The larger one is rated 5V/3A (came IIRC as part of the 'UP Board' package) and the small one is cheap chinese crap rated 5V/2A and also the PSU showing 'best GbE performance' (since it provides 5.25V?). After I found my '5.5/2.1 to Micro USB' adapter (in the lower middle of the picture) I could use the next 2 PSUs.
