Compact 1U ATX Power Supply

The KHACHIMO FLEX Small unit delivers a rated 180W output in a 1U form factor designed for space-constrained builds. It targets system integrators and enthusiasts assembling low-profile desktops or compact servers that require standard ATX connectivity. This power supply is not suited for buyers who need higher wattage for discrete graphics cards or multi-drive arrays.

Thermals and Efficiency

An 80 PLUS Gold certification confirms high efficiency across typical loads, reducing waste heat and overall power draw. The Zero RPM fan mode stops the cooling fan completely at low and medium loads, enabling near-silent operation during idle or light tasks. Resonant LLC topology with DC-to-DC conversion further minimises coil whine and supports cooler running temperatures.

Modern Standby and Power Quality

Modern Standby compatibility allows extremely fast wake-from-sleep transitions while maintaining low-load efficiency. The DC-to-DC conversion architecture delivers clean, consistent voltage regulation to sensitive components. These features benefit users who prioritise quick system responsiveness and stable power delivery in always-on or frequently suspended environments.

Questions about this item

How do I mount this 1U unit and connect the ATX cables without blocking airflow?

Install the power supply so its fan faces the chassis exhaust path, then route the 24-pin ATX, 4-pin CPU and peripheral cables through the designated grommets — the step most builders miss is leaving a clear gap behind the fan intake so the Zero RPM mode can actually stay silent at low load.

What part will need attention first after long-term use?

The cooling fan is the only moving component; its bearings will eventually wear, but the Zero RPM mode reduces run-time at low and medium loads, extending the interval before a fan replacement is required.

At what load does the fan spin up and become the limiting factor for noise?

The Zero RPM mode keeps the fan stopped at low and medium loads, so audible noise only appears once the load rises high enough to trigger active cooling — the 180 W rating marks the ceiling where sustained output forces the fan to run continuously.
