Okay, so I have an HP Slim (low-profile), and it has a 7100 GS (gpu) video card. Which isn't the greatest. I'm looking to upgrade this card...so I can do things like play newer video games; and what now. The only draw back is my computer only has a 160watt power supply (psu). The minimum requirement for the card I have linked down below is 400watts. What the....? How am I going to fit a 400+watts power supply into a low-profile computer (this thing is tiny)? Are their power supplies especially designed for my size of computer (low-profile/sff)? Or will a regular size power supply work just fine? Link to the card I'm looking at: http://www.newegg.com/Product/Product.aspx?Item=N82E16814162016 Anyone have any links to compatible power supplies? 400watts+??? ANY TIPS OR ADVICE WOULD BE GREAT. This is my first SMALL computer, and I don't know a whole lot about the parts.
