ATX power supply for XP systems

This unit delivers 48 volts at 2.9 amps in a standard ATX form factor. It is intended as a direct replacement for the ECM140US48-A-XB0287 model used in legacy XP-era machines. The module has been tested and confirmed working before shipment. Builders restoring older workstations will find it a straightforward drop-in option.

Limited to 140-watt output ceiling

The 48 V and 2.9 A ratings cap maximum power at roughly 140 watts, so the supply cannot support modern high-draw CPUs or discrete graphics cards. It lacks the auxiliary PCIe connectors required by current-generation components. Systems needing more than this rated output or additional connector types must use a different power supply.

Which version of the ECM140US48-A-XB0287 should I pick for a 48 V 2.9 A requirement?

The single model listed supplies exactly 48 V at 2.9 A, so it matches that requirement without needing an alternative version.
