KHACHIMO 100W ATX Power Supply

The KHACHIMO PSC100-D-1 is a 100W ATX power supply built for compact or low-power desktop builds. It suits small-form-factor systems, embedded appliances, or secondary machines where modest output and high efficiency matter more than raw wattage. Builders needing multi-GPU headroom or high-end CPU overclocking should look elsewhere.

80 PLUS Gold Thermals and Acoustics

An 80 PLUS Gold rating keeps efficiency high across typical loads, reducing waste heat and overall power draw. Resonant LLC topology with DC-to-DC conversion delivers clean voltage regulation and lowers coil whine. The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation.

Modern Standby and Quiet Operation

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improves low-load efficiency for always-connected workflows. The combination of Zero RPM mode and resonant topology cuts audible noise during idle and light tasks. No extra cables, adapters, or software utilities are mentioned in the supplied data.

Questions about this item

How do I install this ATX power supply and which step is often missed?

Mount the unit in the case with four screws, plug the 24-pin ATX and CPU power cables into the motherboard, then connect the remaining leads to drives and graphics cards; the step most often missed is seating the 4- or 8-pin CPU auxiliary connector near the socket.

What maintenance or replacement will this power supply need later?

The 80 PLUS Gold certified unit uses a Zero RPM fan mode that stops the fan at low and medium loads, reducing bearing wear; the main item that may eventually need replacement is the cooling fan itself after years of continuous operation.

What limit appears first under sustained use?

At continuous loads approaching the 100W rating the cooling fan will spin up from its Zero RPM state, so audible fan noise becomes the first noticeable limit before thermal protection activates.
