Hi, I have a Dell Inspiron 545s which has a power supply of 250 w.... Ihave bought a new graphics card nvida geforce 210 which requires minimum of 300w. How can I make it work......
I see no reasons to worry here, or to upgrade power supply, why you ask, well Dell provided nice answer to this. Dell recommends this 7750 for your PC http://accessories.dell.com/sna/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=A6523076&mfgpid=192262
go to compatibility and scroll down, you will see your model there.
So you can get 210 if you want or get much better 7750 low profile, I would recommend in this case Sapphire 7750 http://www.newegg.com/Product/Product.aspx?Item=N82E16814202002
