Marto this 4 chip board is it gonna be powerd by 2 x pci-e or 1x pci-e ?
on the website it says "2(1) x 6 pin PCI-e power conectors @ 12 V" The latest picture show only one 6 pin PCI-e power connectors & it's already more than enough

my thought also, if i`m not mistaken 1 pci-e can do 150+watt that should be enough, but the pictures was a little confusing, both models 260GH & 130GH show the same pictures on the website.
but thanks Zich for answering my question
If it's half the power range on my Hex8A1-260GH's they'll be somewhere between 182-204W @ 130GH! (unless Bitmine revised A1 the chips)
Which is no more efficient than the Hex16B GH/W but is about 3x cheaper /GH.
But don't worry 6-Pin PCI-E can do way more than 75W, at least mine can on 18AWG rated wires.
