4000W Rectifier Module ATX

The KHACHIMO R4875G1 DMA-48-75 is a 4000W rectifier module built to the ATX form factor. It is intended for system integrators and operators who need high-density AC-to-DC conversion in rack or server environments. The unit is supplied new and has been tested working.

ATX form factor integration

Because it follows the ATX outline, the module fits standard mounting frames and bus-bar arrangements without custom brackets. Its rectifier topology removes the need for separate bulk converters, freeing internal space for compute or storage cards. Installers should verify that their chassis provides the required airflow and DC distribution bars.

4000W continuous capacity

At 4000W the module delivers substantial headroom for multi-GPU compute nodes or dense storage arrays. The 48 V and 75 V output rails support mixed loads, but the single-unit design means redundancy requires additional modules. Buyers needing N+1 resilience or power levels beyond 4000W must plan for parallel units.

Questions about this item

What is the continuous power limit of the 4000W rectifier module under sustained load?

The module is rated for 4000W continuous output, so that figure is the ceiling you hit first when the unit runs at full load for extended periods.

How much heat does the ATX rectifier module produce during all-day operation?

At 4000W output the unit dissipates the difference between input and output power as heat; expect substantial thermal output that requires adequate airflow in the rack or chassis.

What DC voltage source must already be present for the 48V input rectifier to function?

The module requires a 48V DC supply capable of delivering at least 75A on the input side before it can produce its regulated ATX output.
