Specs:
MB: MSi b350 Tomahawk
GPU: MSi 1050 ti
PSU: Corsair CX550M
HDD: Seagate 1tb
CPU: Ryzen 5 1500x
RAM: 1x8gb Corsair Vengeance
Chassis: Deepcool Tesserect

So I just put it all together, and when I plug it in, the power led on the chassis turns on but when trying to boot up, nothing happens. Not even the fans connected directly to the psu are turning on. Tried taking it all apart and putting it back together, and still nothing. I am assuming that the psu has some sort of issue, but I wanted to check here if anyone has any ideas, anything already known to the community. Any help is appreciated, thank you!
