New PSU Issue

[theeighthbyte]

I recently purchased a new PSU. I installed it earlier and powered up my computer. Everything was working fine until I reached the login screen. The moment I got to the login screen, the computer immediately shut down and restarted. I have tried to access the login screen multiple times, but to no avail. I've even tried a system restore with Startup Repair, but that was also unsuccessful.

Does anyone know what the issue may be? Any help will be greatly appreciated.

Brand and model?

It's an Alpine 600W with a 120mm fan.

I don't think it's the PSU that's the problem. I just think that the OS doesn't like it.

That brand of PSU is very poor , I would never run any PC with it.

Hi
I had the exact same thing happen recently.
A windows update screwed up and I ended up having to reinstall windows.
The PSU may be a coincidence.
