i'm currently running a raidmax 1000W PSU on my first build. i've seen the light and recognize the fact that i need a better quality power supply. i'd like to know approximately how much wattage i should be looking for. the 7970s use 250w a piece, so would a 750w power supply be sufficient?

this is the PSU i have my eye on: http://www.amazon.com/XFX-Edition-Modular-Certified-P1750BBEFX/dp/B00B88Z314/

build:
p8z77-v motherboard
i7 3770 (stock)
xfx 7970 black edition (CFX) (stock)
g.skill sniper 8gb 2133
250 SSD
2TB western digital black HDD
2 140mm case fans
3 120mm case fans

thanks in advance.
