Question Help, pc clicks and flickers multiple times before running

[Marcodude04]

So my pc turns on in a weird way… (video will be attached) it’ll click a 3, or 4 times whilst the rgb flickers before it boots, wondering if it’s a failing psu or not. I jsut upgraded my motherboard and aio, so wondering if I also did something wrong, when the pc is on temps are comfortable and it runs stable. Side note I have my case fans not using the regular daisy chain controller but rather have the pwm headers plugged into the mother board ( headers are 3 pin) motherboard has 4 prongs and the extra rgb daisy plugged into my aio daisy chain… wondering if that could be causing the problem as I’ve removed the stock controller which had a sata power source

attached is a link where you can see what I mean,

everything is plugged in exactly as to mobo instructions and aio except the rgb for case fans. It never did this before the upgrade!! Also fairly sure as I was told by people at Canada computers that my psu wattage was more than sufficient!

You use extensions? If so test without those.

Also do make sure all power connectors are secure in their sockets at both sides, so psu side as well.

Maybe, but now you have different motherboard and so it can do things differently now then before. I watched your video and I don't see anything wrong with how it starts.
