Ok, now we know you are on a fresh install, lets dig a little deeper

That PSU is a dual rail unit (basically 2 375w PSUs in one), this means you need to balance your load between the 2 rails. You were using the same PSU on the old system so you must have had it balanced in there. If you look at the spec sticker on your PSU you will see it has 12v1 and 12v2, you need one 8pin power to your GPU from each rail so it is getting the power it needs.



If you have multiple 8pin PCIe connectors on your PSU, swap one of them on the GPU, only one, leave the other as is. See if that helps.
