excellent! thanks everyone. My tax return was done today and it wasnt as high as the last few yrs so not having to upgrade my psu is a plus! Faceman, thanks for the link to the EVGA, but Im in Australia not sure what the shipping fees would be but i'll hold off for now, thanks anyway.

Hey everyone, I'm looking to add a second EVGA GTX780Ti Superclocked GPU to my system towards the end of the year. Current system specs are: Mobo - AsRock Z87 Extreme6 CPU - i7-4770k (no overclock, but would like to at some stage) CPU Cooler - Corsair H100i with 4x120mm fans push/pull RAM - G.Skill 2x4gig 1600 GPU - 1 x EVGA GTX780Ti Superclocked (no overclock and probably wont be) HDD - 1 x WD Black 1tb SSD - 1 x OCZ vertex 3 120gig & 1 x Sandisk Extreme 240gig Case fans - 4x230mm fans & 1x140mm fan PSU - Cooler Master Silent Pro M850watt 80+ Bronze (Based in Australia with 240volts running through the wall sockets I'm pretty sure) I've ran through numerous different Power wattage calculators and keep coming up around the 670-750watt range and the calculator in the first page of this thread has provided an estimation of 690watts at 90% and 761watts at 100%. I'm pretty sure I will need to upgrade my PSU when adding a second card but would love if I could get confirmation if that will be required or if my current Cooler Master will be sufficient. If I do upgrade I am deciding between the EVGA P2 1000watt Platinum or the Corsair AX1200i Platinum which I believe both to be exceptional pieces. If someone can shed some light on this subject I would greatly appreciate it!
