Hey,
So, I was putting together my first build. I saw that there was a 4 pin plug connected to the power supply and there was also a 4 pin header on the motherboard labeled SYS_FAN. Where are you supposed to plug in the case fan if there isn't any places left to plug it in?

Motherboard: MSI FM2-A55M-E33
Case: NZXT Source 210

That four pin header is a floppy power cable do not plug it into your fan header or you smoke your mb. On the power supply there going to be a 24 pin power cable.the other cables are Sata and IDE power molex. The cables that you should tag are the pci video power cables. Most power supply's now there a six pin cable with two extra pins hanging on them. The last cable can be two black four pin cables or one eight pin black pci power cable.this cable some times can be taken apart or snapped in half.
This cable will plug in near the CPU or on the edge of newer mb.

Yeah, the case has a 3 pin attached to it. It's not a floppy power one, it looks more like the front panel connector wires.

I plugged in...
Motherboard Power 20+4 pin
CPU 4 pin
USB, AUDIO, Front panels
CPU Fan
SATA

SYS_FAN is directly next to the motherboard power
