Hello all!

I received my EVGA 3080 FTW3 Ultra Gaming yesterday in the mail and was so excited to install it. At install, I was using 1 daisy chain power cable and 1 single power cable. All 3 8-pin slots were plugged in and given power. I downloaded the latest drivers (456.71) and installed them as well. After getting everything squared away, I opened Path of Exile and started playing. After about 5 minutes of playing, my PC all of a sudden shut off and restarted by itself. No BSOD, no other warnings. I opened everything back up again on my PC and started PoE again. Same thing happened. PC restarted by itself. I ended up playing CoD:MW for a few minutes to see if it would do it again and it never did. I had the settings turned all the way up as well. Fast forward to later that evening and I was playing Phasmophobia with a few friends. No issues for quite a few rounds and then all of a sudden my PC restarted again.
 
That was all yesterday evening. I did some searching around and saw suggestions of plugging my PSU directly into the wall, using 3 single power cables for the GPU, as well as reseating the GPU. I did all of those this morning. I started PoE again this morning to see what would happen and my PC restarted as soon as I tried to teleport at a waypoint. I know I am not the only one with this issue, but I am so beyond frustrated with this. I am replacing my trusty EVGA 1080Ti FTW3 which I have had no issues with. I have used EVGA 750w PSUs in my previous builds and haven't encountered any other issues. My PC is all new parts as of just a couple months ago. I have checked Windows Event Log as well and I get multiple critical errors when my PC restarts itself (Event ID 41, Kernel-Power, Critical).
 
After reading through this thread, it does seem that the GA PSU could be the culprit. Though I just wanted to get some other opinions or suggestions as I know this is a fairly common issue. Please let me know if I can provide any other info.

I would try downclocking/undervolting the gpu to see if it keeps happening... if it remains stable its probably your psu.

Yeah, I think I will try that before looking at replacing the PSU. I have the new Precision X for the 30 series cards. Is downclocking something I can do in that program easily? I really don't have any experience with OCing.

Not sure about precision but it is pretty easy in Afterburner.
Not sure if i can post links here but here goes.

i would just try on the 800/900mv and see if it still reboots like that. As that should reduce power to 250 to 300 watts.

So I did a -50 MHz underclock in the Precision software and played PoE again. So far so good actually. I'm wondering if thats all I needed? I will look at upgrading to a 1000w PSU soon though.

Could very well be the case tbh.... i would guess it is your psu that is the issue.
Probably want to play a bit longer just to see if things remain stable.... if a -50mhz did it your psu might just be on the very edge of stability.
Hell i was going to undervolt my 3080 FTW once it gets here just because running it at 1900mhz on 925mv seems to reduce the power by almost 100 watt and makes the card run at 55/60c

Not like i need more power at 1440p.

Completely agree

God, I hope my 4-year-old EVGA 1600 G2 works.  
 
At the time total overkill now not so much. 

you have 900 more watts then you need

Hey guys,
 
Sorry had to step away from this for a bit. Gets frustrating :) Yes it seems its my PSU. I have no problem getting a new one. I can always sell the other. My current one is only 6 months old. I traced some of the issues with overclocking my i9 9900k. Was not stable at 5.0GHz for some reason. Changed it to 5.1GHz and its better. Kinda weird. Still getting some shutdowns, but not nearly as often. Only when im trying to push the card a little bit with 3DMark. My memory was rated for my motherboard so that was not the issue. I might get a 1000W just to be safe. I took at look at the recommendations Jankerson said worked. But I cant find ANY of those in stock. Thanks everyone who responded! Ill get her nailed down!
 
Cheers!

jankersonThe ones we know work are, so far:
 
EVGA G2, P2, T2;
 
Corsair RMX, RMI, HX, and HXI.

My 750GQ has been fine with my 3080 FTW3U, but I am looking to upgrade it. I actually bought an RM850x last week, but it died in 2 days and was a pain to work with the included cables with my case anyways.
 
Is there a condensed discussion that you know of anywhere about which PSUs are getting tripped by Ampere? I haven't been able to find one; just casual mentions about a few that do around the internet.
