Gameplay has a ripple effect

[sppr356]

I recently installed a new 600w psu for my rig, after my old 800w started showing signs of wearing out. I started playing Tomb Raider and War Thunder, I noticed a sort of jumpy, ripple effect when playing. Not lag or poor fps, just a constant wave of slow/ normal game speed. I was wondering if the psu isn't quite powerful enough? Or if there is a different problem entirely?
Thanks for any help.

The PSU could be generating electronic interference that is affecting the GPU and causing the ripple effect.

What would cause this interference? Would returning the psu and getting a new one be simpler?

That's hard to say. What make and model is the new PSU? is it a good quality brand like Seasonic, ETC?
According to Nvidia,The 760 only requires a 500Watt PSU,

So a 600 Watt should be more than enough, unless it is an "El Cheapo" brand.

The CX600 is considered a "builder's grade" PSU. Not bad, but there are better ones out there. I would certainly consider getting an RMA and returning it at this point.
