Source? I don't see how the tiny traces leading to the M.2 socket can carry 3½ A
I found a picture of a sticker on its back side, it says 3.5A https://www.servethehome.com/crucial-t705-2tb-pcie-nvme-gen5-ssd-review-phison-micron/
Sheesh, you're right. I hope they mean the sum of currents over all 9 power pins like u/kaszak696 suggested
Currents in parallel branches of a circuit add, so that's likely the case
