Info 12VHPWR PSA on cable bending

[n0x1ous]

The most recent theory is that its the connector not being fully seated into the port on the card. I can confirm that this connector is the hardest PSU cable I have ever seated before. I don't think its a stretch to say that less experienced builders might think the cable is fully plugged in when in reality it isn't. I had to hold the back of my case with one hand and push with nearly all my strength to get the audible click when inserting the plug. The plug heats up to insane temps quickly when not fully seated according to some recent reports. I am using a cablemod 4x8 pin to 12vhpwr cable. Never tried the Nvidia adapter. Checked my cable a couple times for melting and so far so good.

I'm using the native 12vhpwr cable from the MSI mpg a1000g PSU. It wasn't hard to plug in at all but I also had the case down on a hard surface and then pressed the connector down into the card as hard as I could. The card moved a bit but that's fine it was already in the slot.

It made an audible sound but not a super loud click. I'll keep checking it on a weekly basis too.

If i understood correctly, these cables have a "life cycle" of 30 connects / disconnects meaning, if you check once every week, in around 7 months the cable will have to be swapped ...

I heard that too but other than checking a few times I suppose you are supposed to guess it's ok? Otherwise I would need to ask MSI to send me a new cord in 7 months. Which means everyone would have to get the respective cable from their PSU manufacturer.

-But everytime you unplug it, check, and plug it back in... you could have plugged it in wrong so you'll need to unplug it, check, and plug it back in but then you might have plugged it in wrong so you'll have to...

Just leave it plugged in. You'll be fine as long as you didn't put the connector under any kind of horizontal or vertical stress. I'm very happy with my ATX 3.0 Thermaltake PSU.

Did you ever get gigabyte control center to work? No clue how I can manage the card and led stuff if their software doesn't work. I downloaded the control center from their website and the app opens up to a blank screen.

I never could get it to work right. I tried to adjust the RGB and it never changed. I deleted the software and don't worry about it.

Hopefully when Nvidia releases the 4090 Ti, they'll switch to the incoming 12V Extra High Power Cable. Having the connector soldered onto the card with a pigtail should help with bend radius and cable management too.

Figures..this reminds me why I was always skeptical with gigabyte. They have improved from the past in terms of hardware but their software is almost non existent. It's like they didn't update the software before launch at all. I'm using evga precision X1 to look at the temp and memory/GPU clock speeds. I don't need to OC the card at all.

It would be nice to set a custom fan curve like I had for my 3080Ti but none of the other software can read the fans.

I wonder if software like SignalRGB will ever be updated to work with it?

That's the small version, right?

Annoyingly after this became the accepted conclusion it seems jonnyguru deleted his entire writeup where he went all in on blaming fully seating issues. Surely someone here is in his discord and/or has heard why he deleted it.

The more I think about his and gamernexus's testing where they literally snipped multiple power pins and couldn't get a failure the more I think about how something completely different is going on here. I guess if loose connectors cause all but one or two pins to seat then maybe that can cause a melt but then again neither of them could actually replicate the problem in any way shape or form.

I would assume that if I started snipping wires off a normal 8 pin I could get it to burn up. I'd really like to see a lot more testing and IMO the current amount of testing currently shown to the public is very weak. For instance nobody ive seen doing testing on the dongle has actually even bothered to try measuring power consumption while stress testing it.

My only conclusion with their testing method is they used FE 4090's so there must be something different with the adapters of the FE series or the cards themselves.

All the adapter cables that melted and the 2 native 12vhpower cables that melted were from AIB partners and Nvidia contracted a third party to make those adapters for the AIB cards.

I'm using the pcie 5 MSI PSU with my 4090 and have been gaming on it for the past week. I did pull out the native 12vhpwr cable to check and luckily it still looks like it did when I first got it.

What AIB is the best with warranty coverage these days? I was thinking of getting a card on stockx (there is a markup but it's less than ebay or other sites), but am concerned about them denying the warranty if there are issues with the connector melting. EVGA used to have the best support but they are not an option anymore. I don't have the patience to sit through those stock trackers and alert bots at this point.

I can't say anything good about gigabyte support. I tried to download gigabyte control center to change my 4090's fan curve but the damn software opens to a blank page.

Sent a support ticket to gigabyte but never heard back. I found Auros engine which can read my card so I can do that there.

I would probably go with Asus or an FE if you can get one. I bought extra warranty from microcenter so I wouldn't have to deal with gigabyte in the next two years. Even though Gigabyte says the warranty is for 4 years.

I've had to RMA a GB 1070 a few years ago and the card had like two weeks left on the warranty. GB repaired the card for free no questions asked and sent it back to me quickly.

 

[CP5670]

I was thinking of the FE or MSI Trio. There have been reports of bad support from Asus here. These cards usually have 3 year warranties, but it's common for companies to deny them if you didn't buy from an authorized reseller. I do buy used cards and am comfortable with that, but in this case the melting issue seems common.

You can use MSI Afterburner to set the fan profile, I don't bother with the other AIB's apps. The only thing they are good for is setting the RGB, which doesn't even work half the time.

 

[sze5003]

I didn't realize MSI afterburner can read the fans of the gigabyte card. I'll give it a go and I also noticed at least rgb fusion 2.0 works for the gigabyte card to set and save the rgb.

I'm gonna try out open rgb to see if it will read the card, board and gskill ram. I hate having armory crate from Asus installed for the motherboard rgb stuff, another rgb app for the card, and yet another app for the ram lol.

One thing that I realized is gigabyte has their bios for the 4090 oc mixed up. The instructions say to run one executable for the switch in OC mode yet when you run that file you get a prompt saying the bios does not match.

So you're actually supposed to flash the executable that's in the instructions for the switch in silent mode.

Yep, same thing with "is my CPU cooler mounted correctly, let me check the paste spread underneath..."

My only conclusion with their testing method is they used FE 4090's so there must be something different with the adapters of the FE series or the cards themselves.

I think it's the 4090s themselves. That explains why reviewers abused the crap out of the cables but couldn't cause the issue, because each only tested a single 4090. But the internet has a sample size of many 4090s.

NVidia digging deeper

 

[Carfax83]

I've had my Zotac RTX 4090 Amp Extreme Airo since Wednesday and I've honestly been trying my darndest to get the cable to melt by playing long gaming sessions at 4K with all settings maxed including RT on in several titles. I bought it off of Amazon so I have until January 31st 2023 to send it back for any reason and get a refund and I'd rather it fail early than 6 months down the road and have to deal with the RMA process.

So far everything is good though. Card runs cool and pretty much never exceeds 65c, even at close to 2.8ghz. I'm not even going to bother overclocking it in any way. A guy on r/nvidia with the same card as me recently got one of the outer pins in his adapter fried while playing CB2077. I think he said he had just owned it for 4 days. So far I've had mine installed for the exact amount of time as he.

Lets hope that if mine does fail, it fails sooner than later My instinct tells me there is a QA failure with certain adapters not being standardized properly by the manufacturer(s). That's the only explanation that makes sense as its only affecting a small percentage of card owners who purchased from different IHVs that are likely all buying some of these adapters from the same companies.

First confirmed case of Founders Edition melting:

Still not a peep out of nVidia. Recall or class action lawsuit, wonder which'll come first?

 

[sze5003]

If they do a recall I wonder if AIB's will also fall under that category but it will be up to the respective companies to follow through with it.

I'm pretty sure they don't know the cause or solution at this point. Which is concerning although it's still a small percentage of cards that have melted. Maybe like 25+ out of the thousands that are out there.
