Not sure is it because I use the same pcie cable for 8 + 6.
I tried seperate it then it works...
then later on when i install amd adreline screen turn black after 10 min waiting still black.. force shutdown..
turn it on again then it works..
Since 2 pcie cable seperate i do another cable management...
once done no gpu signal again... then force shutdown...
Then now back to normal..
System i5 13400 + b760m wifi 16gb ddr5, kc3000 ssd, viva gold 750w
Then try my Genshin game on this system, setting auto selected high..
CPU temperature good, min 34C high 59C
But GPU seems high? I not sure which part should i focus on.
using Antec DP 502 Flux
Should i worry on this temperature?

Try ROG Realbench and Furmark for 1 hr at least. Monitor with HWINFO, you shd be maxing out at 230W TDP (right now I see its 155W). Ur fan speed is 971rpm so it looks to be too low? Can try upping the fan curve with Afterburner.
