430W should be ok, The problem is that they are the wrong 430W. Back then most load was on 3.3V and 5V. Today PSUs have several 12V 'lines' just because the load on 12V is so huge. Also I am not sure that your old PSU has all the connectors needed (24 pin ATX, 4/8pin P8). So, while the output will be enough (I have a 955, 8gb ram, a 3870, several harddisks and a 450W PSU. Some time ago I measured loads with 4gb and a X2 6000 which has the same TDP. Max load was ~300W - and I had to do stupid stuff to reach that. Max load compiling/gaming was around 200W), it is not the kind the system needs. No mobo today cares about 30A on 5V. But they want as many Ampere on 12V as possible. So, you should think about a nice, non-cheap 450-500W psu.
