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
There is some mix in the picture, but i found picture with small heatsink using one PCI-e power connectors

Actually each wires on PCI-e power connectors can stand up to 10 A. So total is 30 X 12 V = 360W

not to question your wisdom Zich

but doesn`t that deppend on how many amps your psu can give?
i`ll explain the situation , i bought this psu from a college from work for €15 it a recom pe-m500 500 watt (new in a box never used) , atm it is only powering 1 hex16a2 and 3 case fans.
It has 2 rails of 20 amps, it has some molex & sata connectors etc.. & 1x pci-e 6+2 connector , what i was wondering if i could connect an hex8a1 (4 chips) to this psu without being afraid than 1 day i come home and find my computer room on fire
specs of psu: what do you think ? i think it wouldn`t be a problem to connect a hex8a1 4 chip
