Title: Re: Melted PCIe cable, PSU still OK to use? Post by: dogie on September 08, 2014, 05:43:24 PM Those 3 pins are all 12V, its not a short, its just too much load. Up to you if you choose to continue to use the PSU, no one can choose your risk level for you.
Title: Re: Melted PCIe cable, PSU still OK to use? Post by: DrG on September 08, 2014, 07:40:53 PM Why donīt you just open it and rewire a new 6-pin connector? Opening it voids the warranty. EVGA is good with RMAs but they don't want users trying to service things. Title: Re: Melted PCIe cable, PSU still OK to use? Post by: wh00per on September 08, 2014, 07:47:31 PM I guess the compressed air was the culprit .. since it's cold when it expands and I dunno what humidity levels were there.
The things get hot when they have a resistance load to dissipate the heat, in this case, the cable was the weaker link. If you spray then up, give them some time before you plug them back in. I usually vacuum them and dust them up using a paintbrush. Also, make sure you're grounded (just in case) to avoid damaging parts by static electricity. You can use the other ones onward, no worries. But take more care when you clean them up. Title: Re: Melted PCIe cable, PSU still OK to use? Post by: Soros Shorts on September 09, 2014, 01:10:29 AM Maybe that particular S1 board has developed a fault and is now drawing more than the expected 207.5W?
When you turn the miners back on, you should check to see that they are still drawing 830W and not something significantly higher. Title: Re: Melted PCIe cable, PSU still OK to use? Post by: Blazed on September 09, 2014, 01:15:06 AM I had a PSU do the same thing and it still ran fine. We're you using only 1 cable to power the ant? As in 1 cable that has 2 x PCI-e connectors on the end? You should be using 4 PCI-e cables off the PSU to power 2 ants.
Title: Re: Melted PCIe cable, PSU still OK to use? Post by: jddebug on September 09, 2014, 02:21:38 AM My guess is when you plugged them back in you didn't get it on tight and that caused a poor connection and it heated up and burned. Should be fine when you replace the cable.

It helps I live 10 miles from them but the RMA was very easy - no hoops to jump through. I had a Seasonic 750 melt a cable like that when connected to my BFL Single. I still don't know if it was the Seasonic unit, the cable or the BFL ASIC. Title: Re: Melted PCIe cable, PSU still OK to use?

I've had great success sending in dead power supplies to evga for a replacement. http://www.evga.com/support/warranty/ I would definitely RMA it if I don't have to keep any antminers switched off because I dont have any PSU left. If I have other PSUs, I will see if the problem is with Antminer itself. Also, I don't think anyone's gonna suggest you try to use this faulty PSU anymore even if you have plenty of cables and pcies left. |
