I'm not a scientist!
please share the TPD of this card, for what I know:- PCIe slot = max 75W
- both mobo 6 pin power cable conn = max 2x 75W = max 150W
Combined = 75 + 150 = 225W
Is that the dual MDP GTX760?
We have done an EFI version, I even sent 2 to Barefeats when he was doing dual GPU testing.
There is no way for a 760 to need more power than a 680. (Same chip but running in smaller card) so no power worries.
Confusing thing for us is that sometimes GPUS have 8 pin connector because they need it and sometimes it's to look impressive. Sort of like a 6 cylinder car with large dual or quad exhaust, when a single would do.

Seriously, this can easily be found with minimal effort on Google.
If I google it all the info I get is Windows related. Beside that I see that there is the fan and fanless version... So sorry if I am missing something but I'd appreciate if a user of the GT 610 fanless can confirm that is working properly on mac pros 5,1.
In the Asus website it specified 225w power consumption http://www.asus.com/ph/Graphics_Cards/GTX760DC2OC2GD5/specifications/
Though as much as possible I prefer having PC cards modified by MVC to be sure. Better to spend a little more and ensure the card fits into the Mac Pro's power supply envelope.
Please correct me if I'm thinking bad
I'm afraid this is not good!
The Asus website specifies ADDITIONAL 225W power consumption supplied by the 2 6 pin to 1 8 pin y-split cable and NOT TPD! So IIRC it wil draw 125W per 6 pin from the mobo....
Please correct me if I'm thinking bad, but that will likely KILL his Mac Pro's Power Plant over the two 6 pin connectors and/or PCIe slot? Very confusing indeed.

^^^^The threat of a GPU drawing too much power on a Mac Pro, is not really the PS, but the traces on the MOBO. With that being said, I have a MVC modified Gigabyte OC GTX 780 in my 5,1. The card came with 2 8 pin connectors and MVC shorted out two of the pins on each plug. The GPU is over a year old and has been running fine since installation. The toughest stress I have done is Unigine Heaven Extreme at 2560 X 1440 resolution. This took gobs of power, my UPS shows power draw, but the Mac handled it everything fine.

Where did you find the word "ADDITIONAL"
There is a section that says "Power Consumption" which they enumerate as "up to 225W1 additional 8 pin PCIe power required"
So, 75 Watts from slot and 150 watts from 8 pin for a grand total of.......225 Watts.
Please read the OP of this thread. That's kind of the whole point of this large FAQ thread that is stickied at the top of the forum, it's even right there in the thread title.
TL;DR - PC cards should work right out of the box.
Thank you for this thread!
Just wanted to post that I had success installing a GTX 760 2GB in a Mid 2010 Mac Pro without a hitch thanks to the info here. I used a 6pin to 6pin cable and a 6pin to 8pin adapter and it works fine except I no longer have a temp readout for PCI card which I did before when the stock HD 5770 was in it. I was wondering if there was a way to get the temp reading back?

Thanks MVC! Okay, so I misread the info's at Asus website, my bad.
My misreading started at: "up to 225W1 additional..." I have to read more careful.Cheers
My apologies for being redundant, but...anyone could help me to install Mavericks? p.s. Gainward GT640 works out of box with 10.7.5 on MacPro 1,1 really smoothly although it's a Kepler card!
Hi to all and sorry for my bad english. I'm a newbie in Apple world.
I want to install Mavericks on my sister's MacPro 1,1 and the original GT7300 is broken. I've bought a Gainward GT640 from Amazon that will arrive tommorow. At the moment I use an old Geforce 9600 GT of my friend. It boots on 10.7.5 (boot screen doesn't work obviously) but i don't know how I'll be able to install Mavericks if i'll not able to choose the boot device! I don't have another Mac machine so i can't follow the procedure of install the OS on external hard disk.. I've heard about an alternative bootloader called Chameleon that could help me. Has anyone of you tried it in a similar situation?
Or......is it possible to select the boot device before restart the Mac? I do something similar on my Linux desktop by using a script for GRUB.
Thanks in advance and i hope to resolve the problem ASAP
Can a PC Quadro 4000 for Lenovo can be installed into 5.1 mid2010 MacPro?
I bought a PC Quadro 4000 for a Lenovo desktop secondhand hoping to install it into 5.1 mid2010 MacPro? I assume no special chip or flashing modification are necessary for my situation.
But it has extra bits and pieces, some attacked to it, that I really don't know what they are and if they need to be removed in order to install this into my MacPro.
I am attaching a photo of the card, the separate fan and some extra bracket that came with it. I hope someone can explain how to install it.
I have already downloaded and installed the driver for the Mavericks OS just in case that was necessary.
I don't have an Apple Mac Pro video card power cable like this :
http://eshop.macsales.com/item/Apple/9227128/
...so I guess I have to buy one of those to even try this.
What is the worst that could happen? If I install the card and it doesn't work, can I just put the original ATI Radeon card back in and retort the Mac?
Any advice or help would be immensely appreciated. Thanks in advance.

Though it might be cheap, AVOID the gt610 at all costs! It will work, but it's crap. A bit of advice someone gave here: "avoid the x10-x30 range like SARS" You can get a decent 650 for likely under a hundred bucks.
As usual OWCs prices for a used cable are quite high IMO. Here's a brand new cable:
http://www.ebay.com/itm/PCI-E-Mac-P...n_Power_Cables_Connectors&hash=item43cb46b438
Your Mac Pro came with an AMD 5770, and that utilizes a 6 pin power cable that should work with the K4000.
For that card to fit, that rear piece will ned to be removed. It should work, Nvidia's Web Drivers support the K4000. However, of course, no boot screen.

MSI NVIDIA GeForce GTX 680 Power Edition 2GB into Mac Pro 1.1
Hi all,
Not sure if I'm posting in the right place so if not feel free to move this post.
I have MSI NVIDIA GeForce GTX 680 Power Edition (2GB) which I have tried to put in a Mac Pro 1.1.
As recommended by others on this forum, I have used two 6pin PCIe cables, plugged into the 8pin connectors on the graphic card.
However, when I turn the machine on, the fans spin for a while, then after a while a message pops up.
"Please power down the machine and connect the PCIe cables".
I have the two cables connected. The card is seated correctly.
I removed a USB3 card, and the original 7300GT graphics card, so that the GTX680 is the only card installed.
I have tried the card in slot 2 and 3.
Has anybody had this problem. I was under the impression the GTX680 worked fine with the 6 pin cables? Or is this a problem with the MSI version of the card, as it is slightly over clocked?
Thanks for any help.

Yeah, 680s are funny. Some will run fine with 6 in 8 socket, looks like you found one that won't.
A standard 6 to 8 adapter should trick the sense pin.
Did you get one with card? The ones they ship only work one way. (If it has yellow, black, and brown wires, use side without brown)
Can a PC Quadro 4000 for Lenovo can be installed into 5.1 mid2010 MacPro?
Thanks for the reply, Lou. Very much appreciated. When you say 'the rear piece has to be removed' I assume you mean the black extension in pic 1, not the heatsink(?) in pic 2, yes?
One other question which is really worrying me is if I install the card and boot the Mac and it doesn't work, what will happen and how do I get out of the situation? I simply can turn off the Mac and put the original AMD 5770 card back in? Mightn't be hard at all, I just can't afford to screw up my Mac for any period of time. Thanks in advance for your help.

Yes, one 6 to 8 pin cable did come with it as it happens, yes the end which fits into the motherboard doesn't look like it will fit. Do I need to cut the 8-pin plug off it and graft it onto the 6-pin cable ?
----------
Or would one of these 6- 8 pin adapters work ? To plug my existing cable in to?
http://www.ebay.co.uk/itm/6-pin-to-...apter-graphics-card-power-cable-/191149463647
You'll want a MP power cable
The card will work just fine, in fact you will have 2 @ DP ports while Mac one only had 1.
Don't expect stunning performance, it is basically a GTX450/460 with extra Double Precision ability and nicer ports.
Anything is an upgrade on the stock 7300GT. That just keeps on throwing up warnings in Photoshop of not enough VRAM, and well, using it for Maverics / Yosemite is never going to work I hear.
