300 W ATX power supply for office PCs

The KHACHIMO 300 W ATX unit fits small-form-factor desktops and office workstations that need a compact, efficient supply. It delivers the standard ATX form factor with Modern Standby support for rapid wake-from-sleep. Builders seeking higher wattage for discrete graphics should choose a larger model.

80 PLUS Gold certified efficiency

This supply meets the 80 PLUS Gold standard, meaning it maintains high efficiency across typical loads. The certification guarantees lower electricity draw, reduced heat output and quieter operation compared with non-certified units of the same class.

Zero RPM fan mode and LLC topology

At low and medium loads the fan stops completely for near-silent running. A resonant LLC topology with DC-to-DC conversion supplies clean power, cuts coil whine and enables deeper, more efficient sleep states.

Questions about this item

What does the 300W rating mean for a typical desktop build?

The 300W rating is the maximum continuous power this ATX unit can deliver. It suits office PCs or basic home systems with integrated graphics, but leaves little headroom for a discrete GPU.

How does the 80 PLUS Gold certification affect daily use?

80 PLUS Gold means the supply runs at high efficiency across typical loads, so it draws less mains power, generates less heat and helps keep fan noise low.

Will the standard ATX form factor fit my case?

Yes, the unit follows the ATX form factor, so it mounts in any case designed for a standard ATX power supply.
