I am making a power hub out of an old ATX PSU. All wires will be stripped except Molex (and maybe SATA) connector wires. 12V will be connected to barrel jacks, PC fan sockets, and (maybe) lighter plug sockets (the plugs in a car). 5V will be connected to a dummy load, USB sockets (and maybe more barrel jacks). 3.3V will be connected to 2xAA battery eliminators. When I attempt to charge my phone off the connected USB ports, the USB to Lightning wire gets hot that the glue even melts (PSU wires normal temp). I have been powering 12V multimedia devices with the 12V barrel jacks, powered PC fans with the makeshift fan sockets, charged BT speakers and powered USB fans with 5V without problems. How to stop that?
