350W 24V ATX power supply for low-load efficiency

This KHACHIMO ATX unit delivers 350 watts on a single 24 volt rail rated at 14.6 amps. It carries 80 PLUS Gold certification and Modern Standby compatibility, making it suitable for systems that prioritise fast wake times and reduced idle power draw. The resonant LLC topology with DC-to-DC conversion aims to provide clean power and minimise coil whine.

Standard ATX mounting with Zero RPM fan mode

Installation follows normal ATX screw patterns and connector layouts, so it fits typical chassis without adapters. The Zero RPM mode keeps the fan off at low and medium loads, but the fan will spin up under sustained heavy load; ensure the case airflow path does not block the intake or exhaust. Cable routing is straightforward, though the fixed cable set may leave unused leads in smaller builds.

Check 24V rail demand and ATX form-factor clearance

Verify that your components draw primarily from the 24 volt rail and that total load stays within 350 watts. Confirm the case accepts a standard ATX power supply and that there is enough depth for the unit and its cable bend radius. Modern Standby features require a compatible motherboard and operating system to function.

Questions about this item

How can I confirm the power supply is delivering stable 24 V output after installation?

Check that the system powers on reliably, monitor the 24 V rail in BIOS or software for steady voltage, and verify the fan stays off at low load thanks to Zero RPM mode.

Which cables and connectors are included with the S8JC-Z35024C-802 and what must I source separately?

The unit ships with the fixed ATX cable set; any specialised GPU or peripheral cables not already attached must be purchased separately.

Should I choose the 350 W 24 V 14.6 A model or a different capacity for my build?

Select this 350 W 24 V 14.6 A version when your system draws up to 350 W on the 24 V rail; choose another capacity only if your load exceeds that figure.
