Front panel connections?

[Pauleduc]

Working on my 1st build, and have a question regarding how to connect the front panel wires fron my corsair vengeance C70 case to my ASUS Z87 mobo. The wires are for the power-on switch, reset switch, and HDD LED... Each pair of wires is enclosed in a connector, but no polarity seems to be indicated on the connectors. The mobo however, does have polarity indicated on the headers.

I suspect it is not too critical for the switches, but I think proper polarity is required for the LED.. Correct?

Back to the connectors, one side does have a small embossed triangle (barely noticable) ... Is this positive or negative?

The wires will tell polarity. Black is negative.

They are both black!

It shouldn't matter try one way and if it does't work flip it

The LEDs are polarized. If the connector is unmarked and both wires are the same color, just plug it in. If it doesn't work, just reverse the connection.

Switches are normally non-polarized but, when I built my current rig, after I had installed everything, the PSU kept getting tripped, as though by a short somewhere. I tracked it down to the reset switch. The problem went away when I reversed its connector. Weird.

There should be a triangle on the header. IIRC, that is the positive side. But as others have said, if it doesn't work, flip it.

Thanks.. I guess I got it right.. powered up fine and the disk activity led seems to be working.

You're right, the switches don't matter, but the HDD LED does. The writing on the connector should face OUT.

@Starrbuck.. thanks!

@Starrbuck.. thanks!

You're welcome! BTW, I've been building PCs for probably 20 years or more and I only recently learned that about the labels. I used to just try them each direction until they worked!
