You're right, that is an EVBot and it's handy on the 780 Ti Classy as you can set voltages profiles and adjust on the fly. EVGA is working on a new EVBot, the EVBot II, but that might end up as an APP from what I hear. Running Firestrike Extreme with 780 TI Classy SLI @ 1493/1507 MHz with vcore set to 1.4250V in the Classified software controller I measured the vcore to 1,5250V with DMM on the top GPU. The rig pulled 1780W from the wall in the first GPU-test. Luckily I'm using two 1200W PSU's when benching these monsters in SLI.
