Disclaimer- I have no 3-phase equipment, nor any 240V-required
computers so take this with the contempt it deserves.
For the PSUs (for given machine X that does not have 3-phase motors for
blowers or drives, or another thing that requires the rotating field of
3-phase), aren't they composed of (roughly) 3 standalone PSUs that
convert the incoming power to a DC-source feeding the rails? Therefore,
(and especially if it is wired phase -> neutral rather than
cross-phase), provided the voltage supplied by a single-circuit would
be within the range of acceptable input voltages for the PSU, couldn't
they be driven by 1 split 240V circuit (driving 2 at 120V
hot-to-neutral) and a third 120V line feeding the third PSU?
