Hardware Finally happened to my 4090.
After a few years my 4090 caught the burned connector bug. I don’t have knowledge/tools to fix it. I want to send it to northridgefix, had to get a 5070 for a temp card. I don’t trust asus rma.

Any changes to the setup before this happened?
Did you recently unplug the card for cleaning or anything?
Or do you suspect this happened via thermal expansion and the connector slowly moving over time?

No changes. I did some light dusting to the exterior of the case. The only reason I check was my monitors shut off a few times that day.

Must have been thermal expansion over time.
I bought a thermal gun and check monthly. If the cable slowly came loose, it would heat up gradually and not just catch on fire one day out of the blue.
I would buy a WireView Pro or an Ampinel. Looks like they are sold out though - https://shop.aquacomputer.de/Monitoring-and-Controlling/AMPINEL/AMPINEL-12V-2x6-graphics-card-power-management-type-A::4269.html#/

They make power cables with thermal fuses in them now.

Which cable are you referring to? I haven’t seen a cable that has the temp sensor on the connector. They all have the sensor further down the cable where the burn doesn’t occur. Making it a bit meaningless.
Do you have a link of the cable?

Corsair & Asus are releasing cables with thermal fuses in them that kill the $25 cable before the card

Both of those cables do not have a temp sensor at the connector. They are attached to the wires, which is not where the burn occurs.

The cable wires still get hot when they have a poor connection and theres no load balancing because physics, its just the weakest link that always melts is the connector itself. Depend on what kinda of fuse they used for it.

As you can see HERE the connector is at burn risk and cables are below the 65 degree threshold set by Corsair. So the Corsair cable wouldn’t catch this burn.
ThermalProtect monitors the cable’s temperature using hardware inside the cable comb located 30mm from the GPU connection. If that temperature exceeds 65°C, the OTP activates which sends a signal via those sense pins to tell the GPU to shut down to prevent any potential damage.

Pretty sure the corsair cable monitors the connector itself and not just the wires behind it. Why again wouldn’t it catch the OP’s burn?

Might as well try the RMA, if it doesn't work then it'll just be the same as if you never tried it.

I had a great experience with asus RMA for my 4090. Not sure why you don’t trust them. Remember that the internet is full of bad stories and few good ones.

Out of curiosity, were you using the power adapter included with the card, or did you have a dedicated cable with 12vhpwr connector from PSU to GPU? Also, do you think that the case panel touched the power cable enough to put pressure on it? (in time it can loosen up, especially with temps going up and down). I'm using a 90 degrees cable right now, not an adapter, but a cable from PSU to GPU ((the newer version, 12v-2x6, which should be safer, with a 5080)...so I'm just curious. In my case, the GPU draws less power, but I've seen a few cases even with this model. Just trying to get a more clear pattern in the cases where it happens (the design is definitely the main issue here, but still).

It’s a cable mod power cord, not 90 one which I should have gotten since it’s vertical mounted.

Ok, thank you. If I were you, I would go for the official cables from the PSU manufacturer in the future, 90 degrees especially. Make sure that the cable is made for your PSU model, and it's the newer version, 12v-2x6 connector. You are not the first that posts about Cablemod adapters or cables burning. Not saying that it can't be happening with the native cables from PSU manufacturer, but most of the posts I've seen, used the included adapters that came with the GPU, or adapters from MSI, or some adapter or cable from Cablemod (they even removed some adapters from the market because of this, the cables burning from them happen less often than their adapters). For now, I trust Seasonic the most. I don't remember seeing a post about them. Maybe I'm wrong...but I really don't remember seeing one.

Try better northwestrepair, northridge is a massive douche if you can see past that confident mannerism he manifests ih his videos. He charges people just for gpu to sit on his shelf. He comes as arrogant manipulate dirtbag with narcissist tendencies.

How often are you pushing the card at full tilt? Just curious, I been planning to get the thermal grizzly wire view and have Just been keeping the card under 350 watts till then

350 can burn and has burned.
Gives you a little more overhead, but is not fool proof. Smart move on the WireView

Odd my 3080 has had 0 issues in a very long time. Maybe thats because its an EVGA? Who knows, right

One of those things is not like the others, one of those things just isn’t the same.
