What's that funny connector ...?

[Hans L]

I just received my Lian-Li PC-A10 case. Coooool! But since this is my first build, and I am somewhat of a greenhorn, may I ask those of you who already have this case, what is that 2-pin uncovered connector that is attached to an old-fashion power adapter and that came separately, that is, was not connected to anything in the case?

That may be a temperature sensor? at the end is the 2 pin thing joined?
