Default [HOW TO] Dell Precision T3600 PSU Swap

I am writing this to you as I have successfully swapped the standard proprietary PSU from Dell to a Standard ATX Power Supply. This was no small feat because as usual Dell likes to do things stupid.

What you will need:
1) Male to Female ATX extension cable
https://www.amazon.ca/dp/B000FL60AI/...709270_TE_item

2) 6 pin PCI-E Extension Cable
https://www.amazon.com/StarTech-Expr...dp/B001TK3TJY/

Other things you will need are a multimeter, depin tools, soldering iron, shrink tube and soldering iron.

From there I basically plugged everything in and then started probing the connector to come up what wire does what so that I could properly make the extension.

Some interesting things I discovered was that this particular machine uses 2 of the +5vSB wires so you'll need to make a splice for that and the other discovery was that a wire that normally read +5v was actually a ground.

Another was that the Dell PSU supplies 3 additional 12v rails which is why you need the 6 pin extension cable to feed these three extra connections.

Basically you are going to depin and repin the ATX extension to match the feed wires from the new power supply into the male connector to match to the Dell power supply. You then add the 3 additional 12v lines for the PCI-E cable and splice and solder the 2nd +5v SB connection.

You will end up with a connector as I have included.

You really like to play around with the soldering iron, eh?

Anything related to combining metals with heat is #1 priority for us men.
