6800XT connected to PSU via single cable
I saw this picture while looking at overclocking guides and I wondered if I may have my power setup incorrectly. My GPU is currently connected exactly like the don't do this diagram.

Is this a thing with new GPUs? I've always connected my GPUs with 1 cable there was no option for 2. I currently have a RX5700 XT.
I am using a RX 6700 XT on one cable as well and it's perfectly fine. If your PSU has a second cable you can run that to be sure, but if not like mine don't worry about it. It's only certain corner cases like extreme overclocking, or certain cards and PSUs that violate the specifications that actually cause issues. The Radeon R9 295X2 would be an example of this. 12VHPWR actually runs a similar amount of current per wire, with an even smaller connector, as a daisy chained 8 pin setup. You should not use third party splitters though if you want to be safe.
I changed it when it kept crashing on me. Then I bought a new power supply and the crashing stopped. That's what I get for ordering the 7/7/7nm/'700xt from XFX...
Edit: they should be on separate rails, so it's not a bad idea, especially if you're having stability issues.
I have a 7900 XTX, having upgraded from a 5700 XT, yeah it's a thing, and it is also a much chonkier boi. Weighs like 2.5 kilos, barely fits my case.
I knew GPUs had gotten bigger but then I built an all new PC, upgrading from a 2080 to a 4090.
Holy shit. That thing is fucking huge, man. I was literally stunned pulling it out of the box. Just set it down and stared at it for awhile trying to process technological progress. It's like 8 times the size of the GPU I had in 2006.
The volume of the PCB should be the same in both GPUs, the difference is that the 4090 has an enormous cooler/heat dissipation.
I installed another fan into my case just so that monster is not resting solely on the back mount and the PCIE port.
As I type this I"m in the process of building a new computer, going from a GTX-1080 to an RX7900GRE, and it's relatively small, I got a 2-fan Asrock Challenger one and while it's bigger than the 1080 it's not as big as some I've handled. It's amazing how they managed to pack the 1080 into such a small package. I guess the blower fan helps.
