Title: UD9 Molex connectors
Post by: CraigyT on August 19, 2010, 10:25:49 pm
Hi,

The UD9 has 2 additional Molex connectors on the motherboard which, according to the manual, must be used if more than one graphics card is connected.

Unfortunately the Molex near PCIe 1 is covered by the North bridge cooler.

So, should the Northbridge cooler be left off or will power to one Molex connector be enough to ensure system stability?

Yes bad design really isn't it?  Can you customise the heatpipe cooler to allow the molex connector to be used? I think it should only mean cutting or "adjusting" some fins. If you are water cooling you won't need it anyway. Where is the second molex connector I could only see one?

Its a design flaw guess they have to make a rev. 1.1 or find a flat Molex adapter?  

you shouldn’t have a stability problem if you got a good PSU and really its only needed if your doing a NVIDIA 4-Way SLI and ATI CrossFireX setups.

Its at a right angle at the bottom.

Yes having just studied the setup I would agree. One molex should be enough unless you plan to fill all the slots.  ;D

For the record..... and without wishing to tempt fate  :)   

1 molex connection (Bottom of the board) appears to be enough for Nvidia GTX 480 SLI plus a raid card and Xfi.

On inspection, I believe it would be possible to customise the heatpipe to allow the second molex to connect. Whether I'm up to the task is another matter !

Cheers,

Yes I would have to agree on all counts. The one molex should be enough for what you are running and the customisation of the heatpipe heatsink fins should be a simple operation if you decide to go ahead. I have the same cooler on my board the UD7 and looking at it there is no big problem at all. It would void the warranty on the cooler but that isn't part of the motherboard so no big worry.  ;D
