I've noticed lately that places to learn about both power supply cables and also peripherals and fans aren't that easy to find.

There's very little information available that gives detailed explanations of what cables are used inside a computer. What I found was very dated and often lacked detailed explanations.

For someone planning out their first build it would be great way for this to be explained all in one place, like here!

Important things to know about cables and connections in a computer?

• What are their names?

• Where do they connect to and why?

• What typical Voltages do they output?

• Changing Voltages for Overclocking?

Please refernce PSU cables(Full modular, Modular and Non-Modular,24-pin, 20+4-pin etc), SATA(I, II, III), Molex etc.

EDIT:

Forgot to mention any information about PSU rails would also be appreciated :)
