Seasonic Snow Silent 750W good enough for 1080Ti AORUS extreme?

[thejunglegod]

Got myself a new GTX 1080ti and it's been giving me weird pc restarts. The ones I associate with problematic PSUs. My worry however is that it's only been around 6 months since I've been using the Seasonic Snow Silent 750W PSU and it has never given me any trouble with my 980Ti.
To double check, I reinstalled my 980ti with the appropriate drivers (clean install with DDU) and I get no crashes. I seriously hope it's not a faulty card issue.
Any pointers on how to go ahead with this? Is my PSU good enough for this card?

The recommended PSU wattage for that card is 600w, so 750w is plenty.

However, that PSU has a pretty low rating for a Seasonic unit on Newegg. Maybe you have a friend where you can try the card in a different PC to see if the issues persist. If not you can take the card to a local PC repair shop for them to test it, or buy another PSU on sale ($40 - $70), and test it that way. This way you will have a spare PSU to troubleshoot any future issues.

Hmm...Buying an other PSU right now might be a little difficult considering the amount of money I've pumped into the card. I'm reading in a lot of places though about the power supply not being juicy enough(quality wise). I honestly thought that since this is 80+ Titanium certified, I wouldn't face any such issues.
One more thing, my Mobo P8Z68 ProV Gen3 is quite old (Around 5 years). Could there be some issue with respect to that as well?

You can try lowering the clock speed and/or undervolting of the card, see if the system becomes more stable.

Could be. However, until you try the steps I suggested in my first post, you won't know for sure. PC hardware troubleshooting is a process of eliminating components. Otherwise it's a guessing game of "maybe it's this, or maybe it's that".

Step 1: Try card in another PC or have it tested at a local PC repair shop.
Step 2: Try a different PSU.

Hopefully one of those first two steps are the issue. However, if your 980ti works fine while installed, that would lead me to believe it's not your motherboard that's the issue. If it was, you should experience the same problems when it is installed.

All manufacturers (even the good ones) occasionally make bad/defective products. From the user reviews I read, the PSU model you bought might not be one of Seasonic's better products.

Ok, so an update. I managed to get my 1080ti to a friend's place and get it tested. It worked perfectly fine. So i assumed it must be my power supply.
Just for kicks, i decided to connect my power supply to his pc and weirdly, it worked as well. No crashes/restarts even after a half hour of gaming.
I'm seriously beginning to consider that the fault is somewhere in my motherboard. Any thoughts guys?

What board does your friend have? Do you have the latest BIOS for your motherboard?

Yes, I flashed the latest bios for my motherboard. My friend has a relatively newer motherboard compared to mine. And it posed no issues whatsoever.

Make sure there isn't a BIOS update for the new GPU too. You could try a different PCI slot on your board. Also, did you reset the BIOS back to factory when you installed the card. Might be worth a shot. Beyond that I'd reinstall Windows in the off chance something is not playing nice. After that it could just be the board or something in the board's BIOS that doesn't like the newer card.

BIOS update for the GPU? damn, keep learning new things all the time. Alright i'm searching for it but does flashing a new bios void warranty?
Also, I did reset my Motherboard Bios after installing the card along with trying it on the other PCI-e slot as well.
Just a serious bummer this. All things seems to be pointing to the motherboard.

No, it doesn't void your warranty as long as it's an official BIOS update from the manufacturer. It's really no different than updating your motherboard's BIOS.

Also, what motherboard do you have? If it's old enough, sometimes newer cards simply won't work with them. Rare but I have seen it a few times over the years.

Edit:

I saw the model in one of your above posts (P8Z68 ProV Gen3). The newest BIOS update for it was in 2015, so if after [possibly] updating your video card's BIOS it still doesn't work, and since you've already tried it in different PCIe slots, you might just be one of those rare cases where they are simply incompatible.

Edit 2:

Try this suggestion I found in another help thread with the same motherboard:

http://www.tomshardware.com/answers/id-2683672/gtx-980ti-asus-p8z68-pro-issue.html

If you have the version of the board that supports PCI-E V3, try setting it to run in PCI-E V2 mode and see if it will boot. Those first gen V3 boards with Z68 chipsets are a bit finicky so it could be that.

I don't know how i'm supposed to do that. My motherboard is Pci-e V3 ready but it's still only running on pci-e V2 as per GPUZ.
Is there a setting that i'm unaware of in the bios?

No, you should be good then. It was just something I came across that might have helped.

A positive update guys.
I tried using the card on a friend's pc as @UsandThem suggested and there seemed to be no problem with the card. So i assumed it would be the PSU. I then decided to test my PSU and my card both on his computer and strangely enough, it worked.
So i got myself a cheap new gen3 motherboard(which was very very difficult to procure) and the card now works with absolutely no problems.
I would like to thank each and every one of you for all your contributions in helping me to fix this issue. Couldn't have done it without you guys. <3
