Ok so I have been trying to figure out why my system crashes when playing really demanding games like GTA 5 or COD AW both game are known for issues. I can play other games like Metro Last Light, Return to Castle Wolfeinstine, Batman Arkham Origins, Saints Row IV all with no issues. Is it just crapy games or is my system under powered. Here are my specs: Intel 4670K i5, ASUS Z87 Plus Motherboard, 2x 8GB DDR3 1600, 2x ASUS DCU2 Radeon HD 7850 2GB, 3 Sata HDD's 7200RPM ranging in sizes, PNY 240GB SSD, Internal Blueray Drive, 4 140mm LED case fans, 140mm LED case fan, Dual LED Fan Corsair H55 water cooler, 1 dual cold cathode lighting system all being powered by a Antec 700W power supply. I have used

estimate how many watts it should be. Extreme Outervision says 550W Power Supply which seems really low, then ASUS says 850W Power Supply. So which is it, do I need a more powerful power supply? I have noticed on this system that the +12V is always under 12V not by much usually 11.9 but the other system I have is always above like 12.2 and stuff not sure if this is proof in its self that I need more power or not.
