This is the one I'm talking about:

As you can see it has a small 4 pin power connector. You don't have to use it as the riser itself is powered.
The one your looking at is probably a good choice.
I guess I can get this "adapter/riser thing" on e-bay right?
It's much better to get this adapter. you can run upto 4 devices from this one. I am using one with 4 cards plugged in. no additional power required by the adapter either. Just ensure you get the VER 002.

I had an incident of that m.2 pcie adapter burnt out. Luckily didn't damage any components on the board. The pins below can get bent and short out.
This works 100%??
I am using 2 cards. All 4 ports work for me on 2 separate Z270 motherboards
Imo it's definitely worth trying out yourself for 14 bucks odd.
So you can potentially run 9 GPU's with this adapter plus the other 5 slots?
Is anyone running these right now can say how they're working?
Thanks heavyarms
