i, I'm building a comp for the first time, and I've run into something weird. My ASUS mobo's manual says that I need to plug a 3-pin connector from my power supply to the pwr_fan connector, but I can't find such a 3-pin connector among my PSU's cables (Ultra Xfinity 500W).
Do some power supplies not have this 3 pin connector? Or maybe I should look harder among the mess of cables? Is this thing solely for monitoring the fan speed? Thanks!
