I have bought an Antec Titan 550 case
http://www.antec.com/us/productDetails.php?ProdID=91550
and a
Tyan Thunder K8WE (S2895) (dual Opteron) motherboard
http://www.tyan.com/products/html/thunderk8we_spec.html
Many of the connectors from the case will not fit the motherboard because the
keys are in the wrong place.
The Audio, USB and Firewall connectors are *all* affected. The USB looks totally
odd, with no resemblance of sense. The firewall and audio can be made to work by
moving a key around I think.
USB
-----
The motherboard uses a 10 pin header as follows.
1 = VCC ; 2 = VCC
3 = DATA- ; 4 = DATA+
5 = DATA+ ; 6 = DATA+
7 = GND ; 8 = GND
9 = key ; 10 = GND
The cable from the case has a 10 pin header, but with a key in pin 1 and no
cable in pin 2. There are red cables on pins 9 and 10. So
a) A red cable on the connector goes to GND on the motherboard (odd use of a red
wire)
b) A red cable on the connector goes to a missing pin (key) on the motherboard.
c) The key on the cable in pin 1 prevents it going onto the header where VCC
leaves the motherboard.
This seems *very* odd. This makes me think someone has wired the connector wrong.
Looking at the manual for the Antec Titan case:
http://www.antec.com/pdf/manuals/Titan550_us.pdf
the pin layouts are the same as the motherboard manual. So I think they are both
using the same standard which according to the manual on the case is an Intel
standard.
Hence I think someone has wired it all wrong.
Firewire
--------
Motherboard has a 14 pin header as follows:
1 = NC ; 2 = Key
3 = TPA+ ; 4 = TPA -
5 = GND ; 6 = GND
7 = TPB+ ; 8 = TPB -
9 = +12V ; 10 = +12V
11 = GND ; 12 = GND
13 = KEY ; 14 = KEY
This means the outer 4 pins are not used, but the other 10 are all used,
although four of them are GND.
The case has a cable with a 10 pin connector (i.e. not 14 like the motherboard).
But pin 10 has a key in it. So this can *not* fit the motherboard in any way.
The manual on the case does show a 10 pin cable, whereas the motherboards manual
shows a 14 pin header. So they can't even agree on the number of pins there.
Front Panel Audio
------------------
The audio cable from the front panel has a 10 pin connector. The pinout is not
described in the manual on the case. There are in fact 8 or so single connectors
connected to this connector, so one can in principle connect it up any way one
wants using them.
The motherboard manual shows a layout like this:
1 = MIC_L ; 2 = GND
3 = MIC_R ; 4 = VCC-
5 = LINE_FPOUT_R ; 6 = LINE_OUT_R
7 = AUD_DET ; 8 = key
9 = LINE_FPOUT_L ; 10 = LINE_OUT_L
The cable has a key on pin 4, so it it impossible to connet put the connector on
the header and pick up VCC- (Quite why you would want to pick up VCC- is not
obvious to me. Would it ever be needed - perhaps for bias on microphones or
something ? ).
