- In this video from ITFreeTraining I will look at all the different connectors on the motherboard. If you are planning on building a computer or upgrading a computer, you will need to understand what all these connectors do and how to plug them in.

Motherboard Diagram
0:14 Every motherboard, I have yet to see one that has not, will have a diagram in the manual showing the locations of all the connectors on the motherboard. If you have trouble locating a connector, have a look in the manual. If you don’t have the manual, you will be able to download a copy from the motherboard manufacturer’s website.
Main Power Connector (P1)
0:33 To start with, I will have a look at the main power connector, otherwise known as the P1 connector. The connector will be 20 or 24 pins in size. The 20-pin size is an old connector and unless you’re working with an old computer you won’t come across it. Most power supplies will have a 24-pin connector that can be divided into a four pin and 20 pin plug if required.
With some power supplies, the connector will be all one part and cannot be divided. If you come across this and need the 20-pin connector you have two choices. You can purchase an adapter to change the 24-pin plug to a 20 pin plug or you can attempt to plug it in anyway. It will go in, but will be a tight fit and four of the pins will be hanging out of the plug. Just make sure if you do this that you are plugging it in the right way.
You will notice this P1 connector is 24 pins, however it can be divided into two separate plugs. This motherboard has a 24-pin connector so I will combine it back into one plug.
Every connection on a motherboard nowadays is keyed. This means it is not possible to put a connector in the wrong way unless you use a lot of force which most likely will damage something in the process. If you find you are having to force a connector, double check the plug, you probably have it the wrong way around.
You will notice that the plug on the motherboard has a small notch. This will hook onto the latch on the plug. I will now plug in the P1 connector. When the P1 connector goes into place, you should hear a click.
The click is the latch on the plug; once you hear that, you know the P1 connector is in place. Once the P1 connector is plugged in, five volts of power is supplied to the computer continuously. Essentially the computer is in standby mode and this five-volts powers standby devices. For example, if you have wake-on-LAN, the five volts allows the computer to monitor for a wake-on-LAN event and start the computer up. It is possible to have devices like the keyboard start the computer from standby if your computer supports it.
As time moved on, computers required more and more power. First, the 20-pin connector was not enough and then the 24-pin connector was not enough.
P4 Connector
2:54 In 2003 the power supply standard was updated to include what is commonly referred to as the P4 connector. The P4 connector is a four-pin cable supplied by the power supply. It supplies the motherboard with additional power.
The P4 connector is generally near the CPU. Like the P1 connector, it can only be plugged in one way and you should hear a clicking noise when it is in place. Don’t get this confused with the extra four pins of the P1 connector. These connectors are not compatible and are keyed differently.
If you find that your power supply does not have the P4 connector, you can always purchase an adapter cable. In some cases, you will find that some of the older motherboards may still work without a P4 connector. You may start experiencing problems if you add new or additional video cards that use a lot of power. New motherboards tend to require the P4 connector and won’t start up without it.
The extra power supplied by the P4 connector was good, but as time passed, there was a need for even more.
EPS 12V
4:00 To provide more power to the motherboard, the four pin P4 connector was expanded to an eight-pin connector. This is called the EPS 12V. Most of the time it will be referred to just as the EPS connector.

Nothing has helped me more than your videos... So complete knowledge, enabling you to handle technical issues, looking forward for the next video!!
The best and the most complete explanation of motherboard cables and sockets.
Bro wrote this like a quote on the back of a book
What a great and reliable source of information! Thanks for creating this masterpiece.
Glad you enjoyed it!
Extremely well presented and extremely helpful information. I haven't played with the motherboard for at least 30 years now. So many things have changed.
Thanks very much.
Excellent assistance with no needless commentary. Helped me figure out the front panel connection on an older Gateway computer (a nightmare without help). I have gladley subscribed
Thanks, glad we could help. We are re-do this video at the moment trying to make it better.
Hello! I just want to say, I've been building computers for a while now, but you touched on stuff that I never knew or could never get answers too. Thank you. I hope you keep making these videos!!!
Glad I could help!
Excellent, excellent video. Here's someone who knows how to teach. THANK YOU!
Glad it was helpful!
At last, a clear explanation without waffle or repetition.
Thank you. 🏆
Glad it was helpful!
Thank you sir; you have explained the subject in clear and easy to understand manner.
You are most welcome
this video is gold!!! thank you so much, i cant descirbe how much useful infomation i have learn in these short 30 min.
Thank you
Thanks for watching.
broken it down makes it seem so user-friendly and easy to use. I can’t wait to start making soft! Thanks again!
You are so welcome!
you are honestly the best. Thank you for all of the videos.
Glad you like them!
I just took my 10 year old PC apart (knowing part of the content in this video) and put it all back together with a new CPU cooler (yes, it works). This video explained so much of what I learned. I probably should have watched it before I pulled cables but I still learned a lot by watching it after.
Thanks, glad we could help. Hope your new cooler is working well.
I've seen many explanations of how to connect plugs to a MB, but this is absolutely the best.
Glad it helped
FINALY …A DETAILED VIDEO THAT EXPLAINS IT WITH SIMPLICITY!! THANK YOU SOOO VERY MUCH! Brings the fun back into it instead of the painful frustration! 😉 😁😁🍎❤️
You're welcome!
TH-cam is like an old library with a shiny new front sitting with thousands of classics in back...Most of the time one just enters the shiny new front and thats enough...But sometimes to solve mysteries and find the truth one needs to go past the front in the old classic section...And when one does that you see the real value of the library...Today i stepped into the classic section to satisfy my urge of digging deep...And i find this video...Congratulations and keep enriching the classic section of TH-cam where the deep mysteries will be solved in present and future...
This is one of the most practical and informative knowledge base educational videos made by this gentleman. Those who claimed themself a PC builders in theory are just putting those parts together like the old days when we jigsawed those toy model cars that came with a small battery motor. They are not building anything at all! Very few to none that explain how the technical part works nor where the electrical wire should go and how it works.
Thanks, glad you liked the video.
Everyone gangsta until they have to do cabling
The pain of a new builder
Frrrr
Very informational video deserves a like and subscribe. I would love to see more content from this channel❤️
Thanks for the sub!
Thank you so much. Precise, clear and easy to understand.
Glad it was helpful!
A good indicator of one's mastery of a particular subject is how simple they can make it for others to learn. This person obviously knows his stuff
Thanks, glad you liked the video.
Excellent the most informative easy to understand video I’ve ever seen. Well done I wish they were all this good 👍
Glad you enjoyed it!
amazing video i was really worried to not being able to build my own pc but this video is gold and gave me the confidence, keep up the good work
Glad I could help
Fantastic video. Very informative and the information is conveyed in a way that makes is very understandable.

I don't mind watching a video this long, if it is this good
Glad you liked it.
I made the mistake to not plug the P4 connector. Thanks to this Video I was able to figure this out. Awesome.
Glad it helped
great technical video with enough descriptions
Thanks, glad you liked the video.
Thank you.Very useful and very well explained 👍👍👍👍👍👍👍👍👍
Really great series thank you so much for this information 🔥🔥do not stop
Thanks for watching.
This gives me vibes of being in university back in 2005 and watching a video from the 90's, yet it's a new video with modern information, I love it haha! Thank you for this video!
Yea, I know what you mean. This course will be the last to use this format. New course after this is using a new format and will be in 4k.
@@itfreetraining I personally really enjoyed it, nostalgic feeling yet with new stuff, but I know not everyone might like it, thanks again! It was very helpful and you guys are part of the reason I am sitting here typing on my half new PC :D Good luck with all your courses, I'll subscribe to you, you never know what you'd need in the future!
Finally! I found a video that clearly illustrates and explains motherboard connectors/connections. I'd like to ask though, is it possible to wire a two prong toggle switch between that that 24 pin cable and PSU?
Glad you liked the video.
I am not sure what you are asking. It is possible to buy cables or adapters which allow two PSU to be used together on the same computer. This is generally used for mining. I have used one before and they work quite well. You can see an example of one here.
www.scorptec.com.au/product/power-supplies/accessories/69884-ac-005-cnonan-p1
I have not used one before, but there are some power supplies that support two computes. They are rare and possibly the only the company that makes it. I could be wrong.
www.phanteksusa.com/products/phanteks-revolt-x-power-supply?variant=12550351257655
What is a "two prong toggle switch"? Never heard of such a thing in my life. and this switch goes in between the 24 pin cable and the PSU? That doesn't sound safe.
Or were you referring to an adapter with dual 24 pin headers that can power dual systems?
@@angrysocialjusticewarrior a two prong toggle switch is basically a toggle switch with two contact points only. I call it that because that's what I saw.
I'm thinking of cutting the green ps_on cable from the 24 pin power cable and putting a toggle switch in between. I have no idea if that's okay.
@@vedeledev I know what you are referring to now. If you have a look at the following video it will explain which wires you need to use. th-cam.com/video/QvIVtmFq2cw/w-d-xo.html
It would be possible to add a power switch to a PSU. You can also purchase an adapter to do this. See below.

It's highly educational! I really learned a lot. Thank you very much, sir.
Glad it was helpful!
ifreetraining: well done, you pitched this at the perfect level (at least for me)!

This is the greatest video for beginners EVER MADE. Thank you!
Thanks very much.
Why was i so lucky to find this video.
Thanks for watching.
learned a few things I was not sure about while in the process of DIY my new rig, many thanks to you for the awesome video 🐱👓🍁🙋♂️
Glad we could help.
Best video ever about motherboard connectors, thank you :)
You're welcome!
Great video, wish I had watched it before my last build.
Thanks glad we could help.
Wow thanks so much! I thought it will be boring but you said lot of useful information so it was fun to watch
Glad you enjoyed it!
Thank you. I don't have to purchase another Power Supply. You saved my ass.
Glad we could help.
Great information. Thank you!
Thanks for watching.
Superb explanation ,I loved it👍
Thanks very much.
Great video, thanks for taking out time to do this
Glad it was helpful!
8:40 Mini Molex connectors are still useful for powering mini converter cards. For example, I have cards that allow Compact Flash cards to be attached to the motherboard to act as a HDD, which is faster than mechanical drives and can replace old IDE drives at a lower cost.
I found it "2.5" Drive Bay IDE to CF Adapter Card". Thanks for pointing this out. I will keep it in mind for future videos.
Excellent video, perfect presentation !
Thank you very much!
I wish i had seen this video before building my own pc, it would have saved me A LOT of worriing and helped me out a lot. Still made it first try though.
This video is pure gold, may a bit dry but still awesome
Glad I could help!
Very well put together video. I enjoyed it. Looking forward to your next video. :)
Glad you enjoyed it!
You people are my kind of people let's make you money! Ford once said The Industrial, adapted to his quotes, kept them in business, gave away my product, and sold my parts. The idea is to make it idiot proof! When people build replacement parts, Andrei sell hobby parts me I just want to say I built mine and it looks different thank you for allowing me to view this I believe in helping one another thanks there's money in your direction you already know that I hope gave different ways to generate funds the next is making it so people without credit cards purchases is hard so many ways to get me hooked I liked the wire harnesses and parts ty
#NT49 thank u sir for all visual presentations & for loud n clear explaining.
So nice of you
Helping a ton on my first pc build thankfully there's vida like this

I actually learned a lot! Great video.
Awesome! Thank you!
Excellent overview!
Thank you.
Great videos brother!
Appreciate it!
I finally understand the cables I seriously was struggling. I feel better now.
Glad we could help.
Great use of photos, thank you so much!! My professor gives us text to read, told us the book is optional. So we have no idea where it corresponds in the book, according to his syllabus, gee thanks. His CompTIA pdf's don't have all the connectors listed! (former teacher here, his assignments drive me crazy and cause me extra hours of research because he's not providing thorough resources, or resources that even match what he expects us to know and troubleshoot and apply.)
Definitely going to save this one for later and watch it all the way through. Tonight, I'm just trying to get this assignment done. Ugh.
Thanks again!
Glad we could help. There is a pdf download in the description if you wish to download it.

Hi there, great video and straight to the point, clear and concise method of instruction. However I do have a query about standard front USB and AUDIO case panels used in conjunction with (Ahem) Dell motherboards? Pinouts are impossible to find as I get an error on boot up and have to press F1 to start every time. I could stop the error message in BIOS, but is just one of those niggling things; like an itch on my back that I just cant quite get! Any Ideas?? your help would be much appreciated. Thanks
Outstanding!
Thank you kindly!
