions sur cet article

Should I pick the 50 W version or is there a higher-wattage model listed?

The only model shown is the 50 W unit, so choose this one if your build stays within that power budget.

What does the 80 PLUS Gold rating actually deliver in my PC?

It guarantees high efficiency across typical loads, which means lower electricity draw, less heat and quieter fan behaviour.

Does the ATX form factor limit the motherboards or cases I can use?

ATX is the standard desktop size, so it fits any case and motherboard designed for regular ATX power supplies.
