hi, i just want to ask some advice from you guys regarding on choosing what wattage should i prefer in a PSU

specs:

mobo- p8b75-v
CPU- i5-3570k
GPU- xfx 7850 double dissipation
RAM- 2x 4GB
case- fractal design r3
monitor- HPL1706

the pc is meant primarily for gaming..

i have a 650w PSU but i was not convince that it is a good one it came from DUBAI and its brand is DELCO made in china.. and the thing is that it has no fan and it has word that say pentium 4.. even though i dont know a thing about computer i am certainly sure that i dont trust this PSU of mine.
