Report Asus Rog GTX 3080 + TT Toughpower IRGBPlus 1250 in Digital Power Supplies(Smart Power Management) Posted February 16, 2021 I scored a Asus ROG GTX3080. I installed it in my current system to replace a Asus ROG GTX2080. Now when I boot into the bios of my Asus Maximus hero XI the board doesn't recognize the 3080. I thought a Thermaltake Toughpower IRGBPlus 1250watt power supply would more than handle the video card. I moved the 3080 to my older pc with a 750w power supply and it worked like a champ. SIgh! Not sure what to think now. Any ideas with be appreciated.
