This replaced my Corsair RM750i which is still working fine, however I have a RTX3080 and although it was working fine, I thought no harm in having some head room, and the RM750i was about 6 years old already. This seems to help my PC over lock a little better while also more stable now than before whilst overclocked. 1000w watt is unnecessary for most however it's was a good price 130 if recall correctly and it's always better to have a little more power than less.
