Pc power cord, very small gauge
 

I have 1 pc power cord that is much smaller than the others I have. I want to use it because it is so short (I hate having extra cord lying around) but the diameter of the cord is much smaller than a normal one. Does the gauge matter?

Thanks pc gurus

It should show the wire gauge (AWG) on the side.

A 500W power supply at full power is going to run a little over 4 amps.

22 gauge wire is good for 5 amps. I don't think you have anything to worry about. Even 24 gauge is good for 3.5. Being short helps too.

It says "10A" over "250V" and my power supply is 750 watts. Am i good?

You're good.

that should work, its all about the voltage
