Generally you'll use CIM to monitor your hardware which includes power supplies/etc. You can get this information through ESX(i) by looking at the Hardware Status which gives you a graphical breakdown of your components. You should also be able to get this through syslog but if you're looking for the raw logs for some of the hardware components, you might be able to see it here:
/var/log/ipmi/0
There's a file called sel which looks like it might contain some info about PSU
[root@esx-host-1 0]# cat sel 20090727133010: Assert + Event Logging Disabled Log area reset/cleared 20090727133039: Assert + Power Supply Power Supply AC lost 20090727133039: Assert + Power Supply Redundancy Lost 20090727133140: Assert + Power Supply Power Supply AC lost 20090727133140: Assert + Power Supply Redundancy Lost
Majority of the logs is the raw data that is used to CIM/etc. You probably will get more detail information by using the CIM API or vSphere API to extract the hardware information.
You can take a look at this script that I wrote to help monitor your hardware and you can setup scheduled runs and it'll email you the report;

Not sure if there's any other location, again the recommendation is to either utilize agents to monitor the hardware or the CIM API to retrieve this information, that's what that API is for
