i did tests with this smos,
i mined eth with 1050 ti doing 15.5mh + mb+ cpu + ram all complete sistem was drawing from the wall 105 watt with smos and usb pendrive 16gb
then i used ssd + windows 10 using claymore 11.7 and mining eth speed 15.8mh and drawing only 78 watt!!!
why smos consuming so much than windows 10?
Try using lower dpm stage (powerstage level in OC settings)
