220 W ATX Power Supply

The KHACHIMO unit delivers 220 W of continuous ATX power with 80 PLUS Gold efficiency. Resonant LLC topology and DC-to-DC conversion provide clean, stable output while enabling modern standby sleep states. A zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation.

Compact Builds and Modern Standby Systems

This supply suits small form factor PCs or upgrades that require a 220 W ATX source with high efficiency and quiet low-load behaviour. It is not for systems needing higher wattage, multi-GPU configurations, or builders who require modular cabling for custom cable routing.

220 W Continuous Capacity

The 220 W rating handles mainstream CPUs, integrated graphics, and single mid-range discrete cards with headroom for peripherals and storage. It runs out when total system draw approaches the rated limit, such as with high-end GPUs, overclocked processors, or multiple drive arrays that exceed the available power budget.

Questions about this item

Does my motherboard need a specific ATX power connector for this 220W unit?

Yes, it requires a standard ATX 24-pin main connector plus the appropriate CPU and peripheral cables for your build.

Will the Zero RPM Fan Mode stay silent when paired with an older, lower-efficiency graphics card?

The fan remains off at low and medium loads regardless of the graphics card, so older GPUs will not force the fan to spin under light use.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Monitor system power draw at the wall under typical load; the unit should maintain Gold-level efficiency, reducing consumption and heat versus lower-rated supplies.
