My graphics card is a gigabyte 240 gt: http://gigabyte.com/products/product-page.aspx?pid=3252#ov
I used to have a nvidia quadro fx 3450 instead of it but upgraded to the gigabyte card.
My power supply is a delta electronics inc, DPS-470AB-1 A REV :00f A picture of it is uploaded here: http://img821.imageshack.us/img821/2217/dsc01065y.jpg
Also in future for looking at graphics cards, should I be worried about my computer having pci-e 1.1 instead of 2.1 since it only gives apparently 75 watts through the slot where-as pci-e 2.0 and higher give around 150 watts.
Also apparently since my system is an hp xw6200 the power connector requires an extra cord to power the motherboard, so if I upgrade the power supply it looks like I'd have to buy a customized one.
