Hi i just got the 8pin pcie input to two 6pin pcie for miners , the cable gets full power from the 8pin psu wires Smiley http://www.icemodz.com/webshop/#!/~/product/category=9873175&id=39683119


I would monitor the cable a little bit on heat.  Depending on power and quality that could melt.   I have seen it done during GPU day's when i used one.  Yes it was included with a low price psu and was cheap.

I have a bunch of these and they work great. I have no idea where I got them though.  Undecided

Give them to me now!

Dunno how much he would charge, but Cablez might make you some. He specializes in wiring harnesses for FPGAs.



I couldn't justify paying his markup and a shipping charge.  That's the whole reason I convert my own PCI-E extenders to powered, and short the detect pin on them.  $3 in parts and 15 minutes of my time beats paying $20 for one of his cables and then having to short the detect pin myself anyway.

You can find an adapter, but the one I ordered from Amazon was 20 gauge crap.

I haven't been able to find one.  Even if I did, I wouldn't use any 20 gauge crap.  I'm thinking about maybe building my own using 16 gauge wire.

I have been able to find 8-pin Y splitters that look rugged enough.  Then from there go to 6 pin with a 8 to 6 adapter.  However, that would cost about $20 in cables for each 8 pin I wanted to split up, and I have 8 of them.  That's $160 total, not really sure I want to go that route, not only due to price but also because more connections equals more possible points of failure.

I may just go with some 6 pin Y splitters since I'm running a Seasonic PSU, and I know their wiring is up to par.

If the power rating for a 8 pin power connecter is 150W, and a 6 pin is 75W, shouldn't it be possible to power a dual 6 pin graphics card off of one 8 pin power cable that was split into two 6 pin connectors?

If not, how come?

If so, why can't I find a adapter cable for this?

I had wondered this myself until I found that that the 6-pin is capable of 150W.  The additional 2 are "dummy" pins.
