Any chinese device with Nippon Chemi-Con, Nichicon, or Rubicon sleeved capacitors in it is automatically suspicious. Automatically think it was assembled in some slave labor camp or something.
@@erikas6874 If their ESR (equivalent series resistance) is low, they shouldn’t get hot. Cheap electrolytic capacitors however tend to lose/leak the electrolyte over time causing the ESR to increase which will warm them up which will accelerate the process. Sometimes leading to a catastrophic failure but most of the time just a silent death.
Interestingly, I bought that EXACT SAME SMPS last week and it has what appears to be the EXACT same layout and components, but it's 60v, 10A 600watts. It would be very interesting to send you some pictures and see how they get the different voltages and amps out of the exact same layout.
Damn, I wish you had powered it on before taking off the capacitors. Might have given some nice fireworks. They might measure ok at low voltage, but who knows if the insulation would hold up after that torture.
The "K" shaped capacitor vent is Rubycon. The "Y" shaped vent is Nippon ChemiCon. I think the wax trick is because it's self levelling, when they heatshrink the new label on it, the wax re-melts to fill the voids. I'm also looking at this bridge rectifier mains side, and wondering, will it really survive 600W of power draw, entirely without heatsink? I have not seen unheatsunk rectifiers in PC PSUs which are anywhere near this powerful. I suppose it will just about work in 230V region, but what about 115V region? The total mains current is doubled, and it's carried by only two out of 4 diode elements, so each carries 4 times the current, this seems very dodgy! The thing that is most scary about PSUs i think is ultimately the magnetics, you rely on the transformer to separate you from deadly mains. I almost hope that the transformers are salvaged from something good, but they can take damage with time too. Transformers must be the by far most expensive components in the PSU to manufacture, and even more expensive to QC properly. There are cheaper, safer and more trustworthy 12V PSUs you can get for the power. Server power supplies, like from Hewlett Packard and Dell, usually 600-800W. They come from a redundant array and have a card edge connector, they're written-off or decommissioned units, sometimes they have faults in PWR_OK circuit or something of the kind. They're guaranteed not to have run more than a few years, they are taken out of the array before they are expected to possibly fail. If they're manufactured by LiteOn, then they have a fairly tolerable, temperature controlled fan, if by Delta, then they get loud. Also some get loud because the fan control circuit has died. The manufacturer isn't printed on the PSUs, but can be found by E-number UL search.
The bridge rectifier is definitely not the biggest concern. Many older ATX power supplies had it with no heatsink. Some even had just 4 flimsy diodes. The fan also helps a lot. And if you run it at 115V, there's always just 1 diode voltage drop, instead of 2, besause the 115V switch turns it into a doubler. So the power dissipation of the bridge rectifier is the same for 115V and 230V.
For those who are not familiar with these products: A) Always multiply their Watt rating indication by the correction factor 0,48. Thus the Chinowatts are converted to Realwatts. B) Further derating of the output power might be necessary, depending on the ambient temperature and humidity of the installation place. As a rule of thumb, use minus 30 Watt per degree Celcious, above the 18 degrees C ambient temperature. C) There is nothing wrong with their waxed caps. It's merely an innovation of the Chinon Shiticon, the original manufacturer, used in order to destroy their competitors. D) Always wear protective glasses when you see these caps working. They tend to explode unexpectedly, if you stared at them...E) Enjoy your buying preference safely and happily!
i gotten a few of similar power supplies, and yes ALL those parts are recycled, those capacitor are recycled from returned or failed units were they clean em up and re wrap the skin on em, plus all those parts are off the shelf components you can get em in bulk for under 5$, its not surprising that parts look similar or slightly off cause there grabbed from a bucket in a factory. i work for an electronic company and we find these trash parts "new" from china but there just salvaged from rejected parts. also those boards you can get for 1$ at PCB factories there a common board that you can get as you can use that board in that video for 12v 20amp 220watt to 600Watt as you then need a bigger board to add more Moffsets and 2 more rows of capacitors. However this is the first time i seen the wax fill, as most would use pliers to press em back into shape as you peel the skin off the cylinder has tool marks and rust spots from old tools and there metals touching the bare tin casing. Anyways good video, love seeing someone looking into these power supplies since there are soo many of em and there getting harder to find quality ones.
RoHS and CE certification on the label of course. However, in the case of products from China, this means Risk of Huge Scam, or also Risk of Horible Shit. Chinese Electrocution.
IMO those big caps were of two different manufacturers, forcefully ripped from some appliance with pliers (there's no time or money for solder irons somewhere it would seem), ripping away paths; then their outer plastic film torn away, dents filled with wax and reskinned with some other plastic film, then tossed in a generic bin of caps to be used as parts. I'm actually surprised at the fact that they didn't give completely different capacities than those declared. if we're talking about recycling electronics parts I'm all into it, but should be some basic safety or quality issues to be taken care of. I guess you get what you pay for, and I'm aware of the fact that "safety" and "quality" are things that some people give absolutely no Fs about.
Wax doesn't make any sense to me. I'd think that it melts when they apply heat to shrink the fake cover foil on. So much extra work when they could just have desoldered them with a little bit more care and inserted them in their original state instead. Undamaged old and used caps would be so much more trustworthy than damaged old and used caps disguised as fake quality ones.
There are probably different price grades on junk pulls - nicely pulled ones would plausibly cost more, someone messed up and fixed up the issue as best they could to still shift the product and not be stuck with just trash on their hands. Ultimately the PSU manufacturer didn't care what they're buying, counting on nobody actually looking inside, because i mean the first thing that you should notice are two different batch transistors with the same type.
I don't get it either, same story with how they pull chips out of sockets and then throw them in a pile, dunk them in solder, and sometimes remark them instead of giving half a shit about safe handling and selling them as the as is pulls they are. I understand the concept of dishonest practices for profit, but they'd almost certainly make more being honest here, between the reduced labor and guys like me who demand a refund when I buy "new" and get recycled shit.
@@SianaGearz I don't even understand how you'd need to apply such force to extract the capacitor while desoldering. Unless they actually just force-pulled it without desoldering?
@@MrCh0o Some of them extract components by holding the PCB over open fire. Because everything is so hot, it can be difficult to get a careful and accurate grip on things, they must be holding the board with one set of pliers and extracting components with another. And capacitors can be in pretty well, legs can be splayed due to hand placement and they're also a little chunky, it's those rivet legs.
More reason to thoroughly test components bought from china. I remember spending sleepless nights on a particular project, only to realize some of the jumper cables I bought didn't have the copper wires in them. At that point all I could do was laugh, I couldn't even be mad. Dented capacitors filled with wax huh!😅
Hello, sir can you please teardown a HP or such server PSU, those are noisy but very reliable, so if you please explain those that will be really helpful. Chinese wax smoothing was a delight to watch.
This is the best video you ever made. You really made my day. Super cool and I love you "bloody hell" I am an electric engineer and I often wonder why the Chinese have a good design but totally failed to build it properly... take care and carry on making those videos 😉
I was writing a comment to try to persuade you on talking about the output ripple of this PSU (I have a similar one) and maybe some ways to make it better. but I see I am an hour and seven minutes too late...
I don't understand how that outputrectifiing works with that two diodes but only one secundairy winding(as shown on time 4:59). That second bottom diode between gnd and output, in a way it must always be off, that one makes no sense to me, but i see it always done that way. So why ??
The lower diode at the output of a 2 switch forward carries the current of the output inductor when the transistors are off. It works in a Continuous Conduction Mode (CCM). There's always a current in the output inductor, it just ripples a bit. The current goes through the upper diode when the transistor are on, and through the lower diode when the transistors are off. And strangely, the lower diode sees a higher average current, because a 2 switch forward runs below 50% duty cycle.
It is most likely a center-tapped secondary. One end of the winding is at +12V while the other is at -12V, center is ground. This way you get output current all the time and only half the voltage drop as you would with a bridge rectifier.
@@robson6285 Ah I didnt pay enough attention. I thought it was a halfbridge topology, not a 2-switch forward. Also, Diode's answer wasn't there yet when I read your comment.
I don't think i would trust the whole thing untill all the capacitors were replaced with decent ones. And the bad heat sinking of cause. I would not trust it at 50 amps, 20 amps would be my expectation. They lie about the parts, so nothing stopping them doing the same for the maximum current. I'm sure you will make it good and reliable :-D
those capacitors are hilarious. i wonder if they are third hand parts. like they took them out of a device that in turn salvaged them from another. it makes me wonder what the highest number of times a component has been salvaged from one product to another and still works in the final product.
Excellent video, a lot of these kind of power supplies generally look fairly well made for a Chinese product, however this particular one looks much more cheaply made then the usual low quality ones from China.
I bought mine (60w 5v) power supply, and there was a 1-3mm wide string of thermal paste going from the transistor to the diode. Also it squeled so bad my ears were hurting.
Interesting: It has a CE mark on it. The CE mark may be applied by self-certification, i.e. the manufacturer just claims that the devices is compliant with all relevant regulations of the european union, you don't necessarily need a test by a certification lab to apply the mark. But as far as I know, one of the relevant regulations for power supplies (should apply to this one as well) is a minimum power factor of 0.8 or 0.9 (or something like that) which can not be achieved without some kind of power factor correction. I don't see any power correction efforts on that supply, though. This means the CE mark is most likely undeserved.
Thanks. I am getting used to your Pulse Swiss accent. That's fine. Have a nice day! ⭐⭐⭐⭐⭐ edit: in a previous vidéo, when he says Pulse Width, you can hear Pulse Swiss
Wow, so they used wax as a filler to hide the fact that the caps are not only reused but abused as well. They could have got away with it perhaps if they did a better fill job. Perhaps the wax was supposed to melt a bit with the heat shrink application.
I like how he seems to have complete disregard about where the screws fall to when unscrewing power supply covers It's like the Spiderman meme about taking naps. Will it fall inside the supply? Will it fall on the table? No one knows, and that's the fun of it
I recommend you Google for HP/Dell server PSUs. Here in the UK you can buy good quality HP server 12V PSUs rated from 460W up delivered for cheaper than this, and the capacitors don't come with dents!
I learned that i shouldn't buy powersupply from China, it's better to buy used server powersupply (in case if you need 12 volt and 50 or more amps). Server powersupply is more relaiable than this junk, because server powersupply is designed to work 24/7 and they have all original parts. For 20$ on Ebay you could get used 800 watt server powersupply.
A wax filled capacitor... the chinese never disappoint 😂 Would've been nice to see the power supply working since paraffin starts melting at 50C 😀

600W of power draw. That's less than 3A on 235V or so with 90% efficiency. Bridge rectifier is like 15A one.
As I understand its desirable to run rectifiers kinda hot as the forward voltage goes down (and efficiency goes up) as temperature increases.

Server powersupply is more relaiable than this junk, because server powersupply is designed to work 24/7 and they have all original parts.
For 20$ on Ebay you could get used 800 watt server powersupply.
