I finally got the hands on Nvida 3080 FE card.
When I was installing, I come to realization I may be very close to 12 volt rail requirement.
I have EVGA 500 B it has a 40 Amp / 480 watts dedicated to it.
I used the MSI After burnner to see what is the maximum power draw is, which was 370 watts; when I run userbenhmark.
I am not sure how accurate the sensor is.
I think I am coming very close to it.
When GPU is peaking its pwr draw to max, I only have 110 watts is left.
I have to take in place my Ryzen 2700 CPU has 65 TDP +
Which left me with 45 watts to spare for my AIO and HDD and 3 PWN fan and 120 AIO.
So that being said, I am due for higher watts P/S.
I am thinking about getting an EVGA Supernova 750 G+, 80 Plus Gold 750W
I thought I will ask other fellow member who owns the RTX 3080, what they are doing it ?
One side I don't O.C with Over voltage.
I don't mind Auto O.C./ Turbo and I don't mind allowing PWR limit to higher.
However no manual over dial the voltage.
