    This video was filmed at Corsair's lab just before our Newegg trip, featuring Jon Gerow of power supply R&D at Corsair (GN paid all travel expenses for itself). We talked about power supply tier lists, problems with standardizing modular cables, marketing BS about fans, full bridge rectifiers, 80 Plus Certification, and more. This is an educational piece that should help everyone learn more about power supplies for computers, including how to find the best PSUs in 2022 (and onward) and what specs are best for a power supply for a PC build.

      Really glad you had this interview, Steve. Moving forward, I hope GN picks up the PSU testing space for all of us, enthusiasts and PC gamers alike.
      We really need a no-BS JohnnyGuru-like PSU tests/reviews, and not just the usual 'repeat the marketing specs' PSU reviews in YT. 👍

      The first segment about not mixing modular cables is really good info for people.
      There's a reason why cablemod has specific modular sets for different brands/models.

    The fact that modular cable pinouts wasn't standardized 10+ years ago has to be one of the things in the PC world that grinds my gears the most. It's maddening, and dangerous!

    • The Tesseract
      The Tesseract Year ago +4

      I’ve blown up a few motherboards before because each had their own unique pin out instead of the atx standard

    • Bradley
      Bradley Year ago +13

      @The Tesseract I remember the old days of Dell and the physically compatible but electrically incompatible pinouts. Fortunately that's been the exception and not the norm. While proprietary power supplies haven't gone anywhere, at least they are clearly proprietary most of the time.

    • Insomniul
      Insomniul Year ago

      Even with standardized pinouts the modular cables are not really identical because they use different wires, different type of plastic for connectors, some have filtering capacitors, are of different lengths etc. Would it really be less dangerous to have an option to use "compatible" cheap cables on your 150+$ psu in a 2000+$ build?

    • Bradley
      Bradley Year ago +9

      @Insomniul Given that there IS a specification for the other end of the cable, that includes minimum current carrying capabilities, and 95% of use cases don't even come close to exceeding those, I'd say yes, it would still be preferable by a long shot. I don't buy cheap power supplies, so any of the cables available to me wouldn't be of questionable quality to begin with.
      Of course, most of my power supplies are already Corsair. And it IS nice that my 11 year old Corsair cables still work with my newest Corsair PSUs. But I also have a mix of EVGA and Cooler Master. And it's just flat out annoying how careful I have to be where-as every other PC cable I own is universal and I can just toss them in a box together.

      I don't think you'll see anything from LTT without brand bias. With how many business connections they have in the industry, I doubt they'd be willing to burn bridges over a shit product. Tech reviews in general should always be taken with a mountain of salt.

    • Plebis Maximus
      Plebis Maximus Year ago

      @BrainScramblies There is no difference, you're correct. Like I said, you shouldn't take tech reviews as gospel. Even the objective things like benchmarks should probably be taken with a grain of salt if they got the product for free, since it could be a special high quality media unit.

  • Mr House

    I always wondered why he stopped doing reviews. Now I know. Glad to see he's putting his knowledge into bettering the industry, or at least Corsair's part of it.

      Well in his time they have gone from making a range of what were essentially hot garbage from almost top to bottom, to what are now excellent units. It has taken some time (even as recent as 2018 they had some real duds out there) but it seems he has finally got rid of all their average quality stuff (that they sold for high quality prices) and now have waht is a solid range from the very lowest of their models. Just remember don't buy a Corsair PSU with a "v" in the name, thats old design bad stuff which unfortunately are still round in stock.

      @malphadour He has worked for Corsair for well over a decade.
      As to Corsair using him for marketing? That wouldn't sit well with me, but i can't quite put my finger on why.

    • malphadour
      malphadour Year ago +3

      @Siana Gearz Yes he has. But it didn't stop them continuing to sell old garbage designs for quite a while. The RM and CM series were the first that were completely under his overview, and they still managed to have problems with the pre 2019 RM models - thats why there are RM's, and RM2019 models - the 2019 being the revised ones which, btw, are very good now.

    You know, the ONE thing I will give Intel is that they had the ability to push things like the standardization of the power connectors between the PSU and Motherboard. Intel basically made the ATX spec and had the market power to get everyone on-board with using it. There are lots and lots of bad things they did, but promulgating the ATX specs was actually a good thing for consumers. Unfortunately in the PSU world, there is no one manufacturer or OEM with the clout to get everyone else to jump on the bandwagon of picking a standard for PSU-side modular cable connectors, and consumers are worse off for it.
    There doesn't seem to be a PSU standards group either, as everyone got used to letting Intel spend all the money to make the specs, and no one wants to spend the time and effort to work with their competitors so that consumers don't have to worry about accidentally using the wrong cables. Maybe the 80-plus guys could come up with a 'modular certified' sticker or something to indicate that a modular PSU conforms to a set standard for pinout and connector type? Unless Intel or AMD decide to come up with something, the 80-plus folks are about the only ones that almost all PSU makes work with, outside of government agencies.

    • VRNocturne
      VRNocturne Year ago +5

      I think this is one of the things that is hard to leave up to the market unless you do have an almost-monopoly like Intel. Otherwise, the market is designed to compete, not cooperate, while standardization requires cooperation and agreement to adhere to whatever it is.
      So I think someone will have to come in and enforce the standard just like we have for outlets in our walls. We don't have to match plugs to brands or have different draws based on what wires were used in the house. We don't have to worry if this "Corsair cord" will match my "EVGA wall outlet".
      Power supplies should be the same at that point. The difference is the innards and proprietary designs of non-user components.

    • malphadour
      malphadour Year ago +4

      100% second this, though Jon is still fairly active on some forums which is good for all of us. It shows the expertise required to properly review a PSU that there are maybe half a dozen respected reviewers out there (and I'm talking over the last 10 to 15 years) vs the fifty thousand people who review everything else.

  • Cheb Ornek

    Even if Jonny stopped doing reviews, he set a precedent for people being more aware of what to look for, and manufacturers being held accountable. I think GN is doing a similar job in case reviewing - even if you stopped reviewing cases tomorrow, people would still know not to trust manufacturer claims, what to look out for and what a useful review is.

      @malphadour and the reason why that hasn’t happened is stupid. Imagine if every phone brand made their own version of micro usbs 12 years ago - the smartphone boom would have been a nightmare

    • malphadour
      malphadour 7 months ago

      @Junya You are looking at the wrong object. The issue would be if every graphics card or motherboard had a different power connector. These are the same, so the power supplies are all following this standard - how it exits the actual PSU is less relevant unless you decide to swap cables. Yes it certainly would be nice if they were all the same, but in reality how often are psu cables swapped about?

  • Blazehoof
    Blazehoof Year ago +45

    I actually managed to fry a bank of 4 HDDs because of the interchangeable but not pin compatible modular cables...

    • Alejandro Suárez Mascareño
      Alejandro Suárez Mascareño Year ago +1

      @Blazehoof In my case I didn't even notice it was from a different power supply. I was making two systems with 2 modular PSUs from different brands and somehow I mixed one of the cables. They looked the same except for tiny text in one of them. Honestly, other brands cables just shouldn't fit.

    Would like to see a deeper dive, specifically on ripple and any factors that would determine overclocking stability. Yes protections are important, yes efficiency is important, but what factors makes a PSU good\bad for providing the most stable and consistent power delivery while pushing a system to its limits and why they are important.

I've been using the same EVGA Supernova 750W G2 in my system for 7 years now and I originally went with it after reading his very detailed review of it. The level of detail, thoroughness, and most importantly truly impartial and honest reviews are the same reasons I take so seriously all of your guy's reviews too.

      They would literally have to move overseas to properly test it. Just slapping a 220/240V plug onto a 110/120V extension cord and plugging into a 220/240V outlet isn't proper testing.

  • TheCloop123
    TheCloop123 Year ago +15

    I'm glad PSU tier lists was mentioned, I ironically had this debate with someone I know and kinda explained the same point Guru makes but as per usual many take those Tier lists as gospel forgetting its still going to miss "potential" faults that havent happened yet and when they do it then drops the Tier listing but it still gives a question of doubt to the user looking at them

    • malphadour
      malphadour Year ago +1

      I still largely ignore the tier list - there is so much bad info still on it.

    • QuantumConundrum
      QuantumConundrum Year ago +2

      The tier list makes sense to me as a heuristic until more precise data is available. I'd take a solid GN review over the tier list but what do you do when there's no equipment to do deep testing on failures? Short of becoming an electrical engineer myself, I have to offload the decision elsewhere. My point is that it's better than nothing, if only for just that psu with observed failures are likely to drop ranks the next year.

    • ProfChaos
      ProfChaos Year ago

      The problem is we can't find most of tierA and tierB psu review online, atm i'm looking for 3: Corsair Cx550, Asus Tuf bronze, Xigmatek minotaur. All of them in tierB, yet can't find a single review for them on the entire google

    • malphadour
      malphadour Year ago

      @ProfChaos I can help you with that. Xigmatec are terrible across the board. The Tuf bronze is ok- the 550 only has one GPU power cable, the 650w version has two - so for a mid tier graphics card )requiring 2 connectors)avoid the 550w. They are made by Great Wall who are a decent OEM and they also make the Corsair CX models(as well as CWT). Both brands are LLC with DC-DC on the secondary. This means it is modern design. The Asus Tuf usse Teapo caps which are ok, however the Corsair models use better quality ones - its a minor difference, but one that may make a difference as the units age. Of the two I would go with the Corsair model as their X ranges have proven to be solid units. With the CX models also check how many GPU power cables they have - the 650 has 2, but again i beleive the 550 is only one.

  • GypSy
    GypSy Year ago +1

    I miss Jon's, Gabriel's, Wolfe's and other psu Gods reviews, makes me wonder just how much of their critiques were taken to heart by designers and engineers and we get their improvements in today's better units. While I'm happy for them moving on or retiring, I'm also a little saddened that it seems Aris is the only one to be filling the huge void their departures left. We are desperate for real and honest info and dred the day we are left with marketing or half-baked testing to say what's what.

    • MartyNZ
      MartyNZ Year ago

      Glad you mentioned Gabriel Torres and Oklahoma Wolf too. I used to be obsessed with psu reviews over the years and since those guys moved on, basically only Aris has been covering reviews across a few sites. Still have many of my original HX620 Corsairs in use today not missing a beat. Used to love SilentPCreview's take on noise (audio) level too.

    Very excellent discussion. I was disappointed that during the half wave versus full wave Jonny didn't mention that half wave requires larger capacitors to try and achieve the same filtering. A full wave will typically have less ripple at it's output. More of this content would be great.

    man this was awesome, any chance you guys can ask him about sfx PSUs? i've always wondered if there was gonna be a point when those can actually replace the ATX format, which might give more space to cases to innovate
    EDIT: or even if there are any plans for new formats at all, or is there a specific reason for the standard "square"?

  • K Z
    K Z Year ago +1

    I remember going through the pain of choosing the PSU after old one went is smoke. Johnny's review helped me so much. I went with Corsair HX750i not knowing he is working for Corsair. Standardisation in PSU cabling/ pin layout would be great but I do not think it is a major concern. Could bring the prices down a little but not likely. People who are supplying aftermarket cables are capable of supplying correct cable based on PSU model. What would be amazing is to see better quality/ softer cables supplied as standard even if there were less of them included. I would prefer to be able to choose only cables I need and prevent e waste than having a ton of cables I do not like or need included and still being forced to order cable I actually want.

    What's funny is that everyone is focused on the Seasonic PSUs on the top shelf, but I'm also seeing a bunch of EVGA, Super Flower, there's a Super Flower on the cart behind Steve.... It's called competitor analysis people. I don't know why so many people are trying to read into this. We buy dozens of the competitors PSUs every month and throw them on that ATE. Everyone does it to everyone. Just this time it was captured on camera.

      Ask your wife/gf how her day went. When she's finished, you know pretty much where you stand, what you need to do in the next few hours, how you can improve etc. Everyone does that, but don't realize it. Pretty much the same concept as tearing into the competitions psus, seeing how yours match up, what you need to do next, what improvements you can make...
      It's not a hard concept to grasp and a great way to get the creative juices flowing.

    This was a fun video to watch. I think the biggest thing that needs to be discussed that is getting overlooked lately is capacity. With 4000 series graphics cards being rumored to pull a lot more power and 12th gen intel and beyond seemingly being very power hungry, it would help to have a source to help determine how much PSU you really need rather than the "power supply" calculators you see online.

  • Wa͟l̀ho͞r

    Every power supply I've purchased has been off the research done by JonnyGuru. I miss that website very much, and I hope that GN can eventually fill that role. Nobody else went into a fraction of the detail or meticulous testing, and their credibility was off the charts.

      @Lightly-red-hued male individual If you really think they're awesome, would you mind sharing? If they're that thorough, but small, then we should be trying to get their name out as much as possible, not gatekeeping who can see them.

    Another thing to consider is the fan they use to cool the power supply; if it goes bad you just have a loud or even overheating PSU.
    I got one of the 80+ Gold G2 Supernova's from EVGA and the fan bearing started making loud noises within a year.

    When I did my first custom loop build, I went with a purple and gold theme. The PC had been up and running for a couple weeks without issue. I decided I wanted colored cables and had planned on getting some from Cablemod but didn't have the money at the moment so I decided to get some colored extensions from Amazon. It came with enough extensions for everything that runs to the motherboard. I installed them. About a week later my motherboard failed due to a VRM short. I'll never use that stuff again. Cablemod, maybe, Amazon junk, nope.

    This is the kinda stuff I love Gamers Nexus for...I get to geek out and hear good old fashioned tech talk without hype and flash. It's just real down-and-dirty tech info. And yes, I was a kid that read "Upgrading and Repairing PCs" for fun. I used to know the pin voltages for 8-bit and 16-bit ISA slots. This stuff is what I love, and a hearing from a guru like him satisfies my need to know it's reliable and honest info. Kudos once again to Gamers Nexus for outstanding content.

    So true, great idea with modular but no standard at first. I ran into this about 5years ago after telling my son that it’s ok to plug in that vga cable into his brand new pwr supply. Heard a spark when we turned it on and it was over. So frustrated these top manufacturers aren’t professional enough to create a standard. Love Corsair and will stay brand loyal because it’s clear they are consumer friendly.
