I have some salvaged wire from a computer power supply and would like to know it's break-down voltage rating. Most hookup wire is rated at 600 volts but unfortunately, all computer stuff is now made in China. The repair job of a vintage piece of equipment requires wire that can withstand 300 VAC.
Computer power supply cables do not deliver anything like 300 volts, so I would say no, don't risk it.
Well as it turned out, wire ratings are stamped on the jacket and after a quick look-up, determined salvaged wire from the typical computer power supply is rated for 300 volts.
i couldn't tell you without knowing the amperage in those 300vac because amps are what generate the heat but if you wanna know if its high quality or not strip the psu wire and if its silver its good wire if its copper..... use at your own risk
