PSU causing blue/cyan screen flickering?

[Wasted4440]

Hi everyone, I currently have a Thermaltake TR2-600W PSU and a GTX 760 GPU. Previously I had a GTX 550ti and a stock 400W PSU. With both those setups (I don't quite remember how it ran for the short amount of time I had the 550ti and 600W setup), I occassionally get a blue/cyan flicker on my monitor when under load (Playing games like War Thunder and Total War on pretty high settings) that would disappear when I exited either game, or if I jiggled the VGI/DVi cable.
I'm currently planning on upgrading to a Corsair CX750 PSU, and was wondering, might this solve my problem? I've tried various VGA cables, but all seem to have the same issue. Thanks for your answers!

Thermaltake TR2-600W PSU < That is a very poor power supply , replace it.

CX SERIES are bad with poor capacitors.
