Question New and previously working PC not turning on after losing power once

[Muufti]

Just made a new PC in with the following parts: https://pcpartpicker.com/list/qfrLkJ.

Built the machine and got it to BIOS without issue. I got windows on a USB drive, plugged it in, and exited the BIOS. Nothing happened, and my monitor eventually turned itself off for lack of signal, so I tried to power the computer off. Front switch didn't turn it off, so I disconnected the power from the wall. Plugged the power back in and now it cannot be made to turn on at all - no fan spin or anything. PSU seems okay per the paperclip test and makes radiator fans spin up. Power button also isn't the problem, seeing as the screwdriver method didn't work. I worry that the board might be dead. I didn't think it should be able to brick after losing power one time, but I don't know what else the problem could be. Maybe it was just taking a long time to boot from the USB and I pulled power at the wrong time? Anything I could be missing, or any way to test if the board is bricked?

Breadboard the innards and try wot work with the bare minimum to get a display out using the iGPU(no discrete) on the platform. If that works, you can add the discrete GPU to the platform while breadboarded.
