Depends on how bad you need it. If the psu fails, you will get upgraded to a better psu. You will have to wait. And possibly reach out to Jacob on Twitter so you can get faster service. Been a month since I contacted EVGA about my 850 GA.

Wow, I know EVGA gets a ton of credit for their customer service and I had the opportunity to experience it first hand.  Just called regarding my 850W GA and the guy on the phone instantly said that there were some reported issues and offered to swap it out with a different model.  It was seriously painless and the guy I spoke to was great.

Do we have any consensus that this is a problem with pairing a GA PSU unit with a 3080 card yet?
My PC parts are about to arrive and would like to know if I need to return my Supernova 750w GA.
I cannot, unfortunately, chance on testing if this issue exists because the place I purchased from doesn't allow returns if their product is opened.

At this point I would NOT use a GA with a 3080 or 3090. Do a couple of searches and you'll find a ton of people with problems, return it if you can.

After getting confirmation that I'm receiving a 1000w G3 psu as a replacement for my 850w GA, I can't complain too much. It took much longer than I was prepared for. Almost a month. But after contacting Jacob on Twitter, he got the RMA processed within hours. If you can wait and want to roll the dice, buy the $150 GA model, return if the same problem occurs and get a $230 psu as replacement. I couldn't have done this had a not had another psu to use while waiting for the RMA process to complete.

I am really disappointed that EVGA has a community forum and rely on customers to communicate and troubleshoot these types of issues on their own. Maybe this issue is minor and not as widespread as other issues but, either way, it's a huge problem for any customer when they install their shiny new gpu only to find out something is wrong. First reaction will be to contact the gpu manufacturer in many cases. Hopefully someone can search and find a thread on here or Reddit before investing too much money on products like these and avoid it.

The major problem with the 850w GA is, it's the cheapest EVGA PSU with at least 3 vga connectors for 30series gpu if you sort on PC PART PICKER. I know that is why I chose it. I sorted by EVGA because I know they have a good track record for customer support. Next I sort by 850w minimum. Then if you sort by price, more times than not, you will see the GA as the likely choice.

What? The GA has known problems, you yourself even had problems and if I'm reading it right it took them a month to resolve it for you. Why in the world would you recommend rolling the dice on this? Also, you're not guaranteed a 1000w G3, they're sending me a refurbished 850w G5 to replace my brand new 2 month old 850w GA and others have said they're getting the same thing. If I had the option I would return my GA in a heartbeat and get something that works.

I never recommended it. I said "if". And provided my experience. Take it for what's it worth. If you want to argue, find a brick wall.

You replied to me, said pretty much the opposite of what I said, and you're accusing me of trying to start an argument? what in the world...
 
Also, how is saying "If you can wait and want to roll the dice, buy the $150 GA model" not recommending they roll the dice?

I am running a 750GA and have not had any issues. I've ran multiple benchmarks in Timespy and plenty of gaming with no shut downs or black screens. My 3080 FTW should be in today so that will be the real test.

Just a follow up, I'm just using my existing SuperNova 750w G+ from 2018 for the moment while I wait for the backordered AX850 and it seems to be running the Ryzen 7 5800x and 3090 just fine though so I'm wondering if I should just cancel the order for the AX850.

Hard to say, if it is working without issue I personally would not replace it. 

Received my replacement PSU today.  They shipped me a new in box 1000w G3

For those that received replacements for their GA PSu... did they require you to send in your current PSU before sending out the new one? Working from home right now and I'd be kind of screwed if I have to send this one in for the time being.

I used the cross ship option for mine so I had to put down a refundable collateral payment, but it made it so I had the new PSU in hand before taking out the old one. 

Well EVGA messed up my RMA on my GA 850 and just sent me another one instead of a different one... Just thankful I have a be quiet PSU arriving today otherwise I'd be screwed for another week... Yay....

I have the 850 GA paired with a I9 10900k plus 3090 ftw3 and can confirm that it is having problems. With or without over clocking my gpu I get random restarts. I’ll be able to narrow down wether it’s the power supply or the gpu when my new power supply comes in.

Here's the problem, I don't live in the US

Did you solved the issue? Definitely the GA Supernova doesn't work with the 3080?

What PSU are you using now with the RTX 3080?

bought a 850 ga 2 months or so ago. with 1080 fine. got a 3080 ftw ultra, psu whining so loud now under load. rma 850 ga replacement coming in a few days. will update
