I have this ECS A780GM-A Mobo, and since I bought my ATI5770 I've been having issues with vertical lines, black screen, and hypertransport sync flood error. I've been doing almost everything to fix it, no luck so far. And, after some readings I decided to check the voltages. The crappy thing is that my mobo's bios does not show the voltage, so I used speedfan and aida64 to check it and: http://img257.imageshack.us/i/voltq.jpg/ The first thing I thought was "my PSU is bad"... it's a Thermaltake TR2 750w, 6 months old. The thing is that my brother also has a ECS mobo, so I installed speedfan to check his voltage too. He has another PSU, and for my surprise, speedfan showed that the 12v was in 4,8v too. Why? if anyone knows... Are ECS mobos that bad? :S Thanks!
