I recommend reading this whole guide first before starting, don’t just follow along before you know the whole process. All images can be enlarged by clicking on them. I made this a step-by-step that covers everything, even stuff you probably already know. Having the Mac laying down makes things much much easier.
MAC PRO POWER SUPPLY UPGRADE MOD
Let’s dive right in! I have tried this mod with the Mac standing up and with the Mac laying flat on a table. The screw bits, flexible extension and screwdriver I used are all in this iFixit toolkit. I’ve read that the Posi-Tap is a popular choice for this mod as well. I’m sure there are other options for tools and taps, these are simply the ones I decided to go with. Maybe he first wrote about the mod on his blog or something (I can’t find it if he did) thus the name “Pixla’s Mod” which turned into “Pixlas Mod” because people are too lazy to type an ‘ I guess. The guy that first came up with the idea for this mod, named Andree, has a website, pixla.ch. – PCI fan (optional but will make the job much easier)
I also put a Kit together which can be found here:Īs an Amazon Associate, I earn from qualifying purchases.Ĭomponents that have to be removed (in order): – Compressed air (if you want to give your Mac a good cleaning while you’re at it) (Ships from Hong Kong, allows for cable length and color selections.)

MAC PRO POWER SUPPLY UPGRADE UPDATE
Latest update added on September 8th, 2020. At the very least, I now have the latest version of macOS running on the box.Updates and new relevant information is listed at the very bottom of this article. So, my attempt at bringing new life into an old Mac Pro wasn't a complete failure. In fact, I've decided to order an eGPU (likely the AKiTio) so that I can pair it up with a modern MacBook Pro and remove the issues of CPU bottlenecks and power delivery. This is not to say that upgrading your GPU on other Mac hardware is a lost cause. The lack of proper power cables and the weak Xeon CPUs on this Mac Pro make upgrading the GPU nearly pointless, since gaming with such a highly variable frame rate would prove maddening.

Even though the 2009 Mac Pro is capable of running macOS Sierra (as proven by me hacking it onto the system), there are myriad other aspects that also have to be up to spec for full functionality. There is a reason why Apple decided not support some older hardware from being able to be upgraded to newer OS revisions. Hell no! Even though I got a new GPU to work in the Mac Pro, the other components being so weak make this a moot point. It would have been worse with the 1080 ti. This means that the Xeon CPUs from the Mac Pro are far too weak to properly supply data to the RX 480 GPU. Although the RX 480 has some much better frame rates, the variation of FPS was very high. I took one of the RX 480's and placed it into the Mac Pro as per a tutorial.Īs you can see, there are some very strange results here. I have a second gaming PC on which I run an Oculus Rift running two MSI Rumor RX 480 4GB. So instead of going "big" with the NVIDIA GPU, I pivoted to go "medium" with an AMD RX 480. This GPU is also not supported on macOS, but at this point I figured I'd try to exhaust all of my options.
MAC PRO POWER SUPPLY UPGRADE 1080P
The AMD RX 480 is a recent generation mid-range GPU that is good for 1080p gaming and entry-level VR. After a bit more googling, I came across an excellent tutorial on installing an AMD RX 480. I made further google searches and there were a few things I could try, but, frankly, I think that this Mac Pro is just too old to properly power the 1080 ti. I powered off the Mac Pro and put the old GPU back in and it booted up without issue. The Mac Pro powered on, but it didn't make the familiar Mac "bing" on start up. I plugged in the two 6-pin power cables anyway and closed the side panel and fired up the Mac Pro and I waited for the login screen… and waited. No matter! It's only missing a measly 25W. Each 6-pin power cable provides 75W plus the PCI connector bus provides another 75W for a total of 225W. Plug in the 6-pin and the 8-pin power cables.Įxcept the 2009 Mac Pro doesn't have an 8-pin power cable.Unscrew the expansion card retainer plate. Disconnect the 6-pin power cable from the old GPU.I shut down the Mac Pro and proceeded with the hardware installation.
MAC PRO POWER SUPPLY UPGRADE INSTALL
With my new macOS Sierra freshly installed, I was able to successfully install the NVIDIA beta drivers without issue.
