ATX power supply for modern standby systems

The KHACHIMO DL320G5 delivers 420 W of continuous power through an ATX form factor. It targets desktop builds that require fast wake-from-sleep response and high efficiency at low loads. The unit carries 80 PLUS Gold certification and supports modern standby sleep states for reduced idle consumption.

Sustained-load behaviour and thermal profile

Under continuous demand the resonant LLC topology with DC-to-DC conversion maintains stable voltage regulation and limits coil whine. The 80 PLUS Gold rating ensures high efficiency across the load range, which reduces waste heat and keeps internal temperatures lower during extended operation. At low and medium loads the Zero RPM fan mode stops the fan completely for silent running.

Replacement scope and upgrade value

This unit replaces an older ATX supply that lacks modern standby support or Gold-level efficiency. The jump is worthwhile when a system needs quicker sleep recovery, quieter low-load acoustics, or cleaner power delivery for energy-efficient sleep states. It is not suited for builds requiring more than 420 W of rated output.

Questions about this item

How loud and hot does the DL320G5 get when running continuously?

The 80 PLUS Gold certification and resonant LLC topology with DC-to-DC conversion deliver high efficiency, lower heat output and reduced coil whine. At low and medium loads the Zero RPM fan mode stops the fan entirely for near-silent operation.

What must my system provide for this 420W ATX unit to power on?

A standard ATX motherboard with a 24-pin main power socket and matching CPU power connector, plus a case that accepts ATX-form-factor power supplies.

Will the Modern Standby support work with my older motherboard?

Modern Standby compatibility enables extremely fast wake-from-sleep and better low-load efficiency, but the feature requires a motherboard and operating system that also support Modern Standby.
