^^ No. Everything isn't that simple.
do i specifically needs to introduce chipset, ram, fans, dvd-d, hdds, wastage, motherboard's power requirement with two graph showing wattage incriment with overclocking of cpu and gpu both thus to make it more
complex simple instead of including 75-100 watt more on 12v for all these basics and 50-100w on 3.3+5.0v
i tried to simplify the equation
my cpu when overclocked to 4GHz@1.475V can take around 170-180w and graphics card can take upto ~140W when overclocked to 1000/1406MHz which totals to ~320w and i run it on sega 2 500 and voltage on 3.3v and 12v remains always above 3.3v and 12v during stress testing (prime95+occt simultaneously) and on 5v it remains constant 5v
thus 430 can handle 560+c2d, but if you want max efficiency then its way to 800watts psu
