Question New PC turns on for a sec then off and then turn on normally after any hardware changes ?

[MariusThePaladin]

Hi, I've recently built a new pc (see spec below) and every time there's any hardware changes, even if it's just USB thumb drive being plugged in/unplugged, whenever I turn the computer on, it will turn off within a matter of seconds, then turn on again and run normally.
Is this normal for a modern PC ? Or did something got short horribly but the PC keeps on running anyways ?

Thanks for the answers

Spec:
Mobo: Gigabyte Z790 Aorus Master
CPU: i9-13900k
CPU cooler: Deepcool Ak620
VGA: Manli RTX4090 (it does the turn on-off-on thing even before the VGA is installed tho)
PSU: MSI MEG Ai1300P
Ram: Corsair Vengeance ddr5 5600 16gb x 4 sticks (XMP enabled)
Storage: kingston fury renegade 2tb x1 Samsung Evo 970 1tbx1 and a bunch of other external HDD/Thumb drives I switches all the time to install stuff
Case : Be Quiet Darkbase Pro 900 Rev.2 Comes with 3 Silent Wings 140mm fans
Additional Fans: Deepcool RF120 white 120mm x6
There's 2 RGB stripes that came with the case that I installed. The blue color is broken but the other color lights works fine.

This is hardware check and is normal operation.

If you don't want your PC to do the new hardware check every time, don't put the new hardware in every time prior to boot up.
