    All the time I'll see people recommend PSUs based on efficiency. This, although fundamentally a good idea so that you don't end up with a stick and some chewing gum powering your system, shows that most do not understand what 80 PLUS efficiency implies. Let's get a couple myths out of the way:

    - "A higher 80 PLUS rating correlates to better quality." Incorrect. Certain components in a PSU do need to be of a certain quality to achieve higher efficiency (typically MOSFETs and diodes), however, quality of soldering, certain capacitors, etc, can be forgone in achieving an exemplary 80 PLUS rating. Electrical performance can be ditched as well. I like to use the EVGA G1 as an example of this. It's made of above average componentry, performs lackingly, and achieves gold efficiency. Then there's the EVGA B2, which is constructed about as well, performs better electrically, and advertises 80 PLUS Bronze efficiency (it actually achieves 80 PLUS Silver efficiency but that standard has been given up by and large). The EVGA B2 is a better PSU than the G1, yet it wastes slightly more electricity. This will correlate to a marginally more expensive power bill (pennies on the dollar for most home users) but ensures you a better power supply for your money. If, however, you plan to run a very power-hungry system for several hours on end then a more efficient power supply can save a more noticeable amount of money, especially if used heavily during hours of the day where electricity is more expensive.
     
    On another note: some brands will undersell their unit's rated wattage if it can achieve higher efficiency at lower loads, I.E. a brand may sell a 550W 80 PLUS Platinum rated unit that can actually output 600W+ but would have to be advertised at a lower efficiency rating if they were to sell it at that rated wattage.

    - "Higher 80 PLUS efficiency keeps the PSU cooler." Not to any serious degree, but this is technically true. A less efficient PSU will waste more electricity and wasted electricity is turned into heat. This is not likely to have an appreciable impact on the temperature of your room or system however as your system doesn't really draw that much power, thus it's better to optimize your system's airflow before throwing an AX1500i in your system to minimize heat created by the power supply. Since PSUs exhaust heat anyways the temperature of your system's hardware will not be impacted to any noticeable degree. Different PSUs also handle cooling differently and 80 PLUS efficiency doesn't correlate to the size of the fan used or the heat-dissipation abilities of the unit.
     
    - "Power supplies are most efficient at around 50% load." This is, by and large, untrue, and seems to be set in stone by many simply because the peak efficiency measured by Ecova's testing of just three load levels is at 50% always. Many manufacturers or reviewers test PSU efficiency at different loads and post charts online, if this matters to you, but many PSUs are more efficient at 60% load than 50% and many are more efficient towards 30%. Don't buy a PSU based on how efficient it will be with whatever hardware you have in it. Different topologies and different PSU platforms handle efficiency differently. This should be a non-issue and you should be looking at buying the best PSU you can get with your money.
     
    - "If you have a 1000W PSU with an 80% efficiency then you are only going to be able to get 800W from your power supply." This is incorrect. If you have an 80% efficient 1000W PSU then, when putting it under enough load to max its output you are going to be drawing more power from the walls - not losing output from your power supply. In this instance, putting a 1000W PSU under max load with an 80% efficiency would mean you're drawing 1250 watts from the wall. Math goes as such:
                                                                                                    X / Y= Z                  
                                                                                            1000W / .80 = 1250
                                                                                      1250W drawn from the wall

    X represents the wattage you're using (say 350W with a Ryzen 7 3700X and RTX 2080 Super under 100% system load), Y represents the efficiency in decimals (an 85% efficient PSU would be .85), and Z represents your total system draw from the wall. For this calculation we're assuming that the PSU in question has exactly enough wattage to power the system at 100% load and is 87% efficient at 100% draw, making it an 80+ Gold efficient power supply.


    So in our case with the 3700X and 2080 Super:
                                                                                                   350 / .87
                                                                          = 402 watts drawn from your power outlet
     
    Note, however, that efficiency is not consistent throughout the load of the power supply.

    Power supplies are more and less efficient at different loads. They are also more efficient when connected to a more powerful grid, the 230V nominal, which you may use if you don't live in North America. Check that your PSU allows for operation under both voltages. Most modern ones switch operation automatically. Other, often older units, will have a hard switch at the back of the unit to switch to choose from either 115V or 230V (note, DO NOT SWITCH TO THE ONE THAT DOESN'T MATCH THE ELECTRICAL OUTPUT OF YOUR WALL OUTLET! This doesn't usually end well!). This graph demonstrates the efficiency curve of a 2011-era Corsair TX750 when plugged into a 115V AC versus being plugged into a 230V AC. Note the TX750 is an 80+ Bronze rated PSU.
                    
                                          
     

    If you live in the United States, for example, you are using a 110-120V (115 nominal) AC through a standard NEMA 5-15 socket. Your power supply may be more or less efficient than your manufacturer claims because they may advertise efficiency through a 230V AC, though standard 80 PLUS efficiency testing is done on a 115V AC. Note that these tests for efficiency are also done under very specific test environments and do not necessarily reflect real-world scenarios so you may achieve higher or lower efficiency than rated by the manufacturer.

    And just to finish up let's go list the various 80 PLUS ratings and their efficiency at different power draws on a 115V and 230V AC as well as 230V AC redundant.
                                                                                   
     
                                                                              
    Note that Silver isn't really used anymore and the efficiency of a PSU that would achieve Silver certification would typically just be rounded up or down to Bronze or Gold. "230V internal redundant" refers to efficiency in a redundant scenario like in a data center. This guy from Dell explains it.
     
    One last thing I want to make a little more hard-hitting here. 80 PLUS efficiency ratings were invented to save corporations and industrial services money in the long-term, not home users! A company with 1000 computers all consuming 100W for 10 hours a day will see a much greater benefit from having all 80 PLUS Titanium units in their systems than you likely would with your system. Don't spend tons of money trying to get a super efficient PSU when a PSU that's just as good, costs less, and achieves a tier lower 80 PLUS rating is drastically cheaper.

    There won't be a big WAN Show segment about this or anything. Most of what I have to say, I've already said, and I've done so privately.

    To Steve, I expressed my disappointment that he didn't go through proper journalistic practices in creating this piece. He has my email and number (along with numerous other members of our team) and could have asked me for context that may have proven to be valuable (like the fact that we didn't 'sell' the monoblock, but rather auctioned it for charity due to a miscommunication... AND the fact that while we haven't sent payment yet, we have already agreed to compensate Billet Labs for the cost of their prototype). There are other issues, but I've told him that I won't be drawn into a public sniping match over this and that I'll be continuing to move forward in good faith as part of 'Team Media'. When/if he's ready to do so again I'll be ready.

    To my team (and my CEO's team, but realistically I was at the helm for all of these errors, so I need to own it), I stressed the importance of diligence in our work because there are so many eyes on us. We are going through some growing pains - we've been very public about them in the interest of transparency - and it's clear we have some work to do on internal processes and communication. We have already been doing a lot of work internally to clean up our processes, but these things take time. Rome wasn't built in a day, but that's no excuse for sloppiness.

    Now, for my community, all I can say is the same things I always say. We know that we're not perfect. We wear our imperfection on our sleeves in the interest of ensuring that we stay accountable to you. But it's sad and unfortunate when this transparency gets warped into a bad thing. The Labs team is hard at work hard creating processes and tools to generate data that will benefit all consumers - a work in progress that is very much not done and that we've communicated needs to be treated as such. Do we have notes under some videos? Yes. Is it because we are striving for transparency/improvement? Yeah... What we're doing hasn't been in many years, if ever.. and we would make a much larger correction if the circumstances merited it. Listing the wrong amount of cache on a table for a CPU review is sloppy, but given that our conclusions are drawn based on our testing, not the spec sheet, it doesn't materially change the recommendation. That doesn't mean these things don't matter. We've set KPIs for our writing/labs team around accuracy, and we are continually installing new checks and balances to ensure that things continue to get better. If you haven't seen the improvement, frankly I wonder if you're really looking for it... The thoroughness that we managed on our last handful of GPU videos is getting really incredible given the limited time we have for these embargoes. I'm REALLY excited about what the future will hold.
     
    With all of that said, I still disagree that the Billet Labs video (not the situation with the return, which I've already addressed above) is an 'accuracy' issue. It's more like I just read the room wrong. We COULD have re-tested it with perfect accuracy, but to do so PROPERLY - accounting for which cases it could be installed in (none) and which radiators it would be plumbed with (again... mystery) would have been impossible... and also didn't affect the conclusion of the video... OR SO I THOUGHT...
     
    I wanted to evaluate it as a product, and as a product, IF it could manage to compete with the temperatures of the highest end blocks on the planet, it still wouldn't make sense to buy... so from my point of view, re-testing it and finding out that yes, it did in fact run cooler made no difference to the conclusion, so it didn't really make a difference.
     
    Adam and I were talking about this today. He advocated for re-testing it regardless of how non-viable it was as a product at the time and I think he expressed really well today why it mattered. It was like making a video about a supercar. It doesn't mater if no one watching will buy it. They just wanna see it rip.  I missed that, but it wasn't because I didn't care about the consumer.. it was because I was so focused on how this product impacted a potential buyer. Either way, clearly my bad, but my intention was never to harm Billet Labs. I specifically called out their incredible machining skills because I wanted to see them create something with a viable market for it and was hoping others would appreciate the fineness of the craftsmanship even if the product was impractical. I still hope they move forward building something else because they obviously have talent and I've watched countless niche water cooling vendors come and go. It's an astonishingly unforgiving market.
     
    Either way, I'm sorry I got the community's priorities mixed-up on this one, and that we didn't show the Billet in the best light. Our intention wasn't to hurt anyone. We wanted no one to buy it (because it's an egregious waste of money no matter what temps it runs at) and we wanted Billet to make something marketable (so they can, y'know, eat).
     
    With all of this in mind, it saddens me how quickly the pitchforks were raised over this. It also comes across a touch hypocritical when some basic due diligence could have helped clarify much of it. I have a LONG history of meeting issues head on and I've never been afraid to answer questions, which lands me in hot water regularly, but helps keep me in tune with my peers and with the community. The only reason I can think of not to ask me is because my honest response might be inconvenient. 
     
    We can test that... with this post. Will the "It was a mistake (a bad one, but a mistake) and they're taking care of it" reality manage to have the same reach? Let's see if anyone actually wants to know what happened. I hope so, but it's been disheartening seeing how many people were willing to jump on us here. Believe it or not, I'm a real person and so is the rest of my team. We are trying our best, and if what we were doing was easy, everyone would do it. Today sucks.
     
    Thanks for reading this.

    First of all, the whole Billet Labs stuff is completely absurd if true. I don't think they would intentionally sell something they couldn't, probably some massive fuck up in communications happened between the team responsible for sending it back and the people choosing the items to be auctioned, but it's still a huge issue and 100% LTT's responsibility to fix it and make sure something like this never ever happens again. 
     
    About the rushed content, it's something that a lot of times crosses the border of "fun jank" to being just frustrating. Every single project they do seems to be rushed, unfinished, untested and plagued with issues and oversights. And that could be their content "brand", seems like many people enjoy the jank. But if they now want to present themselves as serious testers, someone the community can look up for reliable data with Labs, that mindset needs to change, FAST. How the hell can I trust someone who has to correct themselves almost every video? And makes errors that a basic review of the content could catch? 
     
    You need to pump out 7 videos a week? Sure buddy, but maybe allow more time sensitive projects to be properly planned, executed and reviewed and throw some "here's 10 fun crap we found on aliexpress" videos to make up for it.

    That waterblock review from LTT is truly messed up and misleading and Linus should be ashamed of himself.
     
    1) refused to return prototype at request of maker, maker incurs financial losses making the prototype they will not see again
     
    2) sold prototype that could be reversed engineered and further damage the company if someone else manufactures it
     
    3) knowingly torpedoed the start-up's name and reputation with the video about a 3090 Ti waterblock not working on a 4090 video card, which can hinder future sales. but also open up the avenue for the buyer of the prototype to resell a reverse engineered version under a new name while the billet name is sullied by the review.

Then I bought a Ryzen 5 5600 and an RX 6700 (non-XT) and decided that there's no point in overclocking anything anymore when you can significantly undervolt it without any performance penalty. I don't know if that says modern silicon is just that good, or if it says that manufacturers just don't bother to optimize anything anymore.

    Then run it with a power limit. At idle the 12900K isn't that bad with power consumption, and under load it a power limit could keep it at whatever power draw you wanted (65W, 125W, etc.). You can always remove that power limit in the future if you do need more horsepower, but for the time being it'll keep your power consumption down.
     
    Just go 12900K, I don't see a single reason to stick with a 9900K other than it's a little more convenient not to swap the board.
