Again the power draw from the 300 series is greater than advertised as it seems.

Possibly, or it may be a driver issue or a PSU issue or a faulty card issue or a combination of any of these or other factors. We do not know yet.

Another lie found by consumers🤔
Thank you Nvidia 🙄

You're claiming NVidia did this on purpose? - another lie put forward by resident AMD fan and Intel/NVidia basher Atfrico. What a surprise. One could then say the same about almost every failed driver update AMD issues.. lol.

So replaced my Seasonic Focus plus 750W with a Corsair RMX 850W. My computer and card are now running smoothly and even put it through OCCT power tests for sanity. So yes can confirm personally what Jankerson said and some PSU lines don't seem to be able to handle this card. Best of luck to everyone else with this problem.

It just seems to be certain models.
 
Like my Prime Ultra Ti 750W (750TR) can handle it ( I tested it yesterday) while others had the Prime Non Ultra 750W Prime Ti (750TD) and they shut down.
 
So it has really been interesting to say the least.
 
 

Forgive me I just joined this chat - are non of ya'll undervolting / downclocking your cards?

stay with me here (I could be way out of line for saying this but whatever).
 
lets say these FTW cards have great heatsinks (the best heatsinks folks) so the card keeps trying to boost higher and higher.
 
problem is the card boosts into the higher clock speeds (Danger Zone!) that was crashing many other 3080 cards prior to the new drivers.
 
so have any of you tried undervolting your FTW cards and turning the speed down to 1850 or so in afterburner?
 
unless im wrong I think these ampere processors dont like being anywhere over 2000 on a regular basis.
 
the undervolting would solve ya'lls problem with the PSU inadequacy concerns at the same time.
 
sorry if this has been covered Ive been skimming since page 5.

I've built several rigs at my local pc shop with the 3080 and a 750 watt psu. (New psu's of course)  you can definitely run a 3080 on a 750 that has strong 12v rails with no issues ... but if your psu is aging ...the power draw on the 3080 can be too much for old caps to handle...

MOST of the ones have PSUs that have a history of issues with transient power problems.
 
Corsair actually tested all of their line, Gold and above and all of them work fine except for the SF750....
 
 
 
 
 
 

Sooo, am I going to be ok with my Supernova 750 G3 orrr?

Yes, I would think so, saw someone here running one on a G3...

Yes they will, absolutely will run on a 750W quality PSU.
 
As long as the model doesn't have issues with Transient Power spikes, and that is only certain models.
