[MinnowBoard] MinnowBoard Max Power Requirements?

[David Rolfe]

Hi,

I nearly got my Amps and Watts muddled up, as I had previously read on 
www.elinux.org/Minnowboard:MinnowMax#Design_Files that a 2.5 W supply is 
adequate, and it even gives a few examples of suitable models, none of which 
are unfortunately UK specific!

My plan is to us a 4 Amp supply, similar to the one on 
www.ebay.co.uk/itm/310818455475?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT 
which should be sufficient, should it?... even with a 2.5" SSD drive 
connected to the USB 3 port?

If my electrical calculations are correct this equates to a 20 W (4 x 5) 
supply which looks more than OK to me!

Thanks,

David (Rolfe)
