Hello May i ask why the CX was not moved down to the category of overload ripple?

I got what you mean, but in relation to ripple it is shutting down when it should anyway. And it does not seem to be any hard to do? Many PSUs do that. In that old interview you already say a PSU should work well only up to its rated power, some e-mails Ronaldo receives from manufactiurers states the same. They say he is being unrealistic. Given the fact that all conditions are possible, i don`t think anything is unrealistic unless you presume the end users are experts. I initially posted the first video `cause the maintainers of this list think differently. They think like Ronald, it has to shut down before anything goes wrong. Intel processors are full of protections, unless you buy the K version at your own risk. Fortunately a CPU can only damage itself. But let`s suppose everyone agrees about up to its rated power, the CX temprature is bad at 550w and there is something else wrong with it. And why you review 110% yourself?

That is how a good PSU should behave overloaded, and this one is a cheap Corsair not in production anymore. It turns itself off with 26mv and just a bit higher than 40 degrees. cx430 5 years ago. This one has nothing to do with current CX. How is it unrealistic? It used to be realist for the CX itself. Edit: It seems to be at 220v so i am not sure

I am not familiar with the issues of the PSU models you mentioned, but EVGA is one he caught doing completely different batches to the same model,. CX is a great PSU except for ripple and temperature. Temperature gets bad enough at 100% load, so it is not good at all. You easily can find better cheaper, Super Flower King i already mentioned is one example and it is cheaper.

He does receive, i have no time to find it now. But i may do it later. At 230v it does not explode, for sure.

How it is not true, the temperature is insane and the 230v test makes no sense.The explosion test at 230v, all his tests are 115v, in Brazil itis 110v with the exception of a non relevant part of the country and it is already presumed to be better at 230v. He never tests a PSU twice unless the manufacturer/brand questions his tests which happens a lot, he even receives treats from PSU manufacturers. My conclusion is that he have read this topic and your comments and tested it again because you represent Corsair. In my opinion you have a wrong perspective, the people who tends to buy inexpensive PSUs are the ones not well informed or the well informed who is not wealthy and simply can`t pay any more.

I would not but you know that is not what happens in practice. You also know many PSUs turn itself off before putting the PSU or computer at risk, that is the whole point of protections. If people can only use it safely up to 550W the PSU should turn itself off at 550W,.

Firewrath9. It matters for your computer safety, you may have not dimensioned psu power well. Overclock may even double power comsumption, Also as you states a GPU particularly AMD may also have unspecified power draw spikes. It is not a problem to me either but i know what i am doing when building a computer, most customers and even vendors do not know. LukeSavenije totally agrees it matters, Seasonic Focus Plus v2 was downgraded in his Tier list exactly because at 120% load it would have high ripple according to a single Chinese web page. I even had a discussion with him about the Seasonic and got upset but whatever he believes that PSU has high ripple at 120% and won`t put it back in a high Tier. Ripple kills computer components, during spikes to more sensitive parts like your HDD or SSD ripple may burn those parts out of the blue and you will lose all your data. It is very sad. And do you think manufacturers care? They don`t, Corsair made a reputation 10 years ago or more when they were actually putting out quality in reasonably priced products like the CX but the CX had cost cuts to increase profits year and after year. Today something like the CX M is no different of a $10 generic psu. The 60mv of the CX at normal loads is completely fine but when you compare to 10-20-30mv offered by Super Flower and Seasonic in smilarly priced psus it gets bad! The CX high ripple shown in 5v and 3v rails at only 110% load may kill any hdd and ssd. Among well informed enthusiasts Corsair is known as the brand the offers less for more cash. The overpriced Corsair PSUs made by Seasonic, Flextronics are fine for the most part but CX, VS, CX M and probably the new CV are lemons with such issues and durability problems, but they have warranty! No, they do not. Their warranty is complete bullshit, they will have a burden of bureaucracy and if you pass over the bureaucracy they will try hard to find something to deny warranty, if you miss a cable warranty is denied. Someone close to me had his Corsair AXi warranty denied simply because Corsair would say it has no issues, it had a proven issue. In the end Corsair offered him a cheaper HX psu, he accepted because he was already tired trying to get his AXi replaced. And what if your computer was damaged over time due to a low quality psu? They won`t buy you a new computer as you may guess. The CX high temperature is also an issue, the psu won`t last and may even get on fire. When they tested if the CX would explode in the last video, they were kind enough to change voltage to 230v. At 115v it would explode. If you do not patrol companies they will have all sorts of questionable practices. Ronaldo from the videos i posted have found very interesting cases, like a psu from Xigmatek with 400mv ripple at normal loads but the interesting thing is that it had a fake component made of concrete to make the psu internals look better and heavier. He also caught companies doing different batches of the same psu model, some batches that get reviewed would be of good quality but other batches found in retail stores would be of lesser quality.

So the ripple supression and temperature are the issue, not the lack of protection..He is testing it again now. But people asked to test if it does explode. Edit: The PSU showed the same bad beahaviour, but if i got it right that ripple interference and high temperature went away after changing the voltage to 230 volts.

Teclab is live on Youtube right now, he said the CX550 result was atypical and that he studied it. The only conclusion he could reach is that it was an issue with the PSU ressonance, there is no operational mistake from his part.

Even if there is an error causing high ripple and temperature it shows the PSU has no working protections anyway

Before the second temp check while pointing to the wave abnormality the "slim guy" says "it is probably the primary suffering with heat". I would get surprised if he did anything wrong, also by my surprise he ended recommending the PSU in that same video but only up to 550W.

Nothing particular about him, it is just me. Regarding a possible error in the tests, i can`t have any word on it but luckly he will ge to know and give his version about it.

I don`t understand the gear used but even before they measured temps the slim guy actually setting it looked at the oscilloscope and realized the ripple was likely caused by temps because of the wave pattern, then he measured temps and it was super high. They tuned the psu off on purpose to give it another chance.

For those not familiar with the Corsair CX reviewer in the video. He was and still is an overlock competitor holding some world records for overclock. He did jonnyguru`s course, some of what he learned was with jonny himself. He used to work for Corsair many years ago. Currently he works for Galax which is a huge GPU manufacturer. No Corsair competitor, Galax does not make PSUs. He does all the Galax warranty service/repair in his country. He always says good things about Corsair and even jonnyguru. He used to release pre-recorded PSU tests, but after so many years of accusations of getting paid by Corsair and sometimes other brands he decided to do all PSU tests live. He does not even choose the PSU that will be tested, it is chosen by people on Facebook. He always buy the PSUs in a retail store and shows proof of that, also always shows PSU serial number, sealed PSU box and sealed PSU screw. He also examinates the PSU internals so that anyone can check if it is the same as some othe runit. The methodoly is exactly the same for all PSUs, if it was overloaded all others were too.
