SUMMARY: AlphaServer DS20E, Power Supplies.

Hi,

The consensus of all replies is: There's only one power connector and
only one power cord shared between the three PSUs. Additionally there
must be two PSUs operating simultaneously to have the system running.
As soon as the number of live PSUs drops below two, the systems powers
down.

I also found the complete hardware docs of the DS20E at:

Subject: AlphaServer DS20E, Power Supplies.
Hi,
Short question to the AlphaServer DS20E owners here: The DS20E has got two
hot-plug power supplies and can also be ordered with an additional third
power supply. Do all these power supplies share a common power connector
at the back side of the box or do I get three separate power connectors
when I order a DS20E with three power supplies so that I need three power
cords. I did not find that information anywhere in the specs.
Thanks a lot // Tom
