300 W ATX power supply

The KHACHIMO ACE300F is a 300 W ATX power supply designed for desktop builds that require standard 12 V and 5 V rails. It is suited for office systems, basic home PCs or replacement units where a tested, working supply is needed.

Capacity and headroom

The unit delivers a combined 300 W across its 12 V and 5 V outputs, handling typical low-power processors and integrated graphics. It runs out when a build adds a discrete graphics card, multiple drives or other components that push total draw beyond the 300 W limit.

Questions about this item

Will the 300 W output work with my older ATX motherboard that still uses a 20-pin connector?

The unit follows the ATX form factor and provides 12 V and 5 V rails; a 20-pin motherboard will draw only the pins it needs from the 24-pin connector.

How can I verify the supply is running correctly once installed?

The supplier confirms each unit is test working; after fitting, check that the system powers on stably and the 12 V and 5 V rails stay steady under load.
