Since my computer is out of warranty, Acer will not answer my question. I hope somebody here knows.

I have multiple portable drives (6) that I usually have all plugged into the computer at the same time. There has been concern over the usb ports being able to provide enough power to that many drives. The question I'm being asked is "What does the motherboard maker claim about support of this many USB drives?"
I don't know much about computers and am being prodded by someone to ask. I have used Speccy to get some details but I don't know if the answer to the question is in there. I've pasted them down below. 
Would anyone here know the answer?

Thanks.

    The TC-710 meets spec for power output on each of the USB ports. That gives you 500mA on the USB 2.0 ports and 900mA on USB 3.0 ports. I don't believe you have any 3.1 gen 1 or 3.1 gen 2 ports which have higher budgets.
    Often you can actually pull more than spec, and a lot of older external drives take advantage and exceed spec, but you should just plan on spec and no more. If you have a device that pulls more put it on a powered hub.
