I am wanting to put a video card in it, but the machine only has a 220 watt power supply. The biggest supplies Ive been able to find so far is a 270 watt. Does anyone know if bigger wattage supplies are made that will fit and if so where I can find them?

Kind of basic information to have it you want someone find equal or smaller. Have you looked at micro ATX form factor PSUs? http://www.newegg.com/Product/ProductList.aspx?Submit=E... How about mini ATX form factor? http://www.newegg.com/Product/ProductList.aspx?Submit=E... The mini's at newegg only go to 300w but that is a little more than the 270w you listed. Further, if you can identify the form factor then you can broaden the search with google. m 0 l hunter315 a c 288 ) Power supply a c 202 U Graphics card December 6, 2009 10:29:22 PM Because its a slimline it seems to take stupidly shaped long skinny PSUs rather than the standard size, does it look like this seasonic? http://www.newegg.com/Product/Product.aspx?Item=N82E168... If so then you can upgrade to that seasonic you should be able to run a 4650, but you will need to make sure it is a slim card so that it will fit in your case. m 0 l Can't find your answer ? Ask !
