Help, Newly built pc lights up but does not boot.

[cxrlos03]

Hello, I have built (or attempted) to build my first pc. I have made sure I followed instructions and plugged every cable in the correct socket. Everything is up to standards when it comes to a built pc. When I tried booting it all the mobo rgbs came on and the mouse I was using lit up. Although there was no video, no fans were spinning including the psu fan and there was an orange LED on the motherboard which I cannot find the reasoning for this in the manual. Can you help me figure out the issue?

Specs:
Case: CM masterbox lite 5
APU: Ryzen 3 2200g
RAM: DDR4 Corsair Vengeance 3000mhz 4x2
MOBO: ASUS ROG STRIX b350-f gaming
PSU: thermaltake tr2 s series 500w 80+
I imagine it’s a bad psu, it was purchased from amazon and the return date is expired.

Can you please find the EXACT SKU (model number) of your RAM? Although your PSU isn't the highest quality, the fact that it turns on period makes me wonder. Where on the motherboard was the LED? Usually, these are for troubleshooting devices, and if it's constantly on, it can help us find the issue in your system.
