300 W ATX power supply for compact builds

This KHACHIMO unit delivers 300 W of continuous power in a standard ATX form factor. It is suited to office desktops, small-form-factor PCs and basic home systems that do not require high-wattage headroom. The 80 PLUS Gold rating ensures efficient conversion at typical loads. Modern Standby support allows near-instant wake from sleep states.

Practical limits of ATX 300 W capacity

A 300 W ATX supply can run a modern CPU with integrated graphics, a modest discrete GPU and a few drives, but it cannot sustain high-end graphics cards or heavily overclocked processors. The fixed cable set and single EPS connector restrict multi-GPU layouts or boards that demand dual CPU power. Builders planning significant future upgrades will need a higher-capacity unit.

Capacity and headroom for everyday workloads

At 300 W the unit comfortably handles web browsing, office applications, media playback and light gaming without spinning its fan thanks to the Zero RPM mode. Under sustained heavy loads such as rendering or extended gaming sessions the fan engages and efficiency remains high, yet the hard 300 W ceiling leaves no margin for power-hungry components. Users who anticipate adding a high-TDP graphics card should look elsewhere.
