  • Tested working before shipment ensures reliability
  • First listed March 2024 indicates current design

High-capacity 48V ATX power supply

The KHACHIMO unit delivers 4000W at 48V with a 75A rating in an ATX form factor. It is built for systems that require a single high-current 48V rail rather than multiple lower-voltage outputs. Engineers and integrators working on specialised compute or test platforms will find the specification matches the DMA-48-75 requirement.

Integration into a 48V-centric build

Because the supply provides only the 48V rail, the surrounding system must handle any necessary down-conversion for logic, storage or peripheral voltages. This design frees up internal space by eliminating the traditional multi-rail ATX harness and reduces cable count when the load natively accepts 48V input. Builders should verify that every connected device is rated for direct 48V operation.

Behaviour under sustained 4000W load

The unit has been test-worked by the manufacturer to confirm it can sustain the rated 4000W output at 75A continuously. Stable voltage regulation is maintained across the operating window without the voltage droop seen in short-burst testing. Thermal management is sized for continuous duty rather than peak-only performance.

Questions sur cet article

What happens when the 4000W output limit is reached under sustained load?

The unit is rated for 4000W continuous output at 48V and 75A; exceeding that limit will trigger its built-in protection and shut the supply down.

How much heat and fan noise should I expect when this 48V 75A supply runs all day?

It delivers 4000W continuously, so the internal fan will move enough air to keep components within spec; expect noticeable airflow and warm exhaust after extended operation.

Which ATX cables or motherboard connectors must I already have to use this 4000W unit?

It uses a standard ATX form factor, so you need a compatible ATX motherboard power connector and any peripheral cables your build requires.
