Edit: Solved. I swapped a Silverstone SX700-LPT into the Mantiz Venus and had issues getting it to turn on. After troubleshooting I tried the Corsair SF600, which worked perfectly. Seems it was an issue with how the Silverstone PSU deals with turning on/off.

Power cables not completely plugged in to the GPU is a possibility - but usually this would cause shorting and safely shut down the enclosure (for Corsair PSUs, you would hear a click when something like this happens). Reseat the GPU. What Vega 64 is this? Finally, try the old PSU to ensure that at least the previous-working configuration is still functional. If not, there may be some damage to the board/PCIe slot for GPU.

Well, I put the original PSU back in and it worked OK.
I know the new PSU works, though - it boots on the old system i took it from.

Could it be that the PSU isn't compatible with the eGPU in some way?

Very surprising. All I can guess is that when you changed PSUs last time maybe some connection was lose. Only option is to try again :p sorry for not being helpful.

Well, I rebuilt it again with the new PSU, and it’s working. I have no idea what could have been wrong last time - all the connections were in place. 

Well, here’s hoping it stays this way. 700W should be enough to keep the Vega64 happy.

Same thing happened to me - I have the same enclosure, power supply and video card!. What I found out is that the cables in the Silverstone PSU are a bit too big to fit properly in the Mantiz sockets. First time I did not get it to boot properly, reseated everything and bam, it worked the second time around. Unless you plan to toss your eGPU around, it should stay put!

Current build: 2017 15" MacBook Pro + Mantiz Venus MZ-02 + Silverstone SX700-LPT (750W Peak) + Noctua NF-A14 + Gigabyte GeForce GTX 1070 G1 Gaming 8G (rev. 1.0)
Replaced parts: Sapphire Radeon RX 580 Nitro+; Sapphire Radeon RX Vega 64 (Reference model)

Bumping - does anyone have an idea why this SFX-700LPT would not work (or only work sometimes) with the Mantiz Venus?

It works 100% directly in the PC, and the Mantiz Venus works 100% with the stock power supply - so the parts are all good.

Are you using the same cables for both the PC and the PSU? I have even swapped to a GTX 1070 and it works reliably. If you have confirmed that the PSU works, I can only suspect on the cables, or the Mantiz board
