PSU connection problem

[Iggy82]

Hi guys,

Yesterday my computer restarted several times without any obvious reason. This morning I tried to turn it on and it did not. After opening the case I realized that the problem is with my MB - CPU fan, keyboard, etc. were not on (while case fans were working).

After checking the tightness of the power supply connections on my MB, it showed some life and after some more efforts started normally. However, I did not find these connections lousy or something like this - I just pushed them a little bit, but they were sitting well.

The computer assembled 6 months ago. It was not opened during this time or moved somehow. It stands firmly. Now I recall that something similar happened several times before – it did not want to start, but after pressing power button again worked fine. Still never restarting or not starting after the second try.

PSU: Enermax Triathlor FC 650W
MB: Gigabyte H87-HD3 ATX Socket 1150

Is it dangerous to other components?
Any suggestions what to do next? I don't feel like the connection sits more firmly than before.

Thanks for your advices.

Enermax is not a bad brand and I don't want to buy a new one without knowing that it is really faulty.

I recently ran OCCT test and 12v test is on 7.01v value. Min is 7.06, max 6.96.

My question is if it could be caused by the bad connection to the motherboard? Is there any other software to check PSU? Also, voltage provided to different components?

BIOS indicates 12.3v for 12 volt rail
