So the power cable of my PC stopped working and I’ve had to replace it, and looking around our stash of spare cables I found one, but this one says 10A=250v whereas the original cable was 10A=125v. I’m just wondering if this is important and if I should only use same A=V cables? Because I plugged it in and my PC works just fine but I’m a little concerned it might damage something internally.

The C13 power cable that plugs into the back of most computers uses a standardized connection. Almost all cables that fit this shape will perform just as well as others. Note, some companies provide extra heavy duty versions for high power applications (High power gaming rigs for example).

Usually you will see some variations between US manufacturers and International suppliers. America runs off 120v from the wall, while nearly everyone else runs 240v. Since they supply roughly the same power, a cable designed for US will say 10A at 120V, and 10A at 250v internationally.
When it comes to smaller devices and USB chargers. It’s a little trickier, but usually works for a while anyways as long as it is enough power. Not enough power and it won’t be able to activate or run the device. If you have too much power their is a chance of component failure, and either a grounded circuit or a short with that burnt smoke smell. So, it’s really good to try and stick around the same power ratings as the manufacturer intended.
USB follows a standard specification, so these are all interchangeable, but should still try to match a little for better performance and battery life.
