yes, they were paying your years of knowledge. If the customer know how to, they can do the job themselves. I have a lot of customer where when I fixed the "common issue" and they want it to be fixed free of charge, I usually tell the customer first hand the rate before checking the issue, even its as simple as a driver update or settings, I will still charge minimum charge. if the customer argue, I will just tell them why send it to repair if you know how to fix it yourself. don't give free service, it makes them want more free service.

Agreed, you definitely need to consider time and experience in the cost of repairs, given the capacitor itself is only worth 10 cents, and you do get a clean, new thermal paste and pads for a good as new GPU. With the price of new GPUs these days, repairing a decent GPU is very worthwhile.

This is why dual rail and quad rail PSUs should be preferred. They are harder to build with, but it's worth it. They are now executed as virtual rails, so each 12V rail gets its own OCP circuit, but the power for them is common.
@K31TH3R

That's not bad advice, and yeah, the key takeaway from this mode of failure is definitely a lesson about always using a quality power supply in your builds. I had a similar failure when I had a GTX 980 Ti blow up it's #1 core VRM phase while it was hooked up to a subpar Enermax Triathlor Eco 1000W single rail PSU. OCP did eventually trigger, but not before it melted PCI-E cables and came close to starting an electrical fire. The irritating thing is that modern high end GPUs now have such high transients that it's difficult finding a multi-rail or virtual rail PSU in multi-rail mode that doesn't get an itchy trigger finger with OCP when you're running overclocked GPUs that can burst load to 600-700W. I needed to swap a nice multirail Seasonic Focus 850W out of my build for a single rail eVGA G6 1000W because I have an OC'd Liquid Devil 6800 XT that would constantly trip the OCP with the Seasonic unit. The G6 on the other hand just doesn't care at all, but now I have to do a "trust me bro" that the OCP is tuned right in the G6 in case something goes wrong.

Very grateful for people like yourself who do GPU repair - just found out my 2080ti is on it's way out , crashing under load after 5 minutes with artefacts suddenly starting yesterday. Spoke to a UK based tech (Matt @b-Hawkgaming) who said the memory controller has been literally fried (a hotspot so subtle it's not picked up on monitoring) :/ , guess I'll be getting a 4080 Super earlier than planned... I'd have reached out to you if you were UK based my situation. As for this video - I'd not be too worried about it being a short fix - the amount of expertise you need to repair these things is very high. My educated guess as a viewer on my own card was that the solder balls under the core was degraded and with thermal expansion was causing the core to disconnect from the memory channels , but you can't beat actual repair experience - I had no idea about the hotspot issue before talking to him.

This wicking difficulty is exactly why I pull out the legs using some heat, and then plop a microdrill bit into my screwdriver and carefully bore new holes into the solder - just enough for the new legs to pass through. Generally gets the job done way faster than any solder sucker 9000, I'm not even talkin wicks. Too bad this technique is mostly forgotten in the age of SMDs. Also this trick can be used for some orifices, which you need to have bone dry, but they're just denying to cooperate. A hole is drilled, packed with flux, and when you apply the wick and some heat - boiling flux does it's best to push out as much solder as it can. Works better when the heat is applied from both sides.

Aluminium has high reflectivity and probably that is why it was hard to see it heating up. One thing I would not suggest promoting is that lowering the amount of caps is OK. It is not OK, manufacturers optimize cost by using the lowest number of caps and if low quality caps are used, then they will start slowly heating up and dying one by one. Therefore you should always replace them with at least similar ones!

All atx psu specially those over 250w has over current protect on every rail it's just how they implement the ocp, some has multiple 12v rail that's just derived from a single 12v rail in the psu, those are the safest psu as each 12v rail has its own ocp value meaning the total power where divided, like for a 1000w on 12v rail devided on 10 rails, each will trip at just over 100w, instead of a psu with single 12v rail, that will keep shoving all it's current until it's exceeded it's total capacity
@sakaraist
@sakaraist 10 ай бұрын
Not quite, OCP is typically only present on multi-rail PSU's whereas OPP is used for single rails. It's also not a spec REQUIREMENT and only a recommendation for to meet ATX standards. There's a fair few notorious PSU models from big manufacturers that have literally been fire hazards due to a lack of OCP. (Also nitpicking a bit, but it's technically VA instead of watts. They can be the same but they can also be significantly different values from eachother depending on the power factor)

These are there because of peak load capacity and handling worst case scenarios. You can get away with the missing cap, but it carries a theoretical reduction in its resilience to issues like badly regulated power and long cables causing high impedances. In practice, one missing capacitor on the bulk array will be unlikely to give you issues unless you subject yourself to those worst case scenarios.

Have been using a PNY 3070 for over a year, great card at least in terms of cooler design. Same cooler as the one in this video. Don't see a lot of PNY 3000 series cards make it to Tony's bench. There's another one called "Cheapest 3080Ti fix ever" that's a good watch. From what I understand Palit / Gainward actually manufactures the coolers for PNY, and PNY mostly is known for making Nvidia Quadro cards. They have been around almost as long as Nvidia. Their XLR8 cards seem pretty decent but they ain't no EVGA. Also I've heard mixed reception about their warranty service. Personally I don't really care. I just want my card to have a good cooler design for a fair price so I know it will undervolt very well, anything else is just whatever. I would probably buy another PNY card over a poorly-designed and overly expensive MSI or ASUS card and PNY has done well with 3000 & 4000 series at least in terms of cooler design. Big heat sink and lots of thermal paste & pads. They don't really give them big boost clocks though like some of the other brands. All in all PNY is alright. My opinion might change if my 3070 dies suddenly in the next 2-3 years lmao.

@SianaGearz
@SianaGearz 10 ай бұрын
It's very common for lower-tier-brand PSUs to have OCP/OPP that doesn't actually work, because the trigger current is set way too high. This was for example the case in that explodey Gigabyte PSU, you remember, GN covered it. Of course the reason it exploded there wasn't that, but that didn't help. Anyway i suggest you look at Hardware Busters. Of course even a mistuned OCP/OPP circuit will trigger on a really strong short circuit event, and usually before the wires melt as well, but the hazard are near-short events where there's just enough accumulated resistance along the circuit to not trigger it, but already enough to melt the wire harness. Such a bad cap would be exactly this kind of near-short condition. The primary fuse doesn't help, because it's there to protect the supply cable and the primary side of the PSU against catching fire, but it must also allow for the very high initial current of charging the hold-up capacitor(s), the really big ones. So it's rated way higher than the operating current. Then you have the issues with fuse sizing - at rated current, a fuse only survives for typically 4 hours, burns out, so you have to overrate them by a lot if they aren't user serviceable, plus for a given output current, the input current is twice as high in 110V countries than in 230V ones. You're likely to see a 10A fuse there. You need precision trimmed active current sensing circuits on the secondary to have good OCP. PC fire is also a common issue when you have a PSU with a single 12V rail in higher power tiers, potentially more powerful than you really need. Because each individual cable might be rated for maybe 40A without catching fire but your PSU is let's say 60 or 80A capable. A solution to that is a PSU with virtual 12V rails, where each rail has a separate OCP. At 550W, you might not need virtual rails at all, at around 700W i think 2 rails are a good idea, above you should demand 4 rails. Building with these PSUs is a little tricker, you have to consider where you plug things in, since if you have too much stuff hanging off one rail the PSU will go into protective shutdown in regular use, but that's an entirely safe failure mode. But people are by and large incapable of reading manuals and following instructions, you see the issue? Back in the day, Corsair's marketing went big on their single-rail high power PSUs, and they don't get any brownie points from me for that, for deleting a safety feature and making people think it's better like that.

There are some 'slow glow' situations where things just get hotter until they start fires. In terms of a core or cpu, I always thought they would halt on corruption, or blow the main fuse. So the problem is almost maybe in the other components?

It can only halt itself if it isn't shorted. A severe short circuit will cut power to the rest of the chip.

if the circuit is not protected and there are no fuses in place, then circuit will determine a fuse for you. my teachers said something like this

been hearing about those IEC cables melting down a lot lately, I even have had acquaintances have their cables melt. The cable should be decent enough to pop even a hefty breaker during a short, I suspect some cables are a lot cheaper than they should be these days. I wonder if the power supply experienced SCR lockup while the cable burned out and that dumped 90v into the card and shorted the cap

I burned one up on a bench test power supply recently. Methinks some cheaper-by-the-dozen manufacturer made them too cheap. Fused power socket saved the tester, but the power strip and IEC cable will never be seen again.

What about PC mainboard etc, you can't just attach more than 25V even for a few milliseconds without receiving firework greetings from various numerous components. GPU as well, it wouldn't just be one shorted cap.

@@PeppercornVR I think a single shorted cap and nothing else being wrong is a strong indication that this is all that was wrong, a single cap that left the factory with a hidden defect; where it had to cycle for a while until the insulation broke. Sometimes a small metal particle becomes lodged in the insulator and eventually as the cap breathes, the oxide layers grow and shrink, it may have broke through.

@@SianaGearz I was really thinking about the board and cpu that failed after the cable burned through. I suspect the cable failed first and the lockup killed the parts. It's probably equally plausible that a failed component and no ocp took out an already damaged cord
