PSU Advice

[540media]

Looking for a bit of advice as to whether my current PSU is powerful enough (for the time being) or if I need to upgrade.

Currently I'm using a Corsair RM650x to run the following build

i7 5820k
X99-SLI
32gb corsair ram
1 x 256 ssd
2 x 1tb hhd
1 x 4tb hhd
GTX 960

everything is at stock speed. I'm looking at adding a 1080 along with the 960 (this system is primarily used for 3d rendering with octane), will the RM650x be enough or do I need to upgrade?

cheers

Thanks,

Got no other addon cards, running 5 fans and just usb keyboard and mouse

If I eventually upgrade to 2 1080's do you know what sort of wattage PSU I should be looking at? would 750/800 be ok or would I need more?
