Define R5 or Define S?



But you can get the R5 without a window? And i know the GTX 980 Ti is overkill for a 1080p monitor, i just wanted to see how many watts it uses, so i knew which PSU to pick. :)
 


R5 comes in several configurations. I have a Titanium r5 without a window.

As I understand it the big difference between the R5 and S is the S does not have OD bays.
