this one? https://www.newegg.com/raidmax-xt-series-rx-300xt-300w/p/N82E16817152062

they aren't very good PSU
these were all raidmax units -

most search results of reviews other than amazon say not to use it.

its possible PSU is cause of your errors.

I will get another PSU,any suggestion to buy for a good PSU,also could my 144 Hz monitor be a problem as I was using a 60 Hz monitor for quite a while without problems
