XPS 8940, compatible 600W power supply, replace stock 500w

XPS 8940

XPS 8940

Hi.  Is there a compatible 600W replacement power supply for the Dell XPS 8940?  I am looking to buy a 600W DPS-600EM-00 Power Supply.  The description claims it is compatible.  Stated connectors are "motherboard 8Pin, CPU 4Pin, graphics card 8(6, 2)Pin, 8Pin".

Link to unit here . . . 600W DPS-600EM-00 Power Supply For Dell Optiplex 3040 3046 5040 7040 XPS 8940 | eBay

Buyer should stay away from all untrustworthy psu carrying that “DP/N”.

That eBay site has incorrect data.

T8M40 (off of that label) is not a valid Dell part number.


The XPS 8940 never sold with a 600w PSU. Max was 500w.


The Optiplex 7040 never sold with a 600w PSU. Max was 240w.

So does that mean this aftermarket power supply is not compatible?

not sure how that psu has a official looking Dell oem label but there are a few fishy features

ebay pic has a white 8 pin (7 wired) which was only seen in 7040 Inspiron 3650, definitely incompatible with white 6 pin of 8940

Chris said the "DP/N" does not exist, at least not in official Dell part number data base.  does this mean it is a bootleg fake oem psu?

if the same "DP/N" is used in two different labels, at least one is counterfeit

Ok folks.  I think we have consensus here.  I will avoid these PSUs like the plague and stick with the 500W I have.

Thanks to everyone!
