Antec PSU w/2 wire, 3 pin connector; fan control or thermal sensor?

[RoadStar1602]

Just got PP352X for a Lian Li case to power the Black Pearl (ASUS CUSL2-C BP), and there is a l-o-n-g 2 wire (black & white, on the outside pins), 3 pin connector from the PS. According to the MB manual, the outside pins on these connectors are for rotation signal, but the header for this is 2 pin, closely spaced.
I get no response from the Antec website, and no indication of the purpose of this lead on the retail box or w/included print materials.
Anyone?

Ask the place you bought the PS from. Most likely it's the tach output from the PS fan and would connect to one of the fan headers on your mobo, if you have enough for it. All your fan headers should be 3-pin, just make sure black goes to ground and white goes to tach, NOT 5 or 12v!

Thanks, but I hardly think anyone @ Best Buy could help me much.

So you are saying that this is just to read the PSU fan RPM?

Finally got it from updated materials on Antec site:



<< The power supply is also equipped with a 3-pin fan signal connector. Connect it to one of the fan connectors on your motherboard. You may monitor the fan speed of the power supply through your motherboard BIOS or through the monitoring software that comes with your motherboard. >>
