For months I've been playing for months, I get a black screen and sound like when it runs aground nnnnnnnnnn nnnnnn, with an rx6700, and now with an rtx3060, the only thing left to do is hit the turn off or reset button... before ruling out other things, I ask, could it be the reason? psu?
Power card says minimum 650w and the 3060 600w
I have tried changing memories, hard drive, downloading drivers... tested temperatures
 
in doom eternal the rx6700 loads the game and when it goes to enter the menu... black screen
Not the 3060, but after a while it ends the same and happens in all the games after a while, black screen, stuck sound and with the rx6700 fans at full speed
 
could it be the psu? If it were the psu, it would have to be turned off, right? I don't know much but any power failure I would have to turn off completely... right?

thanks
hwmonitor gives playing the psu voltage
It was minimum 12.2v maximum 12.4v
the other voltages barely fluctuate

Operating Temperature 0° to 40° C ? 
I don't understand this very well, maximum 40ºc I can already assure that inside the PC there is more 40ºc, only the 3060 sets 85ºc and it is 4cm from the psu
rx6700 gave Windows Hardware Errors (WHEA) error
3060 events does not give any error at all

The latest 3060 card since I added a direct fan, it doesn't cause problems, I have to say that this 3060 comes from mining, it even has thermal paste scattered.... the fan at full speed only on the rx6700, the computer only has 18 months
sorry my english

This is what I got answered on a powertech forum
Is this possible? I need an explanation because it's scary...
¿¿??
Using this may have killed the Pulse GPU, EVGA make some good PSUs but they must be used for their intended purpose and White efficiency rated PSUs being among the weakest that there is should not be used anywhere near a gaming class GPU.

Anonly requires a 550W PSU whereas a Pulse requires a minimum of 650W as is stated  any PSU that you try must meet those specs + additionally be a minimum of Gold efficiency rated and from a proven brand such as the Corsair RM range, EVGA, Seasonic or Super Flower.

Your present PSU is so bad that it is rated as  so with this in mind it is advisable for you to get the Pulse GPU tested using an appropriate spec and quality of PSU in case the card has already been damaged.
 


PSU info: 

Nothing, we are still without problems, since the ambient temperature dropped, but when I have money, another source, no matter what...
