myVolts Power Supply for HP EX475 EX495 350W

Replacement for HP MediaSmart EX475 EX495

This power supply is a direct drop-in replacement for the HP EX475 MediaSmart Server and EX495 models. It matches the proprietary wiring and electrical flow of the original HP-U200EF3 and FSP270-60LE-MS units. No re-modification of the server chassis or cabling is required for installation. It is built for owners needing a reliable new unit to restore server operation.

350W maximum output with AT form factor

The unit delivers a maximum of 350 watts, which is higher than the original 270 watt rating referenced in the part number. This extra headroom allows for additional internal upgrades such as extra drives or expansion cards within the server's power budget. The supply uses an AT type design specific to these legacy HP server platforms. Total system draw must remain within the 350 watt limit to ensure stable operation.

Drop-in fit with proprietary wiring

Installation is straightforward because the unit is specially wired to match the original HP pinout exactly. The most common issue with generic replacements is mismatched wiring that prevents the server from posting or causes instability. This model eliminates that risk by replicating the unique electrical flow of the OEM part. Buyers needing a standard ATX pinout for a custom build should look elsewhere as this unit is not compatible with standard motherboards.
