Monitor doesnt work after directly connecting to graphic card

[bjjlastgrip]

I have this mother board:

PRIME H510-A 12000 DDR4 ASUS

This is the graphics card:

Geforce RTX3050 Gaming OC 8GB GIGABYTE

If I insert the hdmi cable to the mother board everything works, but when I insert it to the graphics card, it beeps a few times and then stops.

The monitor doesnt receive any signal, it is black.

The graphics card is connected correctly, I checked it several times and it is lit.

The only thing that isnt connected to the graphics card is the power supply cable. But as I read the instructions, that connectional is optional.

What instructions is that ? The Gigabyte specs here says that it needs - 8 pin*1

That is a big add on GPU and I strongly suspect that there is not enough power going to the PCI-E slot to get the card working, RGB lights yes but not the fane etc, you should also have a minimum of a Gold efficiency 450/500W PSU from either Corsair, EVGA or Seasonic.

This is my power supply:

SMART RGB 80+ 600W Thermal Take.

But I cant find that cable in the console. The power supply is isolated in the box. Do I have to find it and then get it inside the console?

SMART RGB 80+ 600W Thermal Take.

That PSU should not be used anywhere near a PC that has anything more than the most basic of add on GPU, it is not even Bronze efficiency rated, is labelled as 600W but can only produce 504W and even that figure is questionable, you need a minimum of a Gold efficiency rated PSU from either Corsair, EVGA or Seasonic.

Fwiw, your PSU is rated as Tier D • Recommended only for very cheap, iGPU systems

I think i was deceived about the PSU. I did manage to connect the power supply to the graphics card. It works. Now I am installing the drivers.

Whatever you do, get a better PSU asap, the junk that have may work short term but all the while that you are using it you will be damaging your other hardware, the GPU being the most power hungry tends to suffer first and the most.
