Question 1

What size power supply does this card require?

Accepted Answer

I can't speak to what is REQUIRED, but I am using it with a 450W supply and have no problems. It requires 1 PCIe 6-pin connector.

Question 2

Can this run on a 300wattage computer?

Accepted Answer

I'm assuming the question you are asking really is, "Is my 300 watt power supply capable of running this card?"

The answer is 'maybe'.  If your computer is a typical  (any store-bought system, for example) and you are not overclocking it, 300 watts will be just enough.  My q9450 computer with a GTX650 runs at 120 watts with no load and 195 at full load.  You should be fine.

BUT!!!!  Make sure your power supply has the 4 pin connector (or 6 or  pin, but this thing just needs 4 pins) that is designed to give PCI-e cards more power.  Otherwise it will only run at half speed until you spend the $25 to upgrade your power supply.

Good luck!

Question 3

Will this fit in a mid size tower?

Accepted Answer

It is a tight squeeze, and you may want to go with a full size, but yes it will fit.  Getting a mid size tower with room behind the motherboard for running cables goes a long way to making your GPU fit nicely.  Also it will look better.

Question 4

Is this compatible with a PCI-e x16 1.0 motherboard? My motherboard is an MSI G31M3 V2.

Accepted Answer

Yes. I'm using it on Asus A8N32-SLI (not in SLI mode though).

Question 5

What is the minimum power supply requirements?

Accepted Answer

I have been using it for well over a year now with a 450W PS with no hassles of any sort.
