Please help. Replacing pci express male connectors on Antminer C1.

[Roccdrummer]

Hello.  The antminer C1 has 8 pci express male connectors built into it.  I have been powering it with two EVGA 80 plus bronze 500 watt power supplies.  That uses 4 of the plugs (two for each supply).  All was well for like a year, then the power supply pci express connectors melted into the board's male plugs and I had to RMA the power supplies because the plugs were melted.  Thankfully, they let me rma those.  The male plugs on the board had the power supply plugs melted into them.  Luckily I was able to just go ahead and use the other 4 plugs once I received the new power supplies.

Well, the same thing has happened again.  The power supply plugs melted into the board plugs so now all 8 plugs on the Antminer are ruined and need replaced.  Is this easy to replace the male pci express plugs built onto the C1 boards?  Do I need specialty plugs of some sort, or can somebody tell me how to do this and where i get the replacement plugs?  Pleeeeassseee?  I'm not sure if they use typical pci express plugs.  It looks like i need to unsolder the 6 pins from the opposite sides that connect it to the board, but there are six L shaped metal connectors that plug from the board into the bottom of the pci express male plugs.  I seen some replacement plugs on Frozen CPU so far, but they are just all plastic, with no metal or even holes where you'd attach them to the board.

Hopefully they let me RMA the power supplies again.  But I will definitely need to replace the male pci express plugs on the board as well.

I'd highly appreciate any assistance and advice that the community can provide me.

If a psu kills your miner once... don't   go  back to using it again.    If you do it again a 3rd time I suspect we see same thing.

But post pictures so we can see how bad it is. Likely someone with some soldering skills would be able to fix it. But again we need more pictures/details to tell much.

fool me once shame on you fool me twice shame on me.

or stupid cheap .

or pennywise pound foolish.


the c1 is not meant to be powered with those thin wired pcie cables.




you will need a solder guy to repair it  .  there are members that could do this for you. I suggest going to market place thread and offering to pay for a solder repair.

and get some real psu's

I can solder repair stuff, I'm just wondering about the plugs...  where to get the right replacement plugs on the board.  I'm thinking I have to keep the metal parts of them, while just replacing the plastic parts?   I think they are different than normal pci express plugs.  I'll try to get some pics uploaded as soon as i can.

Thanks very much for replies.

I think i recall seeing them on frozencpu, but i dont know what the thing you refer to is called.
http://www.frozencpu.com/

I'm guessing if its common-ish to find, its going to be on that website.

give j4bberwock a pm

and don't use those psu's with the gear.

That last post shows the exact kind of pci express connector that I need.  How do I find the L shaped pins?

Thanks so much!

Take molten plastic away solder gold plated bullet connectors to the hash board wires.

This is quit old miner is there any point of stock looks better thing would bee fireproof miner?

3-4mm bullet connectors which are used in RC Motors and batteries can take upto about 90A.
