Compact 1U ATX power supply for thin systems

The KHACHIMO ST-150FUB-05E is a 150W ATX unit built to the 1U Flex form factor. It targets small-chassis builds such as thin clients, mini PCs or embedded appliances where vertical space is at a premium. The new condition means it arrives with full factory specifications intact.

Sustained load behaviour with Gold efficiency

Rated for 150W continuous output, the supply holds its 80 PLUS Gold efficiency across the load curve, keeping waste heat and fan speed low during long sessions. Resonant LLC topology with DC-to-DC conversion delivers stable rails and supports modern sleep states without voltage droop. The fan remains off at low and medium loads for silent running.

Build notes and connector implications

The 1U height lets the unit slide into rack-mount or slim desktop enclosures without blocking adjacent slots. Modern Standby compatibility enables near-instant wake from sleep, useful for always-on kiosks or digital signage. Zero RPM mode removes acoustic distraction in quiet offices, while the LLC design minimises coil whine under varying loads.

Questions about this item

How loud is the 150W unit after hours of continuous operation?

The Zero RPM fan mode stops the fan completely at low and medium loads, so the PSU runs silently for long periods; 80 PLUS Gold efficiency also keeps waste heat low.

Which cables must already be in the case for the ATX supply to power the build?

A standard ATX 24-pin motherboard connector and a 4/8-pin CPU power connector are required; the unit follows the regular ATX pin-out so existing cables fit.

Will the 80 PLUS Gold platform wake quickly from sleep on an older motherboard?

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency even with legacy boards that support the sleep state.
