I am on my first build. I have a Ryzen 5 2600, b450 aorus WiFi gaming mobo, 16g ram, and a gtx 1650 super. I built this a couple weeks ago and since then everything has been running perfect. Up until last night when I noticed that any time I tried to open a game or do anything that requires gpu load the fans on the gpu would @rev” all the way up and my computer would go to a blank screen before it restarting or me having to restart it myself. I’ve done just about everything. Disassembled and reassembled, re-applied new thermal on my cpu. Can anyone please point me in the right direction!? I’m out of ideas. IMG_0371.MOV

So I’m new to pc gaming and just built my first tower. I currently have a gigabyte aorus mobo, Ryzen 5 2600, gtx 1650 super. My question is; I’m planning on upgrading to an RTX 2060 super but I don’t seem to have an 8 pin coming from my psu. Is their an adapter or can someone help me figure out what kind of psu I need to buy in order to accommodate said gpu? Any input is greatly appreciated.
