Delay after pressing the power button

[lafrente]

There's a very noticeable (more than half a second) delay until the computer starts after I press the power button. I am really not sure if I had this before. It might have just got worse. I press the button, take my finger away and its still all black, only after a moment the power button led light up and the system starts running. (That's no bios check or anything, it takes more than half a sec for any action at all to happen.)

 

I just shut it down and powered it up after 5 seconds just to test. This way I get zero delay.

 

Is this a PSU issue? Or is this even an issue? PSU is capable of more than 2x what my system needs.

Are you turning the PSU off from the back of the PSU prior to seeing this "delay"?

 

Or do you leave your PSU on and still see this delay when you press the power button?

Hi, I always keep the flick in on position. I see the delay even when I wait a minute in shut down state.

 

Disabling ERP ready in BIOS fixed it.

Really?

 

What PSU is this?  And what motherboard?

Yep, I tested it a few times to make sure. I can update the topic if anything changes but I don't think so because its starts in an instant now.

Weird.   That PSU is definitely ErP compliant.

By default ERP was disabled on the mobo. I enabled ERP was because PC would turn on by itself after a power outage despite configuring every related setting to stay off.

 

My only theory is maybe it takes a while to charge up all the capacitors after pressing the power button since they can't draw anything from the mobo in off state? And when I disable ERP mobo keeps the caps full for immediate power on.
