No, you're fine, that psu will do for two 7970 CF.
It's a quality psu with more amps/wattage than required.
Nothing to be worried about.
I wanted that name
Thanx for that. So would oc be out of the question. I suppose with 2 hd7970c's windforce i would not need to oc. I have 1 hd7970c in my build which has the latest driver on it. My question would be when adding the other hd7970 for xfire would i still have to wipe the driver first then update both together with amd catalyst. I enjoyed ths build but things are getting tricky for me adding the 2nd card. I ready somewhere i need to download driver to desktop, wipe driver on the card then go in with driver sweeper to make sure all files are wiped. Unsure about using 1 or 2 xfire bridges, apply driver, make sure xfire is enabled then wipe the sweat from my forehead phew & reboot.
