What the money in our pocket allows us to afford is not the same as what our health and planet can afford.
Causing that disconnect by supplanting secular consideration with economic consideration is one the reasons so much evil is done and accepted in the name of profit.
Yes.
And yes. The cables don’t come with the GPU. 5$ more for every new PSU made is not a drop in the bucket.
And I don’t think you realize how thick, cumbersome, and stiff, two sole conductors that can do 500W at 12V would be.
The only reason mains power cables are so thin, is because they operate at 120-240V, allowing the amps (and the stress on the cable) to be fairly low. (It being AC also helps, the problem is WORSE with DC)
To do 500W at 12V, you need truly massive cables. And it gets exponentially bigger the more these cards pull.
In fact, the XT60 would not be enough. It can handle bursts of the 700 watts a 5090 can pull, but to deal with the fact that these GPUs pull that continuously, you need to go all the way up to an XT120.
