Compact 100W ATX PSU

The KHACHIMO SNP-B109-W is a 100 watt ATX power supply built for small-form-factor PCs and low-power appliances. Its modest output suits embedded systems, thin clients or secondary rigs where a full-size unit would be wasted space. Builders needing multi-GPU headroom or high-wattage overclocking should look elsewhere.

Gold efficiency with silent low-load running

An 80 PLUS Gold rating keeps waste heat and power draw low across the load range. At light and medium workloads the Zero RPM fan mode stops the fan completely, removing audible noise. Resonant LLC topology with DC-to-DC conversion delivers steady voltage and reduces coil whine for quieter operation overall.

Modern Standby support for instant wake

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improves low-load efficiency. The bundled DC-to-DC design allows deeper, more energy-efficient sleep states without extra configuration. No additional software or cables are mentioned in the specifications.

Questions about this item

How do I install the ATX power supply and what step is often missed?

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

What maintenance will this 100W unit need over time?

The Zero RPM fan mode keeps the fan off at low loads, reducing dust build-up; clean the intake vents once a year and the fan bearings should last the life of the supply.

Which limit appears first during sustained high load on this Gold-rated supply?

The 100W maximum output is reached before thermal or efficiency limits, so the unit will shut down if the system tries to draw more than its rated capacity.
