NO and NO. Did not come with my unit from Fry's. Works without one but takes a while to switch sometimes. Goint to try it with one.

Yes - comes with the unit. As I understand it, HDMI switches need to be powered for good transmission of data.

Does not need external power supply BUT if your HDMI cords are the longer variety it will definitely need externaml power.

It just need to be plugged into the USB port of your computer. You will need a fairly good PSU otherwise it will be unstable.

No. Any standard atx power supply will work. Rosewill makes decent power supplies, but any will work.

The required power supply for this type of card is minimum 800w (espesially if you plan to overclock) with 2power cables dedicated for this video card, so make sure the number of power outlets from the supply is enough for all you other components (ie DVD drive, hard drive, ect) good luck

The power supply could be upgraded to after market atx psu with this adapter. http://www.amazon.com/gp/aag/main/ref=olp_merch_name_1?ie=UTF8&asin;=B00WE5KSFQ&isAmazonFulfilled;=1&seller;=A3FT23Z5YFYFF1or fromhttp://www.ebay.com/usr/donjonmin

Its a 500 watt power supply you could probably google it. It shouldnt have much effect espically if you are already running a desktop.

All you need is a quality 400 watt. Make sure its a good brand like Antec or Corsair.

There are several available here on Amazon. Do a search for "12v 4a power supply".

Any 12V power supply will do, Amazon has great prices on them; I wire these in "loop" fashion for equal brightness along the run and recommend 12 ga wire, also at a great price on Amazon.

12v DC Power Supply is needed. This should work fine. 1 X 12V 500mA Power Supply

any atx power supply with 24 pin and p4 cables will work. If they don't come with sata connectors you can buy a 4 pin molex to sata adapter. I buy Powork power supplies. They are inexpensive and I've never had a problem with them.

I use a old power supply from a xbox. You could use a pc power supply. you need some small house fans also.

You can use the 8 pin power cable if you have it available the one provided is just an adapter if your power supply doesn't have 8 pin connectors.

Any standard power supply will fit. You will need to determine your overall system requirements before you decide what wattage you will need.
