Power supply for modern standby systems

This 220W ATX unit from KHACHIMO targets compact desktops and upgrades where a low-power, high-efficiency source is required. It suits builders who need reliable wake-from-sleep behaviour without excess capacity.

Gold efficiency and zero-RPM fan change daily use

The 80 PLUS Gold rating reduces waste heat and keeps temperatures lower during typical workloads. Zero RPM mode stops the fan completely at low and medium loads, while resonant LLC topology with DC-to-DC conversion minimises coil whine and supports deeper sleep states.

Straightforward ATX installation with one constraint

Standard ATX mounting and cabling fit most compatible chassis without adapters. The 220W ceiling means systems with discrete graphics cards or many drives will exceed the unit's capacity, so verify total draw before fitting.

Questions about this item

How often will the fan need cleaning or replacement on this 220W ATX unit?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, so dust build-up and bearing wear are reduced compared with units that spin continuously.

What limit appears first when this 220W supply runs at full load for hours?

The 220W maximum output is the hard ceiling; sustained draws above that will trigger protection and shut the unit down.

How loud and hot does this 80 PLUS Gold 220W PSU get during all-day operation?

At low and medium loads the fan stays completely off for silent running, while Gold efficiency keeps waste heat and power draw lower than non-certified designs.
