Quadro 4000 and ATI 5770 on a Mac Pro

[Scott Reynolds]

I’m glad it’s running well. You’re marginally over the power specs for the machine. The 5,1 can support a max of 300W for PCIe, the 5870 runs 188W and the 4800 runs 150W. I hope you don’t have Apple Care, they might invalidate your coverage based on your setup. Thanks for your answer on the power connectors. I hope your rig continues to give you no problems.

Hello Scott,

Can you post a link where it say the max for the PCIe slots is 300w? I’ve looked on apples site and googled it and still could fine anything. I’m looking to upgrade my memory so power is a real concern. Thanks in advance.

I see it now on the apple site. hmmm… does this mean I’ve been lucky so far?
300W combined maximum for all PCI Express slots

I wonder how I can check to see how much power my Mac is using. I can’t find any counters that will tell me.

Currently I have:
16GB ram installed
4 hard drives (one is an SSD drive)
2 video cards

I guessing if I add memory the power is separate from the PCIe slots.

Hi Francois,

I am in the middle of setting up a Mac Pro 5.1 Mid 2010 I will receive next week and I saw your setup. I do have some questions about it and it would be great if you have some spare time to answer them.

Here I go:
– I thought a 5770 has a required width of 2 PCI slots, how is it possible that you have a q4000 on slot 2? Do you have some extension slots installed?
– Do you use a raid card on slot 4 or is your raid a tower which is connected through usb/thunderbolt?

Thanks again,
Regards,
Ralf

HI, R

I need to update my profile… 🙂 My setup currently for my Resolve suite looks like this:

MacPro 3.1 , 32Gig RAM
MacOs 10.8
Samsung SSD for system
Quadro4000 GUI
GTX 680 Cuda
CalDigit Raid 4x eSATA
BM DeckLink SDI

There is only 2x 6pin cables to power both cards. But the power-source for the Mac Pro has plenty of juice to handle it. So the solution I came up with is to put one cable in either card, and then to get an additional SATApower to 6pin adapter cable that goes into one (or two) of the empty drive bays to add additional power to the GTX680. I ran a monitoring app to make sure I’m not hitting the power source too hard but it did not even get close even with heavy nodes. NOTE: (* ADD disclaimer here: Should you decide to the same it’s completely at your own discretion… I’m not advocating you should follow my lead blindly. )
