374 W ATX Power Supply

The KHACHIMO L221 is a 374 W ATX unit built for systems that need Modern Standby support and 80 PLUS Gold efficiency. It suits office PCs, compact workstations and quiet home builds where low power draw and fast sleep recovery matter.

Fits standard ATX layouts

The supply uses a resonant LLC topology with DC-to-DC conversion to deliver clean power to modern motherboards and graphics cards. Its Modern Standby compatibility enables deeper sleep states, freeing the platform from legacy power constraints while maintaining stable rails for all connected components.

Gold efficiency with zero-RPM mode

At low and medium loads the fan stops completely, removing audible noise from the system. The 80 PLUS Gold rating keeps waste heat and power consumption low, so temperatures stay modest even under sustained operation without demanding extra case airflow.

Questions about this item

How does the 374 W rating hold up when the system runs at full load for hours?

The 374 W maximum output is continuous; the 80 PLUS Gold design keeps efficiency high so the unit stays within its thermal limits during sustained full-load operation.

What happens to fan noise and heat output when this power supply runs all day under typical loads?

Zero RPM mode stops the fan completely at low and medium loads, giving near-silent operation and lower temperatures, while the LLC resonant topology further reduces coil whine.

Which motherboard power connectors must already be present for this ATX unit to work?

A standard 24-pin ATX main connector and the matching 4-pin or 8-pin CPU power connector are required on the motherboard for this supply to function.
