48V ATX Power Unit

The KHACHIMO 48V PMU 01B is an ATX power supply designed for systems that require a 48V input architecture. It targets builders assembling modern standby-compatible PCs who prioritise efficient low-load operation and silent running at typical desktop workloads.

Compatibility Check

Verify that your chassis accepts a standard ATX form-factor unit and that your motherboard and components are designed for a 48V power delivery architecture. Confirm the unit’s connector complement matches your GPU, storage and peripheral requirements before ordering.

Sustained Load Behaviour

An 80 PLUS Gold certification ensures high efficiency during continuous operation, reducing waste heat and keeping internal temperatures lower. The resonant LLC topology with DC-to-DC conversion delivers clean, stable power under sustained demand while minimising coil whine. The Zero RPM fan mode remains inactive under prolonged heavy loads, allowing active cooling to maintain consistent thermal performance.

Questions about this item

What cables and connectors come with the KHACHIMO 48V PMU 01B, and what must be purchased separately?

The unit includes the standard ATX power supply cables required for a typical build; any specialised adapters or extension cables for non-standard components would need to be sourced separately.

Which version or capacity of the KHACHIMO 48V PMU 01B should I choose?

Only the 48V PMU 01B model is offered, so there are no alternative versions or capacities to select from.

What does the 80 PLUS Gold rating mean for daily system operation?

It guarantees high efficiency across typical loads, which lowers power draw, reduces heat output and allows the fan to stay off longer during light use.
