Question Pc Will reset

[PurplePenguinz73]

I have recently built a new pc with amd ryzen 9 5900x, an Asus Rtx 3090 oc, on a nzxt motherboard, with trident z royal ram 32gb
It runs fine for a little while and after a bit it just reboots itself and I can’t figure out why, I’ve done system checks and it says everything is fine, and temps are around 90 for cpu and 80 for gpu while streaming. Does anyone have any suggestions on what I can do to get it to stop resetting. It just black screens and I have to put my pin back in as if it just started

Do you know what BIOS version your motherboard is currently on?

I wasn’t able to update it to the 1.7 that they have posted on the website, I don’t know what it comes from the factory, I don’t think it did any updates when I started it. It’s at the p1.5 version

I do have custom cables from cable mods but they asked me for the specific psu to send the correct cables as well
