So I want to power my backplane with 6 blades on with a ATX power supply because the server PSU is very much too noisy.

Is there some guide with pictures what exactly to extend and cut and scew into the backplane? And how many wires I need for 6 blades?  Because I am sorry but this guide didn't really make me any wiser on which wires to connect...

Best I can figure is something like putting one yellow wire from PCI-e into each of the 4 screws where is says 12V and one black wire in each screw where it says GRN.
This will probably burn everything up though so I need some more input please.
