    this is for the connector, but you should also have a look at the main board schematic to see how much its power supply is able to deliver.

    Go to www.samtec.com and look up the specs on the QSH (or QTH) connectors. The ASP-... connector is just a custom version of that. There should be a document there that talks about current capacity. Off the top of my head, I think each pin can handle 1A and the ground bar in the middle something around 7A.
