I recently upraded my gpu from a 1060 3gb to a 2070 super. I got a psu from a friend because my psu didn't have the right pins. After I installed the gpu, it ran fine at the begin. But when I started playing fortnite (please don't blame me, I still play this game because my friends do;)) it suddenly just powered off. I got the message "power supply surge detected during the previous power on. Asus anti-surge was triggered to protect system from unstable power supply unit". I think this is because the psu i got from my friend is more than 2 years old but i just wanted to check it here.
My specs are:
CPU: i7 4770
GPU: gtx 2070 super
RAM: 16gb ddr3 kingston
MB: Asus h81m-plus
PSU: ocz700sxs 700 watt (this is on the side of the psu)
I think because the psu is old it doesnt deliver enough power. But I'm not sure. If you think this is the case. How much wattage do you think i need? Also when I ran the system with my old 1060 3gb, it worked perfectly fine, but as soon as i installed the 2070 super it crashed. I checked the pins that are connected to the MB and they were all good. So i ran it again and it crashed again when i started playing games.
please help me with this I really dont know what else it could be.
