the heatbed for the I3 pro C is 96W, yours is 115-144, maybe too high for the PSU...and is your heatbed resistance too big?

according to Ohm's law, P=I*U=U*U/R, then you can konw the theoretical resistance. I too high or too low will affect the temperatures.
Also you can find a more powerful PSU to verify whether the power is enough or not.
