SOCKit HSMC current available

I’m using the SOCKit to power a custom expansion card through the HSMC connector. The user manual for the SOCKit lists current the HSMC 12V can provide as 1A. Yet the 12V is fused for 2A on the SOCKit. Can I use the full 2A or is there another limit I am unaware of that reduces this to 1A?

From the schematic, it looks like the 12 volt supply comes directly from the power brick via the fuse. That, less the power used by the board, the ability of the 12 volt traces on the PCB, and fine links on the connector would be the limit. Personally I wouldn’t want to risk my expensive board by drawing more than the 1 amp specified in the users manual.
