Externally powering mk2a heatbed

As my electronics are broken, how can I control the PCB heated bed directly from the power supply?
It is 12v 20A, but don't know what resistors should be used.
What power is needed to maintain ~100C?

Well, just connect it directly - it will only draw the current it needs. The problem is, you will have no temperature control.
