So I've just upgraded my old custom built Pc (worked 100% fine never had an issue) I changed case and gpu from an old vantage mid case to a new cullinan mid case, gpu was an older amd sapphire 7950 and upgraded to an msi 1080p, wired all up correctly but when i turn the pc on it turns on for 1 seccond (cpu, gpu and case fans working) and then turns off and then after about 2 more seconds will attempt to turn on again and then will turn off again after 1 second and the pc will repeat this until I turn the psu switch off.
thinking that the gpu was then taking up too much power I decided to disconnect and take this out however again the problem persists!
I Then decided to try another case to see if it was the power cables of the new case causing the problem and the same issue persists
I then took the cpu out and all the pins are in good order
Have narrowed it down to either be the psu or motherboard but has Any one got any ideas or had the issue before?
PSU is a corsair 850
Look forward to hearing replies
Thanks
Chris
