I just finished building a new pc but when connect my vega 64 gpu, the monitor shows no signal and does not even load bios. All the fans turn on and lights turn on (on all the pc hardware as well as peripherals(mous & keyboard)). However, when I conenct my old gpu, a gtx 960, the computer boots and works perfectly fine. I'm not sure where the error is, I have tested the vega 64 in my old system and it works in my old system as well but not on this new one. I'm not sure what the problem is
Specifications:
CPU: Ryzen 7 2700x
Mobo: x470 Asrock Taichi Ultimate
Cooler: NZXT kraken x52
Ram (g.skill trident 16gb(2x8gb) 3000mhz sticks on the way): 18gb (2 x 8 gb)Hyperx fury 2666 mhz
PSU: Corsair RM750x white version
Case: NZXT h440 (white/black) (3 included fans in the front and 1 in the back)
GPU: Vega 64 (ROG strix 8gb oc)

If anyone needs more information, ask and I'm happy to answer, Thank you for taking your time to help me!

I flashed the Bios to the newest version but that didn't seem to solve the problem. Thanks though

I'd say double-check all of the connections and double-check the wiring, make sure nothing is lose. If that doesn't work, give the vendor a call. Something fishy going on here. Are you sure the PSU is able to handle the new GPU along with all of the other components?

I'm pretty sure 750w is enough for all my components, I have checked mutliple times on psu calculators and my system comes up to roughly 500-600 w. As for rechecking all the connections I have already doen that once but I'll do it again just in case. Thanks for the response!
