In reply to the connectors problem. There are a number of water cooling kits or water cooled Titan versions that may offer better clearance for connectors than the reference shroud design. Attach is a pic of one I found. May be go that direction? You would have to hunt out the most useful and do a bit of measuring and checking up to see if it would fit though. HTH

Summarizing the topic there are some solutions (not perfect although):

1. (the one I applied) is to slightly bend pins for power-switch and connect an original chassis power-switch cable to them (only one cable is connected; rest of them: hdd led, reset, etc. are disconnected). Disconnected are also 2xUSB2 front panel cables (luckily front panel USB 3.0 is connected with a separate cable near to 24 power cable), front panel audio is disconnected and the external panel for overclocking is also out of use (what a pity).

2. Extreme solution - cut the cables and solder them on your own :)

3. For those who does not want to bend pins (neither soldering them )- there is a red "Start" button mounted on top right corner of the MB; which is light up and looks very attractive. But this requires an opened chassis to access the button and a chassis front panel is still disconnected.

4. If these TITANs were mine I would definitely go with watercooling - I have one Titan with EK water block which is slim and occupies only single PCI express slot (in term of width) (and temps are incomparable - 40C vs 80C on air) - for me this would be the first solution. Additionally watercooled TITANS can be easily overclocked and are about 20% faster and still cold (43C) at stock 1.2V (and silent).

5. This is the answer/suggestion from Overclock.net forum - use PCI express raiser cable http://www.ebay.com/bhp/pci-riser-cable. The chassis we've used Corsair 900d has additional two slots for moving the card down and allows using the raiser.

6. Throw fourth TITAN out of the window and be happy to have all cables connected :ugeek:

Hi guys-

Well I've been lucky enough to have built something like 15 of these quad GPU machines over the last year (I know, I have an illness) so I know a lot about this. It perplexed me too at first. Basically you just have to bend those wires 90 degrees as you seat that last card and all is well. No issues with all of these machines.

BTW- Just so you know I've gone through A LOT of ASUS boards. They seem to be very prone to shorting. On the other hand every Gigabyte board I've bought (probably 6-7 so far) has been flawless.

That's my personal take on this. It's super fun building these incredible machines and I just love running Octane through them.

Good luck!
