how many watts does my power supply have to be

You're PSU must have 75 watts free to have this card run. Example, if your computer and its components run at 400 watts and you have a 500 watt PSU you could add this card and have 25 watts left over.

The power supply is 350 watts. You will need a different video card than is on the motherboard so add that cost.

Depends on the rest of your hardware. This card uses 150w, you will have to calculate the rest on your own. Minimum recommended is 500w.

No, I got a 550 watt power supply and it didn't work you need at least a 750 watt.

it's 65watts, so it all depends what else you are running. I'd suggest to use a power supply calculator online to figure it out.

You will need at least a 400w power supply. But it does depend on the other components in your computer. You can figure this out by adding up the power usage of all your components. You will want your power supply to provide more power than you need. You can search on line for power supply calculators. They will make determining your power supply needs a little easier.

depends on other hardware, graphics card, number of harddrives etc. google "psu calculator" and compute your power needs

300 watt with +12 at 18 amps is the minimum recommended for this video card

No. The motherboard and other devices will pull an average of 100 watts combined. You would need at least 450 watts.

I am using a 650wattt power supply. The card needs a power source other than the mainboard.

If you use a branded or certified power supply (i.e. thermaltake, antec, coolermaster, etc), 420W should be enough (at least 700W for a generic power supply). There are several power calculators in the web so you can be more specific (i.e. aditional fans, lights, drives). I made a calculation with a mid range processor (core i5) and 2 x GT630 (crossfire), and still did not need more than 420W. I hope that helps.

I suspect so but I am using a 430 watt PSU. Go to pcpartpicker.com and enter your components such as graphics card, motherboard and hard drive. Enter any component that consumes power. It will then indicate how many watts your system will use.

400 would be pushing it. I have a 600w and it does fine. I would say the minimum would be 500w but it really depends on your total power consumption system wide.

Your power supply is more than enough for this card. 300 watts is the minimum requirement, you have 350 watts so you are good to go, my friend.

That depends on the graphic card you will be using.650 WATT FOR SINGLE CARD. 2 GRAPHIC CARDS 750 WATT. I RUN A 850 WATT FOR MY RIG POWER TO UPGRADE.

As long as you have a pci express-16x slot it will fit and the power supply should be at least 500 watts

You will want a 500 watt power supply min if your running 1 card. I do not have a program to test the power consumption it dose take a single 6 pin.
