Hi all, I had my 4090 installed with a CableMod 90 degree adapter now for around 4 to 5 months with zero issues.
However yesterday I started having random black screens in gaming and even just browsing the Web. Tried updating drivers etc to no effect, finally thought I'd reseat GPU cables and found that the 90 degree adapter had melted slightly at the bottom and completely fused itself to the GPU power connector.
Now I'm unable to remove the adapter and obviously the GPU is pretty much bricked.

Anyone have similar issues, contacted both Asus and CableMod support so hopefully can get this sorted under warranty.

Wish me luck
 
Oh dear, really bad there and I hope you have good fortune with any warranty. I hope I am wrong but I suspect neither Asus or CableMod will sort under warranty. Asus because you used a 3rd party mod and CableMod because well they don't make GPUs and might just say, here's a replacement connector.

I have a 4080 for about 8 months and over the past few days I had random black screens and at one point my very expensive HDR 4K monitor was giving just washed out grey screens. I tried a new DP cable with no fix and after some reboots the monitor "sorted itself". Though I was still getting a random failure to boot with a GPU error light on the motherboard. Then I remembered the really poor power connector design and I reconnected my standard Nvidia supplied connector, all issues are resolved.

Wow, I thought this only affected a small percentage of people and really sad this it has happened to you. Hopefully you get it sorted via warranty.

Also haven't Nvidia fixes or updated the power connector on the GPU?

From what I have read CableMod have bben taking care of people with this issue. Contect them.

I read they'd stopped replacing GPU's due to the cost, but yeh, contact them to find out.
 
Thanks for the replies guys, have contacted both Asus and CableMod support, just a waiting game now. Not helped by the fact its a bank holiday weekend, hopefully won't be without a GPU too long

Worst I have heard is CableMod paying for cards to be repaired.

I normally wouldn't feel confident in such a complex device getting repaired by someone other than the manufacturer, but the connectors themselves are simple components. A competent repair shop should have no problem replacing it.

Yeh, hope they get sorted, I'd be crying if it was me.

I can't believe that this is even an issue on a card that costs £1600 - what exactly did they skimp on?

Seems like the 12vhpwr connector is just poor design, I'm willing to bet that the 50 series is using an entirely different connector. While the 4090 performance was great once I get it sorted with either refund or replacement I'm seriously considering selling it on and just buying a 7900XTX instead

Nvidia definitely won't be making the same mistake again with the 50 series. Will they lol?

I think the connectors that have the problem are because the pins are too small or they use fused pins so you end up with to much current across a small subsection of the contractor, which in turn causes heat to build up.

Is the power connector on the 4090 different vs the 3090 because I haven't read of any reports of connector failing on the 3090?
 
MadMossy said:
No idea, does the 3090 use as much power as a 4090 even?

Yeah it's a different connector, has sense pins across the bottom which are apparently the cause of a lot of these issues.
Had a 3090 previously with zero issues, the connector always felt solid on that card. Even when fully plugged in the 4090 connector feels wobbly, such a poor design for a £1500 GPU

You would have thought that their flagship GPU would have gone through vigorous tests before passing Q & A and selling it to the public...
