Plugging in 8 Volts and 750 watts, we get A = 750 / 8, which is 93.25 amps.

This is what it is capable of. Not what we actually use. What we actually use as way below that, generally 5 to 8 amps at full stall. Which, at 8 volts, is 40 to 64 watts. Well within the specs.

Again, it's the wires that are the limiting factor.

I believe the 250V rating is a conductor spacing/isolation specification
3A is the contact current rating

While Power does equal Voltage * Current (ignoring power factor), you can't simply multiply the 2 connector specs ... it doesn't work that way

If you don't believe me try this ...

Take a 1V source and see if the connector can pass 750Amps
According to your math it should since 3*250 is the same as 1*750
