My 2950 powered off randomly early this morning.  Below are the logs from the DRAC board.  It's installed in a rack at a datacenter with redundant power, generators, and cooling.  No reports of other power outages occurred.  I also have other servers plugged into the same power strip.  I'll confirm that.. But...  I'm 99% sure they are in the same strip.  I find it suspicious that both power supplies failed back to back like noted below.  The 3 x errors are on the server display.  E1624, E1614, and E161C.

could be the system board or sensors on it failing

are there green lights on the back of both?  if amber the PSU is actually bad though would be odd if both were bad at the same time

Is the server connected to a UPS?
Have you confirmed that the UPS is not faulty, I doubt that both PSU units are failing at the same time.

I also agree with Seth have a look at the mainboard and sensors..
