Built a pc but it does not start

[Barrylim]

Hello i just built my own PC with the mainboard: ASUS ROG STRIX B550 GAMING WIFI and ryzen 9 5950x Processor. If i want to start the PC nothing happens, no fans are working. The only thing which is working is the RGB of the mainboard. I tried the following things:

-checked all components and cables for correct installation.

• started the pc with a screwdriver instead of the power button but nothing happened.
• made a bios flashback with an FAT32 and MBR-Partion table USB-Stick (Bios flashback seems to work because the green led blinks fast for 5 minutes) but the pc still does not start and no fans are working.

I made the bios flashback with the cpu and ram installed should I try it without?

Im happy for any help!

Does the PC show the motherboard manufacturers logo?
Is there a hard drive connected which has Windows installed?
Is the power supply a high enough wattage to supply full power?

What is the make and model for the Power Supply

I would dismantle it and reassemble everything on a table or the floor on a piece of cardboard.
Makes it a lot easier to swap components, check connections and avoid shorts.

no it doesnt show the logo, it does nothing except mainboard RGB lightning. The Pc is new so there is no windows installed. My power supply is the be quiet straight power 11 with 750Watt!
