KHACHIMO 300W ATX Power Supply

This 300W ATX power supply suits compact desktop builds and system integrators who need reliable, efficient power delivery in a standard form factor. It is designed for configurations where a 300 watt output matches the total component draw.

Modern Standby and Connector Check

Verify that your motherboard supports Modern Standby to use the fast wake-from-sleep capability. Ensure the unit's fixed cable set provides every connector your current components require before ordering.

Zero RPM Fan and LLC Topology Benefits

The Zero RPM mode stops the fan completely at low and medium loads for near-silent operation. The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine and enabling efficient sleep states.

Questions about this item

What cables come attached to this 300W ATX unit and what must I source separately?

The power supply has fixed cables for the motherboard, CPU and peripherals, so a standard build needs no extra cables.

Should I choose the FSP300-50ATV(PLUS) or the older FSP300-60ATV(PF) for a new system?

The 50ATV(PLUS) is the upgraded version with Modern Standby support, 80 PLUS Gold efficiency and a Zero RPM fan mode.

What does the 80 PLUS Gold rating actually deliver inside a running PC?

It means higher efficiency at typical loads, which lowers power draw, reduces heat output and lets the fan stay off longer.
