Hi, I've been having issues with my 2 rigs (12xRX480, 2x Lepa G1600w)(have driver 16.11.3) Some of my modular cable from PSU are burning when they are connected to my powered risers (see photo) http://hpics.li/8f15c02This happens to me 3 times and it's always the same connector who burn Should I use pci to molex converter to power my risers? Could anyone help me? Can pay 0.1 zec if anyone give me a great solution

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.

Seasonic X series, SilverStone (any of their Gold models), EVGA G2 series for me.
Enermax has been iffy on the few I've had, one died outright another is flaky 3'd seems to be very solid (the solid one is one of their Platinum models other two were lower-end).
Corsair varies a LOT, seems to depend on the specific model and who's MAKING that model for them and I gave up trying to keep track on them years ago.
PC Power and Cooling USED to be good when they made their own, but they've gone to junk since OCZ bought them out.

The LEPA 1600w is a fine PSU, nothing wrong with it. http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=283OP, you simply piulled too much power through that 12v pin. Don't go over ~70w on a molex or sata chain. Any modular PSU will melt a connector if you pull too much power through it.

Here many miners were stupid to buy "Lepa" (most bought 1000w model) some 40%+ dies in first month, cables and connectors are also garbage

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

Connect every power connector that are @ your disposal (riser + gpu + mobo), it's better to balance the load between multiple line of power for smoother output from your PSU and enhanced stability, it will also protect your hardware from overload resulting in burned out connectors or worse hardware, not that it's mandatory, it's just good practice imho, better safe than sorry

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

This thread has taken on a life of its own. The OP showed an image of the connector at the PSU. Assuming that is where the damage is occuring the problem is either a bad connector or too much power draw on that line. Given it has been observed on 2 different PSUs and "some" cables a bad connector is unlikely. Reduce the load on the burning lines. If your PSU is not overloaded it's just a matter of balance, as someone else mentioned.
Edit: If your PSU has 2 SATA lines and you're using one for your peripherals and one for your risers, split them up. Put one GPU and one peripheral on each line.
