Keep your current power supply. Just get one of those daisy chain cables...

Just be sure not to exceed that with the total from the pedals you have chained together. The manuals for most pedals will specify the current rating. If you don't have the manual, you can usually get it form the manufacture's website. Boss has all of their manuals available online, and they always specify the current draw.
If you can't find the manual, or in the rare case that a manual doesn't have the current rating, you can measure the current yourself. If you're using a standard multimeter, you'll have to splice a power cable in order to measure current (you can always repair it when you're done). If you don't have the means to do that, Truetone makes a meter for this exact purpose...

Out of the ones on your board, the digital delay and loop station are going to be the biggest draws. The dirt pedals aren't going to use much at all, and the wah will be less than 1mA.
