As per title, how is it that extension cables are designed to be compatible with ANY PSU, but when you mix different brands of PSU cables - for example, corsair vs cooler master - you will fry your pc?

pls explain

Extension cables are straight through. Pin 1 to Pin 1 and so on, they in effect do nothing but extend and add a little wire resistance.

PSU manufacturers have not agreed to standardize on modular PSU connectors. If you go back even farther it was MUCH worse.

Effectively DIN connectors

In-line connectors
