I have bad experience using M2 adapters - tried to power them and it basically smoked and burnt the 4-pin adapter that was provided - that 4-pin molex adapter is of very low quality.

Without using the 4-pin molex, I could get a 1070 working so I guess single 6-pin PCIE powered GPUs should be safer to use with this adapter without power (ie drawing power from board).

Anyways, I have 12, 13 PCI slot mobos TB250 and H110 - so I will use those for high density rigs -- I don't need to use the M2 adapter.

I think better use M2 as a storage link as per designed rather than using it for PCIE x1 - many things can go wrong.

Phil - the office rang me this evening about a box from Shenzen arrived in the morning. I got some 4GB mSATA RAMS too - Pandaminer stlye. Will do the testing this week and send you a unit. Check YM.
