420 W ATX power supply for standard builds

The KHACHIMO MRW-6420P-R is a 420 W ATX power supply built for everyday desktop computers. It delivers the standard voltages required by typical motherboards, processors and graphics cards in office or home systems. The unit is supplied new and has been tested working before shipment.

Continuous 420 W output rating

The single specification that determines compatibility is the continuous 420 W power rating. This figure defines the maximum combined load the unit can sustain across all rails. Systems with high-end graphics cards or multiple drives may exceed this limit, so builders planning such configurations should look for a higher-wattage model.

Tested working status ensures immediate use

Each unit is verified as test working, which reduces the chance of a dead-on-arrival component. No extra cables, adapters or software are bundled beyond the standard ATX connectors attached to the unit. The package therefore contains only the power supply itself, ready for installation.
