What is 20 24 pin ATX connector?
The 24 pin motherboard connector is actually just the 20 pin connector with 4 extra pins added on the end. The original 20 pins were unchanged. The extra 4 pins are not separate rails. They’re just extra lines to provide more current to the same rails.
What do I plug into ATX 12v?
You’re currently looking at the “PCI-Express 8-pin & 6-pin compatible.” This plugs in to video cards. You want the “EPS/ATX12V 8-pin & 4-pin compatible.” This is what you’re going to plug into your motherboard in the jack nearby the CPU.

Can you plug a 20 pin power supply into a 24 pin motherboard?
Many power supplies come with a 20+4 cable which is compatible with both 20 and 24 pin motherboards. A 20+4 power cable has two pieces: a 20 pin piece, and a 4 pin piece. If you leave the two pieces separate then you can plug the 20 pin piece into a 20 pin motherboard and leave the 4 pin piece unplugged.
