The psu should be enough,but most here will advice on a 850watt psu especially since overclocking.
May i ask what kind of monitor you will use. The sli of those two cards is only good for 4k.
I'll use 2 1080p monitors for now.
But after 3-4 months I'll buy a 4k monitor. So after all I'll use 2 displays, 1 1080p & 1 4K.
