Im gonna need one to power a HD 3850 512mb and im gonna OC the hell outta it and my 300w psu doesnt seem to like my 3850(I can turn it on but only stays on for 20mins-1hour). I was thinking of getting this Enermax Liberty 500w because it has 500w, Active PFC, 80%+ Eff, +12v1 22 +12v2 22, and its moduler so thats cool. So is that the best powersupply for around 100$? If you can find a cheaper one thats better that would be sweet, I need the extra money for games
