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.
Tell me about it... this isn't exactly one of my favourite videos either, 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.
@@Adamant_IT you also should never reuse a bad cable(i understand it may still work fine but with out replacing the pins you will never know for sure), especially one that has doubled ends on it like this one does. that gpu should have 2 dedicated cabled from the psu to it.
FYI - So RU-vid 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.
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.
Coincidentally, I did my first PC build about two weeks ago, with exactly that Corsair case and PSU. I commited no rookie mistakes because of this channel, my main source of research to finally got where I am today, typing from my new PC. Thanks Graham!
God damn, I kept thinking "hey this bloke looks really familiar" then realised you used to go into Netplay when my daughter Siana was working there :) I'm the nutter bloke with the three wheel van and still often messing around with PC's. I seem to remember you being out with Tom and his brothers one night and we had a right ol' chat about PC's.
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.
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.
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.
I used to work for the Service Dept at Fry's Electronics (till they went out of business). A lot of the troubleshooting techniques you displayed here are excellent! I am very impressed. A great show of skill and experience!
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.
imagine being recommended this video and not finding it on your own by searchin' up computer fixing stuff. Nice channel, my dude! Informative so far, and will definitely be helpful.
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.
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
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.
@RJ Games Productions Quarterbacks cannot function unless the team of arm-chair quarterbacks tell him what to do after the fact when it can do no good.
... 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.
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.
I'm binging your old videos and it's been very interesting. You provide great service and I wish I had someone like you here locally. Greetings from the U.S.
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.
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 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
I use optical drives all the time. And most of the usb drives don’t last. I will always use a case with a bay even if I didn’t use it all the time. More convenient that way
On my last build It was 3 years before I ever needed to use the DVD drive. thought it was dead when I finally needed to use it. Turned out I never actually connected it when I built the system, lol.
it seems odd how much space cases have in the region that was normally used for that. Steps backwards. Getting rid of the mounting options should mean getting rid of the dead space
Discovered this as RU-vid subscribed, it's unfortunate that that small error of not making sure everything is fully pushed in. But any first time builder can't make mistakes I did with my very first ever Athlon Barton 2500+ back in 2000. 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'm tempted to do a RGB build, never did one before. I was able to spot that before you zoomed in. I always connect the cables to the power supply before putting it in the case.
And here I thought I know hardware... Well not as well as a guy that could pass for an electrical engineer. I'm super surprised that card still worked. And that the PSU didn't get damaged. Wow. A testament to why you buy good quality parts while some POS PSU can just blow out even with normal use that Corsair took a beating and still works fine once you cleaned up the arc. Pretty amazing. Great vid.
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
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.
I do love my customer built pc repairs, very interesting to see how different folks think when building these computers. Sadly I have seen my share of pcs brought in that were completely nuked (Fried) from poor connection arcing or extra standoffs left behind the MB during their install. I've seen a lot in my repair years, some funny others, not so much ;)
I had a Seasonic PSU cook the end of a pcie plug once, I think it had to of been the pins in the plug wasn't crimped on the wire in my case, I put a new end on the wire and salvaged 8 pin EVGA modular port off a junk PSU that fit perfect, just had to get the right pinout, Its still working 4 years later powering a 9700k and gtx1660.
To be fair my case I recently built in, a Phanteks p500a doesn’t have an HDD led. I miss it, as it’s a feature that I’ve remembered for 20+ years but I haven’t necessarily needed it
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.
I really like the case, being someone who's never had any major problems with them, and their updated iCUE is a lot less of a hog than it used to be. I actually had a laptop that iCUE would just crash after like a second of appearing until the redesign
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.
Praise the Algorithmic Gods. didn't even tell me why it recommended your channel but i see a Tokyo Ghoul Unravel video in the suggested after this.. you know i'm watching that %.% yuss
First thing i saw here is actually the extension cables. I never really liked using mod cable at all if its just for aesthetics. I rather have it directly connected instead of extension even if its a non-braided ketchup and mustard case
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.
@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.
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.
@@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.
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.
nice vid my friend! how many times I've got rekt cuz of these errors from first time rookies! :D this was a good one to point out the most common errors! :) btw the system instability post messege is 99% power deliveri issue error! ;) keep up! :) WoW :O thy God I have a 980Ti! :'D scores 19557pts. (Gigabyte Extreme gaming)
I worked in a computer store many years ago and have seen a couple of not-so-great customer builds. One in particular, they didn't use the MB spaces, so they screwed the MB directly to the case. Nothing shorted though iirc
I had to check my new pc build powersupply connections, that it was connected properly. And yes it was done properly. So I quess always check you build for build mistakes!
I’m currently using this case and for some reason fresh out of the box, the cut out for the IO part of the mother board of the case is bent so i had to just go with it
when i saw the size of your coffee i was like dude what time it should be? then you said it was 2 am and i was like how this guy could sleep after that 500ml of coffee hahahahah. btw i love your videos, i am always watching
Yea, I agree, don't think we need HDD LEDs any more. Mine is now my power LED as the blue one on my Zalman S2 case died, so I moved the HDD LED leads to the power indicator posts. The only need for a Reset button these days if for an RGB hub, LOL.
I think it would be a good solution to stick an LED on a 5V or 3V3 rail. Still, some laptops only power (don't know really for newer ones) USB when the laptop is powered ON. So, an USB device with an LED would be useful in that case.
I take it the plug was like you say either arcing or it was that the other pins wern't connected in and that resulted in tons of current going through a single pin and therefore lots of heat. although the arching would explain why the LED's/power was flicking like mad due to voltage spikes.
This exact same thing happened on my first build. The thing booted up and everything worked fine, though I could smell a slight burnt plastic scent at all times, I checked everything inside but nothing was burnt or melted so I figured it was just how computers smell. I didn't really know about any of these things cause it was my first time owning a computer that wasn't a laptop. Turns out the power cord that goes onto the power supply was not plugged in correctly and it was fried to a crisp, dunno how my computer managed to work like that without issues for 18 months.
Just for anyone whos wondering this is my PC and i brought it in to Graham. It is my first time build and know i made mistakes. The cable into the PSU seemed like it had clipped in but after having problems i knew it needed to be fixed by a professional.
