  GTX 485 with Quadro 4000

  Posted by Alejandro Arriaga on January 28, 2011 at 7:56 am

  Hi!
  My name is Alejandro, from Mexico City…

  In the next 2 weeks I’m getting a new mac pro.

  I want to install the gtx 285 and the quadro 4000,

  those cards together need 3 auxiliary power connections

  and the mac only has 2.

  How can I get 3 power connections???

  thanks, appreciate it!!!

  You’ll have to pull power from where you put your second super drive there with an adapter cable. Even then it can cause instability, but you can always try. You’re better off getting a gt 120 for your gui, or two quadros.

  After checking the actual wattages of the cards, I just bought a $10 PCI-e Y-splitter from NewEgg to squeeze both a GTX 285 and my old ATI 3870 in my 2008 Mac Pro.

  My experience of the GT120 was awful. Although OK for Resolve, the overall Mac GUI was jumpy and laggy, Photoshop lagged, etc. Obviously, if you have a dedicated machine, then maybe that’s a risk you don’t want to take, but nothing bad has happened yet!

  I may also return the GT120 for an ATI 5770, which has the same power draw than the older 3870 for twice the power (I still use Color on the machine while I’m learning Resolve).

  You, but you wont have space.
  At least I dont, with all the other stuff in it.
  But if anyone could point me to a proper one slot solution to get rid of the Gt120, I would be happy.
  No, i am not thinking about get the 4000 yet 🙂

  Ah, yes. Didn’t realize the 5770 was a 2-slot card. The 3870 is single, though, and seems to be working well.
