The UM circuit boards can handle a million watts - it will only draw what it needs. It's the other end - the heater - that you should worry about in this case. The heater I sell is only 60 watts but the same board works fine with 100 watt heaters so no worries. So with my 60W heated bed kit you probably want about 60W of additional power going to the um2go or 2 amps more power than the existing um2go power supply.
This all assumes you can find some firmware somewhere that allows you to use the heated bed with the um2go. The only firmware I know of is my custom firmware that limits power to the bed and nozzle so you can use the existing um2go power brick. But someone might create for you a special version. Maybe tinkerGnome. Anyway if you get such a special firmware please let me know so I can give it to other people who ask for it.
I mean really my kit with my custom firmware works great and heats up faster than the UM2. But if you want even faster, yes you could get a more powerful power supply and try to locate the appropriate firmware.

UM2go uses the same 2.1.x boards, they can go up to 10A as far as I know.
