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!
u should do a video on fans mounting and connections 3pin vs 4 pin and how to do fan curves. and what to connect to CHA_FAN and CPU_FAN, CPU_OPT etc maybe even positive vs negative pressure too
thank u for your sacrifice
We're all astonished by your knowledge.
But for the newbie
What you're saying is overkill.
The wattages the power consumption newbies don't care they just want to know where to put the cables at.
All of your fans wish you could talk just a little bit faster.
Lol
Greg, silly question if you plugged the PCIE cable into where a cpu cable would be, what would happen?
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've been building computers for half my life and I Still forget to connect the 4+4 from time to time and freak out for a second why it won't boot.
Im currently having the exakt same problem. But the 24pin is connected. I just know jack shit about computers
@@fjoddmaster9375 did you figure it out
Lol
@@fjoddmaster9375 very few things cause PCs not to turn on. ram not in properly, cpu not in properly, you didn't flip the power switch on the power supply, you didn't hook up the power button on your case to the motherboard right or your graphics card is short circuted, aka dead. These things will prevent your PC turning on. All easy to find out.
Thank you Mr Saladbar, your discord people will never forget.
I like that Mr salad bar that's a good one.
Lol
For a newbie computer builder Mr salad bar is going Overkill.
Newbies don't care about the wattage the volts the wire gauge.
They just want to know where do I put these wires at.
@@KTHKUHNKK it does help to know though, I ran into a voltage issue with one of my Power supplies, good to know your voltage when you need to.
@@KTHKUHNKK I mean it’s in the title, he is also explaining each cable if you only need to see where to plug them in go watch a “All power supply cable types” not “All power supply cable types EXPLAINED”
@@cjrisener241 Glad you guys liked the comment, it's from the tech yes city discord when the mods and admins and a large portion of the user base changed there names or were changed to Greg Saladbar. It was quite funny.
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
I've been working with PSUs since before they had any of these connectors... I just like hearing him talk XD and seeing if Pepsi shows up
@@DoctorX17 i wish i knew you irl this shit is so stressful
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.
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 so much. I literally had a breakdown over these cables and this video saved me
I needed this like 3 months ago.... glad it’s here now for future builders
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 🙏
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
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!
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 😊
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.
The declining quality of Molex connectors has always been a problem; the actual Molex company did (and does) make them in high quality but the clones cut costs. For example, the power supply connectors for the old AT boards were supposed to be keyed but they got less so over time as PC clones progressively cut costs. At first you could connect them incorrectly but it would require force and it would look wrong as the keys bulged out of the socket. By the time ATX came out, new builders had to rely on the community shouting "BLACK TO BLACK!!!!" at them to not connect them backwards lest they melt the PC since there really weren't meaningful hints by then. Early on the four pin connector everyone calls "Molex" and the more compact version most commonly used with 3.5" floppy drives had a death grip but later clone manufactures were loose enough to fall out on their own. Also, once upon a time you could yank them out by the cables, but try that these days and you'll likely rip the wires out of the socket with hardly any force, especially with adapters, e.g. for fans or hard drives.
@Jovica Jevtic Yeah. The +2 is usually detached but if it isn't it's fine to hang off the side.
So I can just use another 8pin to fill the extra 4pin on my MB? Mine has an 8pin and 4pin in the top left.
@@fubsthefish8320 If it's an 8-pin CPU cable, yes. The extra 4 pins can just hang off the side if the plug doesn't separate. That said you'd need the CPU to pull in the 250-300 watt range or higher in order for the extra connector to be relevant.
@@dycedargselderbrother5353 I do understand I don't need it. But I've seen that some MBs don't boot without it and I wanted to make sure just using 4 pins of the other 8 pin cpu cable would work if required. Thanks brother.
Thank you for this video! I have a general good knowledge of PC tech and hardware, but only build a PC realistically every 4 or 5 years. Every time there's inevitably something that I forgot what it's for or if it's compatible with this that or the third, or something new that I may not have paid much attention to because it didn't apply to me. So videos like this really do help! Thanks!
Again, GREAT timing with this video. Forwarded to some friends who are currently building their first PC ever. Good video!
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.
Thanks, Adrian!
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!
How did it worked out? I'm about to replace my PSU as my old one has a fan bearing failure and I'm quite nervous as I've never installed a PSU by myself.
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.
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 🥂
Very helpful while I was building my own rig. Thank you for the advice!
Very helpful as I'm starting out fresh to the PC world so a basic understanding of these was needed, Thank you!!
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
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.
I appreciate you. I hope you know that you helped so many beginners more than you would know:)
Great video which gives a clear presentation on plenty of cables, very appreciated.
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.
This was exactly the info I needed, thank you!
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!
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!
Great informative video as always Greg!
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.
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.
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 🙂
This video is really really good for entry level pc guys like me. Thank you Greg.
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
Currently watching this before connecting my PSU, I have more of an idea of what to do. Thank you!
Very helpful, much appreciated! Thank you.
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.
🥵🥵🥵
You are a menace @@itisfreak
Looking to forward to my first PC build, this is very helpful. Thanks
Thank you. I appreciate the knowledge you taught
Thanks Greg now I finally understand everything about the cables
Greate video. Came in use when figuring out what connectors do what!
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!
Can a motherboard be having some sensors showing 90C if the 4 pin power is not connected to it? Only the 8 pin one. Cause In HWMonitor I have a sensor called TIMPIN4 like and is always 88C or 90C while the others sensors are 30C and mobo is like27C, is a Strix B550-E with 5800X3D cpu. Thx for info.
Thanks man, learned new things.
Thank you for this. Build coming up shortly
Could you use only daisy chained (pigtailed) part of pcie(6+2) cable for powering gpu or do you strictly have to use first part of that cable? And what is the difference?
You are the best of all trying to explain Power supply...And you speak very very well. )no Ugh between each word)
Thanks for the info, it's greatly appreciated.
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
Thanks for this video and the info. I have a Dell Inspiron 3650 and its mainboard power connector is an 8-pin. Can I use a PSU's 8-pin PCI cable for it? Or do I need a 20-pin to 8-pin adapter ( I know your video discourages this)? I just can't find any PSU with a mainboard cable that's 8-pin other than the OEM style 240w PSU.
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.
I know is too late, your video is over a year old, but you safe my computer. Thank you so much.
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.
I’m new to this, really wanting to upgrade my psu, so is it plug n play as long Ila’s I go with same brand or will I run into trouble of it not recognizing the new psu or working with my current configuration?
You missed a golden opportunity to say 'Thanks for powering on with us.'
I would cringe
Thats cringe
Cringe

@@venividivici4253 Being late to the party by three weeks is pretty cringe.
Thank you for your time and video!
Very useful, I will need these tomorrow when I will instal a new Corsair power supply.
Thanks, only had old machines so great to get prepared for the 21st century on this weekend's build.
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
I LOVE THIS VIDEO. Finally someone talk about this
Many thanks for this video, it "put things in their proper place" - appreciated
very helpful.. thanks a bunch greg
Thank you so much! This video helped me so much.
This was super helpful! Thank you!
SUPER helpful as my 14 year old and I build their first computer (me knowing absolutely nothing starting out!) Thanks!!
I already know most of this, but always nice to learn a thing or two!
I already knew all of this, I just like hearing what he has to say anyway XD
This is actually the video I'm looking for as first time PC builder. Brief explanation of what the cables do and where to connect them. Addressing the paranoia of connecting incorrect lines resulting to parts failure. Thanks brother
So upgrade after upgrade I've kept my PSU from my first PC build that I built like 5-6 years ago. It IS a platinum 80+ 1000 watt unit (this is back when I thought I might SLI but never did) So its not like my builds have ever really demanded TOO much from it (no overclocking and no multiple cards or anything). Should I get a new PSU whenever I do my next major overhaul or do these tend to last a pretty good amount of time?
Literally installing a new PSU and tower cooler while watching this. Nice timing!
yess!! i needed this !! thank you so much!!!
Very very clear...thanks a lot for this video
hi greg i have got a Z400 AND CAN i connect a Z440 PSU to it .what are tge D1 D3 Cables labelled for should i match them as per the labels in the motherboard n drives
amazing video for a beginner like me. Thank you!
Great content dawg, yesterday i built my first one, The psu did not contain the plus 4 pins for the CPU and i thought that it is a problem and i could not fimd solution to connect those 4 pins. Does not a 600W psu should contain those additional 4 pins for CPU?
Literally the only video that helped me. Thanks
that's the stuff i was looking for. thanks man you saved me
My 6950xt requires 2 8 pin connectors. Should i run 2 8 pin connectors from the power supply or just use 1 cable with the additional pigtailed 8 pin connector ??
This had att the information i required. I question the daisy chaining pcie cables, isn’t there a chance of exceeding the 12.5A 150 watt pcie connector max per cable limit for 7900 and 4090 graphics cards? My 7900 has two sockets, wouldn’t it be less stressful to have the power delivered to each socket from a separate cable instead if a daisy chain?
Does all PSU have same pin out configurations? Can I use PCIE cable came with EVGA on Cool master PSU? Referring to modular PSU
all the info i needed ty
So, I'm shopping for a new apu build ad the micro ATx has 8 pin CPU and 4 pin CPU connector on MB but not sure which to use for the 4 pin and it needs the 8 also
Appreciate the help at 4:44 with PCIe cables
Hi. Great video. I am in the process of rebuilding an aurora r12 and added 2 fans and I want to power 2 fan hubs off of a molex x3 cable. The problem is with the dell 1000w psu, it is all numbered with r1 through r16. R7-r9 are cpu/mb and r10-r12 are hdd/odd. These are the only that fit the molex as r1-r6 don't fit. Where do I plug molex for power? Ps. The fan hubs are molex and have 4 pin pwm that connect to the mobo. I can't connect straight to mobo without molex as my fans are practically server fans and I do not want to fry the mobo. Thank you for any info you can provide. Dell psu model D1000EGM-00
Hi my old psu is silverstone 550w, i just bought msi v450m motherboard. My old psu has 4 pin connector and the new motherboard has 8 pin connector.
So i can use the 4 pin connector to power up 8 pin connector on the motherboard? Or should i buy and adapter or buy new psu?
I have an old GTX 460 gpu (will be upgrading soon now that prices are dropping) which requires two 6 pins. Can I use the daisy chain on a 6pin for both or do I need to run two separate 6pin cables?
I needed this vid 3 days ago
Hi. So i recently put together a build but i am waiting for monitor to see if it will boot. *fingers crossed* Anyhow when I connected my 3.5 hdd the cable which is connected to it (not the sata) it has multle connections.. does this mean I will be able to eventually connect more 3.5 hdds to set cable which has on its end connected to psu 6pin connector? Cause I looked at how the cable is and it would make it really difficult to do so... any tips or video guide on how to possibly do this cause i have also a dvd drive and that required same cables. Thanks.
Hey I have connected the 8 cpu pin connector for additional power / extra performance should I connect the 4 pin too ?
Is there like specific screw drivers i need or do they come with the cases im ordering a nzxt case and I have no idea what screwdriver I need
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!
On Modular PSU's are the CPU and PCIE power sockets interchangeable? I have a motherboard with 8+4 CPU power, so two cables. Then I hope to get a 3080 so that's another two cables at least. My Thermaltake PSU doesn't clearly state which plugs in where.
Very informative, many thanks.
My Job is building computers and I still need this video
