dubbySwords Posted July 26, 2022 Report Share Posted July 26, 2022 Hi! I'm converting an ATX pc power supply to a lab power supply. My concern is which wire/cable gauge or size to use for the 5v, 12v and gnd . I have cable rated at 700/500v but I assume this is for AC. Can one safely use this with DC? /D Quote Link to comment Share on other sites More sharing options...
admin Posted August 1, 2022 Report Share Posted August 1, 2022 Wire gauge is important for the amount of current it can carry without significant heating. If you are going to pull much current from the power supply then you need thick wires, otherwise normal gauge will work. Quote Link to comment Share on other sites More sharing options...
