Compact ATX power supply for low-power builds

The KHACHIMO 220W unit fits standard ATX bays and delivers 220 watts of continuous power. It suits office desktops, thin-client replacements or small-form-factor refreshes that do not require auxiliary GPU connectors. Buyers planning a discrete graphics card or multiple drive arrays should look elsewhere.

80 PLUS Gold efficiency under sustained load

The 80 PLUS Gold rating means the supply maintains high conversion efficiency across a wide load range, reducing waste heat during long work sessions. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight when the system draws steady current for hours. Modern Standby support allows the platform to enter and exit low-power states quickly without losing stability.

Zero RPM fan mode for quiet operation

At low and medium loads the cooling fan stops completely, eliminating audible noise in typical desktop use. When the fan does spin, the LLC resonant design helps suppress coil whine. The combination of high efficiency and semi-passive cooling keeps internal temperatures lower than less efficient units of similar capacity.

Questions about this item

How loud does the 220W unit run when the system is under load all day?

Zero RPM Fan Mode keeps the fan completely off at low and medium loads, and 80 PLUS Gold efficiency reduces waste heat so the fan stays quiet even at higher loads.

What connectors must my motherboard already provide for this ATX supply to work?

It uses the standard 24-pin ATX main connector and a 4-pin or 8-pin CPU power connector that your board supplies.

Will Modern Standby support work with my older motherboard that lacks Modern Standby?

The PSU is Modern Standby compatible, but the fast wake and low-load efficiency benefits only activate when the motherboard and firmware also support Modern Standby.
