I currently own three pedals, one has a power consumption of 610mW, the other has 190mW and the last one has 365mW.

Now atm i'm using a standard Digitech PS200R power supply with a daisy chain to link them all together however that only has an output of 300mA so what will I need to power them all with no worries? What size mA will I need and will all 9v power adapters work?
