Do power supplies usually have temperature sensors to connect to the motherboard?

I've got the AS Rock Z77 Extreme4 motherboard, and the Corsair Builder Series CX 430 power supply.

I notice that I can see the CPU temperatures, fan speeds, etc. through the motherboard's BIOS. However, the PSU's fan speed and temperature do not appear. I notice that there's a connection on the motherboard—I can't recall what it was; either PSU fan or temperature.

Do power supplies usually have a connection to connect to the motherboard to provide this information? Does my power supply have this?

Okay thanks. I tried to be as thorough as possible with my computer and seeing what cables I might have been missing, but I couldn't find anything. Also, I imagine the power supply I have is relatively low-end, anyway, so it probably wouldn't be the model to have these kinds of features.

Legacy EVGA PSUs like SuperNOVA NEX1500 Classified also had USB connector and software to monitor these parameters. But EVGA removed this feature on later products.

For such an important component of PC, it's amazing there is no standard interface of sensor even now.
