@odin, yep the best cards, size wise, are those you listed and the ventus. All 2 x 8 pins too.

MacOS Catalina // Bootcamp Win10 2004 (Build 19041).

According to Nvidia, they are recommending a 750w PSU for the RTX 3090/3080, while recommending 650w for the RTX 3070. My Razer Core X is only rated for 650w (the Chroma version is rated for 700w). Are we Razer Core X owners going to have any issues powering the RTX 3080

That recommendation has a footnote that it's based a configuration with an Intel Core i9-10900K which has a 125W TDP which I believe is the all-core frequency power usage. I believe it can use 250W short term during PL2 boost. I would imagine a 500-600W PSU would be enough for the 3080 in an eGPU by itself.

 

As an aside, My Sonnet Breakaway Box 550 says it can handle a 375W continuous power requirement for the GPU, the 3080 spec is 320W. What's interesting is Sonnet says the Vega 64 and Radeon VII should use the Sonnet Breakaway 650 for the 375W continuous + 100W Peak that it provides. I'm guessing there's something about the Vega 64 and Radeon VII that can boost short term in this case.

It seems 500W+ might be OK, but it could be safe to wait for Razer to clarify it on their spec sheet.

EDIT: I asked Sonnet regarding the 550, got the following reply 

From our experience, a GPU TDP is average and not peak. We would need to test it to know. Meanwhile, here’s our statement...

The NVIDIA GeForce RTX 3070 uses a single 8-pin power connector and is compatible with all Sonnet Breakaway Boxes.
The NVIDIA GeForce RTX 3080 uses dual 8-pin power connectors and requires typically 320W, Until we can test this GPU, Sonnet recommends only the Breakaway Box 650 for the RTX 3080.
The NVIDIA GeForce RTX 3090 is a triple wide card and does not fit in any Breakaway Box.

Just to close the loop, Sonnet has updated their official GPU support PDF to include 3070, 3080 and 3090 cards and they only officially support the 3080 and 3090 in the Sonnet 650W. There's a couple of them that appear to be unsupported at all probably due to being 3-slot, extremely large 2-slot dimensions or requiring 3x8pin power.

Well, members on this site are definitely much more on top of things than Nvidia.

Nvidia couldn’t even identify a key product component (GDDR6x memory) as a heavily-constrained item - making their touted September 17 product launch date almost completely fictional. Big facepalm on Nvidia’s part. 

And “haha” to those sources of rumored 20GB and 16GB versions of 3080 and 3070 cards being held back until AMD’s RDNA 2 (aka Big Navi) product launch.

It’s pretty clear there won’t be 20GB and 16GB versions when Nvidia can’t even scrape together 10GB or 8GB from their supplier. But I suppose Nvidia can again claim they launched these new products, but - darn it, scalpers and bots bought all of them! 

That seems to be the company’s current strategy. 🙄

There were already posts in the last week saying the 3080 20G and 2070 16GB were "canceled" from AIB sources. It's funny that it was "canceled" when it was never even announced, but supposedly the AIB sources had hard info above and beyond rumor level that they were a product.

I'm just holding out to see reviews of the AMD cards from the typical reviewers I trust to see where I would like to land when the dust settles and card stock is again flowing freely. I can hold out and wait a couple months, this launch drama was fun to witness and discuss but in 6 months no one will care anymore it's not really that important. In a way I'm kind of glad it happened, I would have just gotten a 3080 and not waited to see what AMD is doing.

I'm pretty sure I will end up going 3080 though just for better RT performance and DLSS, but we shall see.

I was planning to get a 3070 but they delayed it and now I have an empty eGPU enclosure. Scouring craigslist constantly trying to find a good deal on something to hold me over until 3070 or big navi.
