Question RTX 4090 for 3D Rendering - Burning Connector Risk?

[jtyubv]

I was planning to get an RTX 4090 for 3D rendering animations (Redshift), but I'm concerned given there have been more reports of melting connectors. Considering the nature of 3D rendering, the card would be working 24/7 for days and sometimes even weeks at a time. I'm concerned with that much power running continually it would be more likely to melt the connector.

My plan was to power limit the card to a 60% power limit regardless because I've heard that results in the highest efficiency without a huge hit to performance, but I don't know if power limiting the card through software like MSI afterburner would reduce the risk of the connector melting, especially considering how long I would have the card rendering at any given time.

I feel like it might be safer to just get two 4080s instead since they seem much less likely to melt, although I'd definitely prefer the increased VRAM of the 4090. Any thoughts on the risk given I'll have these cards rendering nonstop for extended periods of time?

Do not think anything to worry about because there been comments saying that people are not plugging the wire correctly into gpu or bend wires. But if 4090 had melting issues then where is all the threads saying why my 4090 wire melted.

I have been running my RTX 4090 for the past month 24/7 for training deep learning models and nothing happened so far. I had the same worries at the start but I had to get the best GPU rather than thinking a small percentage that had problems. You can buy a cable from your PSU manufacturer that connects directly to your PSU than using the included adapter. Make sure you connect it correctly and you won't have any problem. For professional workloads as you already mentioned the 4090 is a better option cause higher VRAM/Memory Bus.
