What component is missing on my Logicboard?

Hello,

I have a Mac mini 2014 which wont boot. When pushing the power button the fan spins for a fraction of a second and is off for 2-5 seconds. This cycle repeats endless. The USB-Ports have the same pattern of powered on and off. I tried another power supply without any change. When inspecting the Logicboard thoroughly i noticed a missing/broken component, but I cant find any details about it and I hope you can help me.

It is the very first component on the long edge of the Logicboard (purple rectangle)

Here is a closeup. The only markings I can recognize is a “As” written on it.

I hope you can help me with this

Best regards Simon
