What kind of power supply do I need for a micro-itx motherboard with a GPU?

[devoeryan1]

I'm buying a micro-itx motherboard (with a pcie slot) and a EVGA geforce GTX 650 to put inside of my current computer, but I am confused on what to get for a power supply, because my current mini-itx motherboard only uses an external one that wouldn't come close to powering a GPU. Please help me find what I need, and I'm looking to only spend a maximum of 35$ if I can help it.

What is the current case you are using here?

Not sure, but here is my pc specs: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03534664&prodSeriesId=5295976

Scratch that, it's a mini-tower

first off, for a gaming build i would recommend ATX build IMHO.

Choose something reasonable, preferably a 550w unit from Seasonic, Antec, PC Power&Cooling, Corsair. 550w is more than enough for you to run pretty much any single GPU... i would suggest to increase the budget a little. 45-55$ will do.

I already have a fully functioning computer, I'm just upgrading from integrated graphics with the least amount of hassle. And I'm already pushing the budget.
