Is there a feedback sensing line for voltage regulation
in the computer supplies that is accessible?
One trick I've seen done is to diode OR
the supplies, with the sense lines on the common
supply bus, after the diodes. *MACom did this
on the massive switchers we used in our old fiber
nodes at work.
There are no sense lines available externally on a PC power supply. *You might
take a look at the article on modding PC power supplies athttp://www.pavouk.org/hw/en_atxps.html. *It shows a typical schematic (albeit a
bit aged now). *Look at it and you can see where you might bring the sense lines
out of a "master" unit and run them into the "slave" units. *No guarantee that
it will work, but I'd rather try that approach before the diode or resistor
solutions.
Of course, your PSUs will be different from the schematic in the web page, but
it should be similar enough that you can figure it out.

Life is like a roll of toilet paper; the closer it gets to the end, the faster
it goes.
As long as they use the same IC it shouldnt be too difficult to
figure it out even if the rest of the circuit is different.
