High-output ATX power supply

The KHACHIMO R4875G1 DMA-48-75 is a 4000W ATX unit built for systems that demand very high power delivery. It is intended for workstations or specialised rigs where multiple high-draw components run simultaneously. The unit has been test-worked and is supplied new.

Suited for extreme multi-GPU or compute builds

This supply fits builders assembling platforms with several power-hungry graphics cards or accelerator cards that together approach the 4000W rating. It is not for standard gaming PCs, office workstations or compact chassis where such output would be unnecessary and the physical size would be impractical.

4000W maximum rated output

The single figure that determines suitability is the 4000W peak rating. If the total system draw under full load stays well below this level, a lower-wattage unit will be more efficient and easier to fit; only choose this model when the build genuinely requires power delivery at this scale.

Questions about this item

What ATX motherboard and case will this 4000W unit fit?

The ATX form factor matches standard ATX motherboards and cases, so it installs in any chassis built for ATX power supplies.

Will the DMA-48-75 4000W supply power to older components that use the same ATX interface?

Yes, the ATX interface is backward compatible, so legacy parts that draw power through standard ATX connectors will operate normally.

How do I confirm the R4875G1 is working after installation?

The manufacturer marks each unit as test working; power on the system and verify stable operation under load to confirm it functions as intended.
