I'm thinking about adding more 2Pacs to my setup but I have a Superbpag hub and it's only rated to 14 Amps. I'm trying to figure out how much more juice I need to add more. Am I correct in assuming that the amount of draw I need per port is relative to the clock frequency the chip is running at? I've got the 2Pacs running at 275mhz so per the chart that means if I'm running 8 2pacs then I need 2.4amp draw per port (19.2 amp total) and 96 Watts of power?
Superpag=7 slots, although i was not able to run more than 5 Compacs on it (others may have run more).
NFW figured out that slots are grouped in 2-2-3 fashion, so that helps.
I tested running three: one in ea "slot" group. Maybe you can run two in the last group, so it would be four total (in positions 1,3,5,7). I very much doubt that you can run four at 275 (due to box overheating).
Actually, that ^^ is for Plugable's 7-port '60w' charging hub that I opened up. Not a Superpag hub.
That said, I would not be surprised to see a similar setup in other charging hubs not specifically made for powering stick miners. In short, open up the case and look how the USB slots are powered. Bet very few (if any) use a single regulator and like the ones from Plugable use multiple regulators with each feeding just a couple slots.
