550W ATX switching power supply

The KHACHIMO DPS-550LB N is a 550W ATX switching power supply built for desktop systems that need a reliable unit tested and confirmed working. It suits builders replacing a failed PSU in a standard tower or small-form-factor chassis where a single 550W rail covers the load.

Practical limits of the ATX interface

The ATX form factor limits this supply to cases and motherboards that accept the standard mounting pattern and 24-pin main connector. Systems requiring more than 550W continuous power or additional PCIe connectors beyond what this unit provides will need a higher-rated model.
