New build help please

Had a bit of a nightmare with my new build with a faulty PSU not helping.

After getting a replacement today everything powers up and the LED for CPU goes off / VGA goes off but it is stuck with the boot light on and I cannot get any display to appear on monitor so I am at a loss where to go next!

Specs are as follows

B450 tomahawk max
3600 Ryzan
Vengence 2x8gb 3600mhz
Gigabyte SSD 1TB
5700xt Red Devil
Corsair RM750x

Any help would be great

Is the graphics card powered with two separate cables? Known to be an issue with some AMD cards.

Assuming your display cable is connected to the graphics card not the motherboard.

Just got the GPU powered with the one cable atm

I did try it direct to the motherboard but never got any display either.

Did you try flashing to the latest bios version ?

Get two separate cables sorted out defo.

Motherboard ports won't ever work unless you get a G-series chip (APU)

Spot on with the 2 Cables being the issue.

Thanks for sorting it for me.

Seems to be a consistent issue with current AMD cards even on very solid power supplies.

Glad it's worked out
