Powering Stratix IV Dev kit via HSMC

Hi, Has anybody had any experience powering the Stratix IV dev kit by powering the 3.3 and 12V lines on the HSMC connector instead of the normal DC input/PCI express connector? The ref man...

The LTC4151 current monitor might see a 'negative' current through R64. However, given the only loads on 12V_OUT are U15 & U19, the current drawn will be tiny, around 1mA. Across that sense resistor that doesn't amount to enough to register a current in the LTC4151, assuming it can report negative currents at all (I don't think it can).

Makes sense. Thanks for the input!

I'll update when I check if it practically works.
