I know that the answer is yes, I should, but outlets near the setup are not grounded (even though they look like they are) and I don’t want to have wires running though my living room.
The real question is what are potential problems ? Occasional system reboots? Permanent damage to PSU? Permanent damage to other components?
I know that the answer is yes
I mean, there you go, and all of the above. I’d add in a pretty large fire risk too. I hear my battery backups kick in regularly, and we’re talking about enough power to equal a large appliance (at least in my case). It’s 100% worth it to move them to a grounded outlet.
