RX 5700 XT not detected

So I attempted to try out my new Gigabyte Radeon RX 5700 XT Gaming OC 8G to see if it's all fine and stuff but when I turn my computer on all that turns on is the RGB logo but the fans don't spin and there's no video output. I was able to get video output from my motherboard and saw that Windows couldn't recognise the GPU.

 

I'm not sure what the problem might be but I was trying to run it on a EVGA 450B 450 Watts Bronze PSU so might that have been the problem? I did also try to put the 6+2-pin connectors upside down accidentally but I don't think that might have caused any damage?

Your power supply only provides 450w total to power up the rig which is not enough for the gpu because the gpu alone will need on average 550w. Thats why it cannot display the graphics card because it is not getting the full power it needs.

Kinda thinking the same, I just thought that it would atleast output a video and turn off the computer or something when it needed to use more power (aka when its not on idle). Atleast I get life from it such as the RGB light and the GPU fans do twitch one when I turned the computer off. I just hope its not the worst case scenario of the GPU not working.

yea pretty much the power supply doesnt have enough power to run the gpu

the gpu is probably working just fine IF it has enough wattage going through it even at idle the card still needs that wattage cuz the power supply is providing power to all the components and theres not enough to run the gpu at idle the card is working fine tho

Not true at all. I have my 5700 XT overclocked and overvolted, and my entire system + monitor doesn't even draw 450w at the wall under synthetic stress loads.

Putting them in upside down would've been nearly impossible. It wouldn't've latched, and you would've had to effectively destroy the pins to do it. If you actually managed to get it on upside down, then that would most likely be the the cause. (because it DEFINITELY would've caused damage)

They only went in slightly and I was wondering why they wouldn't go any further so I don't think theres any damage on that part. So could the GPU be the problem or the PSU?

It's possible that the PSU has a broken wire, or something else damaged. It's also possible the GPU is damaged in some way. If you can, try the card in another known good system. No need to install any drivers for it, just get it to turn on. It shouldn't draw more than 100w for a Windows startup. If it works in the other system then the PSU is the problem, if not, then the GPU is the problem.

My older GPU which needs a six pin connector works fine so I guess it's not a damaged cable. I have no other pc to test it on but the card does turn on as the RGB works but it's just not detected and not outputting anything.

Actually I just noticed that if I have a 8 pin connector plugged into the 8 pin slot then the other 6 pin slot in the gpu has a white light and when I plugged it into the 6 slot then the 8 pin lighted up. Could that mean the gpu needs both 8 pin and 6 pin slots connected to work? I only have a single 6+2 pin connector.

Here's a image to show what I mean, if I plug it into the left then the right lights up but when I plug it into the right then the left lights up.

Yes it needs both at minimum.

Oh ok, I hope thats the reason why it's acting like this.

Yeah, you're leaving off about 2/3 of the power if you don't have the 8-pin plugged in, and 1/3 of the power without the 6-pin. It needs both.
