Sorry about the long link. My question is what power supply should i use. I was thinking a 12v 2amp. On a side note do i look at the input or the output when choosing a power supply

Thank you

    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.
