There are probably some configurations that need the aux power kit but, I'm one of those people that bought it and didn't end up needing it (HDX2 in MacPro7,1). Someone else can better chime in.



Your constraints are: how many slots your graphics card takes up, needing to put the HDX cards adjacent to each other (for the TDM SATA cables), and needing to put the Sonnet SSD card in a x16 slot.

So, if you have a W5700X for example, then the GPU would take up slots 1 and 2; SSD card in slot 3 (x16); HDX cards in slots 4-6 or 5-7; I/O card in slot 8. Slots 5-7 will eliminate the requirement for a longer TDM cable, so I would recommend that.
Thanks so much Luke - hugely helpful.

My graphics card will likely be the (1 step up from stock) Radeon Pro W5500X with 8GB of GDDR6 memory

I believe it is a "half-height MPX Module design fits in either MPX bay"

I'd probably stick with the same order as suggested earlier, but you could also try: W5500X in slot 1, HDX cards in slots 2-4, SSD in slot 5. The only catch here is that you will need a longer SATA III cable instead of the stock TDM cables. Avid suggest a 10" (or longer) cable but this is way longer than required, and any cable that bridges the gap should be fine.

Of you plan to use Thunderbolt for external storage or other external devices, then the W5700x is a good idea. It adds thunderbolt busses to separate graphic bandwidth from your other devices.

But if you’re not planning on having much for external devices and screens, then never mind.

That's a good point. IIRC, with the RX580 or W5500X there are two Thunderbolt busses (front panel and I/O card). The dual-width GPUs add an extra two. (Each bus has two ports, and all Thunderbolt busses are assigned to PCIe Pool B.)

Thanks - this wasnt even on my radar.... too darned complicated!

I'll have one 1080p HDMI monitor, and then 2 other monitors, but none of them 4k.

Currently in my 2012 cheese grater I'm using a ATI Radeon HD 5770 1024 MB and it does all this just fine.. so hoping i would be fine with the video card I mentioned above.... ?

thanks.
