Firstly thanks alot for your reply. Well for my plan to work I need at least 160watt, planning on using a i5 2390t and ideally a 7850 or most likely 7770 graphics card. Picopsu's I'v found are around 160watt but what worries me is the adapters provided with them tend be much lower wattage. Does this mean they will likely act as a bottleneck? or am I missing something?
