The power supply must be 350W or greater (with a minimum 12V current rating of 20A). One card which consumes less power is the Evga GeForce GT 430 requiring 300 Watt or greater with a minimum of 22 amps on the +12 volt rail. The lower memory capacity has less heat but less gaming satisfaction, and it's compatible with Windows 7.

If you're asking about phantom power, yes, it provides it. Maybe the question came because of the USB capabilities - just making sure you dont think it's USB powered - IT IS NOT. You need the included power supply at all times. A friend of mine made that mistake and was disappointed.

No, power is only needed when using items that exceed your computer's usb maximum millivolt output.

I do not see any indication that it does, it doesn't offer any power once unplugged and I cannot see any other reason for it.

Hi. With this device, you do not need any external power. The device brings it all included and takes what it needs directly from their computer. It works excellently. Regards. Vincent.

Not needed, but if you have a lot to go through it does help. Also, you may happen to have a number of these power adapters laying around, you might already have one that works. Check that before buying one.

Yes, it draws power from the computer via USB, and it receives the audio signal from the headphone jack. No additional power input is needed.

This has the power option...but is not needed. I have been using this for the past 3-6 months without additional power. Xbox/PlayStation/WD Box. For the $ I would purchase this many times over. If you need the power Radio Shack has them cheap.

No. It does not. The power supply is only via the USB connection and it draws its power from the PC/laptop it is connected to. With the price, I would expect a alternative direct power option.

Negative. Motherboard itself supplies the power, though I would recommend making sure it can provide the required 350W.

No, it powers up on it's own when connected to the USB cable that is provided with the package.

The answer is no. It does have 2 imputs. One for power. One for the audio that goes to the computer.

If you have it connected to a usb source like a PC..Yes it does, but I think only at whatever the source output is. It works much better with the 2.5 amp power supply attached.

Sorry, don't understand this question. Extra power supply to what? My review was about the battery charger and it doesn't come with a power supply. You provide the power supply by plugging it in to an electrical outlet.

Yes it does! You will be amazed hoe much power it has when putting a new battery in. I highly recommend it.

Yes it does because it is the only way it gets power. If you didn't, it would be like buying a scanner and not getting an AC adapter to make it turn on.
