ATX power supply for 12 V and 48 V systems

The KHACHIMO RPB-1600-24 12/48 is an ATX power supply rated at 1600 W. It delivers both 12 V and 48 V outputs for platforms that require dual-voltage distribution. The unit is supplied new and tested working.

Replaces lower-wattage ATX units when 48 V rails

A jump to this model makes sense when the build demands 48 V capability alongside standard 12 V lines. It suits upgrades from supplies that lack the second voltage or cannot sustain 1600 W continuous output.

Handles high-current 12 V

The 1600 W rating provides headroom for multi-GPU or compute configurations drawing heavily on both rails. It runs out when the combined draw exceeds the rated maximum or when a platform requires voltages other than 12 V and 48 V.

Questions about this item

What ATX case clearance does the RPB-1600-24 need for its standard mounting?

The unit uses a standard ATX form factor, so it fits any case with an ATX power-supply bay and the usual four rear mounting holes.

Which step is often missed when wiring the 12 V and 48 V outputs on this supply?

Connect the 24-pin ATX motherboard plug first, then attach the 12 V and 48 V auxiliary cables to their keyed headers; skipping the keyed headers leaves rails unpowered.

When should the internal cooling fan be cleaned on a 1600 W unit like this?

Inspect the fan intake every 6 months and blow out dust with compressed air; heavy-load systems may need cleaning every 3 months to maintain airflow.
