How many watts would my pc need? help!!?

Question

here are my pc's specs

hard disk: 
hitachi 500gb sata3
western digital 80gb sata

ram: 
gskill ripjaws 4gb dd3 with heatsink

processor:
amd trinity a10-5800k 4.2ghz fm2 black edition, stock heat sink and fan

motherboard:
gigabyte ga-f2a75m-d3h

video card:
sapphire hd 6670 1gb gddr5 128bit

2x 80mm fan, 1x 120mm fan

*it is running in dual graphics mode (amd radeon hd 7660d + 6670 dual graphics)

im currently using a GENERIC 600w psu..(i read from some articles that a generic psu can only handle 250w of power, dont know if its true :(.. I play games like bf3, skyrim, assassins creed3, black ops 2 and run it in high settings

judging from my specs and heavy gaming,do i need to buy a non-generic/branded psu like hec, huntkey etc? or continue using my generic psu?

I'd use a branded 650W PSU, should be more than enough.  Also, 4GB RAM is plenty.  If you use task manager, it is evident that consumer applications (including games) don't even come close to using all that.

Minimum PSU 700W-800W. *

400W  @80%efficiency =  320W
430W  @80%efficiency =  344W
450W  @80%efficiency =  360W
500W  @80%efficiency = 400W
550W  @80%efficiency = 440W
600W  @80%efficiency = 480W
650W  @80%efficiency =  520W
700W  @80%efficiency =  560W
750W  @80%efficiency =  600W
800W  @80%efficiency =  640W
850W  @80%efficiency =  680W
900W  @80%efficiency =  720W
950W  @80%efficiency =  760W
1000W @80%efficiency =  800W
