What this product is

The KHACHIMO FM-AT48 is a 48 W ATX power supply built for low-power desktop systems. It carries 80 PLUS Gold certification and uses resonant LLC topology with DC-to-DC conversion to deliver efficient, stable output. Modern Standby compatibility enables rapid wake-from-sleep transitions and improved low-load efficiency. A zero RPM fan mode stops the fan completely at low and medium loads for silent running.

Who this suits

This unit suits builders assembling compact office PCs, thin clients or embedded systems that draw minimal power. It also fits users who prioritise quiet operation and fast sleep recovery in a small-form-factor chassis. Systems requiring substantially more output or operation on voltages other than 220 V will need a different power supply.

The deciding specification

The 48 W rated output is the single figure that determines whether this unit can support a given build. Verify the total continuous power draw of every component against this limit before purchasing.

Questions about this item

What cables and connectors come with the KHACHIMO FM-AT48 and what must I source separately?

The unit ships with its fixed ATX power cables; any specialised adapters or extension cables for non-standard boards are not included and must be purchased separately.

Which capacity of the FM-AT48 should I choose for a low-power system?

The only capacity offered is 48 W, so select this model when your total system draw stays within that limit.

What does the 80 PLUS Gold rating mean for daily operation?

It guarantees at least 80 % efficiency at typical loads, reducing waste heat and allowing the fan to stay off longer under light demand.
