Unfortunately, nope. Was the first thing I tried. Here's the connection through my 50 dollar TPLink adapter - https://puu.sh/AxH2m/ff714ab983.png
And here's the connection through the onboard - https://puu.sh/AxH2Y/bf341dad97.png
And even when it does connect, the speed is absolute trash. I'm talking like 1 mb/s.
That said, I don't regret the board. But don't buy it for its wifi, that's for sure. The bluetooth works fine though, loving having that.
The extra 4 pin is for extreme overclocking. The average user, and even the average overclocker does not need it. Just using 8 is fine, but if you DO use the 8+4 that is also fine, it won't cause any damage.
Very nice cable management.
