Hey, everyone! I know much of what is said in this video isn't news to many of you - but as the PC gaming industry expands, new builders will flock to videos like these. I really wish I had a guide like this one when building my first PC. Wiring things up was confusing! But much like anything else, practice makes (almost) perfect. Thanks for watching!

I took apart my computer to clean it the other day, and when putting all my components back together, it wouldn’t turn on. After 10 minutes of confusion, the 24pin wasn’t connected....

I really enjoy the newer videos you're putting up that cover more of the basics. As someone who is going to be building their 2nd build (1st was built around 4 years ago), these videos really help me back up to speed!

I'm surprised you haven't called these types of videos " learning with Greg" it's got a nice ring to it This is genuinely helpful

Very nice video. I've been looking through a lot of PSU vids and this one is the only one that's quality, tasteful, interesting, not SUPER LONG, and covers everything that needs to be covered concisely. Thank you

Thank you Mr Saladbar, your discord people will never forget.

Additional info (you'll almost certainly never run into these cases) 3:00 Most motherboards will run just fine without the extra 4 pins. If your power supply only has a 20 pin ATX connector, it should still run fine, however, don't try super intense overclocking or installing to many PCIe cards as the motherboard has to handle up to 75W of power per PCIe card. 4:40 Some low end motherboards may have only a 4 pin EPS connector. If your power supply only comes with an 8 pin that is not splittable, you can still plug in the connector as is with the extra 4 pins hanging off the side. As long as your orientation is correct (latch matching the notch), then it won't matter which side is hanging off the side. 5:55 especially beware of the single 6 pin to dual 8 pin adapter. You don't want your wires melting. If you desperately need to use an adapter, use them to convert to either a SINGLE PCIe 6 pin or a SINGLE EPS 4 pin at the max with a LOW POWER CPU . Molex is rated for 132W on the 12V, while PCIe 6 pin is 75W, and EPS 4 pin is 155W. No overclocking or possibly turbo boosting on these adapters. On the topic of adapters. Technically, if you have an extra 8 pin EPS connector, you can re-pin it to be a PCIE 6 pin, or 8 pin with some soldering as they are both just 12V and grounds (I've done this once), but seriously don't do this unless you know what you're doing. 7:50 The quality of molex connectors has reduced overtime as manufacturers have become cheaper with making them. Be careful not to plug them in upside-down with especially low quality molex connectors (yes they are shaped unsymmetrically, but the plastic can be that low quality on some parts) Some power supplies may also come with a small 4 pin connector. This is used for floppy drives and is a mostly dead connector at this point. You can basically ignore it.

Great info. I would just add that modular power supply cables should be kept together with their respective power supply. Cables generally are not compatible between manufacturers even if they slot into each other, so avoid taking the shortcut of changing the power supply only while still using the same cables should you need to change. Custom cables are manufacturer specific then as well.

Thank you so much. I literally had a breakdown over these cables and this video saved me

G'day Greg, It is great you are doing content with proper information to include beginner builders into the Hobby & give them the confidence to build themselves, as someone who has been building PC since the '90s seeing a good 'How To...' or 'Explaining...' video to help newcomers is always welcomed, especially considering how many 'Bad Cough The Verge Cough' ones get uploaded

Greg, thank you so much for putting out this video and explaining the power connections for a power supply in a very thorough yet simplified manner. I appreciate you man 🙏

Great video. As a new builder I would have loved this! Had to learn the slow and personal way, since most “build guides” don’t really go into wiring too much

Looking to build my first pc this summer if parts are in stock. These videos are incredibly helpful, thanks so much !

Thanks, sir. My son and I weren't building a gaming machine, merely trying to examine the power supply of an old PC, but you told us so much of what we needed to know.

I've been doing this for 30 years yet I still learned something. Great video!

Again, GREAT timing with this video. Forwarded to some friends who are currently building their first PC ever. Good video!

Third time's the charm. This was really helpful to me as you focused on where the cables should be going in, others had covered it but you made it crystal clear. I now feel confident enough to try swapping out my PSU, thank-you!

After hours of having trouble and searching the web this is the easiest and most helpful by far! Thank you for this video it made my life a whole lot easier 😊

Think more videos like this are needed. Some people who want to get started but might be timid about asking more experienced people questions. Good video.

Thank you so much for this video, idk why but i was actually shaking i was so nervous building my pc, and you made the psu part so much easier then i was making it out to be. Id still be on a 500 watt 1060 build if it werent for this vid. Now im on a 30 series build and LOVING it. Much love brother.

Very helpful as I'm starting out fresh to the PC world so a basic understanding of these was needed, Thank you!!

Very helpful while I was building my own rig. Thank you for the advice!

This morning i ordered some of the Premium sleeved cables for my corsair RM 850 and you make a video the same day about PSU cables :o

Upgrading my rig and saw this 8pin and 4pin CPU plugs. I scratched my head cause I haven’t seen this before but it has been 5-6 years since I’ve built my PC. You answered my question and saved me from buying a new power supply. Cheers 🥂

This was exactly the info I needed, thank you!

I appreciate you. I hope you know that you helped so many beginners more than you would know:)

Damn Greg. I know an older video, but every time I have a question it never fails to search your videos on here. Thank you!

Great video which gives a clear presentation on plenty of cables, very appreciated.

I needed this like 3 months ago.... glad it’s here now for future builders

Once again you upload a video the day I needed it lol. I swapped graphics cards and power supply’s from mine and my cousins system and their motherboard had a 4+8 cpu power connector but the power supply only had an 8 pin so I wasn’t sure if I could use the power supply but now I know it’s fine. Thanks!

Molex used to be the state of the art in electronics from about the 1940's up to 1980 - at least. They were electrically/physically very rugged, expensive, and almost never the cause of a bad connection. The only thing that got rid of them was the high tech in designing plugging "keys". Now we have so many keyed choices that can endlessly prevent a wrong hookup, no matter how many cables you have.

Its always that tentacle monster hissing at me

Just what I was looking for, someone to explain the weird 8 pin & extra 4 pin ATX1 & ATX2 CPU PSU connectors. Thanks very much for making this video.

Great informative video as always Greg!

This got uploaded on the day of me building (well, struggling to build) my first pc. Thank you sir, you are a gent and a scholar.

Currently watching this before connecting my PSU, I have more of an idea of what to do. Thank you!

Greate video. Came in use when figuring out what connectors do what!

Thanks Greg now I finally understand everything about the cables

Thanks so much for making this brilliant video! Your advice about 4 pin vs 8 pin CPU power is invaluable. Checking the motherboard I'm planing on buying (a Gigabyte Z790 UD), it has to eight pin ATX plugs. That wasn't expected. Now I have to make sure my proposed power supply will work with it.

Looking to forward to my first PC build, this is very helpful. Thanks

Thanks for the info, it's greatly appreciated.

Thanks, only had old machines so great to get prepared for the 21st century on this weekend's build.

My first time building a pc was a bit nerve racking because of the pci e and cpu cables looking similar but the way they split gives you an idea which is which. Very helpful video

You are the best of all trying to explain Power supply...And you speak very very well. )no Ugh between each word)

Thank you for this. Build coming up shortly

Thank you. I appreciate the knowledge you taught

This video is really really good for entry level pc guys like me. Thank you Greg.

Thank you for your time and video!

This was great Greg. I have now built a number of systems & made a massive blunder the other day by not connecting the modular 24 pin MOBO cable correctly into my PSU & thinking the PSU was dead. Long story short, $400 AUD later mind you, I discovered it was not dead & did not need to replace it as I connected the MOBO cable the wrong way around (PSU side in the MOBO & the MOBO into the PSU). Can I suggest a video showing how to connect modular cables to a PSU would be useful, as they are becoming more cost effective & more people are using them to avoid clutter in their cases. Otherwise, keep up the great work you do 🙂

Very nice to learn the basics indeed. I have build (i have made my friend build, but i watched!) computers several times, but i never knew about the 8 pin and 16 pin CPU thing .. and that you can attach 8 pins to a 16 pin CPU motherboard and it works. Had we known that .. we would not have bought a new PSU recently because the old one only had a single (split) 8 pin connector .. and now i had to buy a fairly expensive new PSU with 2x 8 pins (for nothing as it seems) ... ... the joys of 2020 building a home office

THANK YOU SO MUCH I have been confused for a long time

Thank you so much! This video helped me so much.

Very helpful, much appreciated! Thank you.

This was super helpful! Thank you!

yess!! i needed this !! thank you so much!!!

Very very clear...thanks a lot for this video

I LOVE THIS VIDEO. Finally someone talk about this

all the info i needed ty

I know is too late, your video is over a year old, but you safe my computer. Thank you so much.

very helpful.. thanks a bunch greg

I just upgraded my MoBo to one that gives the option for 8+8 and i knew that i could just run a single 8pin, but i wanted to clarify that i couldn't use a Pcie 8pin. and as i predicted i cannot, thanks for the clarification Greg. you make information so easily attainable in videos like this.

thanks i was wondering if i could just use my old psu that only has a four pin while i waited for my new one to arrive. you earned a subscriber and keep up the good work!

The video is great! :) Thank you!

Many thanks for this video, it "put things in their proper place" - appreciated

amazing video for a beginner like me. Thank you!

I already know most of this, but always nice to learn a thing or two!

Very useful, I will need these tomorrow when I will instal a new Corsair power supply.

Literally the only video that helped me. Thanks

Appreciate the help at 4:44 with PCIe cables

that's the stuff i was looking for. thanks man you saved me

went with EVGA 500w for my first build - great price & thanks to this video , watching it again now with PSU in hands ready to connect

It's an elementary concept, but I can't tell you how much I would have appreciated having a simple short video like this when assembling my first PC 6 years ago. "Line up the plugs" isn't always useful advice when power supply pins all look very similar to the untrained eye.

Thanks man, learned new things.

Literally installing a new PSU and tower cooler while watching this. Nice timing!

Very informative, many thanks.

Thanks this was super helpful

Very helpful. thanks.

SUPER helpful as my 14 year old and I build their first computer (me knowing absolutely nothing starting out!) Thanks!!

Thank you for great video!

Fantastic video, really helped me, thank you

Thanks! Haven't done this in 10+ years and didn't know about the 4 or 8 pin

Thanks! Super helpful. I'm in the midst of building my first PC and I was so confused with the GPU cables having extra connections daisy-chained to them, it all makes much more sense now.

Awesome! Very well explained.

Really informative, thanks man

"thanks for learning with me" - wow that's the first time I've heard that, and I like it, thanks for the video!

genuinely understandable thank you

Very useful vid Greg, thanks !

Totally appreciate this! I am a newb at building PCs. I wanted to switch out my 8 pin GPU for a 16 and unsure if I needed two separate cords or can use a single cord that has two 8 pin connectors

4:04 lol that would have been nice to know before, this is an amazing video man

Really helpful video. Thanks bro

I needed this vid 3 days ago

Fantastic content. Thank you!

Good run down, thanks for the info.

This video is super informative, I wast thinking why rog strix x570 e gaming have 4 ping capu cable and 8 pin… not I know it’s your choice which pin to use

Thank you for this video.

Really thank you I didn’t know what to do

Thx you're video where vlear and showed me every step making it so muche easier

excellent video, thank you

Thank you your video really help me. First time pc builder.

Thank you sir 🙏🙏🙏. Only needed this video 🙏
