Attention open a power supply is very dangerous, even unplugged. There is a lot of risk to your life. Made a professional if you do not mastered the principles of electricity. I decline any responsibility on you and your equipment when tampering on your part.
• First unplug the power supply. And unload components, check for tension using a multimeter. • Then open your power supply to identify 12v rails. They are generally rated on the printed circuit. As the picture:
My power supply has 2 RAIL + 12V (+12v1 and +12v2). You can use several ways, iron welded, cut and son connected with small connectors. Attention the connector is seen from below
The + 3.3v and + 5v will not be used.
The + 5V Standby (green wire) is useful to maintain a current in the motherboard when is power off, for example wol. And DC On (purple wire) is used to boot the PC. You must have this at the end
