220W ATX Power Supply for Modern Standby Systems

This 220W ATX unit targets compact or low-power builds that require Modern Standby compatibility for rapid wake-from-sleep. Its 80 PLUS Gold certification and resonant LLC topology with DC-to-DC conversion deliver efficient, clean power for everyday computing tasks.

220 Watt Capacity Handles Efficient Low-Load

The 220 watt limit suits office PCs, thin clients or embedded systems with modest CPU and GPU demands. It runs out of headroom quickly if a discrete graphics card or high-core-count processor is added, so buyers needing more power must select a higher-wattage model.

Zero RPM Fan Mode Enables Near-Silent Idle Operation

At low and medium loads the cooling fan stops completely, removing audible noise during typical desktop use. The Gold-rated efficiency and LLC design further reduce heat and coil whine, supporting the deeper sleep states that Modern Standby requires.

Questions about this item

Will this 220 W ATX unit power an older motherboard that still uses a 24-pin main connector and a 4-pin CPU plug?

Yes — it is a standard ATX supply with a 24-pin main cable and a 4+4-pin CPU cable, so it fits legacy boards that use the 24-pin and 4-pin combination.

How can I verify the Zero RPM fan mode is actually active after I install the PSU?

Under light or medium load the fan stops completely; you can confirm it by listening for silence and watching the fan blades remain still while the system is idle.

Which cables come attached to the unit and what must I purchase separately?

All cables are fixed — 24-pin ATX, 4+4-pin CPU, and peripheral leads — so no modular cables need to be bought separately.
