Hey guys ive recently bought new parts for my rig and well the last thing i bought was an OCZ power supply 700Watts MODXSTREAM PRO and well next week when i get paid im planning on buying [BFG] GTX 260 OC MAXCORE 896MB GDDR3 or an ATI card 4850 1gb or a good ATI Card.. Well i was wondering if my 700Watts PSU would be able to handle the 260 or any other type of card similar to that. The Specs say that the 260 needs a 525 Power Supply with 38A on the +12V Rail but my OCZ only has 25A on +12V1 and 25A on +12V2 both +12V combined =552W i mean is that enough if i want to maybe put another 260 later down the road ??? Another question if i overclock my i7 920 to something stable 3.0+ghz how long will it last and will the power supply handle the overclock with the card? If not so i can return it and pay the difference for atleast 750 - 850 Watts hope you understood please thank you for help
