I am in the final stages of assembling my first pc. I have got all the parts in and such. I have all the wires plugged in and such. I got to turn the PC on and everything starts up but the graphics card which is a Sapphire PULSE Radeon RX 6700 XT 12 GB Video Card. I know that it is only the graphics card, because all of the other fans spin up. I have tried mixing and matching which of the 4 pcie/CPU power supply ports with my 2 pcie cords and the 2 ports on the graphics card, none of which have worked. So if this is a super obvious easy to fix please do call me out for it. any help with issue would be greatly apricated.

What would happen if the psu didn’t provide enough wattage? Could that inhibit the gpu’s ability to power on initially

Probably not

#

Most likely it would just shut down the pc when the gpu is under load, e.g gaming

#

and draws power over the maximum OCP

Does it boot if you use the igpu?

random frost Does it boot if you use the igpu?

Due to my inexpereince, when I attempted to boot it on the igpu, I did not remove the GPU card, there fore from my understanding the IGPU was deactivated when I attempted to boot it so do not have a conclusive answer on that currently. I will attempt that once I am done with school today. in about 4 hours.

Turns that my schools It department got it working the here was the solution
Got the system going! Turns out that on this specfic motherboard, if you have 2 DIMMS they need to be installed in slots 2 and 4 (and not 1 and 3, which would actually be logical). Also, there is a 30-40 second wait while the system board goes through its start-up sequence, which displays nothing on the screen during that time. It'll feel like nothing is happening, but just give it half a minute or so and it should come to life.
