400W ATX power supply

The KHACHIMO FSP400-62PFB is a standard ATX power supply rated at 400 watts. It is designed for desktop builders who need a straightforward replacement or a basic unit for a new system assembly. The unit arrives new and has been tested working by the supplier.

Tested working assurance

Each unit undergoes a functional test before dispatch, confirming that it powers on and delivers its rated output without faults. This verification step reduces the chance of receiving a dead-on-arrival component and saves troubleshooting time during the build. No additional software or bundled accessories are included with this model.

ATX form factor compatibility

The ATX form factor ensures the supply fits standard desktop chassis and aligns with common motherboard mounting points. Standard ATX connectors provide the necessary links for motherboard, CPU, and peripheral power. Builders requiring higher wattage or modular cabling for cable management should consider other options.
