Question Installed RTX 4060 and now pc wont boot

[webguynz]

After some help please.
I recently bought a GPU for my sons gaming machine and after installing it the machine now wont boot, the light on the CPU cooler flashes for a split second when i hit the power button and then nothing happens.
The card I bought was this one https://www.pbtech.co.nz/product/VGAMSI440600/MSI-NVIDIA-GeForce-RTX-4060-VENTUS-2X-BLACK-8G-OC and his motherboard is an Asus Prime B550M-A Wifi II which after some investigating before purchasing I figured was compatible.
The machine has a 650W PSU which as far as I am aware should be sufficient.

Any help much appreciated as I now have a very sad young man!

supposed wattage alone doesn't tell if a particular unit can handle a job
