    Dell / Newton NPS-250DB Power Supply

    I have a Dimension 8100 on the bench where the customer wants to replace the power supply before it fails. Working fine right now.

    This one has propriety 16-pin connectors that I've not seen before. I've ID'd the PSU as E173738, Newton NPS-250DB. There is a suggestion replacement in the FSP400-60-PFB-M unit at $82.

    1) Can anybody describe the proprietary conntors?
    2) Is a Newton a candidate for recapping, or should it be replaced?

    Thanks in advance..

    Look at pinouts.ru, it's the reference about stange or proprietary pin layouts. The Dimension 8100 ATX connector is described here.

      Newton is a PSU company that is owned by Delta electronics if I remember correctly. Their PSUs are very good in terms of quality and PSU build.
      I usually buy Newton made PSUs that come from faulty Dell systems and they were perfectly, though they could have done a better job with the caps they chose for the unit. All the caps in my Newton units are made by Ltec, but none are bad. Though it would be a great candidate for a recap.

        Zandrax, many thanks. I printed that page to a PDF for my library.

        My thoughts were about getting a more standard PSU, and using the old16 pin connector with the AT12 wiring. The Blue/White 3.3v line appears to be a stumbling block.

        I have two of these PSU, both working. Perhaps it would be a better idea to recap them both, and leave them in service?

            Thanks for that one also. I found the older Dell are non-standard for their pinouts. Damn annoying, having to use factory proprietary junk.

              Newton makes very good PSUs and if it says 250 watts it IS 250 watts.

              Can usually make something work by rearranging the pins in the plastic connector.

                It sounds like recapping is a better option than preemptive replacement on this one.

                I'll haul the PSU out of the scrap 8100 I have in the bin and recap it first. Then I can swap it into the client machine without downtime, then recap that one for a spare. I have a few 8100 systems in service, so a recapped spare is a good thing.
