All Power Supply Cable Types EXPLAINED

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....

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

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 <3

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!

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

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

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

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.

Its always that tentacle monster hissing at me

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 🙏

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

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

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.

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

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

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.

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!
