I've an old dual x5690 system (repurposed from a 4U EEATX server chassis) that's powered by a Supermicro PWS-865-PQ 865W PSU.
I've no idea precisely how old this PSU is, but given that the x5690 is from 2011 it seems likely to be nearing 10 years old.
As the machine was probably used as a server, it's likely to have been in operation 24/7/365.
Under normal operation the PSU appears to operate perfectly normally, however when the machine is in standby mode it emits a fairly loud coil whine.
Before I contemplate the expense of replacing it with a comparable unit, I'd like to know what risks I'm running; is coil whine from a PSU that's in standby mode a 'bad sign' ?
Are high-end PSUs like this one designed to better protect system components in the event of a failure?
I'm most concerned with the motherboard, as if that were damaged the machine would be essentially scrap, as replacement wouldn't be cost effective.
