I googled it and found this turbolink switching power supply model: ATX-TL500W-BK 12v
I'm sure you can have it.
I had a GTX 460 SE with 500 watts.
And GTX 460 SE uses more power.
So I'm sure you can.
Now, when you open the graphics card box.
There should be 4 pin molex to 6 pin PCie power cables.
You might have to take out some stuff like your CD drive or something to power it.
I never really used my CD drive so I took it out to power it.
If you already have the PCie cables there, then don't worry about what I just said.
Just plug the PCie cables, they're black and yeah, into the graphics card.
And insert the card into your motherboard.
Ok. lol. I'm very new to this computer stuff, never switched cards before. I'll try to find a simple guide on youtube. Hopefully I don't mess this card up while switching it, last one I messed up trying to overclock it, but I'm not overclocking this one
