Power Problem

[kopekci]

Hello,

OK, I am sorry in advance for my expression style.

When I have pressed power button of my tower, electricity comes to the PSU. But it seems like the voltage the PSU requires is under normal value. A sound comes, some fans turn, but HDDs do not turn ( do not make any noise)

Afterwards I switch off my PSU by the I/O button on the back side of the PSU, and switch on again, and next I press the power button of the tower again, and then everything works properly.

What should I suspect of doing this? Why does not the computer turn on in normal manner in every first attempt?

Thank so much for your help, at least for reading

What kind of PSU?

I had a used PSU do something similar, and was RMA'd for the cost of shipping.
