I have a power cord that's rated for 10A and 125V, and I'm trying to figure out if it's compatible with my power supply. I've been using a cord from my old computer for a month now without any issues, but I've heard that you shouldn't switch cords. I want to make sure I'm not risking any damage to my setup.

Yes, this kind of power cord is generally fine to use. The important thing is that modular cables for connecting components should match, but standard power cords that go from the wall to the PSU are typically standardized and safe to use. You should be okay with your 10A cord as long as it matches the voltage specs of your PSU.
Good point, but just so everyone knows, OP's cord is rated for 10 amps, which can handle 1250 watts. But be careful with the 80% rule – you shouldn't use it for power supplies over 1000W. For higher power supplies, you'd need a thicker, higher-rated cord.
Power cords usually aren’t the issue unless you're dealing with particularly high demands, like in server setups. The thickness of the cord matters more if it’s for heavy usage. Using an old cord isn't a problem at all as long as it's in good condition. Believe me, I set these up regularly, and this has never been a concern for me.

Thanks for clarifying!
