I've often wondered if it would be possible to convert AC to 12VDC for the entire datacenter then run 12V lines to each server and only have a DC->DC 12V/5V/3.3V Point of Load power supply do the conversion. Thus eliminating power loss in the multiple AC-DC conversions and running all the extra power supply fans, etc.<br>

Doh! I had this exact idea (built in battery backup) back in '98/'99.<br>
I've even mentioned it several people since then. My boss back then<br>
thought I was nuts. My reasoning was why go through the trouble to use<br>
advanced switching power supplies to create 120vac from a 12v gel cell<br>
that will just get converted back to DC by the PCs power supply?<br>
<br>
Oh well, glad someone's doing it. How long do you think before we<br>
start seeing this all over the place? Google says they have a patent<br>
on it, but it would just be plain evil to keep such a good idea locked<br>
up, right?<br>
