Busted Power Supply – need to upgrade!

So my Chinese printer is having issues. The printer dies while heating certain elements (mostly the bed) and I suspect the power supply (12v 20A 240w) is the culprit. Since I heard 12v power supplies tend to struggle with heated beds, I was tempted to go out and get 24v power instead so that I don’t have any further issues.

Is it possible to simply switch over to a different supply with out making any changes to the board? What changes do I need to make in Marlin (if any)?
