[SOLVED] Red Dead crashing after new UPS

My friend has an RTX 2060, R5 1600 (14nm) 2X8GB 2400Mhz, ROG B350-F, VS550 (it's the one before the gray label one)

He installed a UPS. changed some graphic setting in game, and now it's crashing. I'm trying to see if it's the UPS (I think so)

It's a Microtek Legend 650VA/360W UPS.

Thoughts?
 
Solution
Take the UPS out of the equation, unplug the computer from it and go directly into the outlet. If it stops then you know its the UPS, its entirely possible that some sort of surge protection/voltage regulation in the UPS is faulty and tripping when the computer starts drawing higher wattage.
