So I wanted to get 3 monitors going, and someone on Twitter alerted me to the fact that you can put any graphics card in your computer and run a 3rd monitor from it - you don’t need to SLI them or even be the same brand.
So cool - I grab another graphics card and jam it in.. but it doesn’t work. The computer doesn’t even boot. Then I realise that the power PCIE cable I’m using to go from the PSU to the graphics card isn’t made for this PSU.
Then I decide to make my own. How hard can it be? I already have one working cable - I just have to pull the pins out of the connectors, put them in the right order and then splice the two cables together - again in the right order.
I did this carefully. I tested the connections to each wire and verified that they matched up. They were identical. I tested again. Yep. Identical. Tested again.
Then it came time to put it in. I somehow put the GPU side in the PSU, and the PSU side in the GPU.
Fried motherboard. Oops.
