I believe the tps 65217a was located on u16 on your last picture vegasthe eight chip near the lm 75.
I found this and it sounds like its on the controller :

Interesting, will the titan refuse to mine / power up if the LCD is not there rofl?!
Or tps65217 for that matter?
I was told (and it works) that you can take the LCD out of the port on a Titan to get an extra Port ..currently running 6 cubes on 1 controller using 2 1200i corsair PSU's. FYI
I can confirm I have 2 machines running like this they work great
