400W ATX Power Supply for PRT Systems

This 400W ATX switching power supply is built for PRT platforms that require a PRM400 compatible unit. It delivers standard ATX voltages for desktop components in industrial or legacy configurations. The unit is supplied new and has been tested working by the supplier.

Straightforward ATX installation with PRT fitment

Installation follows normal ATX mounting and connector routing, but the chassis must accept the PRM400 form factor and connector layout. Problems usually arise when the case or backplane expects a different pin-out or physical profile, so verify compatibility before fitting.

The power supply was tested working before shipment; after fitting it, the system should boot normally and remain stable under load.

The package contains the 400W ATX power supply only; mounting screws, power cord and any adapters are not included and must be purchased separately.
