FOOOOOLLL BRIGE RECTIFIAAA!! Is the right way to say it!! Thanks for sharing!
Hehe Buoy
Lol it's not a dumb single diode rectifier
HE SAID IT
I hate how he cut your video before the BOOM!
I feel like he shocked himself when he typed this
Oh my God... I can hear Mehdi from Electroboom saying "FULL BRIDGE RECTIFIER!!" in my head...
UNO reverse card
I was going to say the exact same thing xD
I really hoped they would make a scene like Mehdi's...
I'm disappointed that they didn't edit that in😔
Totally relatable 🤣
7:35 "In layman's terms, this 3,300 microfarad capacitor...."
Thanks. I just realised I'm not even qualified as a layman.
capacitor is similar to a battery. so when there is a need for more "power" it draws from it. microfarad is used to measure the capacity of a capacitor.
The capacitor saves energy in electric fields. Capacitance, measured in Farad, is just well... capacitance. I wonder why they use 3300μF instead of 3.3mF though
@@LKonstantina915 Bigger numbers sound better.
@@LKonstantina915 it's standard to refer to that size in uF. Not sure when the cut off is, but in my time I've not come across any mF caps. Only 25F supercaps and below that 10,000uF caps, or something similar.
Think of it like a water-tower - when there's enough power it charges up and then it discharges when there's too little power
as an EE student i can relate to this
In my country we learn this shit in highschool physics class i swear we learn too much man smh
⚰️⚰️⚰️
as an EE you should know as a student that what he's saying is technically incorrect, even though some parts are correct
but then again... let's understand that he's not an E.E. and lets understand that he's a Network Admin so yeah.. we'll cut him some slack
@@martinkuliza I am not sure we can cut some slack, when first 4 minutes are just wrong, Alex's part is mostly ok, and part about expensive power supplies is pure bullshit.
1kk of people now think: transformer + bridge rectifier = linear psu. Ffs, ltt, do some research.
EE gang rise up. I know your pain
As an electronics engineer I totally approve of this and want more of such turbo nerd edition! Great job LMG
same bhai
i am also studying electrical engineering
Check out Gamers Nexus as they go more turbo nerd.
@@hammadrazzaq6273 konsa kollege?
@@karehaqt agreeeeed. LMG is behind the curve
Ok
You could add “full bridge rectifier” voice by ElectroBoom. That would make it more epic and +3 to coolness
Yeah why not🤣
Yeah man was hopping for that sound. Electroboom will be disappointed in you
yes PLEASE 🙏🏿😭
Just not single punny diode
Yeah I was disappointed
"I would strongly recommend not licking these"
Too late... mm sparky
he shoulda said why we shouldnt lick these, now i really wanna try 🤤
you wont die but its not fun
**Ded**
Bulk capacitors would light you up. They're not kidding with that 250V on the side of them. And you have to double that because they're in series. Has to do with how the voltage doubling circuit works in a PC PSU. The switch on the side for 120-240 VAC input. When you switch it into 120 it doubles the voltage to bring it up to 240.
@@InservioLetum I can remember kids in grade school addicted to licking 9V batteries. I tried it, but it was not for me.
As an Electrical Engineer I have to say, Well done Linus, this is your most technically informative video yet. Would love more of these.
@Cpt America please don't major in it, you'd be an awful engineer
Why would he? Not interested in the field but how come he would be bad? @re4796
FOOL BREEDGE RECTIFIER!!!
the rectifiaeeeeee
shank, in the comments of a ltt video referencing electroboom, what a surprise
BEZAN LIKE-O!
Was waiting for an electro boom clip to pop in 😂
Edit: Oh wait didn’t watch far enough in
.... Rectum-fy.....
"A FULL BRIDGE RECTIFIER!!!!!"
-Mehdi
Edit: correction
YES
*Angry Mehdi noises*
Mehdi not Medhi
Exactly what I was going to comment! Lol!
Or An AvE Rectum fryer.
Mother of all full bridge rectifier
More turbo nerd - this series is awesome! Also, large props to Seasonic, this is an excellent piece of sponsored content, and it does actually make me even more likely to choose their products in the future once the GPU prices return to normal.
8:36 Lol 😆 They didn’t let Linus to finish
Linus: *mentions a full bridge rectifier*
Me: *deep breath* "FFFFUUUUUUU-"
FUUUUUUUUUUUU....
"-ULL BRIDGE RECTIFIEEER"
@@DirtyCasual36 “FOOOOOOOL BRIDGE RECTIFIAAAAAAH”
Ehh they aint that bad. Just a pain to troubleshoot if one goes bad and you dont see the rectifier lol
EVEN FUULLER BRIDGE RECTIFAYYAAA
When i hear "Full bridge rectifier" i hear automatic the epic voice from Mehdi
yes
As soon as the circuit was shown in the background, I hoped that Linus would do it.
This is exactly what I was thinking
As a sophomore in EE, and a frequent viewer of the channel, I very much enjoyed this content. I think you made the topic very interesting and appealing. Please do more!
Final year yet?
@@nishantsingh4929 63% done with my degree! Thank you for asking!
I don't really stop to comment on youtube videos that often, but I really want to sat that I love this "Turbo Nerd" series. That's kind of the perfect balance of entertainment and information to me. Good work LMG, and greetings from Italy!
As an EE designer, I appreciate the time you guys spent to get this accurate as possible while keeping the attention of those watching. Very well executed LTT team.
And they somehow get us engaged in checking out other Ytuber also, just massive appreciation
When they show mehdi sticking a wire in the socket , thats just the trailer
that video gave me an anxiety disorder, genuinely worse than any horror movie
they cut before fire probably
Thank you so much for this. Electrical engineering student. Struggled through a class on power supplies. Several lightbulb moments throughout this video!
I'm impressed you guys mentioned the secondary components like filters and PFC circuit. Good starts for anyone wanting to learn more. Also, that soft(or resonant) switching is incredibly important part of it all to let us have compact and efficient PSUs.
love the turbo nerd idea. would love to see more in depth content like this.
Couldn't agree more!
Yeah same! It's cool content
I was expecting a "FULL BRIDGE RECTIFIER" meme
I was expecting Electroboom to show up.
I mean, they did write it down on the white board the heay he says it :D
Hearing power factor correction took me back to my EE clg days. Used to have a tough time understanding why the hell they are not in sync. Understanding the full operation of power supply might need one to have master degree. Great job in explaining the basic concepts so easily.
I have a BSc in Electrical Engineering and 6 years of electronics design experience, and this video taught me about soft switching with an LC resonant circuit! Good job.
I can't hear or see "full-bridge rectifier" without my brain automatically translating it to Mehdi.
Saaaame...**F U L L B R I D G E R E C T I F I E R ! !**
@@nekomasteryoutube3232 *EVEN FULLER BRIDGE RECTIFICER!!!*
That remind me that insane fbr at 6× intensity
FRFR
Nor I. Knowing Mehdi has even BEEN on LTT (what with them both being in the Vancouver metro area), I'm shocked they didn't get a guest spot, or at least permission to use his voice for it. Cause that would have been awesome.
That "60 plus turd" power efficiency rating actually made me laugh 😂
I wish he said "60 + poop." I thought it was funny, but didn't quite laugh out loud, I think because turd in my mind refers more to the object than the material.
@📌 LinusTechTip don't scam people
But oh so wrong
LTTStore should sell that sticker.
Sounds like a GPM
Listening to Voltage, Amps, Watts reminds me of the physics classes from a long time ago, love this video concept!
same
Absolutely love the Turbo Nerd videos. Keep em coming!
8/10 needs more Brian the electrician
and Electroboom
Hm
I want to see more of this video for two reasons: more nerd tech talk and more importantly I want see more of that puppy.
Looks like we need SHORTAGES then and there to make these top channels make such videos..
It's awesome to see that amid the necessary sponsored videos and digital eye-candy we still see you guys turning out educational videos. Seriously, stuff like this is awesome.
Love this long-form, in depth, tech education format!
I wanna see more of this series,
3:00 Credit: Electroboom for all the knowledge 😂
This is a great kind of video to add to the stuff you post! This level of educational content is really awesome to have.
Great job. Really liking the simple explaination of how power supplies work. Quite a bit of research going into the script.
We need more of these Turbo Nerd editions
There's a very specific joy and excitement you get when you watch a video talk about something you went through university for and understanding everything that was talked and referenced about. As nerdy and boring the topic sounds, it was a super engaging video for me 🙂
Tyvm for add CC. Really appreciated.
This was a well-made and very informative video. Thank you for this. I also appreciate the shout-out to ElectroBoom as he teaches electricity.
I’m gonna have to watch this a few more times
Linus tries to blow up The motherboard.
Mehdi: hold my live wires.
Pro tip
*DONT HOLD THE LIVE WIRES*
@@carlweeks2399 unless you are ElectroBOOM hehe
This is an awesome video! I look forward to more content with this format.
This video was so much better than I expected and I thought it was going to be pretty solid to begin with
Great execution!
When I read the title and started the video I was preparing myself to close it after a minute because such a topic can be incredibly boring if not well presented.
Switching the host throughout the video, with clear topic separation, and without hectic cuts, gave the video a pleasant flow.
Probably takes a bit of courage to post "such" an educational video in the current YT environment so thanks for the well-executed, effort
and for fulfilling your guy's influencers' task to also educate.
(:
Felix retention Pond video Julio
Yes, switching hosts helps... Linus's part had horrible mistakes, Alex's was almost perfect, and last part was bullshit.
I love these kinds of videos from LTT - legitimately the most enjoyable type of content bc they explain it so well! Wish EE degrees were taught like this
the mobo changed from 0:19 to 0:29
Nice to see Seasonic get some attention. I recall telling one of my friends, who styles himself as a computer nerd, that I was going to get a Seasonic and he had never heard of them.
These Turbo Nerd things are my new favorite videos on this channel =)
I know this video was obviously planned and started weeks ago, but interesting that Gamers Nexus had a how power supplies work video less than 24 hours ago too
I like how GN showed us how power supplies work earlier today “Coincidence? I think NOT!!!”
I know... how strange!? Still have respect for both, but didnt sit right with me. For how much content LMG puts out daily\weekly; detailed PSU content coming days after GNs - just seems like a shot at GN not something they have been working on because they wanted to.
Taking advantage of the algorithm maybe?
LMG goes weeks between concept, writing, shooting, editing, and airing. Even live events are pre-planned and scripted. GN did a good intro to power supplies, with a focus on their intent to test power supplies with their equipment more so than the grade 9 introduction to electricity. LMG has also done a good piece on power supplies in line with a series of pieces they have done on parts of your computer at a good grade 9 introduction to electricity and grade 10 introduction to switch mode. There are easily two dozen other youtube videos on this same topic as well, search and you will find many from this grade 9/10 level to digikey employed engineer level.
@@informitas0117 They also talk to each other frequently and know what is coming from one another much before it does.
@@hellodoiknowyou5720 Yeah exactly, they may have had the script and video all done a while back but strategic posting to maximise viewership, no?
I want more informative videos like this. Do motherboards and ram next. Love it
More tubo nerd content please! This is a great series.

LMAO... my lab partner did in College just to prove it was no big deal. It did not go well. He then nearly killed himself changing the main resistive element in his stove... which he had not unplugged.
Some people learn from their mistakes. Some don't, and keep making the same mistake over and over. And some don't live to make the same mistake again.
These are actually amazing. Linus found a way to bring back his roots of the channel all while involving the rest of their team and their expertise. Love you guys long time
Wonderfully done

I have been using Seasonic for over 12 years, by far the best brand.
nah that's EVGA or Corsair
How do you know if you've only been using seasonic?
Lol at you arguing. Those are at par with each other, Seasonic, EVGA, Corsair.
SuperFlower (Leadtek) > them 3 though. ☺️
@@SUSHI4lyf Both corsair and superflower have made low quality power supplies.
Acolyte of Lucifer Where does Antec rate?
I love how both LTT and GN released power supply videos within 12 hours of each other without either one having any idea the other was working on one.
5:51 "I strongly recommend not liking these"
You sparked me wery old memories
He explained the rectifiers better in 2 mins than my physics professor in 5 lectures (1hr each), salute 🖖
Thats a sad indictment on the education system of today, but also cudos to LTT for doing such a damn good job...
@@375-Productions hey... they needed that extra grand ... plus more chinese grads...
This is grossly unfair to your professor. What he was explaining is probably everything about rectifiers, all the math pertaining to their operation, specifics that arise from the material used to build the thing and probably a lot more than I can think of right now.
Do you need all that to be able to make a circuit? No. But that's the difference between a technician and an engineer, and there is also the physicist of course. Chances are your professor could make a crude rectifier completely from scratch using only household objects. You might think you don't need that kind of information and you might be right but more knowledge is always better if you can hold all that in and will come in handy sometime. I experience that every day.
@@ahmetrefikeryilmaz4432 I think what they said was true with a lot of Education though, if your school, college or university teach you something and you still don't understand it, there are thousands of youtube tutorials to get you to understand it, and you usually will, much faster than school teaching you
Everyone just calm down it was a joke, stop taking everything so seriously, the world is a really sad place if you keep doing that lol
When i saw the title of this video I was like "O a new techquickie episode."
Yet this wasn't quickie or easy to understand

Linus Electrical Engineering Basics Tips. I love this.
When you watch Gamers Nexus' video released 24 hours earlier and feel like an expert on the content from this video.
Gamers Nexus was less educational and more amateurish in their presentation; they tried to educate and then review a psu in one video. Patrick's explanation of how the psu works was a quick whirlwind of technical jargon being thrown out without going into how they work. Steve and Patrick are learning as they go and try to put out a good review on a psu by supplying what data they can without checking the video over with experts in the PSU industry. Linus's video here focused on the educational aspect of how a psu works, and took advantage of the access they had to experts in addition to providing references for interested viewers. This is a much more organized approach, that is to separate how a psu works from reviewing one.
@@dont1973 I kind of admire Gamers Nexus' approach in trying something to see what works, what lands with viewers and shape how they approach this in the future. It's less polished than LTT but they don't have the same resources or staffing levels. It's very brave and they are obviously pushing themselves, which is great to see. I really think as an audience we are in a lucky position to be able to get such different styles of content and different approaches and I hope Steve and the gang get their footing as they have with other topics.
Linus looks like a great electrician.
