Lexa S help with cables!

post #1 of 10
Thread Starter 
So I understand the fan cabling system but I have no clue what the black cable (labelled TKG?) is for! It has 2 molex connectors (1 for inserting and 1 for insertion) and a 3-pin connector all on one cable.
My best guess is that it serves as some sort of power router that is able to conveniently divert power from the PSU to some device. And this device can't be a fan, because the 3-pin connector on the black cable is for insertion!
Please help!

oh and also on another note, I have an ASUS that comes with a convenient system panel connector but I have no clue what 4-pin goes into the speaker-ground-ground-5v =(
It is apparently for a chassis-mounted system warning speaker, which allows me to hear system beeps and warnings, but I have a suspicion the Lexa S doesn't come with one. Could this be confirmed?

Sorry for the long post but thank you in advance! =D

That molex connector is a pass-through most likely and one end gets plugged in while the other end you can plug something else on that if you'd like. That molex is most likely for your ESata ports on the side of your case.

You need to find out if your ASUS mobo already has a BIOS speaker built in and if so is maybe why you cannot find a connection for that speaker they give you - that speaker is in case you don't have one already on your motherboard but again you need to find this out or give us the model number of that board.

The ASUS I'm using is the ASUS P8P67 ATX P67 LGA1155 DDR3 2PCI-E16 2PCI-E1 3PCI Uw.SB3.0 Sandy Bridge B3 Motherboard.
Hmmm are you sure the molex is for the ESata ports on the side of my case? because i have a SATA connector coming from the front of my case and I assumed that it would be for the eSATA port =/

Oh the motherboard has a Q-connector for the speaker-ground-ground-5v 4-pin. But I assume it's supposed to be a chassis-mounted system warning speaker so I think there should be a cable from the front of the chassis that should connect to this =/
problem is, I can't find it (if my assumption is correct)

That molex should be to power the Esata - can't be anything else. My CM 690 II Advanced case has the same with a Esata and a molex.

Your motherboard does NOT have a BIOS speaker built in and that one that is supplied with the case should be connected and there's a spot on the motherboard header for that - your ASUS motherboard manual shows it as I'm looking at it online right now in PDF format - but you have the book so it has to be in there to where and how it connects. Just remember that the red wire is the +5V the rest should be easy to figure out.

The manual has that illustrated as well again I see it - read your manual carefully and connect.

Oh ok, so I realized that the thing is called an internal PC speaker. Yeah my motherboard did not come with it. Is this really necessary for the PC to function? and what component does it come with?

Well if something is wrong or goes wrong you'll hear beeps and those beeps in the pattern it does will direct to where the problem is.

Going to bed - nighty night.

Cables from the Lexa S is as followed:
Fan - 1 Male Molex, 1 Female Molex, 1 3pin all from one cable line

Fan Control - 1 double sided Molex (Male and Female) label Fan Control
- A pair of 3pin male cables labeled "1" and another pair labeled "2"

Front Panel - 1 double sided Molex labeled "Power LED" for the front left and right strip
- The assorted wires that'll be connected to the motherboard

From what I can tell, according to your description, that wire is most likely a fan cable.

An internal system speaker is not necessary for your system to operate. It just comes in handy when/if an error occurs during bootup. The series of "beeps" from the internal speaker will help indicate what the problem is.


Hope this helps
