I have the exact same issue, and I have a very similar power supply to yours. If someone could help me as well, that would be great. Also, you need to make sure that the power supply you borrowed is enough to handle the load.
Hi, I built my pc as of last year near the end of 2020, and ever since I finished the building process, I have been having issues with games such as Fortnite and COD Warzone. I am pretty confident this issue relates to my power supply and not overheating because sometimes my computer restarts immediately at launch. I also downloaded an app called Core Temp, and my CPU temperate is staying within the range of 65-70 degrees celsius before it even restarts. Some info you may need to know is that I had a Ryzen 5 5600x Vermeer CPU which was later upgraded to a Ryzen 7 5800x, and we made sure to apply more thermal paste when upgrading. Additionally, I used to have a 1660 super and that was later upgraded to a 3060ti. I also had this ongoing issue with my 1660 super, but not as much as I am having it with my 3060ti. That is the reason I am thinking it is a power supply issue. I also did verify checks for Fortnite, and scan and repair checks for COD, and have also done reinstallations many many times. In some cases, reinstallations works for Fortnite, but no hope for COD. Also, sometimes when I cap my fps high, my pc automatically restarts which also makes me think its a power supply issue. I don't think it is overheating as I said before because in some cases, it restarts immediately during launch. As for Valorant, everything works fine and I am able to play. This has been an issue for such a long time and it is very frustrating, and I am considering replacing the power supply and giving a try on that. But before I do that, I wanted to create a forum and see what others say.
