Hi , so i'm buying a 7850 next week and i'm also buying a new PSU . I ran a PSU Calculator it it said that i needed ~350w . So I was thinking about this PSU .

OCZ ModXStream Pro 500W

Is it good enough for my rig ?

i5-650 , 6GB 1333MHz (3 Sticks) , 1 HDD , 1 DVD , 1 CPU Fan and the 7850.

BTW , i currently have no fans installed , so would you recommend installing an exaust fan ? And which one ? Thank you

That will be adequate. The PSU has 2 x 18A +12V rails. The HD 7850 requires 208W at full load.

That translates into 17.3A from the +12V rail it is connected to. Personally, I would look for a PSU that has a bit more capacity on the +12V rail(s). Maybe 20A on each rail or 40A if it is a single rail PSU.

That's more like it! :) 
(I'm a fan of single rail PSUs, anyway)
For the slight difference in price, I would go for the XFX.
