PSU 400W Be Upgraded to HD6850 with 18W Power
My PSU is 400W, max 450W with GTS 250 1 GB, and I want to upgrade my video card to HD6850 with 18W power lower than GTS 250. Could this be possible or do I need to replace my old PSU to a new and upgraded model? I am confused. I want to know in advance in order for me to avoid some problems in the future, if I decide to buy it. Please give me some advice. Thank you.
