300W ATX supply for Modern Standby systems

This KHACHIMO H3C unit delivers 300W of continuous ATX power and carries 80 PLUS Gold certification. It targets builders or upgraders working with compatible H3C MSR 3600, 3640, 3660 or 5600 platforms that require Modern Standby support and efficient low-load operation.

Verify ATX fit and Modern Standby readiness

Confirm your chassis accepts a standard ATX form-factor supply and that the motherboard firmware enables Modern Standby sleep states. Check that the existing cable harness reaches all required connectors for the target platform and that the 12V rail capacity matches the system design.

Zero RPM fan and LLC topology reduce noise

The Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion supplies cleaner power, cuts coil whine and supports the deeper sleep states used by Modern Standby configurations.
