XPS 8940 Desktop

Interesting, I Googled the PSU and got some conflicting results?

Some list the XPS8940. and some do not?

For example. Amazon does:

====================

=================

So I'd assume if you have one of the listed PSU's now, it should be OK?

However, Battery Club, which lists it for $50 (USD) less does not:

---------------------

● Compatible with Dell 3040 3250 3650 3046 5040 7040 7050 MT. All our products have passed CE testing and are among the best in the battery field. 

---------------------

Hopefully, someone who has done this can answer? I guess you can get it if you can return it? Just looking at the connections and be sure they are the same I guess would give you a clue if it could work?

@DELL-Chris M it appears there is a new Dell oem 600w psu with 6+4+4 white pin for XPS8940 and G5 5000 (and Optiplex 7080/7090)

DP/N T8M40

Size: 220*82*62mm

can you pls tell us if this is officially validated by Dell?

Thank you

T8M40 is not listed in the DPMD. None of those PC models above list a 600W PSU in the DPMD.
