You might consider power

You might consider power limiting the 3080Ti and see if it makes any difference. Your FTW3 version comes stock with a 400w limit, and configurable up to 450w. But limiting it down to 300-350 might help control spikes with marginal reduction in performance.

Yes - I've already done that, runs fine with the limit set.  It just annoys me to no end that a power supply that should run in ECO mode absolutely will not.  That's why I decided to go back to Seasonic, the only problem I had with my Seasonic 850 was it just didn't have the Horsepower to handle the 3080TI along with the rest of the system.  We'll see how the Seasonic 1300 does...

Just be aware... Do you have

Just be aware... Do you have a Seasonic Prime or Focus ?  The Prime units may potentially shut down unexpectedly.

It better not!  Yes the power supply (Should arrive on Monday) is the Prime Platinum SSR-1300PD.

If it does, try this before you trash the Seasonic Prime SSR-1300PD:

"It is recommended, if going with such units, to overprovision wattage, 1kW for RTX3080 and 1.2kW for RTX3090, or power-limit the GPU, or performing a 'dirty' fix of disconnecting a pin of 12V V-sense wire from PSU-side connector of 24-pin motherboard cable (courtesy of Jonny Guru)."

Went to reddit and did a little research, I should be fine. It looks to me like a lot of those guys are running their systems a little thin on power anyway.  As for disconnecting the sense line, before I did that I would just loop the 12v output back in to the sense input.  That way the power supply should attempt to maintain an accurate 12v output.  By cutting the sense line coming from the MB and providing nothing for an input the sense circuit will probably go to max offset and sit there while the actual output floats based on load.

OK, been running the Seasonic

OK, been running the Seasonic Prime PX-1300 (SSR-1300PD) at max load for a day. (In ECO mode no less!)   By any name it's a helluva power supply.  With the EVGA supply using GPU-Z you could see the 12volt rail bobble maybe a tenth between tasks during the load swing, with the Seasonic it's rock solid.  Of course the real tell is the EVGA couldn't run 4 hours in ECO mode without shutting down the PC.  A real shame, I love EVGA's support and would have preferred to stay with them...

What’s the obsession with

What’s the obsession with running the PSU in eco mode? If it’s working in normal mode I don’t see the issue.

So I guess you're ok if you buy a new 4 slot toaster and only 3 slots work.  I mean most of us only make two slices of toast at a time right, so whats the problem?  Or if that doesn't do it for you, perhaps you bought a new car but the AC didn't work, you ok with that??  See my point?

To further clarify; To me having purchased two of the exact same model and had them both fail in the same manner can only mean one of 3 possible things;

1: Poor quality = I dont want it

2: Poor Design = I dont want it

3: Deceptively rated (ie rated as 1000w but is it really?)  = I dont want it.

 

OK I'm done crying.
