    it's fine, but a 12v 1A is cheaper and more than enough current for your project.

In the product description it says "DC 12V 8-Channel Relay interface board, and each one needs 15-20mA Driver Current." So 8 times 0.020A is 0.160A per board. I think your 2 amp power supply should work just fine.
