It's been like this for months.  For that reason I ended getting this 850W PSU for my new build since it was readily and reasonably available.  Looking forward to seeing how it'll fare with my "eventual" 3080 series card. Glad I didn't go for anything less powerful, but wonder if I should have gone for 1000W...at the time it seemed like overkill for my needs.

 

The Tough power is a decent quality unit, and single rail. So it should be fine. 🙂

Is that a single rail or multi-rail unit though? If multi-rail, the OCP is set low on each 12V rail. If so, may have just been a load balancing issue.

Nope, it's a single rail psu, it was a seasonic focus platinum. I Even swapped in a seasonic prime 750 and it tripped but took longer to do so.  No issues with the 1000w unit that's now in there, even with the unlocked bios.

Well there you go.

I guess those of us who advise moderation when choosing PSU wattage and proclaim 1000 watt PSU's a waste of money are going to have to reconsider that advice.

In the past that has always been me, things have changed this time around with these new cards.

I just bought a new PSU to power my new rig since the old psu was about 10 years old. Not sure how much more life is in that old girl but I will keep her for a backup now. I first went with the EVGA 850W GA since it was the only thing that my microcenter had in stock above 750. The evga shut down within minutes of gaming with the 3090. EVGA knows these psus wont work with 3080 and 3090 cards yet they are still on the shelves. There's a big thread on their forums where everyone with this family of psus has problems with shutdowns on 3000 series cards. I ended up removing that pos and returning it to a different microcenter 30 minutes farther away that did have the asus psu that I wanted to begin with and it works perfectly with the 3090. All in all I figure evga cost me about $500 in total of my billable time to install, remove, return and replace their known defective psu for one from a different company...

I'm wondering if its the POSCAP issue at work here. The use of POSCAP's on some of the cards has been associated with issues. Basically the cards were turboboosting beyond the cards capabilities. Many of the manufacturers have modified the bios now to correct the issue. It could be that a more hefty PSU was somehow overcoming the issue. 

Just speculating, but Nvidia did tell us that 850 watt should be sufficient. Unless of course the guys with issues had hefty overclocked CPU's plus additional out of the ordinary load.
