Okay so from what your power supply states you have 384 watts of power you can use on your graphic cards. Now here is the issue I have with the unit they gave you is that its not a single rail line its a two way split. However needless to say I'll find something real fast.

Okay so I went through a nvidia list with your power supply you have you could use a 680 granted you had the cables to power the device. And you have to have pci-e connections I'd think with 2x 12v rail lines like that. I also went through AMD list but they was unable to find there max operating power requirements.

Nvidia does a real good job at listing them out I'll give you the link. (Max graphic power)...

Just some quick advice, it's usually a good idea when asking GPU questions to say what you need the computer for, so what games or other applications, what resolution, multi monitor etc.

Regarding the PSU, I believe there are AMD HD 7750 cards that don't require the 6 pin connector. I don't think you can get much faster. Is it a proprietary case? You could replace the PSU if not. Of course it all depends on your graphics needs.

Hope that helps

Now I would recommend since it sounds like you have a no name PSU anyway that you go out and purchase a power supply that not only has sufficient power but the outputs you need for a graphics card seeing as you say you have no 6 pin or 6+2 pin pci e connections something like this for example.

i need this computer for gaming, games such as skyrim, far cry etc on high settings. my monitor res is 1366x768. ive found a adaptor that changes the molex pins on a chain to a 6 pin so im wondering if i could do that, i'm not to keen on changing the psu, i just kind of want to know if the psu can handle a high end card.

thanks for the reply!

You could. Typically you need 2x 4 pin molex connections to 1 PCI-Express connection. I don't recommend doing it because you should have a proper quality Power Supply however that is your choice.

Also keep in mind the resolution you are running at is very low in comparison to what others are running now something like a GTX660 is as far as I would go or a 7850 for that. Nothing further sir not unless you run out and get a 1080p screen and run it at that resolution or higher.
