you did not read the review.

you are using the hdd cables not the pcie cables the review clearly states to use the pcie cables not the hdd/sata/molex garbage.

only use pcie cables on the risers. each card gets a feed from the pcie cable on the riser. do not deal with the shit cables

Sorry, I didn't saw the PCI on the risers!
I buy 6 risers for 66 euros, I should received them 26 Jan, will test them for a week and if it's great I will send you tip

So you are saying that your molex connector got burnt ( or your PCI connector got burnt?)
Can you take a better picture to show what is broken and where is it burnt?

Which motherboard are you using? If it is H81 (as you are having 6 RX480s per mobo so my guess is that it is H81btc pro) then do not power your motherboard through molex power connectors. If you power that molex on motherboard it will burn due to some weird problem.

I use a lot of those boards and there is nothing wrong in powering those with a simple sata connector and PCIe to the USB riser. Make sure that you are using only one sata port per USB riser. DO NOT use sata extender (used to power multiple HDDs) to connect multiple USB risers. If needed use Molex to sata converter but dont put too many connections on one line.

...Waiting for the pictures ...

I use EVGA 550W to power mobo and sub risers (all 6 of them) and
http://www.ebay.com/itm/94-Platinum-1200-Watt-Power-Supply-Kit-for-GPU-Open-Rig-Mining-Ethereum-ZEC-/371643723687 to power all my graphics cards through PCI-express slots.
Its a platinum rated PSU so wastage of electricity is wayy too less.

Take a look :

The last one has burn
I use 2 riser on one cable (4xSATA).

I'm using H81 pro btc, you guess well
Are you sure I need to not power my motherboard with 2 molex ?
How many riser can I connect on 1 cable with 4xSATA ?

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
