Microserver Gen 8 appears dead after CPU upgrade

[James_Lee1]

After replacing the celeron in my working microserver with the e3 1265v2, I booted it up without a display and it seemed to power on fine. I then pressed the power switch and disconnected it from mains. Now when I plug it into mains the psu doesn't start and there is no sign of life (no power light, fans, etc). Wondering what could be the issue.

I have tried replacing the cmos, have tested the psu using a 24 pin jumper, left it unplugged overnight, replaced ram and cpu back to the oem parts.

Any help would be greatly appreciated.

Note: sometimes when I plug it into the mains the power indicator flashes amber momentarily.

The CPU model which you have installed does not get listed under the quickspecs or the Service maintenance guide:-

Please check the model of the CPU again. Please install compatible components and check.

System works after replacing the power supply. Not sure what went wrong with the original one as passed the jumper pin test.
