ATX power supply for compact builds

The KHACHIMO ACE300F delivers 300 W through a standard ATX form factor. It suits office desktops, small-form-factor PCs and basic home systems that do not need high-wattage headroom. The 80 PLUS Gold certification keeps efficiency high across typical loads. Modern Standby support enables rapid wake-from-sleep behaviour.

Fits standard ATX cases and modern sleep states

The unit slots into any chassis with an ATX power-supply bay and provides the connectors required by current motherboards. Resonant LLC topology with DC-to-DC conversion produces clean rails for stable component operation. Modern Standby compatibility frees the system to enter deeper low-power states without losing responsiveness.

Gold efficiency with semi-passive cooling

At low and medium loads the fan stops completely thanks to Zero RPM Fan Mode, eliminating audible noise. The 80 PLUS Gold rating reduces waste heat, so internal temperatures stay lower during everyday workloads. Resonant LLC design also minimises coil whine for quieter overall operation.

Questions sur cet article

How does the 300 W output behave when the system runs at full load for hours?

The unit delivers a continuous 300 W through its resonant LLC topology with DC-to-DC conversion, keeping voltage stable under sustained demand.

What noise and heat levels should I expect during all-day operation?

80 PLUS Gold efficiency reduces waste heat, and the Zero RPM fan mode stops the fan at low and medium loads for near-silent running.

Which motherboard power connectors must my board already provide for this supply to work?

It uses a standard ATX interface, so your motherboard needs the matching 24-pin main connector and CPU power connector.
