I've just changed my GPU to from a Gtx 970 to a radeon rx Vega 64. Now when I plug the GPU into the PSU my PC will not boot even though there is power to the motherboard. If I unplug the PSU from my GPU, it will boot up and will also do so with my old GPU. I think it might be down to a lack of power but unsure. Any help will be greatly appreciated.
My build is as follows. Intel i7-5820k Asus x-99/USB 3.0 16GB DDR4 RAM Sapphire radeon rx Vega 64 nitro+ Corsair H115i AIO cooler Corsair command pro with 3 120 case fans Samsung 840 evo SSD Corsair CX850M PSU Thanks, Adam. |

| possibility you have fried the GPU causing a internal short this will give you the exact fault you have just explained. especially if it works with the old one in and also if its unplugged |

| When I unplug the GPU from the PSU and turn my PC on the side lights on the GPU turn on but does nothing else because it has no power other than what the MB is supplying it. |

| if you take the new GPU out of the equation and the pc works fine but you then fit it and the pc no longer works its the GPU at fault |

Josh_ wrote if you take the new GPU out of the equation and the pc works fine but you then fit it and the pc no longer works its the GPU at fault The website recommends a 850w psu which is what I have, but I'm not sure if its not quite enough with everything else I have in my case? |

| I've just looked on the manufacturer's website and it states the GPU power consumption is 750w. With me only having an extra 100w capacity on top of that, could that be the issue? |

Vega is a very power hungry card. Though i wouldn't rule it out. Your system as is draws a good bit of power. It would still boot; 750w is the card's peak wattage if i remember properly.
Have you tried any of your other PCIe slots? |
