I am pleased to announce that OverTek LTD in the UK has a new direct replacement PSU for the HP MediaSmart and Data Vault servers. Back in July 2010 we first learned about OverTek LTD offering a direct replacement PSU for the HP MediaSmart Server. Since then I have had the opportunity to actually test one of their PSU’s and have been pleased with its performance.
What makes OverTek special is they modify an existing high quality FLEX ATX PSU to ensure it is wired properly for the HP MediaSmart and Data Vault and then properly terminate the unnecessary wires that are not needed. What others offer is a PSU which will directly fit but lack the necessary wiring modification needed to make the PSU actually work, requiring the end user to modify the PSU on their own. You can learn more about the MediaSmart power supply in our Wiki.
The new PSU is actually manufactured by Seventeam a manufacturer of PC and IPC PSU’s in Tiawan and Guandong Province China who has been manufacturing PSU’s since 1986. The new PSU is a 300w FLEX ATX PSU which is bump up from the typical 200-250w PSU, so this unit will more than handle anything you throw at it reducing the risk of overloading it and having a premature failure.
The power supply is also quiet. Overtek has provided this PDF document highlights that in the power region HP Mediasmarts tend to operate, up to 100W, forced cooling remains at a minimum which means the noise levels stay very quiet at around 20dBA.
