Yeah you definitely won't get away with a somewhat decent voltage drop, especially if you were to load it down with 60a. Since much of our stuff is ultimately stepped down to 5v it doesn't really have too great of an impact.

These boards are made with 2oz copper to better handle this capacity. I see some boards out there miners have been using that I'm sure are 1oz and some are throwing the 1200w supplies on them and that scares me some with a 24/7 load lol. Was gonna do a 4 layer board but that would have added significant cost to them.
