Jeez, this is really interesting.... just a thought, if you could get Jonny and Patrick in front of a white-board (or maybe a black-board would even be better), for a few hours, and just feed them coffee after coffee, with some editing and "host" snippets that could easily generate an amazingly interesting deep-dive series, for which this series could effectively be just a preview. I'm sure /dozens/ of viewers would eagerly tune in to watch such a show!

[@gmt-yt]

I keep saying this but we're all afraid to poke around in PSUs as everyone says we could die, apparently in earnest. There just isn't a ton of easily digestible information out there. Watching Jonny simply rattle off the major glossary terms is actually a huge help. Next stop: Wikipedia, obv. -- armed with a this jargon-lexicon, we'll all surely be better equipped to start understanding what's going on in these (often literal) black boxes.

[@kidman2505]

I actually deal with EMI noise in my field of work. In Controlled Environment Agriculture (indoor gardening) lighting is obviously important. 1000 watt electronic ballasts were the mainstay in the industry for a long time. And as it got more popular and Amazon brands popped up, there was also a HUGE uptick in EMI issues. Usually Cable service would get terrible for anyone in the area, and it came down to cheap lighting ballasts just BROADCASTING massive interference. Usually this was discovered by someone else and they would call their Cable company and they'd send someone out who would at some point end up at the address, because the interference was so great, that their meters led them directly there. Crazy important part of an electronic device.

[@chunkychuck]

I commented on this elsewhere but do you know if this could be what causes dimmer switches to have problems? I've heard of it with some EVSEs ("car chargers")

[@arthurmoore9488]

Random Signals and Noise says Hi... More seriously, I don't think modern power supply design was covered at all in my EE courses.

[@Gabu_]

@@arthurmoore9488 Switching power supplies generally aren't covered much, unless it's specific for a graduate degree in Electrics/Electronics Engineering (at which point, you'll passively learn about most of the component circuits and get to combine them all at the end). Pretty difficult to teach someone how to regulate a fast switching MOSFET signal when they don't even understand what a MOSFET signal is.

[@richard-davies]

Always love watching Jonny Guru content, could watch hours of this content as it's really interesting on how PSUs are built and work 🙂

[@UniCrafter]

Fun fact also about power supplies I don't think was mentioned, the MOSFETs used for switching often have drain connected to the body, so in some cases the heatsink can be live, once blew up a PSU when a screw fell in right between two heatsinks. Also, regarding the MOSFET full bridge rectifier, really handy for high current/low voltage applications. I made my own for 12v/200A, diode based rectifiers commonly have a 0.6v drop across them, which is 120 watts of loss before resistance is considered, so I gained a solid 5-10% efficiency bonus going with an active solution.

I wish Corsair clearly advertised the differences between models like the rm850 & rm850x . Had I realized, I would 100% have gone with the rm850x for the maglev fan & higher quality caps over the rm850 I put in my latest build.

[@Kevin-ps1lf]

I would imagine you wouldn’t see the difference in reliability or performance. Maybe the fan would be noisier or more whine from the psu under load? I wouldn’t worry personally.

Lol, read my comment above. Search the internet for Corsair AX1200i PSU shutdowns, designed by Jonny freaking Guru, there are a TON of users reporting malfunction. I have 2 units and they've given me problems and more problems, and they were very expensive at the time. Wouldn't be surprised if other Corsair models were having similar problems, their current reading and protection malfunction is a complete disaster. Had so many problems that will never buy a Corsair PSU again, will go for Seasonic or EVGA instead.

[@HDJess]

I've head a cheapo Corsair PSU in a secondary PC (450w or something) and it was horrible. A lot of coil noise and random shutdowns for no reason on a reasonable configuration, i5-6500 + GTX 1650, 2x8GB, 1 SSD. There's no way those components topped that PSU. But for $30-40, no brand can make a decent PSU.

[@zablogful]

Here's a story about my Corsair Hx1200i, one morning I started my pc and heard a bang from the case and a burned smell came. The pc would not boot anymore and before that I've had a lot of problem with starting or stopping this pc, for example I would need to press the power switch a few time to start or the reset wouldn't work or it wouldn't shut down properly and I would need to use the switch at the back of the PSU. I've sent it for RMA and they sent me the same model but refurbished, same problem came back in 3 days, pc wouldn't boot anymore, something tripped the security. So I thought my motherboard was bad and I made a new build, same problem happened within 1 day so I bought a Seasonic 650 watt gold for my old build and Seasonic 1000 watt platinum for my new build, problem is fixed ever since. Corsair refused to refund/store credit my 400$ refurbished PSU they only wanted to RMA it for a second time which I refused since I needed to pay the shipping again for a piece of crap useless PSU that would or wouldn't work. Don't buy corsair PSU, get Seasonic or EVGA.

[@heni63]

You're really extreme in this comment. Maybe re read and also think about that this probably happens with any brand at some point. I could make a big picture of you and post why I think this is wrong of you, and you wouldn't like it because... It's often just a part of you. Pointing out mistakes by others helps, but completely judging over it by one negative situation is usually wrong

[@zablogful]

[@CoverMechanic]

yeah the bridge rectifier does not produce 420-470 volts DC, and the values written on the caps are absolute maximum ratings, usually nearly twice as much as they are actually handling. They will be 470v rated to handle the max input voltage of 240v, most likely.

This was such a cool video. I have no idea how it works but it's nice to hear a pro and how this will trickle to better GM in the future.

[@Toble_Miner]

Hey GN, thanks for the high quality content as always. There are a few inconsistencies in Jonny's explanation that I'd like to point out though: 5:14 - This is definetly not the 5VSB supply. As Stone later points out correctly this is the active PFC inductor. 13:10 - The placement of this part almost certainly disqualifies it as the LLC series inductor. The LLC series inductor should be very close to the primary of the main transformer. My best guess would be that the LLC series resonant inductor is the one to the top right of the main transformer and that the part pointed out here is the transformer for the 5VSB flyback supply. 22:20 - Yes, there is a small voltage drop in rectification. However the rectifier output voltage will still be higher than 120V, since 120V refers to the RMS mains voltage. However when rectifying the mains voltage and storing it in a capacitor it will charge up to the peak mains voltage which is sqrt(2) * 120V. Another few comments from my side: 15:00 - Actively clamped topologies are usually not more efficient because the waveform is more compressed. Rather the spikes are effectively fed back into the main bus capacitors instead of being dissipated in passive clamping solutions like snubbers. Importantly it can also extend the usable power limit of the forward converter since demagnetization of the transformer core happens more quickly. 23:10 - Another interesting and important design aspect of bus capacitance can be impedance. Using a single, large capacitor versus multiple smaller capacitors in parallel will have a significant impact on the effective bus impedance over frequency. Depending on the exact design of the power supply this can make a huge difference, especially with respect to (conducted) EMI emissions.

[@maygol]

Now I'm even more pleased on having a Corsair PSU! thanks Steve!

[@kooshini]

Thanks, the information I got at 11:10 about the hard switching just solved my issue. I have a 3090ti and my new 1000w Gigabyte PSU was making a really annoying noise.

As an electrical engineer I was able to follow along but to make this more approachable to lay people briefly explaining what the components that your listing would be helpful. Perhaps diagrams?

Very fascinating video! awesome 😀

This is super interesting to know. Really cool variety of content guys, usually I'm more attentive to GPU and Processors, but now that I'm looking to buy a new motherboard and PSU, really glad I can resort to you guys to check what should I buy.

Love a good optocoupler! Hoping you guys are going to build out some reviews and charts to help us consumers better understand what we're getting for the money, especially when comparing higher end gear with a premium. I'm sure we've all wondered at some time or another if the most expensive truly is the best.
