I’ve been using a nzxt c 850 and I had a asus card on it the other day working and oc fine

EVGA 1000 t2 titanium and list for a 3090 kingpin 
 
 

Well, If I have a chance to order one of these amazing 3080's I know I will have to order a new PSU ^.^ 

3090 FTW3 Ultra with 9900k and Be quiet dark power pro 11 850Watt no problems so far.

I don't suppose anyone would like to go back through this list and update the original post with which card each PSU model is running?

My original complaint with this thread. It basically is a counting thread, because of no ownership by the OP to organize it. I'm not sure why it was awarded a BR.
I mean 'Here is the list so far' is the sum total. List of what? Nobody really knows.

3090 Hybrid
i7-7700K
Seasonic 1300w Platinum
 
Had a Seasonic 750w Platinum before and my PC would shut down during games, no Problems whatsoever since upgrading.

3080 XC3 ULTRA, 5800x, NZXT NP-S650M (Seasonic SSR-650SGX), working

3090 Kingpin 
10900k
Super Flower Leadex III Gold 850W

3090 XC3 ULTRA + i7-7820X
BeQuiet Straight Power 11 750W

This is the 700watt fanless model, correct? I've been reading up one some potential Seasonic issues with their "older" Prime models not being able to handle the transient power requirements of the RTX 3080, and it's not clear if the fanless TX-700 is considered part of their "new" more robust Prime series. Your specs of 5800x, an overclocked 3080, and a fanless PSU are my ideal specs, but I'm worried that the PSU might not be quite enough, and I'm also not willing to spend an extra $100 to get a fan I don't even want with a TX-1000 or whatever.

Correct and it is clear that it's considered part of their "new" more robust Prime series as the TX-700 was released in spring of 2020. I'm not recommending this PSU for anyone else, but I've tested power from the wall and with no overclocking on my system, it's more than enough. Techpowerup recommends 750W with the 3080 FTW Ultra (link below) and while they're using things like Furmark to cover all the bases, scenarios like Furmark or Furmark and CPU stress tests running at the same time are not comparable to use cases I ever see myself being in.

I also have a 180mm fan blowing straight into the TX-700 and I probably wouldn't have put together this setup if the case I own (FT05) didn't accomadate everything so well. If you're worried that 700W is cutting it too close and really want a Seasonic, you could always grab the TX-750 or TX-850 instead of the TX-1000 mentioned in your reply.

Unsurprisingly, my 3080 running on a EVGA 650GQ rebooted mid-way through the 3dmark time spy benchmark. Looks like I get to figure out how to undervolt until my new PSU arrives.

It's great to know that it's working for your use case. I think fanless would work in my HAF X as airflow hasn't ever been an issue, and the price on the 750+ is much higher than you might expect for only a 50 watt bump - I blame current PSU availability. You've given me a lot to think about. Thanks!

Oh, I went through the exact same thing back in Sept, but there is no way I would have paid an extra $100 plus for the TX-700. I would wait until you see TX-750 for normal price which is ~$200. It was it on Amazon for maybe a day or so about 10 days ago. You could also set up a stock notification on B&H.
 
As for cases, I'm waiting for Silverstone to finally release their Alta F1, which was originally supposed to be released in Q4 2020, but they seem to be having production issues. I'll just have to deal with the external radiator on top of the FT05 until they get this thing figured out. Oh and it looks a lot better/more stealthy when the side panel is on lol, leaving only the fans and the radiator exposed.
 

New build, decided that 1000wats is the new comfortable

i9-10850k , EVGA 3090 FTW3 hybrid , EVGA SuoerNova G3 1000 watt

I don't think I've seen the 750w Supernova G3 come up as an issue yet, but here I am to spoil the fun.  Back in September I started experiencing random shut downs during gaming.  Interestingly it was almost always during a load change, as opposed to being an issue when running at full load.  I could run hours of benchmarks but then crash when going to the menu of a game, or when the game would switch to a loading screen.  However, maxed settings during regular gameplay was almost always fine, and sometimes I could game for hours without a shutdown.  All of this was with a 2080ti, 8600k, 32gb ram and a 750w Supernova G3 that was bought in 2018.  Assuming the PSU was the problem I RMA'd with EVGA and while waiting for the new model, I upgraded the CPU to an 8700k.  Still had shutdowns, so definitely not the CPU.  Also received my 3090 founders while waiting for the new PSU, but didn't have time to test separately.  Installed the brand new 750w G3, 3090 and off to the races.  Shutdowns began within the first 2 days of gaming.  So now I've replaced, CPU, GPU and PSU and still have shutdowns.  After reading about these transient spike issues I decided to not go nuclear and replace the MOBO, and instead bought a Seasonic Prime GX-850.  It's now been over 2 weeks without a shutdown, while doing all sorts of heavy gaming with the 3090.  I've been running Cyberpunk at ultra/psycho ray tracing and quality DLSS to really put a hurting on the system and no problems whatsoever. 
 
TL;DR
My 750w Supernova G3 couldn't handle my 3090 founders without shutting down.  Had to upgrade to a modern Seasonic (PRIME GX-850) to stop the shutdowns. 
 
Edit:  As an aside, I have very annoying coil whine/electrical buzzing with my 3090.  Doesn't seem abnormal but it's audible 8 ft away on my couch while gaming.  Only when the volume is up or when I wear headphones is it drowned out.  Strangely it seems to be worse when the GPU is around 80-90% usage and needs to modulate the power usage.  When it's running full bore at 99% usage the buzzing almost completely disappears.  Same with extremely light loads under 60% usage.

3080 FTW3 Hybrid, 5800X, both stock and Seasonic TX-700 seems to be working well.

So after my conversation with Shiki8, I bought a TX-700. What was great was that it was silent. What was not so great were the four shutdowns in three days running just a 3600X and a GTX 970 - still don't have a 3080. Even just Google sheets would trip the PSU. Going to return it and try a Prime GX-850 since it seems to work well for you (and is also $100 cheaper).
