What kind of current sharing features?<br>
What do they look like in PC power supplies?<br>
<br>
<br>
I think in general, the answer would be no you can't
combine them.<br>
There's a good chance the output regulation interferes
with each other.<br>
Best case would be not much output power from each, worst
case wild and<br>
strange oscillations exceeding output voltage.<br>
<br>
It might be worth a test, but I'm not confident to
guarantee that each<br>
power supply and the load survive that undamaged.<br>
