Question GPU caused crashing in games.

[Techxz]

I bought a EVGA GTX 1080ti KingPin a few months ago and I have narrowed down that it was the reason behind my games crashing.

I reinstalled drives; reset my pc; did a clean install of Windows; changed power supply and none of them worked up until I under-clocked my GPU with MSI afterburner and the issues went away.

However, I noticed that when I swapped the power supply out (Corsair HX1200i) the 24pin motherboard connector wasn't in all the way from the power supply. Could that have ruined the GPU?

Shall I RMA the GPU or was it my fault and I should just leave the GPU under-clocked. I don't want to RMA it if there is a possibility that I have ruined it.

I guess that depends on how the MB internal wiring is laid out.
Also, with a loose connector, there is a risk of voltage spikes as connection appear and disappears that may cause damage to the motherboard.
