OpenGL 4.6 adds support for ingesting SPIR-V shaders to the core specification, guaranteeing that SPIR-V shaders will be widely supported by OpenGL implementations. SPIR-V is a Khronos-defined standard intermediate language for parallel compute and graphics, which enables content creators to simplify their shader authoring and management pipelines while providing significant source shading language flexibility. OpenGL 4.6 integrates the functionality of numerous ARB and EXT extensions created by Khronos members AMD, Intel, and NVIDIA into core, including the capability to ingest SPIR-V™ shaders.

J– SIGGRAPH 2017, Los Angeles, CA – The Khronos™ Group, an open consortium of leading hardware and software companies, announces from the SIGGRAPH 2017 Conference the immediate public availability of the OpenGL® 4.6 specification. The complete OpenGL 4.6 specifications can be found HERE

Now I understand what you are saying peak isn't all that matters. I think you need to check the power consumption metrics on both of these cards, and Vega, before making statements about it not being supported. Here HP don't list Vega in their list of support GPU's, but they do list both the R9 Fury X and AMD Radeon R9 290X. HP themselves also state upto 300W TPD GPU's are fine. Which you do not need to account for here. The only plausible reason you would think that a 500w PSU isn't sufficient is, if you're comparing it to building a PC, in which case you need power for the CPU, Mobo etc. Let alone the fact I also mine a lot of crypto as well.

You literally have no idea how much i tinker and mess around with hardware, given that it's actually part of my job to do so. Just because I rarely post here, doesn't mean that you're some how inherently right. I can prove to you that the Vega + Omen works fine with a 500w PSU, not mathematically, but empirically. It looks to me that several of you just like to be right for the sake of being right, or back your friends without any quantification behind some of the statements. Whilst the 64 did have some issues, the 54 never did. What extensively means is using different work loads for periods greater than 24 hours.

VEGA FRONTIER EDITION OPENGL 4.6 MAC
You can buy them off Amazon for cheap, just don't buy the Mac specific one, as it is using a different as explained I have actually tested extensively using a Vega 54 and Vega 64 using a 350W bronze rated PSU. To answer the OP - you need a 6-pin to 8-pin pci-e adapter. Stop telling people to waste their money on something you have zero experience testing. The vega 56 doesn't come close to the 500 watt limit. Works fine at stock, works fine over clocked, works fine in furmark, works fine gaming. You are just making stuff up my vega 56 works great in my omen egpu, absolutely no issues at all. They are not listed under supported hardware on AMD.com, nor any shipping eGFX box is approved for Vega64. Regarding Mantiz claims about Vega 64 - well, they are responsible for what they claim. You cannot compare HP box to Mantiz - different designs, different power supply. You are saying that so called "500W" PSU in Omen is enough, based on your extensive testing with various loads? I already explained few times on this forum what is difference between what you call "max draw" and peak currents. The fact it doesn't have the two 8 pin connectors is the only issue. The 500w PSU in the omen is enough, even if you factor in the draw for the USB ports and power delivery, and consider that it's a bronze rated PSU, it leaves you with enough headroom to run a 220W (or 200 with the bios switched into the read only bios) GPU. Over estimating how much is needed for the Vega 56.
