300W ATX power supply for compact builds

The KHACHIMO DPS-300AB-24C is a 300W ATX power supply designed for small-form-factor systems and office PCs where space and efficiency matter. It delivers reliable power for everyday workloads, integrated graphics and low-profile expansion cards.

Gold efficiency with zero-RPM fan mode

80 PLUS Gold certification means high efficiency at typical loads, reducing waste heat and electricity use. The Zero RPM fan mode stops the fan completely at low and medium loads for silent operation, while Resonant LLC topology with DC-to-DC conversion minimises coil whine and supports modern sleep states.

Upgrade from basic OEM units when silence matters

This unit replaces low-efficiency OEM power supplies that run loud fans constantly and lack modern standby support. The jump is worth it for builders who need quieter operation, faster wake times and cleaner power delivery in a standard ATX footprint.
