Been trying to test this new 290x with mining, random restarts, computer hangs, card isn't OC'd

While troubleshooting all the things that could be wrong I decided to replug the connectors in my PSU

This seasonic x 750 has been good to me for 1.5years

While removing the pci-e for the ONLY 290x in my rig I notice the connector is MELTED.


MELTED. I couldn't even remove it, so when I did, obviously the black pieces on the connector broke off.

I'm going to RMA this thing but, no single rail was completely overloaded, this is a gold rated 750 watt power supply and I'm not even close to reaching that limit.

So RMA or not, did I have a unlucky psu? What could have possibly gone wrong frown.gif I am assuming the short is what kept causing the PC to restart, but to be honest it was more of a screen goes black, everything is still powered on(gpu fans spinning , cpu fan spinning) ? I still don't know if this was the main reason for that or not, still have to test bunch of different things

Here's some bad quality pics for you to see

this is the 2nd Seasonic PSU that I have seen do this in less than a week. See this thread.

What it looks like to me is that seasonic has a +12 and a negative crossed. because the PSU should not cause this it should be a short on the other end. and you see it here because this is where the heat would start first, or maybe the ribbon cables they are using is allowing a short.

Good luck Hulk.. interesting to see what happens because I know seasonic is going to blame it on what ever you had it hooked to. Unless they know they might be a problem then they will replace asap to keep you quiet....

loose connection high resistance creates heat and melts the connection.

how much slack was on the cable?

that is also a possibility but it looked like the connector was tight to me in the pictures but might be bad pins not making good contact causing this also... I have removed the factory pins from psu connectors and found some that was not stripped out and had been crimped to insulation....

Thanks man, I really hope not.
I would be quite aggravated with seasonic. Everything on my PC is fine except this destroyed cable that was melted into the PSU.

Really sucks that happened to RAFFY, much coincidence happened on a 290x eh. Guess tomorrow will be one of those fun days.

There is no loose connection I plugged the connector into where it goes making sure that it clicks in place.
I used this power supply for 1.5 years and after putting in a 290x this happens? Sucks for me frown.gif

problem might be with the 290'x also pins hooked up wrong or something like this. If you guys have problems need to get together so you can prove it not just one time happening. let us know how it turns out!!

Customer service is a big thing to me. I will pay more for good service and have in the past and will continue to...

It has to be a problem with these power supplies and the 290x. Mine was hooked undervolted, and the psu was running at 80% capacity at most. So far Seasonic has been great. They paid for return shipping and are willing to reimburse for damage to my computer case once I send them pictures. So far they have been great.

I just hope they are the same with me, thank you for sharing me the experience.

I'm honestly afraid to get the Seasonic X 1250 now and am considering a Corsair 1200i with the single 12v rail.

I've never been more glad to not finish the sleeving job. I'm sure all the paracord bunched up might of had a different effect if 10 wires burnt up at once. A sleeved pci-e cable could of ended up costing me my home rolleyes.gif
