Hi all,

I wonder what is the purpose of the 12V Aux Power In on the motherboard S2600STBR ? 

I did't find any details.

Than you by advance

It's for extra power about the PCIe connector 180W -> 216W

Hello Kiss92,

Thank you for joining the Intel community

Looks like you already found the answer. So I will mark this thread as resolved. If you have further issues or questions just go ahead and submit a new topic.

By default, the server board can provide up to 180 W of total power to the six PCIe* add-in card slots. To 

support power requirements above this limit, the server board includes one white 2x2-pin power-in 

connector that can be used to deliver up to 216 W of additional power to the server board. In an Intel 

chassis, this connector is cabled to a matching 2x2 connector on a power distribution board. A power budget 

for the complete system should be performed to determine how much supplemental power is available to 

support any high-power add-in cards.

Note: In compliance with the PCIe* specification, the maximum power supported directly from a x8 PCIe*

add-in card slot = 25W. The maximum power supported directly from a x16 PCIe* add-in card slot = 75W.
