SABRENT7 Port USB 3.0 HUB + 2 Charging Ports with 12V/4A Power Adapter [Black] (HB-U930)

Q: what's the different between the one with the external power adapter and the one without?

With my USB 3 Ports on my Acer TC-780 front panel ports, I can power all four ports with thumb drives. When I tried the same with a Dell U473D Slim Multimedia Keyboard with 2 USB Port I had to use the pawer supply that came with the HB-UMP3 4-port Powered USB hub. I would advise getting the powered hub because you don't know if your USB port will support enough devices without the power supply unit.

Q: How many ports can I have active at one time, without overloading the single port of the computer?

actually, while you can theoretically link 127 devices, there is a limitation to the depth or hiearchy you can link hubs (which is 7). In many systems (particularly windows) you may find that the hub controller in the pc can consumer 2 or 3 of those tiers. While that's likely not an issue for most, I've run into a problem when I link a 7 port hub into a KVM switch -- I get an error message stating that the system can not see some devices (because the actual 7 port hub actually contains 2 usb controllers and the kvm switch contains 2 controllers). Suffice it to say -- this is a rare occurrence -- just don't daisy chain a bunch of 4 port hubs together if you run out of ports -- get a hub with more ports

Q: How long is USB3 cable?

measured mine at about 1 meter. I really like this thing. The two red high-power only ports are oriented 180 degrees from the USB 3.0 ports so you physically can't mix them up either.

Q: Will using a 7 usb 3.0 hub ultimately put next to no strain on my motherboard because power is being generated from the AC adapter?

I 5 Gigabyte Motherboard with powerful Intel processor, 16 Ram has moor paver than standard PC. I don't think the hub would help. However, some software might. I will look this up in the later date.
