These adapters have become fairly difficult to source, and expensive. It should be fairly easy to hack one together with a 20pin ATX extension cable or a 24 to 20 pin ATX adapter, plus the 6pin P10 connector which can also be sourced from old/dead early ATX PSUs. The issue is, I do not have the pinout. Does anyone have it lying about?

Sure, it's here: https://pinoutguide.com/Power/dell_atxpower_pinout.shtml

With some of the motherboards, you can shift the ATX connectors position to make it ATX compatible again: A Permanent Solution to the Dell 'Fake ATX' Power Supply Problem?

Here's a graphic to show how it's shifted and where the clips etc are that I just put together in Excel - I've checked this against my own Dell Dimension XPS D233 to confirm:

All you do is take a standard solder ATX connector, take out both dell connectors, and open up the solder holes for the ATX, solder the ATX connector in. Dell connector has one pin missing.

I like Dells of this era but jeeze it was a dick move not to use the ATX standard. Especially when it was found the motherboards even had solder points for a stranded connector

I can't remember who made them or the name of the threads, but Im pretty sure somewhere around here someone has solved this issue. What is described is exactly it besides using a diagram to follow along. An adapter does the same thing.
