yes, the power supply cares, the whole point of the power supply IS to convert AC to DC, and step it down to a usable level.:P
The problem with switching to DC is not in replacing the power supply, but upgrading the wiring in the data center (plus other equipment like the UPS', which in any decent server room will be HUGE mothers)
The argument against this is that the upgrade would be too much of a huge cost/PITA to justify what could be only a small increase in efficiency.

well, dc will stop your heart, ac will cause you to fibrillate. Both can cause massive tissue damage. So 480v 3-phase is just as scary.
