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)
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.
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.
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 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 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.
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.
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.
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 =)
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.
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.
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??
What happens to PSU companies in a few years when even the highest end PSU's dont need supplemental power? I mean sure build quality and efficiency would still be a thing i guess but are prices going to come down as well? Who is going to buy a 400w PSU for over 100 bucks or whatever 1000w units are going for today? If the 750ti is any indicator, in 3-5 years the top end GPU will probably consume 100w max.
So the greater question here is, when is it ok to use one cable from the PSU to power the GPU and when are two cables needed to adequately power a GPU? You mentioned this in a recent video and I cannot find clear answers. One person says two cables only if you don't have a cable with dual connectors (eg. 2 six pins) or if your PSU has separate rails. But in your recent video you mentioned using two cables regardless of dual connectors and here you say single rail vs multi rail doesn't matter.
That Austin joke was just rude. But he is back on his feet and hopefully the fireproof Nas you gave him is in use. But I doubt that will happen to him again.
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?
Funny...I only recently bought a PSU that is single rail. At the time, I was like, "WTF is a single rail power supply and why should I care?!" ...Now I know.
LinusTechTips in one of the videos were you show off your Windows home server, you say that you use a XXXXw multi rail for the many hdd's in your case. And now you say that it doesn't matter if you have a multi or single rail. Why? (comment ridden on my phone so can't be bothered to find the video)
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 ?
Each of my main PSUs have a single +12V rail rated for 83A. That just makes me feel all fuzzy inside. Speaking of fuzzy, clicking on the cat does nothing.
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?
This video (to me) seems to be inspired from the many misinformed comments that came about when you guys released that video: *Corsair AX1500i - The Best Enthusiast Power Supply. Period.* One of the threads I read had this one guy arguing, "single rail PSU are dangerous and are likely to start fire." and wouldn't concede regardless the many times he'd been corrected of the fact...
Now I feel even more worried about my PSU.. Already re-soldered a new fan to my TX650 board, now the capicitors sound like they are slowly going to pop... And I have random PSU outages. And my electricity trips out everyday. rip
Sounds like you need to get a good surge protector with a line conditioner/voltage regulator in it. Maybe even an auxiliary power unit. Bad electrical wiring in a house can kill a pc faster then anything.
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
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!!
xD
**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.
"A rail is just a fancy name for a PCB trace..." - I've heard of a rail, but PCB trace sounds pretty fancy
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
Lol I feel so bad for laughing at this shots of Austin Evans
Don't worry. Austin was okay with it.
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
So basically I’m gonna switch between multi-rail and single-Rail every other day! Thanks Linus!
"Yeah that's tasteless, deal with it!" lol, Best line ever!
Linus, take note, THIS is how you do AUTHENTIC sponsorships. Just saying, first time I didn't skip the ad tbh.
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.
I actually clicked the video and watched his cats. For about 10 minutes straight.
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.
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. :)
That was a clever way of explaining why one should use audible.
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.

Never heard of this rail thing in my life on PSU's. Thanks!
i see what you did with the ACDC thing in the beginning...
Q: Linus, why would you even bring that up?
A: That's a good question.
End.

So, then "single" means one, and "rail" means rail! And that concludes our intensive three-week course.
Even Dr. Evil would go "oohh", when he sees the cute kittys.
Oh Linus that was so wrong 02:14 lol
Omg I can't breath, the Austin joke was so bad but halarious!
Good ol' Linus. Still useful info today though.
I liked those motorcycle graphics. Good editing guys! I know I'm 6 years late but whatever.
Shots fired at Austin! Hope he is cool with that :)
But if there are too many rails the output power is split. Therefore a single rail might not be able to supply, for example, the gpu. Right?
Can't get over 1:15-1:16. Good job Linus!
I love the fact of youtube recommending me that Austins "It's all gone" video
Best, tech video, EVER
AC / DC ! LOL ! I doubt not many notice the way Linus wrote the words AC and DC in that font for a reason.

Kind of sad that Linus didn't do a pun or weird thing with the AC/DC band or something... but still informative video Linus!

I'm going to hell for laughing at the Austin burning house joke
Had to stop at the 3.3V current just for this comment. Nice mistake! :P

“So I can clearly not choose the power supply in front of you…”
I am going to build a PC with a 300w PSU, an Intel 4004, 12 kb of RAM and two Titan Zs. :) Perfectly balanced!
It's funny because Austin's house burnt down
+Wolfenberg oh yeah, you're right

The AUstin jokes where burn after burn. SO good
IDK if Linus saw my request to explain PSU rails, but if he did then that's awesome! But that Austin joke.....
Fastest tech quicky ever at 7 seconds long
What does this mean for PSUs that are both single and multi rail, like the be quiet dark power pro 10 with it's single and multi rail switch.
So that's why my freaking computer crashed every time I did intense gaming. TY LINUS.
Linus is the man, quick, simple, all the facts and funny to boot :-)
so, is be quiet sp u9 500w good for i3 9100f and gtx 1660 super ?
Can you make a video on what fan you should use were?
Also, I like how the "it's all gone" video is in related videos
Just a heads up. The video says single rail vs multi rail GPU. Looks like someone made an error in editing :)
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 read that the Asus Crosshair Formula V 990FX requires a dual rail power supply. Is this true or just a false comment?

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
