I will first focus on compatability.
On the Newegg Page for the MOBO:
1 x ATX 24-pin power connector
1 x ATX 4-pin 12V CPU power connector
These are standard ATX PSU Connectors that can be found on every ATX-Compatible Power Supply. However, the power supply that you chose is considered not that good in the PC Building Community. At that same price-point ($...
With a 250w psu you won't get far. I think the strongest card you would be able to run is either a Gtx 750 ti, or a RX 460, which will have to be under clocked. Neither of these require an external power cable and pull around 60 watts.
Just make sure your power supply can supply enough amps on the 12v rail, and you should be fine.
I suggest the Super Flower Golden Silent PSU, available on Amazon.it. It is quite literally silent because it has no fan. Important specifications follow:
80+ Gold efficiency rating
Part number: SF-430P14FG
Has the 4+4 and 20+4 power connectors needed for this motherboard.
