System Details

Ryzen 5 3600 

Asus ROG Strix B450-F Gaming 

G Skill Trident Z Neo 2x8gb 3600 ram

Crucial 500gb NVME SSD

WD Black 1tb 7200

Kraken X63 AIO

Zotac 2070 Super Twin Fan

 

Issue

The computer will not post

No diagnostic LEDs come on

All fans, AIO, and RBG are working

The ROG Strix rbg logo is working

The fans on the 2070 do not turn and the led on the card does not turn on

I cannot access the BIOS so I am not sure what version it is

 

Troubleshooting Steps Taken

Re-seated the RAM, GPU, All Power Connectors, and CPU

Tried a different GPU, GTX 960

Cleared CMOS

 

This is my first build and I am stuck.  I am not sure if the RAM is causing the issue but I am at a loss.  

 

I will go pick up some 3200 mhz ram tomorrow to see if that corrects the issue.  The board was just purchased and the guy at Micro Center said I shouldn't have to flash the BIOS. 

 

Thanks in advance for your help.

might need a bios update as not all b450 boards support 3rd gen ryzen out of the box

Sounds like you need bios update. Older mobos don’t always support 3rd gen Ryzen out of the box. Can you get hold of any 2nd or 1st gen Ryzen cpu just to do that?

That MOBO only supports up to 3200mhz, that might be the problem. Also have you tried putting the GPU in the top lane?

 

EDIT: What PSU do you use? Maybe it's too weak.

Thanks for the reply.  

 

I am going to purchase some 3200 speed ram today and see if that does the trick.

As for the Power Supply, I am using a 650w 80+ Gold Thermaltake unit.

According to the ASUS website it should support 3rd gen out of the box.

This may seem stupid, but check your cpu power connector is plugged in at the mobo and psu. As that powers the diagnostic lights.
