are all 12 ports powered?

Yes, all 12 ports are powered with the same voltage. The current is shared as needed - the sum of the current for each device ( watts / volts) must be less that 2.5 amps or 120 watts - each device takes the power (Watts) it needs from the common 48v source.

Enough to power the *entire* load your motherboard presents, plus a safety factor for inefficiency plus startup. It does not regulate the 12V, so no. Use a reputable 12VDC power supply, not one of those $8 specials. When I use these, I build the entire system and power it from an ordinary high-efficiency PSU, run at full load. Measure the power draw with a Kill-A-Watt. Size the 12VDC supply accordingly.

Yes. We have installed 12 on various machines here. Some were hard wired, and others we simply added a male plug.

NO! It is a powered hub. Having said that, I love these puppies. I've got 5 total in use and highly recommend them. (See my earlier review.) on USB 3 items, they'll draw power from their own power supplies and the computer itself, you DON'T ever want to take a chance of burning out the USB on your puter or the device (Like hard-drives) due to a low power situation, EVER!The plugable 7 port hub is lighted to let you know when the device is properly connected and powered, on each port.

Yes this is correct. Be careful to stay under the wattage I used two on mine to run all the things that I needed. You can use as many as needed to run everything.

It has 12 ports, 2 switches ( each switch controls 6 ports)And i agree it was a waste of money. It wont even power half my devices that i bought it for.

I am not sure if there are power limitations, but you technically could plug them all into here. I use every outlet, but all of the equipment is not on at the same time.

The answer is yes; 4 different peripherals can be connected to be powered from 1 usb hub of a pc. With multi connections case; in order not to lose any data transfer speeds of the connected devices, usb hubs of the pc should either be usb2.0 high-speed type or -much better- usb3.0.

I will have to check. Only one end needs to be powered. We were using them for sending POS DATA back to a pc, ended up pulling them out and installing a serial over cat5 instead to clear up some intermittent issues we were having. You may not have any trouble with them we had kind of a special setup I think is why we had issues.

No, power supplies are separate. It is PoE though if you have a PoE switch.

Yes, the ports are labelled. There are notes on it too, saying the amps for each port.

All 3 outputs are connected to a single source. It does not matter which one you use, full output power is available at all 3.

You need to use a power adapter. Several of the ports no longer function (side note).

I can't remember exactly because I repaired the computer for someone else and I don't have the old parts to check. I think it is 12 pins.

In theory, yes, but don't expect to actually use all 7 ports at once. Only the back three USB ports seem to provide the amount of power needed for most devices.

As many as you want given your power supply can supply the power. I have wired over 10 together with no problem in referents and such

Yes, it can powered all the drives at same time. But this can't use as network media server.
