Small-form-factor ATX supply

This new KHACHIMO unit is an ATX power supply rated for 5 V and 3 A, delivering up to 15 W of continuous output. It carries 80 PLUS Gold certification for high-efficiency operation and features a resonant LLC topology with DC-to-DC conversion. The design targets builds that need clean, consistent power at very low wattage.

Builders seeking silent, efficient low-power ATX

The supply suits compact or specialised systems where a 15 W 5 V source is sufficient and near-silent running is valued. Its Zero RPM fan mode stops the fan completely at low and medium loads, while Modern Standby compatibility enables extremely fast wake-from-sleep times. Buyers who need higher wattage, multiple voltage rails or standard desktop motherboard connectors should look at other units.

15 W 5 V single-rail output

The deciding specification is the 15 W maximum power delivered on a single 5 V rail at 3 A. This capacity determines whether the unit can meet the load of the intended components. Verify that the target system operates within this limit before purchasing.

Questions about this item

How do I choose the right version of this 5V 3A 15W ATX power supply?

This model is a single 5V 3A 15W ATX unit; there are no alternative capacities or versions listed, so the one listed is the only option to select.

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

It certifies high efficiency at typical loads, which reduces power draw, lowers heat output and allows the fan to run less often for quieter operation.

What does the ATX form factor limit in a modern PC build?

The ATX form factor fits standard ATX cases and motherboards; the 15W output restricts this unit to very low-power systems or specific auxiliary roles rather than mainstream desktop builds.
