"might do it"

If (= provided that) you can trust the manufacturer for that statement 
"300W PS".
I tend to be wary of such statements. The maximum current provided for 
each voltage output would be more significant than the wholesale 
advertisement of "300W PS". Your calculation might be well within the 
limits in general but what if the load for e.g. 3.3V goes up to 12A but 
the PS is only able to deliver 10A? It might be well able to deliver 20A 
for 5V and 8A for 12V but your load does not need 5V or so much at 12V 
but more on 3.3V or even 1.8V. So be careful and have a look at each 
needed supply voltage and its power rating.

all by rule of thumb - and it's a very thick thumb with carpal tunnel 
syndrome I reckon.
