Believe me or not it dose add system stability when you connect the 2nd 4 or 8pin power cable as it actually helped me in my recent build because i kept having soft locking a crashing issues on a gigabyte x670 with a 7700x ocd and undervolted at 5.3Ghz with 32gb of corsair ram also had those downclocked from 6200 cl38 to 6000mhz cl32 for the best performance on amd plus all the sub timings also optimized.
So this processor's max boost clock is 5.4 while stock is 4.5 and you locked it to 5.3? Looks like you technically OC'd it, which is exactly the case for when you might need that extra power. Also you didn't change your RAM speed at all, as you've decreased your clock speed, but also did so for the latency. I'd say now that you've got that extra connection, it's best for you to return everything back to factory settings as you might see a tiny FPS jump, albeit bit more power used by CPU when demanded, compensated by lower usage when idling.
Hopefully you see this bec i amz noobz. i can just use another cord to plug in the 4pin right? I have an 8 pin plugged in but to get that second 4 pin i had to plug another plug into the psu to motherboard.
Small correction, according to techpowerup, the 13900k does 287W at the connector, which is still within the limits of the 8 pin so you're fine. But if you do remove the power limit it can go up to 373W and 413W overclocked on a watercooling, so it's not just extreme overclocking, regular oc will hit it. (Though you'd probably be fine doing it for like 30 min for a big e-peen score if you have airflow over it.)
I always use the extra connector for stability. High end cpus will draw off that and helps to split the voltage so you don’t get a BSOD. it’s not just for looks or overclocking.
i agree, my desktop was randomly crashing without BSODs due to the SSDs being ejected randomly, i tried to fix it for months untill i plugged in that extra cable and my pc never crashed again.

just because you don't need it, does not mean you shouldn't use it. I've seen systems refuse to boot without it and as soon as you add the extra 4-pin 12v ATX connector it works. So, I ere on the side of caution with this one.
I have the exact mobo shown in this video - refuses to boot without the 4-pin also connected despite what the manual says. Guy in video knows jack shit about what he's talking about
My aging Gigabyte motherboard will run without it. For a while. Then the issues start that quckly lead to a crash. Smooth sailing and better performance from the outset with it connected.
For anyone browsing the comments in disbelief: I have a Ryzen 3900X build, only one 8pin is connected. I have two 8pin slots available in the mobo. I have a Ryzen 5600x build with an 8pin and 4pin connector, only the 8pin is connected.
Did you actually have stability issues before plugging it in? I'm curious since even a heavily overclocked 11700k should barely increase voltage drop across those cables
You're not going to need the extra pins with an 11700k, even if you overclock it til it burns up. 11700k doesn't draw enough amperage that the extra 4 pins make a difference. Your power supply is still going to be sending all the extra needed power through the 8 pins. The only time the additional 4 is useful is if you're literally sending over so much power that the connectors are beginning to heat up to the point where they become resistant and can no longer supply power. Not going to happen with an 11700k
He roasted us while being a little ignorant and wrong. Most high end (and many mid range) motherboards WILL ignore Intels 253 limit by default and set their own higher limits. For the 14900k they will draw up to 400 Watts.
My first time of using 750W, I tried to find that 4 pin in my PSU also, but I figured out that the 8 pin can split in half to the 4 pin. Dam, what a design 😂
Also take into consideration every other component on the board can draw power stuff like the nvme drives, pcie slots, wifi, Bluetooth so much more stuff draws power. Also your pcie slots can deliver quite a bit of power to your gpu also. It’s not just needed for extreme oc, it’s helpful in many other scenarios too. It’s just best to plug it in if you’re going to use over that amount of power but in most scenarios I can come up with you could use it for sure.
your gpu pulls 75watts from the slot, your nvme pulls nearly nothing, bluetooth draws nearly nothing. wifi draws nearly nothing in power. Literally the only meaningful load on your system is the CPU and GPU. Most sockets are more than capable of feeding 220+ watts to the cpu. Plugging in an extra 12v cpu connector is NOT going to make the rest of the system have more power available. There's literally not much use to using it unless you're pulling massive wattage through your CPU. And most people don't even saturate what the socket itself is capable of, let alone the 8pin that can provide 300+ of juice to the cpu.
Those connectors are called CPU connectors for a reason... They're not used for other things... It's the 24 pin connector that supplies the 3.3V, 5V and 12V lines to the motherboard. Other components could also have separate power connectors like the PCI connectors supplying power to gpus or the SATA power connectors for well sata devices and the good old MOLEX connector for very old things.
@@marcasrealaccountbro my mobo has 8+4 pin .and i connected to 8+4 my cpu is 13400. My other 4 pin snake like wire stuck on my fans so i was thinking plug out 4 pin. Is it ok??
My Z690 MSI board (not even a super fancy one, just the Tomahawk) has 2x8pin connectors up there. Dude is 100% correct - at least according to MSI themselves. Since my then current PSU didn't have a second 8 pin plug, I mailed support and they told me the same thing. One 8-pin can provide well over 300 Watts, so, unless you're going to break out the liquid nitrogen before every gaming session, there's no need to ever plug anything into that second 8-pin socket.
Facts, mine wanted both plugged in. If it needs the power it’s there. I mean mine is loaded every slot, 3 M.2, gpu takes 75watts from the MB. Fans are powered off board.
I'm using all 16 pins just to make it looks good, one of the extension cable isn't even plugged in to the PSU 😂 The same reason why some people populate all of the ram slots
The MSI unity second 8 pin connector power the PCI lanes and other voltage needs of the motherboard, so it all doesn't have to be pulled through the 24 pin. And putting the load over 2 cables instead of one has a more consistent and less strained power draw specially on higher-end CPUs
Please don't get people wrong, the 8pin socket is not a high overcurrent capability. 240W is usually the limit of 8p, and 144W is the limit in safe state. Limited by the connector, it is standard for each pair of positive and negative poles to carry 3A current. Each pair of cables carrying 5A will produce a significant temperature increase. If you are using a top-end CPU without overclocking, 8pin is usually enough to handle all the current. But if you want a system that is more reliable, more stable, with lower temperature rise and slower wire aging. Please fill the power supply interface as fully as possible.
Even the 4 pin alone can supply 192 watts. I'm surprised most people don't know you can plug the 4 pin into the 8 pin (on the correct position). Mind you it feels really wrong doing but it's perfectly fine.
Yep, msot of my builds have only had a 4-pin for CPU power and they're all fine. The 5800X3D I've got now is never going to draw even close to what a 4 pin can provide edit: nvm I'm an idiot I just checked through my side panel and I've got all 8 pins populated. Must have confused it with my sister's PC I built recently
I remembered my old power supply had a 4-pin CPU power connector connected to an 8-pin CPU connector on my B560M motherboard with Intel Core i5 11400F, and still works perfectly fine.
No he is wrong the 4 pin connector This is the 4-pin connector which supplies electrical current to your CPU and is mandatory to connect in the motherboard provided you are not using the EPS12V connector which is explained below. The ATX12V 4-pin connector is used by a majority of processors be it Intel or AMD. Even the power hungry FX series by AMD requires only a 4-pin CPU connector uptil the hexa-core series. So this is more important to have in a general picture best if you have a pair of these on the PSU. You can use either
@@Mitsou44 was looking through all the comments for someone who had the slightest idea of what would really go on if you used less, or just a single 8pin. You are more or less, correct. If you're using just the 4pin, the CPU will not be able to clock as high as you would be current limited or throttled. For a chip like OP's 11400F, I think a 4pin is pretty close to minimum requirement. A very good example would be my 10850K on a single 8pin. It's capable of 5.2, but because the current motherboard it's in is an ITX with an 8pin, it'll boost between 4.8 to 4.9 and a little more, but will not actually hit 5000mhz.
This is great advice. I haven’t built a computer since 4 megs was standard and if you had 8 megs you were rich! Haha I’m confident I’ll get it done when the time comes with patience and by following videos like this. 😊🙏

I'm pretty sure the PCI-E slot draws power from the 24-pin connector (and maxes out at 75W) In general though you should check the max wattage of your components before buying an overkill PSU just to fill all of the power connectors
add it anyway it increases stability and efficiency, you have essentially more wire gauge which results in less resistance and less voltage drop under quick load changes

@@kappalul2057I've seen people suggest at least a 320mm AIO, that's what I plan to upgrade to some day.

By the way, you can plug in an 8-pin connector into a 4-pin if you don't have a dedicated 4-pin cable. Half of the 8-pin will be to the side of it but it will work. Keep in mind that these pins don't power just the CPU. Many other components need power too, such as USB devices, RAM, M.2 drives, the chipset, and up to 75W for each Pci-e device (your GPU uses up to 75W from the motherboard). For this reason, I suggest you plug in that 4-pin to ensure system stability.
Same with my 11700k. I tried to run the oc at its max of 5.0ghz, but it created too much instability, so I run it at a constant 4.9ghz with no stability issues.
True true. I'm an Overclocker and I don't even use the EXTRA 4-Pin. It's RARE. I think I've HAD to use EXTRA 4-Pin ONCE. Was Practicing with LN2 cooling solutions.
Shit man, my motherboard has 2x 8pin connectors. Good thing my power supply is like 1200w and fully modular. My graphics card also uses a fair bit of juice with 2 x 8pin and a 6pin connection on it.
the most power hungry 4090 can take up to a max of 400-600 W with bios modding. The most power hungry 13900k takes up to 260 W, so you still have plenty of extra power from ur 1200W power supply, no worries
@@M1szSnot even overclock, just on a stock setup with mobo settings like auto MCE remove all limits etc will make it throw 300+ watts My 13900ks at stock auto before tuning would eat like 320-330w in cinebench, basic undervolt no other changes had it down to 260~
I already know this and still bought an overkill PSU just because it looks better with both plugged in. I mean I am even undervolted but still wanted both.
In many cases OEM "turbo" settings, that which is generally considered part of the stock experience, will benefit from having these connected. Especially if you have (a) more modern GPU(s). If you are doing heavy multitasking and playing a game in the foreground it will also become a necessity for this to be attached for general overall stability. (In my 32+ years of experience as an integrator/OEM )
Just like on GPUs, there are transient spikes that will go above the CPU’s max TDP for just a split second. Having the extra connector always for overclocking with a higher possibility of stability. There’s always more to it, never settle for the “fast tech” answer
Simply either change the power supply or check carefully if there are accidentally any additional connectors that he simply did not put or put away with the rest of the cables. If he plans to do OC, it would be good to have a better power supply for better stability, especially if he plans to use a powerful video card that will also OC.
@@MarcsSpark Reviews shows sustain power draw up to 295 under all core load. Your numbers are intel marketing info. Reviews from Gamers Nexus and tech-power showed how power-hungry is this CPU.
But those have their own cables. The cables he was talking about are just the cpu power cables. The gpu has its own 8 pin cables and for the other components there is the big 24 pin plugged into the motherboard.
The 24 pin provides the PCI-E power and can even provide cpu power if there is no dedicated connectors for it in case of very low power cpus. I have a Celeron J1800 board with no cpu power connector, only the 24pin which powers the cpu and the full length 16x PCI-E slot in which I tested a slot only powered Gtx 1650 and it worked with no issues.
The 12v EPS power also supplies power to the PCIe slots and on board devices. Yes, you are probably fine without it for most typical consumer loads, but that isn't ALWAYS the case.
I think the 5600 is better option or the x version if it somehow cheaper or if you want to go with intel then the 12400f or the non f version will be good
Get the non g version like the 5600 or 5600x.. both have more l3 cache than the g version..also get a 6700xt.. try getting them on the used market as that way your pc will be of great value
run your CPU manufacturer's tweak/configure utility from their respective website = set it to 1.2 or 1.3 volts... it will give you lots of cpu power still, but is limited so that it can't overheat/overwork itself (hard limit it can't go over). games shoulld still run great (I'm doing this at home now) GL with it
I use the extra connector for better system stability. It does serve a purpose besides extreme overclocking. Some systems might not be able to use XMP/EXPO/DOCP properly without it.
the default intel power lock is disabled on most motherboard manufacturers, if you enable MCE your 13900ks can hit 400w w/o an oc so that extra cpu 8pin is there for a reason
Shotguns need more “pellets”. Should help with the current lag issue. Lower damage per pellet to still have the total average, but adds extra chance to actually be hit by the shotgun. Also give us chokes. Wide spread, default and narrow.
MAY BE it´s enaugh to use just the big motherboard power connector. BUT its better to add also the second 8-pin! It´s mor secure. Because using both adapters means that the used/neeeded power is delivered over MORE cables - whic hmeans less amperes per cable = more secure in the manner of (cable) overheating!!
It’s not a universal truth, I’ve encountered problems with the extra connector. I used to think this so I never plugged the extra one. I got random shutdowns when the pc draw too much power too quickly, like spikes of cpu power usage. But after trying to debug it, the issue was solved by plugging it in. Engineers designing these motherboards always have a reason to put and remove stuff, don’t assume things
Some motherboards also use those extra connections to power peripherals. My motherboard lets me fast charge my phone or tablet at 60w, just need a compatible charging cable.
If you run an asus board with 13900k or 14900k. Definitely plug that in. Same with the high end x3d AMD CPUs. You will be very unstable without it on default BIOS.
I have to say this, in case of dual CPU motherboard no matter how old it is, if the motherboard came with 2 EPS power connectors, you have to plug in both of them with separated cables, or else one of the CPU might not get power and computer will not power on. I think only one 8 pin for 1 CPU is enough but it's always more comfortable to plug in both if available. Ever since there're 2 8 pin on board for 1 CPU board, I always find a way to plug in both but they are indeed can work with only one power cable plugged in. Second EPS connector only exist in at least 850W PSU so if overall you didn't have to use that size of PSU you have to content with 1 EPS connector plugged in anyway.
An 8-pin connector can deliver up to 384 watts of power,which is twice as much as a 4-pin connector. This means that an 8-pin connector can support more powerful CPUs, and provide more stability and performance. However, not all motherboards have an 8-pin socket, and not all power supplies have an 8-pin cable.
The 8 pin can usually split… on both my modular and non modular PSU, I can split the 8 pin into 2x 4 pins. *I know that’s not the point of this video, but just saying - also noticed it (the split) on the 8 pin that was shown on the video.

I know someone who thinks you only need it for a Pentium 4. The hole the size of the Grand Canyon in his logic is that I have seen connectors like that on motherboards for non Intel CPUs. In fact you can not get an Intel CPU to work on a board made for different chips. Even if you some how got it in the socket which would be just about impossible it would be immediately damaged. It would also damage the motherboard. The simple fact is that it is not just a holdover from the Pentium 4 era. I realize I might not really have to use it but I do if I have the connector on the power supply. That is of course 4 pin. If these things are hard to get to do it while you are still assembling the PC. Neglecting these things may in rarer circumstances result in a lot of pointless troubleshooting being done. If you have problems look for something loose or not connected (maybe that 4 pin connector).

on my motherboard 8 pin is connected .Do i need to connect the other 4 pin
what are the plus and minuses
thank you
just because you don't need it, does not mean you shouldn't use it. I've seen systems refuse to boot without it and as soon as you add the extra 4-pin 12v ATX connector it works.
So, I ere on the side of caution with this one.
Yes, most systems I have seen won't boot without the 4 pin
I have the exact mobo shown in this video - refuses to boot without the 4-pin also connected despite what the manual says. Guy in video knows jack shit about what he's talking about
My Asus X570 prime p can work with only 4 pin lol.
My aging Gigabyte motherboard will run without it. For a while. Then the issues start that quckly lead to a crash. Smooth sailing and better performance from the outset with it connected.

You can't push current, only pull it. That means that if you plug in the connector the CPU won't use any more power.
For anyone browsing the comments in disbelief:
I have a Ryzen 3900X build, only one 8pin is connected. I have two 8pin slots available in the mobo.

Nah fam, I plugged in the extra pins so I'd have no stability issues running my 11700k at 4.9ghz at all times when the max is 5.0ghz
Exactly 😊 use it, if your power supply have that extra cable.
Did you actually have stability issues before plugging it in? I'm curious since even a heavily overclocked 11700k should barely increase voltage drop across those cables
@lilithstenhouse267 I had them plugged in before OC. Most likely, I don't need the extra pins, but better safe than sorry
@@lilithstenhouse267 i only use Intel TVB on my 11900k, otherwise it's standard. Like @kartzzy6101 says, better safe than sorry.
You're not going to need the extra pins with an 11700k, even if you overclock it til it burns up. 11700k doesn't draw enough amperage that the extra 4 pins make a difference. Your power supply is still going to be sending all the extra needed power through the 8 pins. The only time the additional 4 is useful is if you're literally sending over so much power that the connectors are beginning to heat up to the point where they become resistant and can no longer supply power. Not going to happen with an 11700k
Naw bruh, he just casually roasted us
uhh say wallahi
He roasted us while being a little ignorant and wrong.
Most high end (and many mid range) motherboards WILL ignore Intels 253 limit by default and set their own higher limits.
For the 14900k they will draw up to 400 Watts.
My first time of using 750W, I tried to find that 4 pin in my PSU also, but I figured out that the 8 pin can split in half to the 4 pin. Dam, what a design 😂
It's because even the newest PSU has to be compatible with older motherboard (single 4 pin connector).
Yeah.... Here's a good quote for you:
"Read the directions, even if you don't follow them."
Also take into consideration every other component on the board can draw power stuff like the nvme drives, pcie slots, wifi, Bluetooth so much more stuff draws power. Also your pcie slots can deliver quite a bit of power to your gpu also. It’s not just needed for extreme oc, it’s helpful in many other scenarios too. It’s just best to plug it in if you’re going to use over that amount of power but in most scenarios I can come up with you could use it for sure.
100%
your gpu pulls 75watts from the slot, your nvme pulls nearly nothing, bluetooth draws nearly nothing. wifi draws nearly nothing in power. Literally the only meaningful load on your system is the CPU and GPU. Most sockets are more than capable of feeding 220+ watts to the cpu. Plugging in an extra 12v cpu connector is NOT going to make the rest of the system have more power available. There's literally not much use to using it unless you're pulling massive wattage through your CPU. And most people don't even saturate what the socket itself is capable of, let alone the 8pin that can provide 300+ of juice to the cpu.
Those connectors are called CPU connectors for a reason... They're not used for other things... It's the 24 pin connector that supplies the 3.3V, 5V and 12V lines to the motherboard. Other components could also have separate power connectors like the PCI connectors supplying power to gpus or the SATA power connectors for well sata devices and the good old MOLEX connector for very old things.

Imo it's a good thing xd
My Z690 MSI board (not even a super fancy one, just the Tomahawk) has 2x8pin connectors up there. Dude is 100% correct - at least according to MSI themselves. Since my then current PSU didn't have a second 8 pin plug, I mailed support and they told me the same thing. One 8-pin can provide well over 300 Watts, so, unless you're going to break out the liquid nitrogen before every gaming session, there's no need to ever plug anything into that second 8-pin socket.
Tomahawk is fancy and the most stable for AMD and Intel. For the last 5 years.
More people need to read their user manual. If your motherboard has an extra 4-pin, the manual most definitely explains its use case.
RTFM? who the F READS in the age of audiobooks and videos? LOLOLOLOL. ;)
I forgot which mobo manufacturer suggest which CPU under a certain TDP can ommit one connector.

@@1slotmech Not reading motherboard manuals are usually one of most common causes of failed builds
Facts, mine wanted both plugged in. If it needs the power it’s there. I mean mine is loaded every slot, 3 M.2, gpu takes 75watts from the MB. Fans are powered off board.

I'm using all 16 pins just to make it looks good, one of the extension cable isn't even plugged in to the PSU 😂 The same reason why some people populate all of the ram slots
8 pin connected?
Mine 8+4 pin connected but i want to plug out.
The MSI unity second 8 pin connector power the PCI lanes and other voltage needs of the motherboard, so it all doesn't have to be pulled through the 24 pin. And putting the load over 2 cables instead of one has a more consistent and less strained power draw specially on higher-end CPUs
Please don't get people wrong, the 8pin socket is not a high overcurrent capability. 240W is usually the limit of 8p, and 144W is the limit in safe state. Limited by the connector, it is standard for each pair of positive and negative poles to carry 3A current. Each pair of cables carrying 5A will produce a significant temperature increase. If you are using a top-end CPU without overclocking, 8pin is usually enough to handle all the current. But if you want a system that is more reliable, more stable, with lower temperature rise and slower wire aging. Please fill the power supply interface as fully as possible.
This is such a perfect video i was researching for hours if i need a new psu to get a proper plug for my new mobo, thank god i found this 🤙
Even the 4 pin alone can supply 192 watts. I'm surprised most people don't know you can plug the 4 pin into the 8 pin (on the correct position). Mind you it feels really wrong doing but it's perfectly fine.
Yep, msot of my builds have only had a 4-pin for CPU power and they're all fine. The 5800X3D I've got now is never going to draw even close to what a 4 pin can provide
edit: nvm I'm an idiot I just checked through my side panel and I've got all 8 pins populated. Must have confused it with my sister's PC I built recently
My mainboard has 2x4pin connectors and if I plug only 1 it's super unstable... so it doesn't matter how much it can "supply". My CPU is 65 watts.
I remembered my old power supply had a 4-pin CPU power connector connected to an 8-pin CPU connector on my B560M motherboard with Intel Core i5 11400F, and still works perfectly fine.
No he is wrong the 4 pin connector This is the 4-pin connector which supplies electrical current to your CPU and is mandatory to connect in the motherboard provided you are not using the EPS12V connector which is explained below. The ATX12V 4-pin connector is used by a majority of processors be it Intel or AMD.
Even the power hungry FX series by AMD requires only a 4-pin CPU connector uptil the hexa-core series. So this is more important to have in a general picture best if you have a pair of these on the PSU. You can use either
(I heard some motherboards limits the CPU if only 4 pin CPU power is connected)
@@Mitsou44 was looking through all the comments for someone who had the slightest idea of what would really go on if you used less, or just a single 8pin. You are more or less, correct. If you're using just the 4pin, the CPU will not be able to clock as high as you would be current limited or throttled. For a chip like OP's 11400F, I think a 4pin is pretty close to minimum requirement.
A very good example would be my 10850K on a single 8pin. It's capable of 5.2, but because the current motherboard it's in is an ITX with an 8pin, it'll boost between 4.8 to 4.9 and a little more, but will not actually hit 5000mhz.
This is great advice. I haven’t built a computer since 4 megs was standard and if you had 8 megs you were rich! Haha I’m confident I’ll get it done when the time comes with patience and by following videos like this. 😊🙏

He really roasted us at the end...
Though informative. I was pondering whether I would need to plug this in or not
Remember that power is also used on the PCIE bus. Extra cards can pull power from that connector too. If there is an empty power port fill it.
I'm pretty sure the PCI-E slot draws power from the 24-pin connector (and maxes out at 75W)
In general though you should check the max wattage of your components before buying an overkill PSU just to fill all of the power connectors
add it anyway it increases stability and efficiency, you have essentially more wire gauge which results in less resistance and less voltage drop under quick load changes
This is the real roast: more wire gauge INCREASES resistance as in how to make a short cable perform like a really long cable
Good info. You can use the 4 pin alone as well if you are using normal settings. I overclock so I use 8 pin.

By the way, you can plug in an 8-pin connector into a 4-pin if you don't have a dedicated 4-pin cable. Half of the 8-pin will be to the side of it but it will work.
Keep in mind that these pins don't power just the CPU. Many other components need power too, such as USB devices, RAM, M.2 drives, the chipset, and up to 75W for each Pci-e device (your GPU uses up to 75W from the motherboard).
For this reason, I suggest you plug in that 4-pin to ensure system stability.
You usually get an 8-pin connector that can be divided to 2 x 4 in your Powersupply package

If you do ln2 ocing there are mbs with 2 8 pins.
Some motherboards and video cards won't turn on unless all the power connectors are used.
In many cases OEM "turbo" settings, that which is generally considered part of the stock experience, will benefit from having these connected. Especially if you have (a) more modern GPU(s).
If you are doing heavy multitasking and playing a game in the foreground it will also become a necessity for this to be attached for general overall stability. (In my 32+ years of experience as an integrator/OEM
)
That was personal😭

Just like on GPUs, there are transient spikes that will go above the CPU’s max TDP for just a split second. Having the extra connector always for overclocking with a higher possibility of stability. There’s always more to it, never settle for the “fast tech” answer
Considering their PSU didn’t have the cable, it wouldn’t have the rating for such a high power cpu anyway lol
@@techheck3358 True, my comment was more about him dismissing/downplaying the abilities of that extra connector
Simply either change the power supply or check carefully if there are accidentally any additional connectors that he simply did not put or put away with the rest of the cables. If he plans to do OC, it would be good to have a better power supply for better stability, especially if he plans to use a powerful video card that will also OC.

MAY BE it´s enaugh to use just the big motherboard power connector. BUT its better to add also the second 8-pin! It´s mor secure.

Some motherboards have 8×2 Pin slots mostly on Z790 series
It’s not a universal truth, I’ve encountered problems with the extra connector.
I used to think this so I never plugged the extra one. I got random shutdowns when the pc draw too much power too quickly, like spikes of cpu power usage.
But after trying to debug it, the issue was solved by plugging it in.
Engineers designing these motherboards always have a reason to put and remove stuff, don’t assume things
Some motherboards also use those extra connections to power peripherals. My motherboard lets me fast charge my phone or tablet at 60w, just need a compatible charging cable.

When thoose cpus are using 3 times more power than your gpu... 😂😂
I have to say this, in case of dual CPU motherboard no matter how old it is, if the motherboard came with 2 EPS power connectors, you have to plug in both of them with separated cables, or else one of the CPU might not get power and computer will not power on.
I think only one 8 pin for 1 CPU is enough but it's always more comfortable to plug in both if available. Ever since there're 2 8 pin on board for 1 CPU board, I always find a way to plug in both but they are indeed can work with only one power cable plugged in. Second EPS connector only exist in at least 850W PSU so if overall you didn't have to use that size of PSU you have to content with 1 EPS connector plugged in anyway.
I watch the videos for fun because i am like “yeahh i knew all this 😎” And it helps affirm that my research was done correctly.
I had that exact "problem" when I was building my new PC and like you say, internet was saying it was just for people doing OC :D
An 8-pin connector can deliver up to 384 watts of power,which is twice as much as a 4-pin connector. This means that an 8-pin connector can support more powerful CPUs, and provide more stability and performance. However, not all motherboards have an 8-pin socket, and not all power supplies have an 8-pin cable.
The 8 pin can usually split… on both my modular and non modular PSU, I can split the 8 pin into 2x 4 pins.
*I know that’s not the point of this video, but just saying - also noticed it (the split) on the 8 pin that was shown on the video.

I know someone who thinks you only need it for a Pentium 4. The hole the size of the Grand Canyon in his logic is that I have seen connectors like that on motherboards for non Intel CPUs. In fact you can not get an Intel CPU to work on a board made for different chips. Even if you some how got it in the socket which would be just about impossible it would be immediately damaged. It would also damage the motherboard. The simple fact is that it is not just a holdover from the Pentium 4 era. I realize I might not really have to use it but I do if I have the connector on the power supply. That is of course 4 pin. If these things are hard to get to do it while you are still assembling the PC. Neglecting these things may in rarer circumstances result in a lot of pointless troubleshooting being done. If you have problems look for something loose or not connected (maybe that 4 pin connector).
