Question My PC turns on when PSU is switched on ?

[Summer101]

Hi,

My PC turns on as soon as I switch on my PSU even though I have yet to press power on button.

I don't necessarily mind it, but will there be any problem in the long run?

Thank You!

What's happening exactly. It's booting to Windows?

Yeah, it fully boots to Window.
At first I thought it was because of PSU since my old one was pretty poor quality, but even after switching to a new PSU it still does the same thing. Not sure if this is good or bad.

Is there something wrong with your power button itself? Have you checked the power switch is wired up correctly to the motherboard?

Disconnect the powerswitch from the headers on the motherboard.

What's the brand and model of the case, motherboard and PSU?

Mhm, it shouldn't be since the original OEM PSU won't auto boot when turned on.

OK. Dell 7020 is proprietary crap with 12vO PSU. Do you have the correct 24p to 8p adapter?

I use an 24pin to 8pin adapter. But not quite sure what you mean by correct adapter?

But not quite sure what you mean by correct adapter?

With transformer for 12vSB to 5vSB.

With transformer for 12vSB to 5vSB.

I will try to find the page where I brought it from. But will it be a hazard if I'm using the wrong transformer/adapter?

Edit:
I believe this was the adapter: https://www.amazon.co.uk/Optiplex-P...d=1663145995&sprefix=24pin+to+,aps,367&sr=8-4
