The Radeon are not 115W … they are more in the Wall...
Also you have to consider Risers + Fans … You are really in the limit limit of the PSU
And also I hope your cards don't die soon... this is the worst 5700XT in terms of memory heat...
This is the reason why Asus make the TUF EVO... for the mistake of the memory disipator... I hope you try to make some mods in the backplate or something...
Thank for your reply.
The power supply is not the problem, because the GPU idle is - 30w.
Directly no boot with 10 GPUs. With 9 GPUs boot and work fine.
I haven't problem of temperture, the rest of the GPUs (9) work fine at 48C core and 82C memory whit fan at 50% and room temperture of 22-24C
