Is this going to work out of The box. ??

I am using a Zotac GTX 650 in a 2009 Mac Pro. It works out of box with Mavericks.

I do not have a GT 120 installed, however. Judging by what I've read of other's experiences, the GT 120 should work alongside the 650.

GTX 650 requires only 1 power cable. Do you have the necessary 6-pin power cable?

Is that a stock card (not flashed) ?

Do you get Boot Screens ??

My GTX 650 is stock, not flashed.

No Boot screens.

I have never run this card alongside an Apple OEM graphics card. Do you know if the OP can use his with the GT 120? I am guessing the Apple card will provide the boot screen if a display is attached.

And I am assuming the OP's card is not flashed.

I developed this "boilerplate" to list all the footnotes of various setups. I welcome suggestions for refinement:

RE: Mac Pro silver tower (2006-2012) Replacement Graphics cards

1) Apple brand cards,

2) "sold in the Apple store" cards, and

3) "Mac Edition" cards ...

... show all the screens, including Boot up screens, Safe Mode, Installer, Recovery, debug screens, and Alt/Option boot screens. At this writing, these choices include:

1) Apple brand cards:

• Apple-firmware 5770, about US$250** works near full speed in every model Mac Pro, Drivers in 10.6.5. (This card has just been discontinued and is no longer available from Apple dealers. There may be some new, old stock still available at resellers)

• Apple-firmware 5870, about US$450

2) "sold in the Apple store" cards

• NVIDIA Quadro 4000 Fermi, about US$1200

• NVIDIA Quadro K5000 Kepler, about US$2500

3) "Mac Edition" cards -- REQUIRE 10.8.3 or later:

• SAPPHIRE HD 7950 3GB GDDR5 MAC Edition, about US$480** Vendor recommends Mac Pro 4,1

• EVGA GTX 680 Mac Edition, about US$600

The cards above require no more than the provided two 6-pin aux power connectors provided in the Mac Pro through 2012 model. Aux cables may not be provided for third-party cards, but are readily available.

--------

If you are Meet ALL of these:

• running 10.8.3 or later AND

• don't care about "no boot screens" etc AND

• can re-wire or otherwise "work out" the power cabling, THEN:

You can use many more cards, even most "PC-only cards".

--------

One more thing--

Flashed PC cards: There are a good many EFI flashed cards that offer boot screens and behave like official cards. "for more information about using and flashing non-Apple cards, please check out the various sites like Netkas (and others) that focus on and discuss what is known and available. (Not supported or endorsed by Apple.)"

.

Do you know if the OP can use his with the GT 120? I am guessing the Apple card will provide the boot screen if a display is attached.

It should supply the Boot screens if it is the Primary display.

There was a problem in some versions of 10.8 that caused kernel panics when multiple NVIDIA cards were installed. My recollection is that this has been fixed in 10.9.1 and later.

Hi Fransfromnld,

Does your GT 120 card work with your GTX 650?

thanks
