GTX 1080Ti PC crashing, help please :'(

Just to keep this updated and for anyone in the future with the same issue....

Jinxpad emailed to say his friend tested it on his rig with no issues.

New PSU time unfortunately!
 
I heard a click when it went off. Almost sounded like a click of a switch sort of sound. Did you say you had a surge protector? Try running without using that. If same yea i guess new PSU time. For a computer to turn off like that after you have tried all the above usually indicates a PSU issue especially if cards was good in two other rigs.
 
And here i was lead to believe NV cards are green when it comes to supping the juice :D:D:D Does sound like a new PSU will sort the problem. I am not sure how old the psu is but a 1250w from xfx shouldn't be having this kind of problem. I would be confident running a 1080ti on my 6 year old 750w corsair as it's easily handling an overclocked 290.
 
Thanks for all the help guys, yeah my friend is bringing the card back tomorrow, and we're gonna try one last thing, I did some reading about the PSU I have, and it's "Easyrail" system... Turns out that its not just 1 super rail but 4 separate 12v rails, so we're gonna try one last thing my friend suggested, which is to try powering the card from two separate PCI-E cables and spread the load across 2 rails as I have a good amount unused. Any thoughts on this idea?

This is what I was writing last night:

A PSU with separate +12v rails (not combined) could be one explanation.

And then didn't post it because why should we guess, when you can say which PSU and remove all doubt (which you've now done lol)?

And yes spreading the load might work. Seems each separate rail doesn't have the amperage for a 1080Ti. Your motherboard was trying to help through the PCI-E slot itself but couldn't cut it and giving you warnings.
 
Sounds like one of the rails on the PSU can't handle it to me. I always run 2 separate cables from a modular PSU to a GPU to prevent such a thing and hopefully this will work for you too
 
I tend to avoid PSU that offer multiple rails unless it's a top end PSU with a high ish rated wattage for load balancing. Anything under 700 watt i would not consider multi rail.

Is this why I see so many with the loop cables?

If the PSU really is the XFX Dark Edition Pro 1250 (you've not confirmed yet), I've just been reading a Johnnyguru review where he says its "Easyrail" is actually one single rail instead of multi. So can you please confirm. http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=273

That is indeed my PSU, and also the article i was semi reading through last night. At the end in his conclusion:

"And for good measure, let's review some of the marketing goofs:

  • EasyRail is a marketing term for a single +12V rail, but this power supply has four +12V rails."

Aha! There we go then.

I stopped reading after the page I linked you to. That'll teach me. Cheers.
 
So it should work, you just need to look at what cables you are using.

So it's a Seasonic X-Series 1250W (using similar caps) with silly OCP added. :S

I was plugging the 4+4-pin into my load tester and the 4+4-pin shares a +12V rail with the 24-pin connector; so putting a load on both of these connectors was putting the total load on one +12V rail.
Click to expand...

Now that we got that all figured out, I unplugged the 4+4-pin power connector and used the 8-pin CPU power connector and plugged it into the +12V4 connector that can be used for either an 8-pin CPU power connector or PCIe cable.

Right having had a good look at the Modular connections on the PSU.

It looks like you can use the PCI-E/CPU connector to power the CPU.

Normally this would be a no no, as PCI/e & CPU power connectors are not compatible. But that 8 pin CPU cable must be designed to use this special socket. Only plug it into the socket marked PCI-E/CPU which is out on it's own.

Then you just need to work out if any of the other PCI-E connectors are on the same OCP line.
 
You might not want to hotlink the image.

Use the one marked with a tick for CPU power, you'll need to use a different cable, the 8 pin CPU cable. I'm assuming you had the one with the cross in use before.

Then just try different combinations of PCI-e for you GPU.

I'll be double checking tomorrow, but according at least to the remaining cables I have in my box, the CPU power is plugged into the socket marked with a tick in your image. If this is the case should I try using the dedicated 8 pin CPU cable to power the CPU?
 
Check what connections you have at the moment, I was expecting you to be using the one marked with a cross at the moment. As that was how jonnyguru had it connected at first which gave him problems.

But you can try different combinations of CPU and PCI-E cables and see if that fixes it. Some how you are hitting the 20 A OCP on one of the lines. Or it is faulty and the OPC is kicking in at a lower level.
 
Ok guys so here's the update,

Running the graphics card from two separate PCIE connector cables didn't make any difference, the PC crashed out pretty much the same conditions.

However one strange thing that happened is we swapped the CPU power cable from the PCI Express /CPU connection on the PSU (TICK) to the dedicated CPU power connector (X), and while initially the PC would still crash at the same spots, when I reset the BIOS to optimise defaults, removing my current overclock, the system now seems stable.... we're still testing ( black Desert Online is running currently while I'm writing this post).

So changing the configuration of the cables has stabilised the system but only without my overclock so far.

My next question is does this still sound like a power supply issue?

As I'm happy to run at stock speeds until I purchase a new power supply, I just don't want to risk buying a new power supply only to end up not being able to apply my overclock and running to the same problem because it's actually a different component causing a problem.
