15W ATX Gold unit

The KHACHIMO LFA15F is a 15W ATX power supply certified to 80 PLUS Gold efficiency. It targets compact or low-power builds that require an ATX form factor but draw very little current. Modern Standby compatibility ensures rapid wake-from-sleep transitions and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine.

ATX fit and Modern Standby support

Verify that your chassis accepts a standard ATX power supply and that your motherboard and operating system support Modern Standby to benefit from the fast wake capability. The 15W maximum output limits this unit to systems with extremely low power demands. Ensure the available connectors match your components before ordering.

Zero RPM mode and quiet topology

A Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. The resonant LLC design with DC-to-DC conversion further minimises coil whine and enables deeper, more energy-efficient sleep states. These features combine to reduce audible noise without adding extra accessories.

Questions about this item

What comes in the box with the LFA15F and do I need to buy cables separately?

The unit ships as a 15 W ATX power supply with fixed output cables attached; no modular cables are included or required.

Should I choose the LFA15F-5-SNJ1, LFA15F-5-SN or LFA15F-5 version?

All three designations refer to the same 15 W 5 V 3 A ATX model; pick whichever SKU your supplier lists.

What does the 80 PLUS Gold rating mean for daily use of this 15 W unit?

It certifies high efficiency across the load range, so the PSU wastes less energy, produces less heat and lets the zero-RPM fan stay off longer.
