Three different GPU's is predictably weird

[Serin]

So after adding a 1080ti to my 3d design rig the other day, I realised that the 1050ti I was previously using to drive my monitors would fit under my titan x quite comfortably in the sabertooth x99's bottom slot.
Being a 3d nerd, I'm always for adding more render power. So I installed it, plugged my monitors into it and installed new drivers and went about testing it in blender.

This happened. But only when it went into 3d mode as I put blender into render viewport. 

Each of the cards works by itself, and they all work in combinations of two of them, but it seems adding a third gives the system fits of some kind - an Nvidia control panel message of ")"
I'm fairly certain it isn't an overall wattage problem as blender cycles only eats about 6-700watts rendering with the titan and the 1080ti.
I am also not aware of any issues that would occur given the 1050ti being at 8x, whereas the other two are at 16x

Full system specs:
5960x @ 4.5gz
Sabertooth x99 (latest bios)
64gb ddr4
Top slot - 1080ti
second slot - titan x maxwell
third slot - 1050ti
AX1200i
Handful of SSD's and spinning rust drives. No PCIE drives though.

I've since taken it back out because well... I've got work to do - but I'd love some ideas as to what might be causing the issue.

Interesting, I have heard that Nvidia drivers max out at 6 cards bu this is just weird.

the 1050ti wants to listen to some music while doing work (x)

 

What if you turn the Nvidia resource monitor off?

The 1050 Ti is making beautiful music!

That did it! It sings the song of its people no more.
Of course, now I worry that its just hidden a major issue that nvidia was trying to tell me about. Ah well.
Thanks!
