I want to buy a GTX 650 2gb version

http://www.newegg.com/Product/Product.aspx?Item=N82E16814130831

Now my power supply is 300w. The card has a requirement of 400w.
My questions is can i upgrade my power supply? And if so, how and which one should i use.
Im on a budget so something cheaper would be nice. Also what are the risks of messing up the install and how hard is it.
*I have experiences with installing graphics cards, ram, and hardrives.

With a TDP of 65w that card should run fine on that box if the PSU can actually caugh up what it says it can.
Does the PSU have a label on it? If so, can you please take a picture and post it?
Does the PSU have any PCIe power cables?

The power supply looks like a standard ATX. I'd get a Corsair CX430. Not sure I'd trust the OEM unit.

Take Bobnova's advice and go with this one instead: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026&Tpk=cx430

do you guys think it will fit in my small case? i measured it with a ruler and got 5.5L,5.8W,3.5H roughly

Nothing like a bad PSU to kill your PC, i would listen to what these members are saying to you! I have seen all the power supply's and reviews Bob does, so he tells you something you better listen. AJ.

The basic TR2 series is absolute junk. The whole thing.
