Hi dear users. I have had an problem today. My pc: 10850K stock 4800mhz stock Kraken X73 good temps 2x16 GB DDR4 GSKILL 3000mhz XMP Seasonic Tx-850 Ultra Titanium Gigabyte Rtx 3090 Gaming OC Aorus Z490 Pro Gaming 1 TB SSD I bought machine and plugged in march 2021. No single issue,no reboots,no shutdowns. I played all games for many hours,no issues. Today…i launched Metro Exodus and after cinematic part pc just shutdown. I rebooted again and its fine again. Happened when gpu load change from 0% to 99%. My question is. It was psu issue or maybe other hardware? I remember that when pc goes off ,pc case lights flickered once and monitor flickered. That not happens when i shutting down manually. i am running now game and no shutdowns. Happened today once. Also i have pc until march 2021 and thats like today never happened. Is psu going just bad,rma or what you recommend for me. Thank you PS:I am not german,very sorry for my language.
