Asus Rog GTX 3080 + TT Toughpower IRGBPlus 1250

[Kmcneil007]

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.

Hi,

Thank you for your message. Could you please check does all cables plug in a proper way? If yes, there no issue with the power supply.

Please check the motherboard and Graphic Card.

Thanks
