A PC using an HX850 power supply (850W) had an original power cable rated 13A/125V but that cable is lost. (I know the original cable rating because I have other computers the exact same spec that aren't missing any original parts.) The power cable from this one PC has been lost and the only spare ones I can find are rated 10A/125V which appears to be much more common.
Is it safe to use a power cable with a lower amperage rating than the original? If not, what risks are there?
I imagine using a cable with lower amperage risks not providing the PC power supply sufficient wattage when it's needed. Not sure what symptoms that could translate into and how severe, but I figure much worse would be to use a higher amperage replacement cable, which could potentially send too much wattage to the power supply causing catastrophic symptoms like overheating and burning out parts.
