KHACHIMO 300W ATX Power Supply

This KHACHIMO ATX power supply delivers 300 watts of continuous power for desktop systems that require a standard form-factor unit. It is suited to office workstations, home PCs and light content-creation builds where peak draw stays well within the rated output.

Efficiency and load headroom

The unit carries 80 PLUS Gold certification, so it maintains high efficiency across typical loads, reducing waste heat and fan activity. At 300 watts it comfortably powers mid-range CPUs and single GPUs, but it will run out of headroom for multi-GPU arrays or heavily overclocked configurations.

Build features and daily use

A resonant LLC topology with DC-to-DC conversion supplies clean voltage rails and minimises coil whine, while the Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and better low-load efficiency.

Questions about this item

Will the KHACHIMO DS-9124 9134 9148 300W power supply fit my existing ATX case?

This unit follows the ATX form factor, so it mounts in standard ATX cases and aligns with the usual screw-hole pattern and rear cut-out.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

At typical loads the PSU should run cool and the fan often stays off thanks to Zero RPM Fan Mode; you can also verify the 80 PLUS Gold badge on the unit's label.

Which cables come attached to the KHACHIMO DS-9124 9134 9148 300W and what must I source separately?

The supply ships with its fixed ATX cable set; any specialised GPU or drive cables not already hard-wired would need to be purchased separately.
