Hello guys,
I just put together a brand new PC, but after powering up the system the screen stays black. All the leds and fans and whistles are working as expected, but I can't see anything on the screen. I am fairly confident that all the cables are in place aswell. The card is in the PCIE_x16 slot. Might there be some incompatibility issue with the mobo and gfx card?

The complete system is:
ASUS 970 Pro Gaming/Aura mobo
Strix Radeon RX480
AMD FX9590 CPU
Corsair RM1000i PSU
4x8GB Corsair Vengeance RAM
500GB SSD
2TB HDD

Thank you in advance

UPDATE:

So I put in my old nvidia GTX670 and the same thing happened. The problem might be in me or the motherboard is faulty? I usually have more faith in tech than myself, so I might be missing something very simple...

UPDATE2:

I did a little research and on this thread
http://www.tomshardware.co.uk/answers/id-3312538/fx9370-asus-970-pro-gaming-aura.html
it seems like that mobo is a little weak for the CPU... can anyone give a more professional guess, if that might be the issue?

Thanks

The motherboard is the culprit. The mobo only supports CPU's with a TDP of 125W, here is the ASUS specifications page, at the top under the CPU section; "Supports CPU up to 125 W". The FX 9590 is a 220W CPU, so it will not function properly. You need a 990FX motherboard in order to handle that CPU.

Thanks, but before I close this thread I have one more question, which interests me. The parameter which (also) defines, wether the processor works with the mobo or not is the chipset? So for example my fx9590 has a AMD 990FX chipset, but my mobo only supports the 970 chipset. And even though both of these processor types fit in the AM3+ socket, the mobo doesn't recognize the (i think?) newer chipset type?

But for example if I would manage to update the mobo's bios, would that change a thing? If it would, I have the feeling the whole system would burn down eventually anyways.. :) but the theory behind it interest me.

Even though they are the same socket, the FX9590 is just that much more power hungry versus the 8000 cpus and below. That's why you need a 990FX board, because they are rated and built to handle high power usage CPU's. It's not that they won't fit, just that the motherboard cannot handle it.

The socket determines if the CPU will physically fit inside the board. The Chipset will determine if that CPU is fully compatible. A 970 chipset, can use a fx8320, as it is rated for a 125w tdp, but cannot use a fx9590 since it is a 220w CPU.
Now getting a 990FX chipset, you can use a fx8320 AND a fx9590. The chipset will determine the max CPU power draw.

Only update the bios if you find that there is a bios update that allows support. Some manufacturers have done this in the past, but I would not recommend it without researching first. Otherwise each motherboard has a specific chip set and cannot be altered.

Don't forget to choose me as a solution if I helped you out. :)
