Accidentally installed memory while the power cord is attached to the power supply, but the computer was off. Is this bad? Would this damage the DIMM slots? Technically when the computer is powered off, there should not be any voltage supplied to dimm slots, right?

"Technically when the computer is powered off, there should not be any voltage supplied to dimm slots, right?" Unless you cut the power completely, as in switching off the power strip or unplugging the power cord, there is always power going to the motherboard. Have you booted up the system since installing the RAM? If all appears well, you probably dodged a bullet & no damage was done.
Yes everything appears to be fine after powering-on. Whew..thanks for the re-assurance.
In the olde days... if you switched of the system - even with the mains cord still connected - the system was "dead" - no volts running around anywhere. That was with AT boards... Then came ATX format and it all changed... I went through the same "gulp" moment with Dell Dimension in '98... Didn't know about the difference between AT and ATX boards etc. until a Dell tech dropped in a friendly warning to "always" remove the power cord before going inside, and removing/disconnecting anything - RAM not the least... Reason being that as you now know - there are volts still applied in various places; and RAM is one of them.
Like you I wuz lucky...
