So I can´t say for sure but following this link: http://www.cnet.com/products/asus-hd7850-dc2-2gd5-graphics-card-radeon-hd-7850-2-gb/specs/ The GPU is about 260mm in lenght. You would need to litterally measure your case for clearance like this:
And if you get more than 270 mm it should fit
Take care as well the height in some extreme cases could be you can´t close the case
