OWC Teardown of the 2019 Mac Pro

When you leave your new mac pro in the wrong part of town

Have you ever wanted to gut a 2019 Mac Pro to see what’s inside? Yes, it’s a risky proposition. But, now you don’t have to because our OWC friends Tom and Brady have done it for you! Watch as they take apart a 3.3 GHz, 12-core 2019 Mac Pro with an Afterburner card.

Just make sure you don’t leave it in the wrong part of town.

Note: If you’re worried that the 8, 12 and 16-core Mac Pros memory limits are too low for you, check out how OWC has confirmed that you can upgrade these machines to 1 TB of memory, saving you up to 65% over factory installed options!

2019 Mac Pro Teardown – The Parts


  • Could someone please verify that the extra four power headers on the main board (those intended to power video and other PCIe) are truly proprietary? The Belkin AUX Power cable images on the Apple Store aren’t super clear, but they look like standard eight pin locking connectors to me.
    it irks me to pay $67 for $10 worth of everyday cables (notwithstanding most will go unused in a drawer).
    Plenty of discussion that the SATA power header is a custom ten pin part (though it only uses eight contacts ( 4 by 4), and you have to buy an incredibly overpriced bracket and super noisy drive in a size you probably don’t want, just to obtain the $5 custom cable for pre-regulated SATA power.

  • Very nice. I’m pretty sure iFixit didn’t go this far. That bare cage is cool looking too. My question here is this: is the CPU’s IHS custom for the Mac Pro, or do all tray models look like that? If it isn’t a custom IHS, that would at least leave open the possibility of future upgrades by the end user.

    I do wonder how much latency the PLX multiplexer switch adds. I know previous motherboards on the PC side that used PLX switches to “gain” PCIe lanes introduced unwanted latency, especially if used for GPUs.

    I’m actually glad Apple took some design cues from Noctua with the heatsink’s heat pipe and fin array. That looks exactly like something Noctua would make if they made Mac Pro heatsinks.
