EVGA G2 850W is around £100, but very good quality and more than enough room for SLI 980ti and overclocking

850 is fine for all around overclocks on the z97/z170 platforms. It's pretty tight on x99 though.

It's fine as long as you stick with the stock GPU bios. The minute you go over to overclock.net and decide to flash your bios, 850w is not enough. With my setup (sig) which is similar to yours, I have pushed over 900w from modifying my bios.

i use msi afterburner for overclocks so is it ok to clock both cards at 1500 mhz and 10 percent on the powerlimit ?

You will be fine with that because you are still using the stock bios overclocking with MSI A/B.  What I was talking about is completely overwriting your bios to a custom one with higher power limits and voltages.  Some people are running 1.255mV (which I am using) all the way up to 1.281mV @ 425W max power target at 121%.  If you were to do that, you would be running north of 900w and I have seen it hit close to 1000w (using a different bios).  If you do not plan to do any of that, an 850W PSU will be fine.
