Nvidia power meltdowns hit 8-pin adaptors — old power supplies are the common factor

What do you expect from running 10 and more amperes through a cord?

Well , I expect enough engineering behind it that the cord and connections don't melt. I am an auto electrician, I routinely deal with 12v systems that draw much more than that without melting, using connections that aren't much bigger. It's not like it's some mystical technology, it's just that this setup has been done on a budget.

But it doesn't help that every single logic gate in a graphics card is run at a speed/currents that are literally just below meltdown.
