Aurora R7, not powering on when 6 pin power is plugged in for GPU
Hello,
i have a proplem with my computer. I had a power surge the other day and my computer was not turning on at all. Changed the psu, at first it was not doing anything. I then unplugged all unnecessary peripherals (keyboard, mouse, gpu…) reseated ram, reset CMOS, and it powered on. Was very happy at that point! But…I then plugged back all peripherals, except 8/4 pins pcie connector for the gpu all is good at that point. But when I plug in the 8/4 pins pcie connector to the motherboard for gpu my computer won’t even budge, no light, no sound…no power at all…
Anyone has a suggestion at that point? Is my gpu dead and that makes my computer not even want to start?
New psu is a 650W got on HDD and one nvme, and gpu is a 1050ti. CPU is a 8700.
Thanks

@VieuxWolf The GPU_POWER connector on the R7 motherboard uses an EPS 8-pin cable, not PCIe.
It looks like that Corsair PSU has only 1 EPS cable and 1 PCIe cable. What cable are you using to connect to GPU_POWER header? Consider a fully modular PSU next time.

What PSU did you get? That 8 PIN on the motherboard might not be a standard PIN, but a custom PIN.

My GPU 1050ti doesn’t have any connector socket, it take his power from the GPU_PWR connector on the mobo from my understanding. So if I understand correctly, the wire I am using (pcie 6/8 pins) is not the right one? I should use the same type of connector that is powering cpu? But I don’t have an extra one…makes sense why it is not loving it. I will see if I can return the psu and exchange for a fully modular.
Will keep this thread updated. Can you just confirm the type of wire/connector I need to plug in the mobo socket GPU_PWR please?
Thanks a lot!

Is there a way to test my old PSU. There is a button with a green led. When I plug it to the wall and press the button the led does not light, fan is not spinning. Is it dead for sure? Is there a way to jump pins on the 24 pins cable to make the fan spin and see if it is still alive?

@VieuxWolf confirming that the connector for the motherboard header GPU_POWER is EPS 8-pin, the same type cable used for CPU power. So you will need a PSU that has at least 2 EPS 8-pin cables, and at least 1 of those should be EPS 8-pin (4+4).

@ProfessorW00d
It is confirmed…I only have a 4+4 eps connector from the new psu…
