PC doesn't power on.

[Jamie Spensley]

My friend just finished building an AMD cpu build with a Nvidia gpu and the pc doesn't turn on. No fans or lights power on at all. The little gpu light shows when the psu is powered on. He has tried different combinations on the front panel connectors and has done the exact method shown in the motherboard manual but still no power. He has tried different outlets around his house but still no power.

 

Any ideas on what is happening?

 

Build:

Asrock b450 pro4 motherboard

AMD 2600 cpu

Asus GTX 1060 6gb dual gpu

Cooler Master MasterWatt Lite 230V 400W ATX psu

Corsair Hydro Series H100x 240mm PWM Liquid CPU Cooler

Cooler Master h500m case

2tb Seagate baracuda hdd (boot drive + games drive)

What RAM do you have? That seems to be the achilles heel of Ryzen builds. Also try following the steps here first:

Actually.. are you sure the Power button is plugged in the right header and not something like the reset header? Many of us here have done that before.

Make sure the power button works. You can also use a screwdriver or keys to short the power pins on the mobo which would turn it on.

If that doesn't work: Make sure the PSU is switched on and heck if the PSU is making a clicking noise. If it is, it's DOA and needs to get RMAed. You should also short the ON pin and GND. If it turns on it's fine.

Make sure the CPU power and 24 pin are fully plugged in

Thanks, I'll get my friend to try some of these things out. He said he tried many combinations of the front panel connectors so I don't think that's the problem. PSU works and shows it is working by the lights. Also, the only new parts are the mobo and cpu. Every other part has been tested on other builds and worked. This is the ram, psu, gpu, fans and cooler.
