Not everyone lives in the USA and pay in USD. For us in South Africa, a 4090 is six months salary. So, we either get the card, dont eat. Or better idea is stay on an old card and have food. Basic salary is ZAR6000 -ZAR8000 here. the 4090 is ZAR32000 -40000

No, it's about 300 watts for the core, the rest goes to the memory and VRM and PCB losses. Peak efficiency for this VRM is at about 234 amps. This is a budget card though. The Mid range cards have the VRM running at peak efficiency at 300 amps
I always find your fixes very fascinating and entertaining. I have a PNY 4090 so it was interesting to see what it looks like under the hood. I hope nothing bad happens to it. 🙏
@boofygoofy3758 I used to upgrade every cycle to the top card until I got my Titan XP. Had that for 6 years and it was great. Then tried out the 7900XTX. Had it for 8 months but they had some serious issues with VR. Somehow managed to get a full refund as it started to die and then I got the PNY 4090 instead as the strix was 2200usd and the PNY was 1700usd.

Clicked on this because I have a 4090. Aaaaaaand my case is open. If that liquid was a dog whiz, I better get my case cover back on before my dog gets that email! Thanks for saving my GPU!
very satisfying to see those cards to be saved instead of being reedeem to a no fix for economical reasons . I takes a lot a knowledge too, breat job !
The AIBs cutting costs because nVidia charges them arm and a leg for the cores, same time dictating the MSRP and competing with them making founders cards. This is shady AF! Even my fav PNY can't last in that environment 😢😢
I mean they do produce the most important product on that measly board. If I was in NVidia's shoes I'd do the same. but the real reason AIBs cheap out is because they want to make X profit per card and don't care what the consequences are to the consumer
@@iamdmc Spilling electrically conductive liquid on your card is likely to damage something no matter how good the quality is. Some cards have more robust designs which will reduce the amount of damage they are likely to take, or just make diagnosing the problem easier. Not having soldered joints on the heat sink isn't necessarily a big deal. The cooler for a 4090 is going to be so heavy either way that you should never mount it horizontally (in a vertically mounted motherboard) without some kind of additional support, and you should never transport the card in the slot without additional support either. Even if it's the lightest 4090 on the market, you probably still need to always give it additional support, unless it's mounted on a horizontal motherboard (but even then you wouldn't want to transport it without removing the card first, or adding additional support). I didn't watch the entire video, so unless there's some additional design flaw that he brought up deeper into the video, the quality doesn't seem to be an issue here. Spilling electrically conductive liquid on your card is likely to damage something no matter how good the quality is. We should be picky about quality, especially with an ultra-high-end product like this. That being said, quality for videocards has generally gone up over the years, but sometimes quality does still go down too with some brands. Personally, I have become very picky. I don't care about extreme high-end over-engineered coolers, I just tend to go for coolers which are above the quality of the more basic models, and I like to see independent reviews on the exact model before buying. Sapphire and EVGA both offered a lot of good quality boards without charging a big premium for it, but sadly EVGA obviously isn't making cards anymore, and Sapphire obviously only makes AMD cards. Most brands make some good products, some over-priced products, and some products with design problems or quality shortcomings. Manufacturing flaws are also always a possibility, even if the design is perfect.
A good method is to inject the voltage e.g. on 12V, but connect the ground lead to a coil behind the mosfets. That way you can safely apply higher voltage and it won't run through the core.
th-cam.com/video/ZaxBuEYOkNo/w-d-xo.htmlsi=UWkWlD4ZvfbwQwa2 It was also explained in details on Learn Electronics Repair channel, one of the videos on short detection methods.
i dont get one part ... how is possible 1 voltage injected get leaked through doctor mosfet and leaked 1 voltage ??? doctor mosfet needs a minimal voltage to get activated close to 12 voltage IN , doesn´t ???.. i dont get that part
This repair was incredible, I wonder how much would cost this level of a repair. It gives me hopes that people can still repair things that's why I loved seeing this video is atrocious that we are all forced into a culture of disposable electronics when there could be more effective than effort to extend the life of equipment like this.
amazing repair! One of the few techs using a preheater instead of blasting 1000F to cold boards. One thing I wonder - not really expecting an answer - is how much you charge for such a large job. Fair enough the 4090 is an expensive card but that was a lot of work! Well done anyways!
Unfortunately the cost of reparing stuffs went so high that most of the times it is more logical to put a bit more money and buy a new device instead of reparing the current ones. no doubt repairing things is difficult but at the end the cost should be so that people think it is worth it to pay for repair instead of getting a new one
Jeesh captain, the board would not release even with low melt solder. We might need some way to pressurize the molten solder. Like that Philippines guy on shop fix channel. I watched him give back a graphics card to a customer and the memory chip he had used solder wick to pick up all the unleaded solder from the board but he left it on the chip. I think he never had a stencel or solder balls. The card then worked fine but might crack at the first opportunity.
Having a vapor chamber instead of a copper plate is a huge advantage. I heard a rumor that Nvidia was thinking of making the 4090 even more high powered but then they changed their minds after the AIB's already had their coolers in the pipeline and that's why they're so overbuilt. Maybe PNY skipped soldering to save some money because they knew this cooler would work fine.
They get away with because people just don’t know until they see a video like yours. People assume it’s made correctly especially if it’s from a big name company. So it’s good you show this kind of stuff. 👍
You always seem to amaze a lot of us good work for sure. I would like to see you go more in depth on the builds of these cards with components and such to give us all Insite on to which are the better cards.
11:35 those artifacts are just, poor switch quality?? i've had that on my hdmi tv for a while and i thought there was something wrong with my graphics, good to know it's something else.
I mean it's a 4090 so probably not but I would expect a repair like this to cost $300US or more just for his time, + $50 for parts Replacing RAM will cost even more, like $20/chip, and if your core is dead (on a 4090) that's the thing that "totals" the card because a replacement is basically impossible to find brand new commercially, with used cores off of burned out cards being the only option (and such a card on ebay is about 1/2 the price of a new card)
Awesome video, I liked a lot that you put exact temperature numbers in the text, that is neat for begginers like me. I hate that connector too. Small pins are a pain if they get bent, had to replace one with the same procedure as you did.
haha your humor cracks me up.. nice one.... like that one. lots of small details included. one day ill get lucky and get fired to. So much to learn even with advanced soldering skills and electronic background . it would help if I picked a specialty.. but i want to fix it all!!!!
love to watch your fixes...its a kinda relaxing mode to me. you do such many great jobs. !! if some day i need help ill send my hardware to you for sure ! Hope never need, but in case your my Go2Men !
Why is the 12 pin connector looking like it is being pulled to the right ( @11:48 ), it looks to be a good few millimetres from properly seated. Those 12 pin connectors really need to be changed for a better design. Well done for fixing the card, it really did not want to be repaired.
@@carrickdubya4765$1600 is not cheap no, but out of all the 4090s it has the lowest price and it goes on sale more often than others. Also its often found used or open box. I got my PNY 4090 for $1200 open box (looked new), only thing missing was the support bracket. People do say it has the lowest quality out of all AIBs but mine has been running great, no cool whine and good temps.
Is 180c (preheat) board temperature safe? The capacitors specs says they are rated at max 105 celcius. I am always feered to preheat the board above 120c, cause they are has some liquid, and dont want to blow then up :D.I should test cap capacitance before preheat, and after preheat on different temps.
@@northwestrepair*depending on the problem with the 4090! If it's a dead GPU core then probably not going to be worth it vs buying a new card. If it's a few mosfets to replace or even some GDDR6x chips then maybe worth it - just. However you'd still have no warranty on the 4090 afterward (from a manufacturer I mean)
If you're buying a broken 4090 just to send it to someone for repair you're retarded. That card was already at a shop and unless it wasn't diagnosed incorrectly it has a dead core.
Great Video and again, great on screen tips while you are working. Curious if you think a desolder tool would have helped you with that connector replacement.
Question, if that mat you are using, is anti static, Isn't it also conductive? And won't that influence the cards you are injecting voltage into/measuring? Or, is the resistance of the mat too high for test voltages, but conductive for High voltage/static? hm...
its not anti static. Anti static mad is not conductive. It has a wire which you strap to your self which is grounded. Thats all that is. Just strap your self to ground with a coiled spring like wire so you are not restricted in motion.
A good way to desolder the connector without damaging it: solder a wire that connects all the pin on the back of the card, like a snake. The cover it of leaded tin and then apply hot air on it: the connector will fall down easily.
im curious, is everything around the chip sort of feeding it and making sure it gives what the chip needs to perform optimally? and are the parts (except the chip) replaceable? sorry i have no idea whats going on but its very fascinating to see
I have a question, Have you repair any PNY graphics crads?, And if so how good is the assembly and quality?, I want to buy a new GC and the fact the PNY are up to 100 ddl cheeper is very alluring, but it also makes me suspicious of the quality, I know price is not all but still
You shouldn't look for general opinions. Every company makes cheap models that are usually very bad and high end models that are usually pretty good. Some are better than others but it changes from generation to generation when companies are revamping their cooler designs. PNY XLR8 on the 4000 series has one of the best coolers. Asus Dual on 4000 series when switched to quiet bios is also pretty quiet and is probably the best you can get at msrp.
I have exact the same 4090 from PNY and I love it. the card is way better than the 500€ more expensive 4090 Strix from ASUS I had. I know the PNY is "only 450W" compared to the Strix. But the ASUS had horrible coil whine and also noisy fans compared to the PNY.
Lol ik the feeling I have the 4090 gaming x trio tho the vapor chamber would be nice but truthfully not really needed lol I barely hit 70c on full game loads and that's with it vertically mounted I know this owner 😂 gonna turn over a new pcb after this endeavor and treat their card better xd.
I am so happy that humans still have their place. The manufacturing is so complex that it is a shame to just throw those gem stones just because some transistor went rogue.
Good video, I feel a bit sorry for the end user though. Send in a repair and it takes over a month to get it resolved and sent back. Assuming there was a bit of a backlog and assuming opening/shipping time, was it about 1.5 months? That's a long time to go without a video card. Having a few of each part makes the most sense. Grabbing just a few of each would save the customer a lot of headache if something happens in the future.
In a perfect world, sure. Keeping a rolling constant stock of various parts would be amazing, but lets be honest.... we all saw how every big mega corp couldn't do that not too long ago (some are still fighting with supply lines) Not under the impression he's running an operation that big lol.
Tony, I noticed how much solder you use to tin the pads on the PCB and the MOSFET. Do you think that so much solder could possibly lead to shorts under the chip especially after pressing on top of it ? When I do similar soldering I'm always very cautious and I use wick to remove some of it.
KrisFix seems to have a soldering iron with a vacuum or something - I never see him using Solder wick Considering how many GPUs you fix it might be a worthwhile investment? Also you'd have a lot less lead exposure since there is no premix step
KrisFix is using unleaded solder IIRC, so lead exposure shouldn't be a concern there. I'm not a repairman, but wouldn't want to go anywhere near leaded solder fumes.
@@szaszm_ yes but the OP NWfix does use leaded solder. That's why I'm saying the solder vac might be a better idea for him to avoid solder wicks and leaded solder fumes
Warranty is for stuff the OEM did wrong. You're free to take a sledgehammer (or water hose) to your card, but the OEM will not take any blame or charge for that - and rightfully so, this kind of damage is not their problem. The OEM might offer to repair it for you for a cost, outside of warranty, but that's something else. And I suspect that no manufacturer would touch this card in their shop, the damage was more excessive than the typical one or two broken components they deal with.
Damn that repair was above and beyond. Great work.

4:29 Maybe the "top" is not correct 😶
Was it worth it ???? Compare Purchasing a good used unit and cost of your repair ????
This is really interesting to watch. You sir are a pro. 👍
Is 180c (preheat) board temperature safe? The capacitors specs says they are rated at max 105 celcius. I am always feered to preheat the board above 120c, cause they are has some liquid, and dont want to blow then up :D.I should test cap capacitance before preheat, and after preheat on different temps.
How much and average do you charge these 4090 repairs? Thinking of buying a bad 4090 and having you repair it, but want to see if it’s worth it..
It's worth it 😉
@@northwestrepairthanks for the honesty.
@@northwestrepair*depending on the problem with the 4090! If it's a dead GPU core then probably not going to be worth it vs buying a new card. If it's a few mosfets to replace or even some GDDR6x chips then maybe worth it - just. However you'd still have no warranty on the 4090 afterward (from a manufacturer I mean)
If you're buying a broken 4090 just to send it to someone for repair you're retarded. That card was already at a shop and unless it wasn't diagnosed incorrectly it has a dead core.
Great Video and again, great on screen tips while you are working. Curious if you think a desolder tool would have helped you with that connector replacement.
Question, if that mat you are using, is anti static, Isn't it also conductive? And won't that influence the cards you are injecting voltage into/measuring? Or, is the resistance of the mat too high for test voltages, but conductive for High voltage/static? hm...
its not anti static.
Anti static mad is not conductive. It has a wire which you strap to your self which is grounded. Thats all that is.
Just strap your self to ground with a coiled spring like wire so you are not restricted in motion.
Liquid damage, AKA a fat cluster bugger.
Are these boards created in the factory with the same method? I mean by hand and hot air?
Given that EVGA is out of the picture, what is the Nvidia partner with the best engineered cards?
How do folk manage to get liquid on desktop computers?
I wonder if such water damage common among those cards
Still need to know what that liquid is.
By any chance are those mosfets from aliexpress store with smush text on the images?
A good way to desolder the connector without damaging it: solder a wire that connects all the pin on the back of the card, like a snake. The cover it of leaded tin and then apply hot air on it: the connector will fall down easily.
im curious, is everything around the chip sort of feeding it and making sure it gives what the chip needs to perform optimally? and are the parts (except the chip) replaceable? sorry i have no idea whats going on but its very fascinating to see
hey! got a question, what microscope do u use? thanks for all the videos and amazing work!
Is there any way to modify press-fit fins with solder?
Now that's a lot of moving parts!
How is PNY 3090Ti? They looks like Manli. Does it worth to buy?
Is it the overclocking gpus that causes these blow outs???
When I run the game the screen goes black and goes into power saving mode
Cpu and gpu temp normal max 72c
Sorry for my ignorance, but the problem was that f... connector from the beginning?
You're Great!
because the price for a nvidia gpu is 80% of the actually card so they cut quality from some area
wait, you can wash the entire circuit board for deep cleaning service?
Insane and awesome job man, wish i had the technical skills you have to repair gpu's. There's literally no such thing in the UK.
You are Amazing
I have a question, Have you repair any PNY graphics crads?, And if so how good is the assembly and quality?, I want to buy a new GC and the fact the PNY are up to 100 ddl cheeper is very alluring, but it also makes me suspicious of the quality, I know price is not all but still
You shouldn't look for general opinions. Every company makes cheap models that are usually very bad and high end models that are usually pretty good. Some are better than others but it changes from generation to generation when companies are revamping their cooler designs. PNY XLR8 on the 4000 series has one of the best coolers. Asus Dual on 4000 series when switched to quiet bios is also pretty quiet and is probably the best you can get at msrp.
How much does this kind of repair cost????
Serious Question Why do all A.I.B's not cover the rear of the die?
The Nvidia Founder edition card has that place covered up.
i noticed your using < 1000w hot air station, is there reason for that?
I have exact the same 4090 from PNY and I love it.
the card is way better than the 500€ more expensive 4090 Strix from ASUS I had.
I know the PNY is "only 450W" compared to the Strix.
But the ASUS had horrible coil whine and also noisy fans compared to the PNY.
Lol ik the feeling I have the 4090 gaming x trio tho the vapor chamber would be nice but truthfully not really needed lol I barely hit 70c on full game loads and that's with it vertically mounted I know this owner 😂 gonna turn over a new pcb after this endeavor and treat their card better xd.
Liquid cooled CPU cooler leak?
Can you make a video on how to check any gpu voltages on gpu board 12v 5v 3.3v 1.8v carefully
Saving Graphics Cards One At A Time. 👍Good Job Mate.
Where do you find this synth wave background music? It's one of my favorite things about your channel and videos!
I am so happy that humans still have their place. The manufacturing is so complex that it is a shame to just throw those gem stones just because some transistor went rogue.
Alex is like like ahhh so this is how you do it
Good video, I feel a bit sorry for the end user though. Send in a repair and it takes over a month to get it resolved and sent back. Assuming there was a bit of a backlog and assuming opening/shipping time, was it about 1.5 months? That's a long time to go without a video card.
Having a few of each part makes the most sense. Grabbing just a few of each would save the customer a lot of headache if something happens in the future.
In a perfect world, sure.
Keeping a rolling constant stock of various parts would be amazing, but lets be honest.... we all saw how every big mega corp couldn't do that not too long ago (some are still fighting with supply lines)
Not under the impression he's running an operation that big lol.
Love your videos. would love to be able to do this myself.
Mr. Wizard did it again, 4090 saved after obviously a water cooler leak 😅
Tony, I noticed how much solder you use to tin the pads on the PCB and the MOSFET. Do you think that so much solder could possibly lead to shorts under the chip especially after pressing on top of it ? When I do similar soldering I'm always very cautious and I use wick to remove some of it.
I think yes a bit too much solder and it jumped two or more pads when he pressed down.
I've known people that were Stupid enuff to actually Piss on stuff to see what would happen! The results were extremely Hilarious😜!!
Northridge fix sells those connectors i think, you could've gotten them faster
And 20 times more expensive
I have a 4GB AMD. Its having a problem of power connect, I remove it and now its not working at all
Can you please help me
0:14 the duck omg bwahaha 🤣
Yep, had to go back twice to see what it was.
KrisFix seems to have a soldering iron with a vacuum or something - I never see him using Solder wick
Considering how many GPUs you fix it might be a worthwhile investment? Also you'd have a lot less lead exposure since there is no premix step
KrisFix is using unleaded solder IIRC, so lead exposure shouldn't be a concern there. I'm not a repairman, but wouldn't want to go anywhere near leaded solder fumes.
@@szaszm_ yes but the OP NWfix does use leaded solder. That's why I'm saying the solder vac might be a better idea for him to avoid solder wicks and leaded solder fumes
@@iamdmc yeah I agree
When the Coke Can strips come out you know some serious shit is gonna happen
Just out curiosity what does a repair like this cost?
Why you dont test them before you open them?
"Testing" anything with liquid damage would be really stupid.
insane repair, good job!
Still using my 980ti classified and it's still a beast
What gets me, usually these cards have a mfg warranty. does pny not honor any warranty after card malfunctions?
Liquid damage. Their warranty covers defective components not user damaged components.
Operator error not covered.
Warranty is for stuff the OEM did wrong. You're free to take a sledgehammer (or water hose) to your card, but the OEM will not take any blame or charge for that - and rightfully so, this kind of damage is not their problem. The OEM might offer to repair it for you for a cost, outside of warranty, but that's something else. And I suspect that no manufacturer would touch this card in their shop, the damage was more excessive than the typical one or two broken components they deal with.
Do you have a link to those extra long stand-offs that you use? Thank you.
They are stacked .
@@northwestrepair Ah, ok. Thank you.
Where is the piano cat?
Hi what did you study to do this line of work ? Pls
