  • Modern Standby support enables rapid wake-from-sleep and improved low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for reduced consumption and cooler running
  • Zero RPM fan mode stops the fan at low to medium loads for silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine
  • ATX form factor 400W unit designed for YM-2401F compatibility

Compatible Replacement for YM-2401F

This KHACHIMO unit is a 400W ATX power supply built specifically for the YM-2401F chassis. It delivers the standard voltages and connectors that system requires and carries 80 PLUS Gold certification for high efficiency. The modern standby support enables extremely fast wake-from-sleep times and better low-load efficiency.

Verify Fit and Connector Layout

Confirm that your YM-2401F enclosure accepts a standard ATX form-factor supply and that the cable harness matches the motherboard and drive connectors inside that model. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power, but physical fit and pin-out must align with the original unit before installation.

Quieter Operation Through Design

Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation, while the resonant LLC topology with DC-to-DC conversion reduces coil whine. Together these features lower audible noise and support more energy-efficient sleep states without changing the 400W output rating.

Questions about this item

Does the KHACHIMO 400W ATX unit ship with all required power cables, or must any be purchased separately?

The power supply includes the standard ATX connector set for motherboard, CPU, drives and graphics cards; no extra cables are needed for a typical build.

The listing mentions only a 400W model — how do I know this capacity suits my YM-2401F chassis?

The unit is built specifically for the YM-2401F form factor, so the 400W rating matches the case power budget and mounting points exactly.

What does the 80 PLUS Gold rating mean for everyday use in this 400W supply?

It certifies high efficiency across the load range, which lowers electricity draw, reduces heat output and helps the Zero RPM fan stay off longer.
