I was just wondering how I can tell what power supply is compatible with my motherboard? I am considering on going to bestbuy and buying a better power supply for the use of a graphics card

my new computer is a Gateway - Desktop / Intel® Core™ i3 Processor / 8GB Memory / 1TB Hard Drive
Model: DX4840-03E | SKU: 9973838
and I have an XFX PVT98GYAF3 GeForce 9800 GT 512MB 256-bit DDR3 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
so i don't know what to get on terms of a power supply, and what is compatible with my computer. I live close enough to the Bestbuy in Moline, Illinois. So I want to get one instore not order one online

Also the power supply I'm looking at is a 

Corsair - 650W ATX CPU Power Supply  Model: CMPSU650TX | SKU: 9358269 is that compatible with that computer?

The 9800 is neither a powerful nor a power-hungry card. It should work fine with your motherboard.

I am willing to bet that the current PSU in your computer would support the GPU you are wanting to install on the computer. That GPU is not as power-hungry as a top-end card, so won't utilize too much power.

I honestly would recommend installing the GPU first prior to spending money on a PSU you may not need. If the computer seems to not be working, you should be able to install the corsair 650w PSU into your computer without many complications -- however I would talk to a local Geek Squad Counter-intelligence agent prior to purchasing the product.
