3000W ATX power unit

This KHACHIMO R48-3000A3 is a 3000W ATX switching power supply built for systems that demand very high output. It arrives new and has been test-worked by the supplier to confirm operation. The unit targets workstations, servers or multi-GPU rigs where sustained heavy load is normal.

Who this suits and who should look elsewhere

Builders assembling high-density compute nodes or rendering farms will find the 3000W rating appropriate. Buyers who want more storage, extra PCIe connectors or a lower-wattage design for a standard desktop should look elsewhere. The form factor is ATX, so chassis compatibility must be verified before purchase.

The specification that decides fit

The single figure that decides fit is the 3000W maximum output. If the total system draw under full load stays below that ceiling, the unit can deliver; if the build requires more headroom, this model will not be sufficient.

Questions about this item

Will the 48 V rail need periodic recalibration or replacement?

The 48 V output is a fixed switching design with no user-serviceable calibration points; replacement is only required if the unit fails.

What limit appears first when the 3000 W supply runs continuously at full load?

The 3000 W total power ceiling is the first hard limit; sustained operation at that level depends on adequate case airflow.

How loud and hot does the R48-3000A3 get during all-day operation?

The unit uses a temperature-controlled fan that speeds up under load; expect moderate noise and warm exhaust when delivering continuous high power.
