Quick question. Might be a stupid one but here goes.

If I have a 12V max 10A power supply from the wall and I have two computers that both require 12V input and the sum of their respective maximum current draws would be less than 10A, can I connect them in parallel to the same supply?

Probably fine but I'd err on the side of caution, allow for peak current draw. If their combined draw is under 5 amps it should work well.

The 2 computers sharing a common power supply may be sharing each others' noise. The only way of knowing is if:
 1 computer works fine on the power supply by itself with no abnormal data faults;
 and then 1 or both have data faults when both are connected to the same power supply.

 If both operate normally when both are connected, then you're OK.

 Each may have power input noise filters built in... as in local decoupling plus a noise rejection coil.
