Intel motherboard (S5500HCV) 'Auxiliary Signal Power Detail' connector


Has anyone come across a connector on Intel server motherboards labeled 'Auxiliary Signal Power Detail'?  Know what it is, and if it's needed for operation?  Documentation on this is pretty scarce.

I purchased a high-end Thermaltake psu to pair with this motherboard (Intel S5500HCV) and it doesn't have that connector.  Have tried posting to the server section but must be 'approved' and the moderators are asleep at the wheel.

Hi Sylvain,

Yes, I'm sure I can buy an Intel psu and get it in sometime next week.  Was hoping to use the one I already have.  If it's optional, I'll probably be ok.  I did come across a Technical specification for this m/b as well as a couple of others.  <>  I'm printing that out now to review it in detail.  Not sure if it will answer the question yet though.


I put together the server and tried it.  Yes, it does need an Intel p/s.  The connector provides feedback to the p/s about impedance and dynamic load requirements.  The one listed is an AXX750WWPS p/s.  I'm getting the impression though that this will only work in an Intel chassis.  Can anyone verify that?


Hello !

with no datasheet on Intel's site, that's anyone's guess I believe... unless someone has actually seen one.

Sorry I can't help you further.

Hi Syldra,

No problem.  I'm just going to return this one or put it up on eBay.  It's too much of a pain in the butt to deal with, when other motherboards from different vendors can run the application I need just fine.

Thanks much!
