LFC#190 - Intermittent 1080 Ti fault with obvious solution

I was fixing this build just before Christmas, and while it wasn't a super interesting solution, I thought I'd try a ramble video where I just waffle about what I'm looking at.

[@Adamant_IT]

FYI - So KZbin in its infinite wisdom has picked up this video to showcase my channel... This isn't one of my good videos. It was just a chill-out ramble video I made in the christmas wash - that week or so before Christmas when you've finished everything that needs to be done before the holiday and there's not much else happening. Another time I probably would've thrown out this video because as numerous others have pointed out, it's a solution I should've found in five minutes. Also the customer did swap out to dual PCI-E power cables afterwards - so rest easy on that.

[@lesleymunro4964]

I wouldn't throw it out - It did show a logical troubleshooting scenario, and the easy trap that newbies can fall into. It reinforces the lesson to check ALL connections, at both sides of a cable, before condemning a card.

[@Adamant_IT]

Also because it was a ramble video I didn't bother with a thumbnail :P However I did give DaVinci Resolve a go. The shortcut keys for it are frustrating, it's really really designed to be used with the Black Magic editing desk stuff. Also still no GPU accelerated exporting, which is really what I'm looking for.

[@MrWorsterLike]

Have you tried resolve again? GPU acceleration is now supported and export speeds are, in my opinion, rapid. It is designed with the BM desk and wheels but everything can be done with m&k (again imo) and shortcuts now have a few preset options, like after effects mode and vegas mode where common shortcuts are the same as they are in those programs.

[@Voidolt]

Please keep going making these videos, it makes me to learn a lot of stuffs even if i didn't build any PC's. Awesome video.

[@ytQrash]

The melting around the power supply pins at 32:20 is similar to the recent (late 2022) spate of issues regarding the PCIE 12VHPWR connector used with Nvidia RTX 40 series cards. In both cases the melting is caused by incomplete insertion of the power connection.

[@hmello3250]

except in this case it was actually unproperly inserted 😂

[@kamekaze997]

Saw your video on diagnosing shorts and then scrolled through your videos to see if I could find a repair that’s related to my issue and voila! This Xmas video is exactly what I’m going through. My 2080 ti fan spins at 100% and won’t post. Going to replicate exactly what you did here to rule issues with the power supply out. I had switched my card from PCIe slot 1 to 2 and it temporarily fixed my issue and now my card won’t post when starting it up cold. So I took the card apart and the original thermal paste application was poor so I reapplied paste. It worked temporarily when I booted it up but the next day it didn’t post until I let it run for a few hours and restarted it It’s currently working now but my computer won’t sleep automatically and it just stays on. I know as soon as I turn it off it won’t post. So thank you for your videos, tutorials, real world examples and I’ll make sure to spread the word.

Great video and yes this is more common than ppl realize. I had 2 come in in less than 3 weeks that had loose cables arcing and melting connectors, 1 was even on the cpu power connector. Ppl get lucky and all they needed was new cables. As a result of issues way back in the 90's the PSU is the first thing I inspect thoroughly and no not with a voltage meter lol.

[@MrMrl69]

[@rogerdanblad]

Always fun to sit and guess along... Once it posted on the other system I thought "hmm PSU-cables perhaps since the other card just used one 8-pin?". Such a great feeling when you're correct :) Great and fun videos Adamant! Consider me a subscriber

[@TheGauges420]

Tbh, I hadn't owned a pc in 15 years, since probably '03 or so, and built my first last year... I loved the whole process of it, was really quite enjoyable. The moment the card didnt light up though, and you putting in the RX 570 worked, it immediately made me think about the secondary 8 pin connector, and then that is actually the problem, I just figured it had been unplugged but that looked so much more serious lol.

[@HangingWithDan]

... its had a melted PCI-e port by the PSU that didn't fit in properly either way... he cleaned it up enough for a connection between the GPU and the PSU which got the video card working again... Very well done! Though, since this video was made about a year ago, I hope the customer who owns this PC got a new PCI-e cable replacements.

[@schlowe2003]

I agree with you on RGB... I think it's a great way to add some customization to each and every build. If you don't want it, turn it off. If you want bright and loud, turn it up. Good job on the power supply cables though, I know a lot of techs that would probably skip that step and recommend a new graphics card off the bat. Just be careful with that coffee around an open and powered system though. :) *Edit* Also - one of my new favorite channels, from a tech in the US. Keep up the content.

Yeah my first case/RGB ecosystem was Deepcool Captain RGB Pro v2 240mm Deepcool CF120 aRGB fans x 6 in a Deepcool Matrexx70aRGB, with Vengeance LED ddr4, but I recently switched to Corsair Crystal 680x and Corsair H100i RGB Pro XT 240mm with x8 QL120 fans and put Vengeance RGB Pro in my rig instead, because I just wanted unlimited options really lol.

[@typicalpctech6674]

Power supply issue, you just said it as I typed it. Loose connection or not enough real power going to it. Old video but, this is rather fun. I would put a volt meter in the + and - of "My" video power plug 8-pins to see the voltage and see what is actually going on. Customer's I'd be extremely careful and know what I'm doing (make sure the prongs can't touch or create other issues). My stuff is junk compared to a customer rig (no matter if it's cheaper quality or not, I don't want to pay for un-needed repairs. But BINGO you found the problem I bet. Ouch FORCED Entry, and bet it's zapped many times. Ouch! Power supply side look okay? I have to say, I really didn't expect to see that result for that issue. Expected the card to have some problem, but trying a different power supply would have led to seeing the problem (hopefully). Good call on 1st time build/loose plug @ power supply.

[@johnbovay8353]

I once had a properly plugged in SATA power cable develop an intermittent connection after 2+ years which caused what appeared to be a motherboard malfunction. A wee sprit of good electrical contact cleaner (that's safe for plastics and formulated with a tiny amount of lubricant and a water displacement) solved the issue. I've found that said CC comes in especially handy when trouble-shooting oxidized old components and rigs.

I didn't connect the power supply to the cable that goes to the wall lol thought I'd instantly bricked my system. But I'd of contacted the customer and have told him the error and he'd have to buy a new PSU

I was surprised how many mid to high end cases don't have 5.25" drives. I know I am in the minority here, but I absolutely still use optical media for both read and write (archive quality blue ray backups should be more common). I ended up going with a fractal define r5 even though it is old

a hard drive LED is most important! I had a bad sata cable for a SDD drive, and the hard drive LED kept going on full tilt which indicated to me that there was an issue with one of the 2 drives, -- after trying different sockets on the main board, the issue continued. Finally, once I replaced the cable on one of the drives, I no longer had a stuck drive (also had long boot times and the LED light went full tilt even in BIOS). Yes you want a HDD/SDD LED light. It is a good indicator if you are booting as well

[@Adamant_IT]

Yea. Indicator LEDs are a dying breed, especially on laptops. They're a lot like extra ports, people never use them - but when you need them, you _need_ them.

32:37 clearly, the connector is showing signs of heat stress, the likely cause being arcing, closer examination of the corresponding pin would confirm that. Either the PSU is not up to par in providing suitable power level -or- the connector was not properly inserted during the computer assembly. The cable will have to be replaced and PSU checked for integrity.

23:13 If you mount the radiator with the tubes down it may not look as nice, but it will reduce/prevent "splashing" sound and increase the lifespan of the pump. Because the way you are mounting it, air will collect at the top where the pump is and it might not get as lubricated/cooled as it should. That is, if that radiator has a pump at the input/output.

[@lesleymunro4964]

One thing I'd like to point out, you only used one cable to the GPU, with the two plugs on it. I'm not a fan of the small pigtails like that, as it puts all the current for the GPU onto one connector at the PSU side. It's not spreading the load, increasing the current on the pins at the PSU side, and therefore the heating. On high power cards (>200W) I would always use two separate cables from the PSU to the GPU, as it lowers the current on each pin on the PSU, provide more conductors up to the GPU, and generally lower any voltage drop to the GPU (And heating of the cables and pins). Not saying it can't be done the way you have it, especially if you are in a bind, but if you have the option, I'd try and use individual cables between the PSU and each GPU power connector. The pins are technically rated at 13A, if they are to Molex Mini-Fit Jr. specs, but then if you have a bad connection, or bad seating like in this case, that's gonna drastically reduce the current carrying capacity, and lead to excessive heating, as you seen here. Note to newbies - make sure your connectors are FULLY seated in the socket, or things start melting.

[@hellcat1988]

Not only what you said, but there is evidence that it can squeeze out just a hint more performance from the card when overclocking.

[@CorruptSec]

So true ^ i will never use a single cable for these kinda cards either :)

[@Soverax]

@Xcepter that depends on the PSU. With a 650W-750W you definitely need to split the load between the rails. With a 1200W I haven't had issues at any point running the Sapphire Nitro+ Vega64 powered by a single cable - undervolted/OCd. You are all correct however that it is better practise to split the power load with 2 cables, both for the PSU strain and GPU performance.

[@mihailstanev8867]

But you guys are missing the poin that the PCIe power might be split on 2 different rails and might have a small voltage difference that would stress the VRMs. Both cases have negatives.

[@Soverax]

@@mihailstanev8867 The voltage differences produced are usually negligible and the stress on the VRMs is hardly noteworthy. If you connect both PCIe cables to the same rail you are more likely to notice performance decrease / throttling due to the OCP rather than the GPU VRM. If you connect them to PCIe slots on separate rails you are easing the load on the PSU and literally just letting the VRM do the job it's supposed to do, and that's regulate the voltage. Considering the cooling of the VRM is adequate, which manufacturers make sure that it is, it is not a point to concern yourself with.

[@OthmanAlikhan]

Thanks for the video =)

[@-yeme-]

coming at this from a general electronics background, once a high current connector is arc/heat damaged it MUST be replaced before further use. even if the quick fix works that connection will now be high resistance, that means heat, that means potential for more damage in the future and maybe worse. at the very least I would have checked the temperature of that connector after the graphics test to see if its heating up when the card draws current.
