Since I have and before I owned a 3090 I was running into issues with this power supply turning off because of the over voltage protection, not entirely sure this is the issue yet but based on the symptoms outlined down below I think is the issue. My previous card a EVGA GTX 1080 FTW DT was tripping this same issue as well but less consistently.     

 

Symptoms:

When under high load, sometimes even at idle, the power supply will turn off and the test light on the power supply will turn red. After the power supply will not turn on till you hit the power switch in the back and sometimes this does not allow it to turn back on and you will have to unplug and plug back in a cable (it did not matter what cable tested with 4 different pci, 1 sata, and the 24pin).

Happened for both the 1080 and the 3090 but when I tested with a ASUS 1070 the problem would not occur.      

Tested a Corsair RM750W power supply for both cards and the problem did not occur.    

I reached out to Corsair about 2-3 months ago and got an RMA for the power supply, this did not solve the issue. I am willing to accept that I got 2 bad units but I find it improbable.

 

What I am looking for: 

I need assistance diagnosing this issue.

If you can offer any advice or something else to test I would be happy to test 

I am looking for a power supply that can handle this card as the 750W is not enough for this setup.

Any other advice would be great. Thanks in advance.

aaaaand it's gone. Don't post the same post multiple times. That's just spamming.

My apologies fairly new to the forum

Min of a high quality 850W PSU.

 

That card pulls 500W+ so...

 

I would recommend getting a 1,000W PSU, 850W will work, 1000W for more headroom.

 

Something like these and known to work fine.

 

Corsair RMX 1000W

RMI 1000W

HX or HXI 1000W.

In the post I note that i tested with a 750 but if you look in the part picker it shows that I have Corsair 1200 Axi

If the light is turning red on the PSU contact Corsair. (Granted that is an OLD model AXI)

 

Current Models are AXI 1600 and AXI 1500

 

That is the beauty of the AXI...

The 1,200W is Discontinued.

 

Not even on the website anymore.

 

I do know that the AXI 1500, 1600 and 860 do work. (Current models)

 

As do the HX and HXI 850's and higher and the RMX and RMI.

 

 

[Jqwop]

Do you know why? And interesting so I know what I need to get for a new power supply thanks for the help.

I own 3 of them and tested them myself, AXI 1600, HX and HXI 850's.

 

And there is a list over on the EVGA forum of known working units on top of that.

 

I don't know why your AXI 1200 isn't working, could ask.

Are you using two seperate PCIe cables or two connectors on one cable? 

 

Have you tried switching to single +12V rail in Link/iCue?

3 8 pins all separately connected to the psu. I have not tried switching to a single 12V rail.

 You. I just watched a video, that you were mentioned in, on this. It makes sense and didn't know this was a thing, I will let this run for a few days and see what happens.

I will likely be fine now, it will just run as a single rail OCP now.

 

Interesting though as the OCP per rail should be 40A I believe, I could be wrong however..

 

Not sure what is going on with that.

[Jqwop]

Hey guys an update I had it on single rail all last night and it was working fine for the rest of the evening.

This morning I got up and turned my pc on and it sat on and idle for about an 20bmin and the turned off again. At this point I am unsure what to do.

Still waiting on a response back on my ticket with corsair.

If you guys have any other questions or suggestions please let me know.

Well, yeah something going on with that PSU.

 

As I said in the last post with that PSU I thought it was odd that it would work in single rail when the multi-rail OCP was plenty high enough.

 

I was hoping for the best.

 

Needs to be replaced, it is the old model Platinum AXI, not the new one. Could be relevant, I don't know.

I don't see how you could come to that conclusion.

 

The PC won't even POST.  That's not using much power.  Booting into Windows, that is.  Sounds like a motherboard issue.

But it works with his other PSU, the 750W.

 

Now if it wasn't for that, yeah maybe.

Oh... I missed that part.  Yeah... then I guess there's something funky with the PSU then.

That's what originally got my attention. 

[Jqwop]

I would like to clarify some things that I may not have been specific enough in the original post about.   

The system will boot with the 1200 W power supply and will stay stable for an intermittent amount of time. I can see gaps from days without issues to, like today, having it happen 4 times within the hour which is making this very annoying to resolve. I have worked with corsair to receive an rma for the power supply about 3 months ago and this power supply has the same issues as the last. I have since reopened a ticket with them and it has been escalated last week and I am hoping to get a response soon enough. I am honestly hoping that I won't have to replace this power supply because I only bought it in 2019 and had planned on using it for a while and its not exactly cheap.

As far as the reference to the not booting item this only happens after the power supply turns off from this "bug"(going to call it that because I still don't understand).

Other things that may be relevant I have my power supply facing so that the fan is inside the case but the side panels have been off for over a week with the issues remaining.  As i said earlier to my gpu there are 3 8 pins all separately connected to the power supply and to the cpu there are 2 separately connected cables as well. In the mean time I am going to have to get a different power supply so if @Ankersonyou would link me that list of known good ones that would be wonderful.

[Jqwop]

In advance I would like to thank you both for your help on this issue

Wonderful I have a Hx1000i on the way. Thanks for the link

[Jqwop]

Both great and terrible news. I remembered that the power supply has logging and I should have looked at it FIRST. I'm dumb I guess guys sorry. This power supply has a short in the  AX1200i GPU/CPU #8 that is dumping power into it. While idle it climbed from 0 amps to 48 Amps while connected to nothing. Thanks for the help guys sorry I wasted your time.
