Hello, I have during the last 2-3 weeks had problems with my computer sometimes not starting and instead only my gpu lighting up and its fans going. I looked around and since it would sometimes happen after more than 12 hours after I last turned it off that it wasnt overheating (I also monitored the temps and it is usually at around 60-65 degrees) and it was instead my psu that were the problem.

I recently bought a new psu and now it just wont start at all anymore, with the gpu lighting up för about one second whenever I try to start it and nothing else happening. I have double checked and believe all cables are correctly put, I also have same cables to my hardrives from my last psu, which I doubt would cause this?

My components are:
GPU: MSI gtx 1060 gaming
CPU: i7-7700k
Motherboard: asus rog strix z270h
new PSU: Seasonic Focus plus 850w gold
