Replacement for HP MediaSmart Servers

This 350 watt AT power supply is wired specifically for HP MediaSmart Server models 470, 475, 480, 485, 487 and 490. It serves as a direct drop-in replacement that requires no re-modification of the chassis or cabling. Builders restoring or maintaining these servers can install it without adapter cables or wiring changes. The unit is not suitable for standard ATX motherboards or servers with different pinouts.

350 Watt Capacity and Upgrade Headroom

The supply delivers a maximum of 350 watts, providing greater wattage than the original units for more upgrade possibilities. It comfortably handles the server's stock drive complement and typical expansion cards within the original chassis limits. Headroom runs out when multiple high-draw drives and add-in cards exceed the 350 watt ceiling, so total system draw must stay within that figure. Buyers planning dense drive arrays or power-hungry expansion cards should verify their total load first.

Drop-In Fit for Existing Chassis

Because the wiring matches the factory design, the supply fits the existing mounting points and connectors without modification. It frees the builder from sourcing proprietary cables or repinning connectors, saving time during a swap. The AT form factor aligns with the server's original power architecture, so no case alterations are needed. Systems requiring redundant power modules or hot-swap backplanes not present in these models will not be supported.

Questions about this item

Will the 350W myVolts unit fit and power my existing HP MediaSmart EX470 without rewiring?

Yes, it is a drop-in replacement specially wired for the EX470, EX475, EX480, EX485, EX487 and EX490, so no re-modification is required.

How can I verify the new 350W supply is operating correctly once installed?

The server should power on normally, all drive bays spin up and the system posts without shutdowns or instability under load.

Does the box include the power cord and mounting screws, or must I source them separately?

The unit comes as a complete replacement power supply; reuse the original AC cord and chassis screws from your MediaSmart server.
