@@GtsAntoni1 Simple, just make the certificate valid for a certain number of units sold. So eg. for every 1000 PSUs you make you have to recertify. Add serial numbers to the certificate to prevent abuse and done. So lets say I am EVGA and I make PSUs. I first submit a unit for testing to get the certificate. Then as I am selling the PSU and I see I am running out of serial numbers, I call 80+ and ask for a new batch. They ask me for payment, grab a random PSU from the shelf and retest, if still valid I get another batch of serial numbers to use.

To be fair, 80PLUS was never _meant_ to tell you anything past general efficiency, so you can’t really ding them for issues around reliability, quality, etc. - we either need a set of other certifications for other points, or an overall certification that covers everything

Not sure, I have a EVGA one and even at 550W they seem ok, been 3 years now, no fires.

I have a Corsair HX620w. It used to feed a e6750 cpu and a 8800gt back in the day, then a q9550 and a gtx 680, now it feeds a i3 9100f and a rtx 3060. So it's a 16 years old psu still working silently, without any problem.

You say the extra wattage is lost as waste heat or goes back to the grid. This is incorrect. You cannot ever loose wattage 'back to the grid'. It always has to be turned into some kind of work (typically heat if it is being wasted).

As does 80 PLUS 115V North America, 230V EU, European spec for desktops as well as 2 Data Center PSU standards. All ENERGY STAR(R) and EU ErP endorsed.

I'm so glad that Cybenetics is including a noise rating in its rating system. I bought a power supply from Corsair a few years ago and that fan noise was annoying as hell in a quiet room. I mean, I've been playing PC games for several years, so I appreciated the importance of a quiet system. I knew to get a good CPU cooler and to read graphics cards' reviews to know which cards produced a reasonable noise level, but never in a million years did I expect I would have a noise problem from A POWER SUPPLY.

I've also seen that some test sites having a mixed recommendation, and sometimes, results between 110v or 220v. In 220v they pass but at 110v some of them fail. I think the Gammax PSUs had that.

I have a 600W LC Power PSU (12V Just 500W) and it still works over 10 years now. Its silent, cold and never failed despite tests have shown that it is bad. I guess I was lucky.

@OpenYourMind actually it's the other way around. Drawing 450W on 450W psu is a lot more stressful for hardware than drawing same 450W on 550W psu. In this case, since the total watts drawn are decided solely by your pc configuration, bigger psu is always better.

Cybenetics also has a certification system that goes beyond just efficiency and they even have a database where you can actually look up the components and construction of the PSU thats certified. It's high time we give others the recognition they need in order for companies to want to be certified by them and start using their standard. In Brazil some of the national "makers" are already doing this.

Just a note on the Cybnetics noise testing, it's done at 30-32° celsius ambient, meaning you should still look up seperate reviews for more modest noise data if you use your PC in a cooler environment.

been using Seasonic for nearly a decade and never let me down even pulling 700w from a 550w back when i was mining. never had an issue with any of them i have ever gotten and still have the first one i ever bought in it's box ready to be used if i need it.

I actually needed this video, thanks

Cybenetics thankfully also tests for Noise Suppression, a very important aspect of a PSU.

I saw reports on LTT forum that major manufacturers like cooler master sell inferior quality PSUs in countries like India where there are no reviewers. What they say is not what they give. Sucks to be those guys

Very well explained. Best explanation I have seen so far. Thank you.

Wouldn't it have been better to name the ratings 80+, 85+, 90+, 95+ instead of 80+ Bronze, 80+ Silver, etc?

The only thing I could the find difference was sites saying one used components from China & the other Japan. However I couldn't any verifiable information in this claim, just repeated the same info on different sites. Anyway, I went with the "better" one, RM850x, cause it was only 5$ more.

@Seth22087

Жыл бұрын

Not 100%, but Corsairs RM PSUs ending with X are basically newer refresh of non-X, so similar with some improvements. I think changes were as you mentioned Japanese caps, which are in theory more tested for higher quality, but in practice, this is more of something that used to be true, but now isn't even nearly as much. Plus quieter fan with MagLev barrings. And they put caps into cables too. Both latter stuff are more nice to have. If memory serves, RM series wasn't bad to begin with, so difference wasn't as impactful. I think CX series had bit more of quality improvement with CXM refresh, where you did want to get refresh.

Every modern browser follows the same W3C standards, with very little differences beyond bugs between them. So the vast majority of things targeting Chromium _should_ Just Work (TM) in Firefox etc. Bleeding edge features may differ in support/completeness between them all, however. As for why many target Chromium specifically.. the only popular modern browsers that aren't basically a rebranded Chromium (usually with other things added/tweaked, but the core is still Chromium) are Firefox and Safari. Chrome, Edge, and Opera are all Chromium under the hood and alternative browsers such as Vivaldi and Maxthon are also based on Chromium. Brave is an outlier in that it's based on Firefox instead. With such a large share of the browser market being taken up by Chromium (~85% going by a quick Google search, when counting Chromium-based ones like Opera and Edge as well), it makes more sense to focus efforts there over Firefox (~8%). This, unfortunately, means Google (who are effectively in charge of Chromium) effectively decides how the web works. W3C standards only become a full standard when "the majority of browsers" implement it, so if Google doesn't add it to Chromium, it doesn't become a full standard. (Someone correct me on this if I've misunderstood the W3C process)

lovely. improved certification. but psu choices quite limited here. :(

i didnt really took the color of the 80+ as a quality mark since i have first have experience on using 2 psu that is all 80+ white for 11 years (it was a seasonic 750w 80+ white) had both on a 1st gen i7 and i5 build that was OC permanently to 4.2 ghz (yeah im one of those guys who dont upgrade until it naturally breaks down on its own)

I have the dumbest quest of all, most of the stuff in the home is DC power, why not have a setup at yhe fuse panel. And run everything natively DC power throughout the home? Pretty sure that would definitely help with the who eco-friendly concept everyone talks about.

My friend has a neat way to workaround his kVa limitation of his Flat (apartment) Long story short, his Flat can only handle 240 Volt 2 Amp. Which means it can only draw 480 Watt of appliances at once. Anything beyond 480 Watt will automatically trip the Circuit Breaker. And then of course he has Rice Cooker, PC, etc etc that draws more than 480 Watt combined. So, how he outsmart this 480 watt Limitations? First off he bought a "Slow-start Transformer Step Up" and then manually wiring a custom Grounding route. And then creating a custom Cooling loop for the Transformer. By limiting the Power draw from the outlet at 450 Watt Peak, the thing will take roughly 1 hour before it can handle PC & Rice Cooker at the same time 24/7 nonstop. The 450 kVa from the outlet is increased to 4200 kVa. Now he has no problems using PC with RTX 3080, Rice Cooker, Air Conditioner, etc etc.

I never think that 80+ is /the/ selling point. I don't think I'd buy a new PSU without the certification, but I'm definitely more intrigued by higher spec 80+ ratings. I end up waaaay overbuying in PSU capacity (My 5800x and RX 5700 are running on a 1200w Be Quiet!
