Can this power supply handle the Gigabyte GTX 970 Windforce?

So basically I'm upgrading my GTX 660 to a GTX 970, and I was wondering if this power supply that I currently have can handle it well with no issues (the power supply I'm speaking of is in the part list).

Alright, thanks for the opinion.


Anyone have any idea how well this new system will run compared to one with a GTX 660?

Here a review of the card:
http://www.guru3d.com/articles-pages/gigabyte-geforce-gtx-970-g1-gaming-review,1.html

Expect upcoming games, ultra settings 1080p around 60fps.
For previously released games, ultra 1080p 60+fps.
Exceptions are very demanding games like Crysis 3.
