This graphics card booster cable provides additional power from the internal power ports to graphics cards which require more power than the standard PCIe slot provides. Perfect for adding a 2nd video card to your Mac Pro!

Hey all, I got a 2*Quadcore 3.2ghz 2008 Mac Pro (for free!) recently and I've done a few upgrades to it. I gave it 12GB RAM, a SSD and a few USB 3.0 ports.

Next up is a Graphics Card. There's no compatibility list online that I can find and googling hasn't helped me a whole pile to be honest. I'm struggling to find people conclusively saying 'Yes.

The Nvidia blah blah 100% works.' I'm looking to get a fairly decent card because it'll be used for 3D modelling / visualisation. I'm looking at an or an. They're pretty affordable and there's a few available on a local classifieds site here so it'd be nice if they worked. From what I'm reading Nvidia cards draw less power than ATI so I should go in that direction anyway?

Is that correct? Will these work or will I have to go for a slightly older card than these?

Would you be able to recommend me some cards so I can have a google and do a bit more research? I'm aware that if I used an unflashed card I won't get a boot screen but it's ok. I'll keep the old GFX card to hand if I do need it. Edit: I'm running El Capitan if that makes a difference:) • • • • •.

Get a gpu with no more than 2 6 pin power connectors. A 780 will not work unless you use a secondary power supply which is iffy. A 970 will work as long as it is the 170W version of the card and not the 200W version. You will not see anything when booting until the login appears. Sometimes when waking from sleep the screen will be black. My passport for mac instructions. Go back to sleep and wake it up again.

If that does not work restart the computer. If you want my personal advice though, pick up a cheap gpu like a 950 or 750 ti and wait until pascal launches in a couple monthes and upgrade to a better gpu then. Pascal is claimed to offer the biggest performace increase in 1 generation of gpus ever.

First: you already know, but needs to be said every time because so many people freak out. You will not have a boot screen.

Second: You probably won't be able to see anything until you have the drivers installed and activated. There's a number of ways around this, the easiest is to turn on screen sharing, connect from another computer, install drivers, reboot, and it should work. If you don't have another computer, or you can't remote in due to something else (boot issue preventing you from getting to the non-visible desktop for example) you may need more power to run your mac native card and the PC card at the same time. You can use a power supply from another computer but it's scary. If your current card only requires 1 6pin and your new card only requires 1 6pin then you are fine and can just run both without any voodoo. OK, all of that out of the way.

I have a 670, and a 970. I have run both on a mac pro 1,1 and 5,1. Both work fine. The 670 does not require nvidia drivers to display the desktop as Apple includes drivers for that chipset. The 7xx series might be supported similarly, which makes setup and trouble shooting a lot easier obviously. Superhero mmorpg games for mac download. The 9xx series requires nvidia's drivers to show anything at all.

In either case you will get MUCH better performance with nvidias drivers so use them even if you don't have to. Any card will work, you don't need anything special. However if you have any 8 pin connectors, or more than 2x6pin connectors, you will have to get power from somewhere since the motherboard only provides 2x6pin. IMO it's worth making sure your card is 2x6pin or 1x6pin so you don't need to try to pull power from some sata ports, or get a secondary PSU, etc. The hassle isn't worth it when there are plenty of options. I would personally recommend a card with a full shroud because it won't vent heat into the rest of the system. The MacPro has nicely designed airflow, you can either take advantage of that with a shroud.
