Does anyone else have a Supermicro PWS-865-PQ or have experiences of this PSU?

Hi All,

I have just gone from a dual redundant 745 chassis to a single PSU 743 SQ Chassis.

This chassis has a PWS-865-PQ Power supply, all seems to be working fine and is a VERY quiet server chassis I must say, however I am slightly concerned about one thing, if the system is off the PSU makes a high pitched noise (like coil whine), when the system is running you can't hear this unless you put your ear next to the PSU. Is anyone else's like this or can someone check?

If I had a dollar for every whining server component.

How do you like the 743 SQ?

may be better to replace under warranty?

I love the 743/745, it's not much different to the 745TQ-R800 I have, but I much prefer the silence :D

Supermicro are a pain for RMA, so want to check it's normal for this model of PSU first before putting the server out of action for a long time :(
