First Graphic Card..First Problem

[Aliotho]

Hi all,

 

i recently bought my first graphic card, an ASUS GTX 1660 Super OC but i immediatly had some problems.

 

I connected it to the PSU, a Corsair RM550x with an 8 pin connector (i got the connector from amazon, so it was no the original one of the psu) and then installed the card in the PCI-E connector of the motherboard an MSI H170a with an Intel i7 6700.

I noticed that there was a white led shining on the graphic card, so i supposed that the power connection was ok, but it became red while the pc was turning on.

Then the screen saying to connect the power supply to the GPU. Turning off the pc, the led become white again.

I tried to update bios and restart numerous times without any success.

 

Do you think that the problem is the cable or there is something that im not considering?

I thank you in advance for any kind of suggestion. As i said for me it's the first try and everything might be helpful :)!

Try it with another PSU or try reconnecting the PCIE cables.

Modular power supplies do not work with just any cable, you need to buy a cable that is guaranteed compatible with the power supply. Here is a diagram for the power supplies from corsair that can share cables:
