Is my pc's power supply enough?

Solution
Yes. Note that right there in your build it specifies that 448W is required. I like to add another 100W for extreme overclocking of the CPU and another 100W just in case. That gives you 648W. So, unless you plan on going with CF 7970's in the future, you are set. If you want to go with CF 7970's later, get a 850W to 1000W range power supply.

''No you don't. Explain please.''

well for the difference of price between 650 and 750W psu its better to have a 750W one ...if in the futur he want to had a
crossfire gpu he will be ready for that

and by gold rating .. i mean the efficiency of the power supply ... becaus you must calculate the power taken by the ac outlet and the real wattage delivered to the pc ( always lower then the ac outlet )
