New 3080 Installed. Yay! TW3 Restarting PC. Not yay

you could RMA for them to test I guess
You can either drastically undervolt the gpu so it uses much lower power that will confirm it

Or buy higher capacity PSU I would go 1000w+ if want to future proof might be better to do higher considering whats being talked about power usage on next gen

you can RMA it.
I had a focus+ previously and RMA-ed it. i got a focus GX back in return with sorted out the OCP shutdowns
the RMA service was very fast and hassle-free
actually seasonic will accept the RMA, because it is classed as a fault (and has done since the vega64 days)
and i've also previously RMAed my focus+ due to the same issues that OP is facing
Appreciate the answer. It's not as simple as that. IMO 750,gold 80 rated is ample for this system. Yes, I have an 8700K overclocked and a relative power hungry 3080 that takes 320w under load but you (figuratively, not aimed at uscool) can't tell me that the rest of my system requires the remaining 430W? I'm generalising here, I know I can't count each w out like that but you get my point, that the issue is not 'lack of watts'. Seasonic themselves are saying their protection is sensitive and something is almost a false positive for lack of a better word.
I will contact them and try my luck, though I suspect I'm in for weeks of "it's clearly the new GPU at fault" from them.
Yeah I corrected myself they can test it and confirm if it's ok or not
Just doing the undervolting could answer the spiking is probably causing it 750w isn't that much
Also hasn't said if he has saperate PCIe cables connecting to the gpu or daisy ?
My concern is that I've had this psu for four years, might not have all the cables/box etc. I'll give them a message. Anything you recommend I mention to speed the process up? Any key phrases you used etc? Thanks.
Before doing all that why not try the following it's pretty easy to test
Why not undervolt so gpu uses like 250w Run the ram and CPU at stock and test again ?
Well in the interest of transparency... I'm an using two separate cables on the 3080, BUT I was using a single connector daisy chained for 4 years on the 980ti. Total oversight on my part because 'it worked' and I honestly didn't know it wasn't recommended.
First task of today. Soon as I've had this bacon butty I'm cracking on...
@Amraam
nothing specific...just a description of the problem
you won't need to send it the full set - IIRC just the PSU and the 24pin cable (been a while since I RMAed my unit - I'm sure seasonic will remind you what you need to send in)
i think i said something along the lines of: "upgraded to a 1080ti, since upgrading GPU, constant random shutdown/reboots. tried GPU in second system with different PSU with no issues. Tried Seasonic PSU with second system and 1080ti and random shutdown/rebooting under full load happens again"
(i did actually have a second system to try though)

Yup. I saw that on a Jayz2C video recently and instant self reflecting facepalmYeah it's recommended to use each PCIe cable from PSU and not daisy chained
Suffice to say I considered myself lucky and very stupid and confused as to why I didn't realise it sooner. Alas, the 3080 is correctly connected, I just hope having it connected this way hasn't attributed to my issue...

Did that fix it? Are you able to play The Witcher 3 without it restarting?
OK so just installed MSI AB and set up a profile. Dropped the Clock:Voltage curve down by ~100mV and The Witcher 3 fires up beautifully. Getting 100FPS constantly but getting the odd stutter as the FPS drops occasionally, presumably due to hairworks etc. Going to restart and put my OC back in and continue testing.
Quick question about this undervolting though... it seems quite popular, and a lot of people showing evidence of reducing power consumption by 33% at times with little to no performance drop. Why is the stock power consumption so aggressive if it can run stable and safe with such a massive drop in power?

Not all cards run the same so they pick settings including voltage that will make all the cards (in theory) run stable so that they don't get returns. Plus when a gpu is reviewed that review is often based on fps and the general population like higher fps. So the manufacturer often aims for higher fps rather than good power usage, the 3070ti is a good example of that this generation. Here is a good example of looking at the sweet spot on the Vega 56, AMD Radeon Vega RX 56: Overclocking, Efficiency & Temperature (tomshardware.com)
Have you tried leaving the card at stock settings and capping the fps to 60 or 75 fps in the nvidia control panel, hopefully that will reduce your power usage even more as you are running under 100 fps

so if its working now the power was too much for the PSU ?
personally wouldnt wanna drop back to 60 just feels stuttery now especially when panning around after getting used to 100fps+ even notice the difference in normal windows use , I would also use MSI AIB overlay so you can see how much CPU is getting used when it stutters and keep eye on GPU clocks and temps power usage etc
I see that you have Acer Predator X34A 1440p 100 Hz
I would search the model of 3080 you have for undervolting so you have an idea what to play around, Personally myself I wanted to match stock performance with undervolting but ended up actually beating stock peformance while lowering power use and lower temps

This is my line of thinking too, however I'm not treating undervolting as my fix, but instead more of a proof that the PSU is acting up. I've made a custom curve in MSI AB which keeps my boost clock at 1850 but doesn't let lowers the voltage to about 950mV. Stable so far, and that's with my CPU clock bumped back up to 4.8Ghz.
The next test is to run Cinebench and V-ray together and see how that works. Fingers crossed Seasonic will reply with good news (or at least not immediately "it's your GPU, go away") and that I'm not running like this for too long. If I don'r hear back from them within a week I'll just have to cough up and order a replacement PSU, as I don't want to rely on this fix when it's fundamentally a hardware problem
Probably doesn't like the sudden spikes consistently going up and down that comes with gaming
Still would have thought 750w gold and decent model would be enough unless it's lost something being the age it is
Guess you can return it for them to test it out but would be without PC to use while it's returned
