***** Even Austin himself poked fun at it. The dude is so crazy positive about the situation, it's really admirable. I'm sure as Maxime said, he'd even laugh at it!
You showed Austin because his house burned down. What I don't understand is he was laughing and smiling after he lost everything, why? I couldn't do that.
Let me give people advice, when it comes to PSU's never by cheap ones, my cheap one exploded on me when I put in my new GPU and it almost killed my whole system, luckily my motherboard saved all my parts because of it's short protection, if your PSU is sketchy replace it with something trustworthy even if it's 3x more expensive for the same wattage but it's common sense really.
looks like Austin needs to put some Ice on that burn! (I was trying to make a play on words, about Austins house burning down, and Linus making insults that burn)
I prefer single rail just for the convenience. It's a hassle if you have a large power demand and a PSU with several weak rails, because you have to strategically spread everything out or you risk your PC randomly shutting off, especially on weaker PSU's.
Phlaked Corn +1! Not only the PSU shutting down, but driving a rail close to its limit results in less efficient line regulation and filtering, and those variances and noise your hardware connected to the PSU then has to deal with it. A single rail power supply is just better. Multi-rail PSUs exist only because they cost less to produce (big magnetics and capacitors for filters are expensive!).
Washu Ken Sorry but that makes no sense. Actually a single 1000w rail is going to be better than 5 200w rails if you have 2 power hungry gpus, not like it won't work but you have to pay attention to what is connected to each rail, otherwise it may not boot or power off randomly while under load.
Phlaked Corn welp somethings cant be changed because if you have only one rail how do you connect the other to the other 6 pins? because if that doesnt work then it wont boot at all
You don't know what you are talking about. One rail does not mean one connector. It means one circuit. It means two power hungry GPU's can be connected on ANY 6 pin connector. If you have multiple rails, you cannot connect both GPUs on the same rail, because you are overloading one circuit and not using the other.
Pretty much all Multi-rail PSU's these days are actually single rail in construction internally. The over-current and short-circuit protection is typically separated into rails for safety so that no one rail/wire goes beyond a safe current range but this all ties back into a single rail for each delivered voltage. If they were not designed in this way you would not be able to combine multiple rails for more current delivery as they may not all be at the same voltage due to variations in voltage regulator chips. This is why if you read the label on a multi-rail PSU they will typically show a maximum wattage rating for each voltage supplied no matter how they divide up the power.
It's not the number of rails, but the amps on your 12v rails. And multi-rail PSUs usually have half the amperage, leaving the potential for a power-hungry PSU to overload a rail even though the total potential wattage of the PSU is higher than is being consumed. But, sure, generally if you only buy well-reviewed PSUs and don't try to be cheap, you'll be fine. My favorite way to explain it: If your whole PC had to hang from a cliff by a rope in order to operate, would you even consider buying cheap rope? No? Then buy a PSU that's better than what you need and with a 5-year warranty. Save money somewhere else.
Go single rail. I had literally the exact problem that he described. 200 watts to spare and my PC was crashing during gaming sessions on my 4rail PSU any time I plugged in another expansion card. Got a different PSU with 1 rail. No problems yet.
I loved the funny way you explained single rail vs multi rail power supplies. I got a good laugh and you did a very good job of educating me on these power supplies. Thanks.
I'm already using Audible, it's great :) And I don't mind the sponsor ads, as long as it comes in the end of the video. I like Linus has a way of making it different every time even though it's the same sponsor :D Love this channel, keep making videos! Aaand if I can help you with anything just ask :) Great! See you in the next video :)
I don't need to watch this tutorial I already know everything possible about PSU's. Single Rail means only 1 train track is between the PSU and your CPU, Multi Rail means multiple trains can go and come from the CPU and PSU at once, this means more Lemmings can be brought from the PSU to the CPU and vice versa, making an amazing society right inside your PC. Told you, I'm fucking smart.
Multi Rail power supplies are able to give clean power faster to your PC making your PC improve in performance, and speed up your entire system making it go much faster without ever having to worry about overheating or crashing. -lol
So many dirty jokes can be made in like every techquickie episode lol. Makes sense since the channel has technolust names. Tech "quickie", A "FAP" ect.
WAIT WAIT WAIT WAIT!!! Linus Sebastian, what are you doing?! 0:25 - "12 V, 5 V and 3.3 V current". Really? I know you are better than this Linus. It's 12, 5 and 3.3 volt voltage, not current. Sure I understand what you mean, but so many people that are new to these terms (especially on this channel) watch your videos and will learn from you, so please be more correct than not correct :)
MrTheBmeister I'm not natively english speaking, but I'm quite sure the definition of voltage is potential difference. If not so - what's the difference?
I am aware this is a very old comment, however Linus was actually correct. The wires do indeed carry current, at 12, 5 and 3.3 volts. Power, or watts is =volts*current after all.
My XFX PRO Black Edition, 750W PSU melted the PCIE Graphics cable and the socked and cable fused, PC still worked until i loaded a game and than it crashed, so most PSU manufacturers now supply daisy chained gpu cable, and my OC GTX 980Ti may have over loaded it. XFX Warranty in UK is CRAP OR NON-EXISTENT.. on another note Audible is so addictive i keep buying books as well as my membership not good for my pocket but enjoyable
I have a power supply that has 4 12 volt rails at 20 amps each, based on my calculations my processor uses over 20 amps by itself, and it shares a rail with the motherboard connection.... is this why I am having issues overclocking??
AC / DC ! LOL ! I doubt not many notice the way Linus wrote the words AC and DC in that font for a reason. Im rocking on a Multi Rail PSU =) But just make sure that the Rails your using for your component has sufficient AMP to power it that's all it matter most. If not well like Linus said, sudden shut down during intense situation. But don't worry if for example your system uses 350W , you get like a 550W or more PSU , the rails will usually have enough AMP for your components. And Linus , you forgot Grounding , you only mentioned Volts =)
Well, there's some truth to this, but before the current days of PSU manufacturers inbreeding components to match spec... multi-rails were just unstable from mfg to mfg. I'm still using the single rails as I would if I were still working on military radars. The only difference is the cost in that it's cheaper to produce multi-rail PSUs vs. the single rail unit with higher spec'd components I.E. ICs, VRegs, C, & T. Rebranding is big nowadays...
my second power suply dos not have the 24pin(motherboard). Can I just huke up the green wier and a black wier to the corect position's on the add2psu adapter or does it need all the wires in the corect places ?
ok, question. installed r9 270x. started having system crashes. pulled case cover and discovered that only one of the 6 pin power connectors was fully seated into the GPU. the other one could not have been providing power to the GPU. I plugged it in better but did i hurt my new card in the process? ps. its a supposedly a single rail psu if that matters.
what happens if someone's psu have only 1 pci 6pin connector, and although not recommended he uses a molex to pci adaptor for his 2 connector graphics card... but turn out internally the pci is on 1 rail and the molex run off another rail. will this actually be a problem due to tecnically different currents meeting, or is this actually ideal?
iv a corsair ax 1200i but iv bought it second hand it says in the manual i can have singal or multi but as iv no dongal to change any ideas how to get round it with out having to buy a dongal
Watching videos like this one and reading reviews,I realize this: The most important is to have real power PSU with no stability issues at overload,and more amps is better at DC OUTPUT +12V ! I'm I right?
ok I been doing computers a long time and and electrician too and there is a huge difference in single vs multirail psu's firstly the reason for the cheap large output psu's is because 6 lower current switchmodes is a lot cheaper than 1 large one also when they refer to overload protection its on the mains side when you loose a rail that's just a small thermal cutoff by which time damage has already occurred but none of the safety mechanics built in protect your mb or cpu or gpu because they all need different amounts of power so it impossible so as far as high power usage pc's go single rail is really the only option
CX 600m it's a single rail (highest power draw my pc ever gets is 480w though (100+TR 100+VS 100+NC on the crown)) but this worries me, will the single rail be okay for extremely intensive gaming?
So I have a question... I recently bought a pair of 480's and an HX750w psu (yes, I know 480's are old, and no, I'm not replacing them). I believe the HX750w is a single rail with 62a on the 12v rail. I read somewhere that a single 480 needs at least 48a on the 12v rail... with 2 480's, would that mean I'm only getting 31a to each card? Isn't that... unsafe? Or does 62a on a single 12v rail mean both cards will get the 48 amps they need?
I have a Hiper Power 880w PSU with quad rails from 2008. I've just got a GTX 1080ti to add to my system along side a GTX 670 and the system is shutting down/restarting when I try to game. Possibly because of the rails OCP?
Jesse O Why would anyone above the age of 5 want to hear someone else read him a book instead of reading it himself? I just don't get it. Did you enjoy that at all?
expertdcv Well besides the obvious reasons, such as someone being partially or even fully blind, and someone having prosthetic hands, there is the fact that people are more happy and therefore more productive during work when they have a book being read to them, this practice is especially true in south american cigar factories. Audio books are also great for those that have very sensitive eyes and get headaches very easily because of it, and they are also just great for falling asleep to.
If that happens your house surge should take effect. Most good power supplies have plenum shielded cables. This takes the fire component out of the picture. The other argument is shock and death. This is false as 250ma can kill you with certain death around 750ma. If you go cheap go multi rale, Single rail is ok if you go expensive.
PSUs that are single rail on the box aren't single rail in reality. The power losses from Joule heating (i²*R) would be pretty untenable with some of these ratings. Just imagine your 80+ platinum Corsair PSU losing 81²*R watts every second it's plugged into something with resistance R. It makes far more sense to split it up into multiple rails and connect stuff in parallel to get the higher current as needed
That Austin joke was awful haha
so awful it was guuuud!
It was in poor taste tbf.
***** you must be fun at parties, tbf. I sure even Austin would laugh at this.
***** Even Austin himself poked fun at it. The dude is so crazy positive about the situation, it's really admirable. I'm sure as Maxime said, he'd even laugh at it!
I burst out laughing.
Silly LinusTechTips, rails are for trains! #lolz
LOL
hahah good one!!

**Facepalm**
@imgone uhhh, this was from 6 years ago #lolz
What you did to Austin was evil. I liked it.
What, sexy touching?
so real
Whats funny is that Austins "its all gone" video about his house is in my recomended for the video XD
+jpotts1515gaming Same here
You showed Austin because his house burned down. What I don't understand is he was laughing and smiling after he lost everything, why? I couldn't do that.
well, there is the "not being dead" part involved... I think?
I would be smiling too, after I receive the check from the insurance $$$ to get new stuff :D
Lars Reviews but i dont think Austin had house insurance or did he?
Moises Flores Not enough to cover all of my stuff.
Because he knows that things can be able to be replaced, and is just a matter of time.
Let me give people advice, when it comes to PSU's never by cheap ones, my cheap one exploded on me when I put in my new GPU and it almost killed my whole system, luckily my motherboard saved all my parts because of it's short protection, if your PSU is sketchy replace it with something trustworthy even if it's 3x more expensive for the same wattage but it's common sense really.
That Austin Evans throwback tho
"A rail is just a fancy name for a PCB trace..." - I've heard of a rail, but PCB trace sounds pretty fancy
looks like Austin needs to put some Ice on that burn! (I was trying to make a play on words, about Austins house burning down, and Linus making insults that burn)
no need for an edit ;) cut that explanation!
Linus did contribute to the Mac pro that Austin was gifted so i guess Austin wouldn't mind
***** Well tbh, I didn't think my whole comment made much sense to me, so I added the extra, just because I didn't feel right about it.
He didn't want one really though, he was forced to accept it when people arrived to his house. :D
I dislike the fact that you ruined that joke with that explanation lmao
Lol I feel so bad for laughing at this shots of Austin Evans
Don't worry. Austin was okay with it.
I actually clicked the video and watched his cats. For about 10 minutes straight.
So basically I’m gonna switch between multi-rail and single-Rail every other day! Thanks Linus!

Very useful video as usual, Linus. I've got a miner situation and needed to do some research on PSU's. This was a great resource. :)
Linus, take note, THIS is how you do AUTHENTIC sponsorships. Just saying, first time I didn't skip the ad tbh.
That was a clever way of explaining why one should use audible.
Can't get over 1:15-1:16. Good job Linus!
Kudos to whom editing this video, I love the 4 motorcycles part :)
Go single rail. I had literally the exact problem that he described.
200 watts to spare and my PC was crashing during gaming sessions on my 4rail PSU any time I plugged in another expansion card.
Got a different PSU with 1 rail. No problems yet.
Never heard of this rail thing in my life on PSU's. Thanks!

I was really waiting for this...
i see what you did with the ACDC thing in the beginning...
At the beginning of this video was an ad with LTT guy. This video was with LTT guy. At the end of the video was an ad with LTT guy.

Q: Linus, why would you even bring that up?
A: That's a good question.
End.

I like Linus has a way of making it different every time even though it's the same sponsor :D Love this channel, keep making videos! Aaand if I can help you with anything just ask :) Great! See you in the next video :)
It's in the middle of the video now 😕
I liked those motorcycle graphics. Good editing guys! I know I'm 6 years late but whatever.
4:00 - 4:15
terrific advertising.
I don't need to watch this tutorial I already know everything possible about PSU's.

Told you, I'm fucking smart.
Even Dr. Evil would go "oohh", when he sees the cute kittys.
I love as fast as possible. Great series!
So, then "single" means one, and "rail" means rail! And that concludes our intensive three-week course.
Just as I check the channel, a new video appears :D
I love the fact of youtube recommending me that Austins "It's all gone" video
I am going to build a PC with a 300w PSU, an Intel 4004, 12 kb of RAM and two Titan Zs. :) Perfectly balanced!
