Product review (5 stars): Compatible with all Reference GTX 980 Tis
I own the Zotac GTX 980 Ti reference model.  Although it looks awesome with the reference cooler, it sadly did not come with a backplate (NVIDIA Reference Design).  I placed an order for this EVGA backplate as it clearly states that it is compatible with all reference GTX 980 Tis.  They were correct.  I received the backplate, removed 7 screw, put the backplate on and put the 7 screws back in.  It took about 5 minutes and now it looks much better and now the PCB is protected.  I can't say for sure that it lowers temperatures but I like it regardless since it completes the look of the card.
