Hi so recently I finished my first pc build. Everything runs fine except for when I try to play any games on steam, or fortnite, etc. Here is a link to a video I made showing what happened. Btw my driver's are all fully up to date. https://youtu.be/tpqV3h8N4C0
My psu can be found here: Seasonic S12II 620 BRONZE, SS-620GB Power Supply https://www.amazon.com/dp/B003BIEOCI/ref=cm_sw_r_cp_apa_i_LmD4AbB26F6DP. My GPU I bought used about 2 months ago. I am able to access YouTube btw, just games don't function.
I would say it is really bad idea to buy used video card right now. The crypto miners have ran these thing hard 24x7 in past 6 months, and they are probably looking to dump them now and cut their losses. Buying used puts you at a significant risk of getting one that is failing in their mining rig.
