Compact 1U FlexATX power supply

This KHACHIMO unit delivers 200 W of continuous power in a 1U FlexATX form factor, designed for slim desktop, POS and industrial chassis where space is at a premium. It carries 80 PLUS Gold certification and uses resonant LLC topology with DC-to-DC conversion to maintain tight voltage regulation and low ripple across the load range. Modern Standby compatibility ensures rapid wake times and improved efficiency at very low loads.

Suited for small-form-factor builds needing quiet.

The Zero RPM fan mode stops the fan completely at low and medium loads, making the supply near-silent in typical office or kiosk workloads. Builders who require more than 200 W for discrete graphics cards, multiple storage arrays or high-core-count CPUs should look at higher-wattage designs. Systems that need a standard ATX or SFX footprint will not fit this 1U chassis.

200 W maximum output decides fit

The single figure that determines suitability is the 200 W rated capacity; if the total system draw under full load stays below this ceiling the supply will operate within its certified efficiency band. Exceeding that limit risks protection trips or instability, so confirm the complete hardware power budget before selecting this model.

Questions about this item

What clearance does this 1U FlexATX unit need inside a small chassis?

It is a 1U FlexATX form-factor supply rated at 200 W, designed to slide into slim enclosures that accept that exact size.

Which cables must be connected during installation, and where is the common mistake?

Attach the 24-pin ATX and 4/8-pin CPU connectors; the step often missed is enabling Modern Standby in the motherboard BIOS so the fast wake and low-load efficiency features activate.

What component will likely need attention after extended use?

The cooling fan, which runs in Zero RPM mode at low and medium loads, is the only moving part and the item most likely to require cleaning or replacement over time.
