so i got this new grapics card and it looks amazing reminds me back of the huge cards i had in the past like 7970
now i got an issue. my current psu only got 2x 6 pin pci-e power cables and im wondering of thats the reason why the system wont boot cus the card got 2x 8
orginaly the hp z800 work system comes with 6 to 8 pin addapters i can find them online for a 100 usd per piece orginales ones. but i bought some cheap alternatives ;)
so im wondering if that would fix my issue if it realy needs 2x 8 pin connectors

Assuming you bought it used, there could be some powerplay mods in place for maximizing mining but causes 3d stuff to be unstable.

As long as your PSU has enough wattage you should be fine. Look at the diagram, the extra 2 pins are ground and sense. Sense are for power regulation, not power delivery.

is that not missing a +12v connection though according to the official spec? I mean I know I have heard this before but surely why the need for a seperate 8pin when a 6pin can carry the same kind of power?

Indeed, there's a reason for those extra lines, overloading a 6pin connection might be fine but it could trigger the OCP protection in the PSU.

so would 2x 6 pin work on 2x 8 pin connection?
