What is 3 Pin Blue and Black Power Supply Cable?

[RobDMB]

I am putting together a case and from the power supply there is a blue and black cable that I have no idea what is is for? Could anyone tell me if this shold be connected to something? Thanks, Rob

Sounds like a fan connection. What's the make/model of the PSU?

The power supply is a Smartpower 2.0 350 watts. I think it is a fan connection. I'm wondering do I connect this to the motherboard where it says chasis fan or no - would chasis fan simply mean the regular case fan?

Anyone know if I should connect this cable? I want to boot this system up but I'm just worreid about this cable.

Just connect it to a chasis fan connector on the motherboard. I have a 400 W SmartPower and that's what I did. However, it's not required, according to the manual, it just allows fan speed monitoring.

It's the cable that the Antec PSU uses to vary fan speeds for the PSU fan and fan-only connectors. Connect it to a chassis fan header on your motherboard like he said...
