To jump a PC power supply (PSU) for testing, you short the green "Power On" (PS_ON) wire to any black ground wire in the 24-pin motherboard connector using a bent paperclip, which tricks the PSU into thinking the motherboard is connected, making its fan spin up. Always turn off and unplug the PSU first, then connect the paperclip, then plug it in and flip the PSU's back switch to test. This method is great for powering components like water pumps or testing the PSU itself.
