Discussion Dan A4 - power issue

[Shaytanya]

Hi team

About 18 months ago, I built my second build in a Dan A4. Last week, it appears that there is no power getting to the Mobo (asus z490 i gaming) as the RGB isn’t lighting up and the pc isn’t turning on.
I have checked the power cable and also the cable going into the PSU and am reasonably confident that there is power going into the case and into the PSU, but it appears that nothing is getting further

does anyone have ideas of how to fix this or if there is a way to test the PSU (Corsair 750) or to see if it could be one of the cables (pslate customs) that is at fault.
ideally I don’t want to take the whole pc apart, but more than willing to if I need to.

thanks in advance.

You can start the PSU with a short cable from pin to pin in the ATX connector. Tutorials can be found with a quick search. If the PSU starts the mainboard or the powr switch is the culprit. You can bridge the power switch oins with a screwdriver to startup or your board has a dedicated power switch onboard.
