Yea 1200w is not utilized unless you have 2 3090s and sli or plan on doing some ridicules overclocking on both the CPU/GPU for a single 3090. 750/850 is sufficient. Those are all marked up at 400$+ as well where as 850w and below are 250 and under.
If you needed a 1600i then you either wanted some uberly silent psu or do some other heavy stuff such as mining
^^^ Cute....thanks I wasnt aware, not sure what I was thinking
