since most parts in this can take 24 V I wanted to upgrade it from the stock i3 Mega's 12 V
gonna have to order new fans for the toolhead (I thought the board on there could run 12V fans but it's a different one) and do a lot of cable management, mount the new power supply on more than one screw (why is there no standard for PSU screw holes?) but it used to be unable to hold the hotend temperature when the part cooling was on and now it easily can :)
