Also, like, I kind of want to play with these things, but also I'm not sure I want a computer that uses 500W+ in my house, let alone just a GPU.
I might actually be happy to buy one of these things, at the inflated price, and run it at half voltage or something... but I can't tell if that is going to fix these concerns or they're just bad cards.
With 5080 using 300W, talking about 500W is a bit of an exaggeration, isn't it?
It's not the voltage, it's the current you'd want to halve. The wire gauge required to carry power is dependent on the current load. It's why when i first saw these new connectors and the loads they were being tasked with it was a wtf moment for me. Better to just avoid them in the first place though.
