1  Bitcoin / Hardware / Re: [Setup & Troubleshoot] Bitmain AntMiner S1 180GH/S miner on: March 01, 2014, 06:27:32 PM

No, that doesn't sound like a converter cable. I want to convert my 8 pin CPU cable to 6 pin PCI-E, so I can plug it directly into the PCI-E connector on the board.


The extension cables are for CPU, where the 12V lines are on the same side as the clip and are yellow too, so the polarity was not wrong.
But when I stripped the cable at the end to go into the connector the wires inside looked really thin and flimsy. The markings on the cable says 18AWG and 80 degrees, but I have a 18AWG cable and the wire inside is really think compared to these.

Yeah, Do not use those.  You got ripped off  by One Hung Lo  mfg co.  I had bought some PCI extender cables, when I stripped it there were ONLY 5 TINY STRANDS of copper inside the wired labeled 18AWG! They  were more like 26AWG.  I took them back to microcenter and finally got my money back after making a stink of the safety hazard these posed.  Dont go cheap on extender cables, sadly, you cannot trust those off brands, they can burn your house down.   Maybe Cablez can make some for you?

I will definitely return them, but I need to act quick as my miners are idle.
I can make them myself, but I am looking for a ready made solution, that I can just buy quick.
Any ideas?

CYPER..
I just saw your posts, and I had the same issue you have with the VS650; using PCIE for one blade, and needed to use the ATX12V 8-pin connector. And I also got those fake "18 AWG" extensions, which when I stripped them had just a few strands, so I luckily refrained from using them.

The way I solved it is a little unorthodox, but it worked. I just FORCED the 8-pin connector into the Antminer's PCIE 6-pin connector the "wrong" way around, i.e. with the correct polarity (yellow wires inside, clip over the edge of the board), with the 2 extra pins just hanging outside the connector. It worked well for a while, and no wires overheating or anything.

However, a few days later, I started finding that the PSU would shut off while I'm away. It seems PSU is not happy with either the large current or large power. When I notched down the Antminer's speed to 300 MHz instead of 350 MHz, it now seems to be stable. Seems like the PSU is just really crappy and not really supplying the 600W it claims it can on 12V.

I'm thinking of using more 12V wires from the PSU, from other cables (SATA, 4-pin Molex, and the main motherboard connector), and screw them into the screw connectors on the Antminer, so the power for each blade would be spread across 6 wires instead of just 3. Has anyone tried something like this? Would this make any difference to the PSU's shut-off protection circuit?

Also, I've read that in some cases, if there is no load on the 5V lines, then the voltage drops further on the 12V triggering the shut-off. Could this be the case here?
