Im not interested in checking power levels. I just dont fully understand what the multi rail or other option is.. I did have multi on when I did have iCue but whether its on now or not I have no idea. Just looking for advice. Not sure what the other option was, single rail I guess. I do have some serious power draw im sure and at one point I had 1080ti SLI but I no longer do.. Still I have alot of water cooling and other things like monitors, rgb, 3080ti, Eatx mobo, ram, cpu.. all over clocked yes.. chips i9 9900k if mem serves. 3600 ddr4 ram, in short a serious gaming PC when I configured it was suggested a 1200 psu.
