3Is ATX 20 or 24 pin?
A 24-pin power supply should work with older motherboards that only have a 20-pin connector. Both connectors’ first 20 pins are the same, and the final four pins go unplugged if they aren’t connected to the motherboard. The last four pins on some power sources are part of a detachable connector.
On the other hand, using a 20-pin power supply on a newer motherboard intended for a 24-pin power supply may be possible, but it will result in an unstable system. There are adapters that add the extra four pins, but these rarely work as well as a true 24-pin power source. It is usually safer to use a power supply that is specifically tailored to the computer’s needs.
And on computers with a 24-pin power supply, additional connectors may be needed for parts that require large amounts of electricity. Hard disks and optical drives often need their own connectors.

Pinout of ATX (ATX) Wikimedia Commons Below is the complete pinout table for the ATX 4-pin (2×2) 12V power connector as of Version 2.2 of the ATX Specification (PDF).
If you’re using this pinout table to measure power supply voltages, be aware that the voltages must be within ATX approved tolerances.
5What is the difference between 24 pin and 20 4 pin?
6Can I use a 24 pin power supply on a 20 pin motherboard?
Although this is an option you should try, we don’t necessarily recommend it.
7What is the function of 20 pin connector?
This cable is now a 24-pin cable and no longer a 20-pin cable with the introduction of ATX-2.
The ATX cable connector in the photos has a small clip on the top that snaps and holds the cable in place. This cable is also keyed, implying that it only connects in one direction.
A 24-pin connector power supply can be used on a 20-pin connector motherboard by leaving the four additional pins disconnected. However, if you have a 24-pin connection on your motherboard, all 24-pins must be connected. If you’re using a 24-pin connector, you’ll need to buy a new power supply.
Warning: When using a connector like the one shown above, be sure that the arrows point to each other. The arrows must point to each other in order for the cable to be properly attached.
