Have I fried a GTX1080ti?!

Hopefully someone can help a very desperate man out here. I have this setup that I built myself, i7 5930K, 32ddr4, 2x sdd, GTX1080ti Seahawk, MSI x99a mobo, antec 850 psu (which is 9yrs old).

I fitted my new 1080ti as a replacement for my old 970 and instantly noted a much longer system start up speed. I never paid it much thought however.

Last night, I used MSI afterburner to increase the voltage and boost clock speed by a small increment (+30). This work really well with a max temp of 50 degrees Celsius and improved FPS.

Now this morning my computer wouldn’t turn on. The 1080 LED flashed for millisecond then nothing. I then removed 1080 and mobo battery replaced them and still no luck. Next step, I removed 1080 and replaced with an old pci e card and the rig booted as normal. I proceeded to reset windows deleting Afterburner in the process.

I replaced the old card with the 1080 and still millisecond flash of LED and nothing. Interesting when I remove the two 8 pin cables but have 1080 fitted in PCI-e I get power on shown by fully lit LED.

Pleading with the PC tech byte community here. Can anyone help me figure out if my new card is fried?



Thanks!
 
I’m in no way an expert, but I’m wondering if the PSU could be causing the issue. It’s quite old and not the best of makes. It might not be very stable. Failing that, it does seem like an RMA could be in order.

I’d wait for some better heads than mine though lol
 
First thing would be to try a different PSU, if you can perhaps borrow one from a friend. They are not expensive however, and you are well overdue with something that old.
 
you don't want to increase voltage because of the way GPU Boost 3.0 works. you get better overclocks on pascal by undervolting.

volts = temperature increase = throttling
 
Thanks Guys. I’ll hold off on the RMA for now as a last result. :-).

I’ll invest in a new PSU. I totally agree it’s in need of a replacement.

Once I test this out I’ll report back here with the results.
 
I think it would be a good idea to replace the PSU anyway, although they are a lot better than they used to be, switched mode PSU's do tend to degrade somewhat with age. After that try the new card then if that doesn't work I would actually risk a motherboard BIOS update. The reason I say this is because you say that you noticed a much longer system startup. A BIOS update is something I normally don't suggest because it can brick your motherboard, but issues with graphics cards sitting there pretending to be dead often turn out to be the BIOS. Failing that then return the 1080 :-( A BIOS update is not to be taken lightly. You must be absolutely sure it's the right BIOS. If there is even the slightest doubt then don't do it. You should never do a BIOS update unless you are prepared to replace the motherboard. If there is any doubt then miss that step out and just return the card. If the supplier tells you there is nothing wrong, or the replacement doesn't work then you have to decided whether to upgrade the BIOS or stick with the 970 for a while.
 
Thanks Pocah. Can I put it to the thread commenters here and ask for recommendations for a new PSU?

I am prepared to invest in this piece of kit so please feel free to make any suggestion for any buget.

Thanks again all!

Thanks guys. I have some news. Following advice I bought a Cosair 750w. Plugged in my graphics card and...it went on fire. Not metaphorically but real spark am smoke.

Guess that I’ve truly fried it. Any suggestions about to do next will be greatly appreciated. Today is a bad day
 
What Corsair PSU did you buy? It could be that your old PSU weakened the card with poor voltages (rippling) and that when you gave it a decent PSU that could power it went bang. Just setup a RMA say it died and you'd like a replacement please, I'm sure they'll sort you out I had the same issue with a different retailer and they collected my old card and drop the new one off at the same time.

Considering Pascal is hardlocked voltage wise I just banged my voltage slider to 100% in MSI Afterburner and the boost improved nicely.
 
Go on live chat on amazon and say it’s just stopped working don’t mention anything else

They will send you a replacement
Amazon best customer service on the planet
