Drop-in Replacement for EX495

This power supply is a direct replacement for the HP MediaSmart Server EX495 using part numbers HP-U200EF3 or FSP270-60LE-MS. It matches the unique wiring and electrical flow of the original unit so no re-modification is required. It is intended for owners restoring or maintaining this specific server model.

350 W Maximum Wattage

The unit delivers a 350 W maximum output, which exceeds the 270 W rating of the original FSP270-60LE-MS supply. This higher headroom supports additional internal upgrades such as extra drives or expansion cards. The increased capacity helps the server handle heavier workloads without exceeding the power budget.

AT Form Factor Server Integration

Built to the AT form factor, the supply fits the EX495 chassis and connects to the existing backplane and drive cages. It frees the builder from sourcing obsolete proprietary units and enables further storage expansion within the original enclosure. The design preserves the server's factory cooling layout and mounting points.
