You will need much, much more than 150watts. The minimum requirement for the 7 series NVIDIA cards is 350watts, I believe. I'd say something like a 550w would be sufficient with decent amperage.

Yes, I'd go with the 600w as well. I'm using a 650w for my computer which will eventually have a somewhat-alike configuration to yours.

This post is probably useless; but just thought I'd edit what I said earlier, I think the 7 series requires 450watts of power minimum, not 350; I think 350 is the 6 series.

Correct Hyrox.

I would go with that Seasonic 600W or another higher end psu. I got the Enermax 600W Noisetaker after my Antec 550W had problems. This psu yes has 50 more watts, but is also a much better psu. That looks to be a somewhat power hungry machine. Believe me, you'll end up spending more if you don't get a good one in the first place.
