New Powersupply and some marlinsettings later heres a quick heatup of my printbed ( the blue line ). Yeah its a MK2a heatbed 
Yes why not?
Yeah i would say 120 is ok but not if i have to wait 45mins to warm up. As you can see its a lot faster. Iam printing ABS (althou iam not printing abs often) at 130deg C now cause at some points on the beds its a little colder 
4 minutes to heat up. I am jealous.
