My PC powered on and off for a few seconds repediatley, and now it wont do anything?

Hello, I built a PC with parts from micro center:

MSI B650-P PRO WiFi AMD AM5 ATX

AMD Ryzen 7 7700X

G.Skill Flare X5 Series 32GB (2 x 16GB)

Lian Li Lancool II MESH Performance Type C Tempered Glass

Seasonic USA Focus GX-850 (ATX3.0) 850 Watt

PowerColor AMD Radeon RX 6800 XT Red Dragon


I built the PC, turned it on, and the motherboard and the GPU would light up, and then turn off immediately, and it would repeat every 10 seconds. So I unplugged every connection to the PSU, confirmed that it worked, and replugged it in. I also reinstated the RAM. Now it doesn't turn on at all, and I'm not sure what else there is to do
