t9300

Hi all, Can I upgrade from my current dual core T9300 to a QX9300. P socket is correct I know that much (PGA478). I have a 65W transformer, (Q1) is this enough power? TDP is 45W on the Qaud and 35W on the dual core. It runs the dual core without issues; battery as well (10.8v dc, 4400mah)...
