New pc build won’t post/power on

[benjamin.lawit]

I have recently purchased parts for a new pc build, and the day came when I installed the final part, double checked the connections, plugged it in, flipped the power switch, and... nothing. Some LEDs on the motherboard light up, but that’s it. No fans spinning at all, no output to the monitor, no matter what cable port I use. I’ve already tried taking it apart and rebuilding it just to make sure I didn’t accidentally miss something about 5 times, and tried breadboarding. Anybody got any idea what’s going on?

Motherboard: Asus prime B350 plus
Processor: AMD Ryzen 5 1600
Power supply: Corsair CX Series 750 Watt
Graphics card: ASUS GeForce GTX 1060 6GB

Which LED's on the motherboard light up? They can tell you what's wrong--check the manual for how to decode.

Are you sure you have the front panel switch in the right spot?
