Confusing DELL PSU

[Keller1233]

Hi, Im looking to upgrade my ageing DELL XPS600 with a new motherboard. Well its not new, its my old i7 Bloomfield system that I wish to replace the even older XPS Pentium 4 system.

I have looked through all the system manuals and technical data and swapping the motherboard and necessary components seems straight forward.

However the problem lies in the PSU. The ASUS motherboard requires the 8-Pin EPS connector, but the DELL PSU for some strange reason comes with a 10-Pin connector.

I was wondering if it would be safe to plug in the 10-pin one into the EPS with 2-pins left "hanging"???

This is the detail wiring diagram for the connector, it seems ok:




Thanks for your help

Be careful with that old Dell PSU. The P4 systems were right around that era when Dell was still using proprietary PSUs and motherboards. They were wired completely different from conventional ATX PSUs and the corresponding 24 pin header on motherboards. Used on a modern-ish board, they will fry the board due to crossed wiring. It is mainly the 24 pin header that is the issue.

Since you are using a more modern board, you may want to pick up a new PSU and keep the old one with the old board.

As long as the D and square shapes of the connector properly fit into the motherboard's CPU power socket it should work.

Thanks for pointing that out, however the article you have mentioned states that "all 24-pin ATX connectors are not affected by this issue" (which the XPS600 has)??

Based on the pinout specified in the Dell XPS 600 Service Manual it exactly matches the standard ATX12V 24-Pin motherboard connector's pinout.

Then you should be OK. Dell made the transition from proprietary to standard ATX right around the P3 to P4 era. I wasn't sure the exact time.

Thanks everyone for the help, the PSU probably will work, but Ive just realised that the front panel i/o on the case is proprietary and therefore would not connect to the motherboard!!!!

I might just be better off with a new case.
