I'm looking to learn more about power requirements and such that a Power Supply/Computer work with.
I see this image
and it has a lot of different pin layouts for various things and such.
For a few projects of mine I'm looking to connect up to the power supply.
I've heard I only need 1 12V+ and 1 ground, but I also need a 5V+ and a ground for another part of the project.
I'm curious if it matters where this is taken from on the whole?
I'm also curious, looking at that 24-pin connector, why the MB needs all of those values? 3.3v, 5v, a bunch of 12 volts....
Does that all get split into individual things or...? I see the VGA connector is 3 12V, and 5 grounds, so I'm curious if individual parts of the GPU require 12V+ or if it requires 36v total, or whatnot?
Essentially I'm just curious how power works, how you know how much voltage, and amps and such you need to power your devices, and all that stuff with connectors and such, to make sure you have the proper power inputs and such?
Any advice is appreciated, thanks a lot!
