This is an awesome comment, thank you! I had long wondered myself why GPU power delivery was so complicated.

- uncledave 6y agoFigures you have to look at to be scared about in this space is an RTX 3070 can pull 250 watts and the core is 1.2v (I haven’t confirmed this) then the card can be sucking up an average of 200 amps. Which is a lot. Peak currents can be a lot more than that too.
- therein 6y agoThat's a crazy amount of current to pull. I have melted wires or even welded things together with a super-capacitor setup delivering a similar amount.
- rjbwork 6y agoMy 3090 tops out at 400W on a not even very aggressive overclock. And it makes my room HOT when it's pegged. These graphics chips are insanely power hungry and beefy as hell these days.
