980ti EVGA SLI power supply?

[JoshB]

I currently have few years old TX650M. What is the minimum wattage I will need to run both cards? I've seen many reviews on this, but it's still not clear as they state different numbers.I won't be overclocking SLI setup in the near future.

I've found this video and seems like card doesnt go over 650 https://www.youtube.com/watch?v=IHzHxshus9c Is that about right?

850w I would say! I've still got mine and used it for 2xGTX Titans, can't see you needing anymore.

This is the most common answer I saw on other forums as well, few said 850 is a must. Any particular or doesn't matter? I run a single card now on this PSU, surprised a bit that it can handle it.
