420W ATX Power Supply for 1U Rack Servers

The KHACHIMO SP423-1S delivers 420 watts of ATX power in a compact 1U switching design suited for rack-mounted servers and space-constrained workstations. It is intended for system builders replacing a unit in compatible enterprise chassis or integrating into custom 1U enclosures. Tested working and built for reliable operation, it fits environments where standard ATX depth cannot be accommodated. Buyers needing higher wattage or redundant modules should look elsewhere.

Verify Chassis Mounting

Confirm that your case accepts a 1U form factor and that the mounting holes align with the SP423-1S layout. Check that the output connectors match the motherboard and backplane requirements of your specific platform, as pin configurations can vary between vendors. Ensure the total system draw stays within the 420 watt rating. This unit is not suited for full-size tower builds or configurations requiring modular cabling.
