I find it strange this problem is’t spoken of on this forum (or can’t find it) My Mobo is in RMA now because after running 3 months great on one morning after pusing the powerbutton nothing happened. No lights on the mobo, no fans, no waterpump absolutely nothing. I brought it back to the shop for an RMA. Later i read on Hardforum of more of these problems and that removing the cmosbattery helps. For me it is no option because my system is watercooled with a vertical mount of the GPU so i can’t reach the battery without disassamble the system. I hope GB finds a solution soon because if it happens again after the return i wil replace it for an Asus. I have and 10years old system with a mobo from GB which gave me confidence to buy GB again. The Master has great specs but i need a mobo which i can trust.
