Power Supply for Modern Standby Builds

The KHACHIMO QDI A4800V is a 225W ATX power supply designed for systems that rely on Modern Standby for instant wake and low-power sleep. Its 80 PLUS Gold certification confirms high efficiency across typical loads, reducing wasted energy and operating cost. It suits compact or low-power desktops where a full-size high-wattage unit is unnecessary.

ATX Form Factor with DC-to-DC Design

The unit fits standard ATX mounting points and uses a resonant LLC topology with DC-to-DC conversion to deliver clean, stable voltage rails. This approach supports the deeper sleep states required by Modern Standby hardware while minimising coil whine. Builders gain a reliable power foundation without needing custom cabling or non-standard dimensions.

Quiet Operation Through Zero RPM Mode

A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent running during office work or media playback. The efficient Gold-rated design keeps internal temperatures lower, so the fan spins up less often and at lower speeds when it does engage. This combination suits noise-sensitive environments and long idle periods.

Questions about this item

What happens when the 225 W limit is reached during sustained load?

The unit is rated for 225 W continuous output; exceeding that limit will trigger its protection circuits and shut the supply down to prevent damage.

How loud and hot does the 225 W PSU get when running all day?

An 80 PLUS Gold rating and Zero RPM fan mode keep noise near zero at low and medium loads, while high efficiency reduces waste heat during extended operation.

Which motherboard power connector must my board already have for this ATX unit to work?

A standard 24-pin ATX motherboard connector is required; the supply also provides the usual 4/8-pin CPU and peripheral leads for the rest of the build.
