What i have done is:
1 PCIE 6 PIN to -> 3 x molex (GND, +12V) , rest, mean 3.3V and secound GND is powered from molex/SATA.
Work great for 3-4 mounths now.

Are you talking about something like this ?
/sRkl3D][Suspicious link removed]/sRkl3D/CA4mPr]https://[Suspicious link removed]/CA4mPrSo I will no use those cable with 4 SATA
But I found the two others cables who had burn and they have 4 molex ..

And RX 480 was not overclocked
Do not ever use SATA hdd extender for riser. Use any other PCI-e connector. Molex, standard PCI-e to SATA (in your case SATA to PCI-e) will be fine.
DO NOT EVER POWER molex connectors on the H81 btc mobo. It will create a feedback loop and either fry your motherboard or your sata cables) .. In you case you have already fried sata cables.
LEPA PSU us good as long as it does not die. As someone suggested above; use PCI-e 6 pin splitter and connect one end to PSU and other (split end) to USB riser and graphics card. once again.. DO NOT power molex connectors on H81btc mobo it will fry your mobo.
Let me know when it works (I am sure that it is going to work).. I will send you my ZEC address once you let me know that its working. Cheers my miner bud
I will try without molex on the h81 ! Hope it will not fry my motherboard
Where can I find those "PCI-e 6 pin splitter" ?
Thanks a lot !
I go sleep now. Tomorow morning i can go to mining room and make photo for you. I was custom made this cables. If you use old (not USB) risers i have one type 6pin -> 3x molex (only 12V), with new USB risers i use same but additional add 3.3V and GND from SATA connector. At risers most use line is +12V (yellow cable that you have burned).
And you must always know. Less Voltage = more Amps. More Voltage = less Amps. Amps burning your cables not Voltage. But this is only theroy.
