HDPLEX build stops responding to "power on" all of a sudden

[spintje]

Hi guys!

I am the happy owner of one of the early NFC S4 minis, i have it equipped with Asus Z270i, HDPLEX 330w and a matching Dell 330w brick. Everything has been running smoothly for the past 2 years up until now, but for the past week i have been almost unable to turn my PC on by using the power button on the S4.

I can press it up 50 times before it turns on correctly. Sometimes i have to unplug the Dell brick, and that will work.

I have checked the pins on the MB and the connectors to the HDPLEX, everything is situated perfectly.

Does anyone have any clue what might be the cause of my issues all of a sudden?

Could this be a problem with the bulgin switch? Or is the culprit more likely to be found between the HDPLEX and the Dell brick? Any input would be greatly appreciated.

I was having trouble with my switch after a couple of years with mine, used another temporary switch to verify. Got a switch with a domed push button for my latest build much better positive action and a definitive click. Original was flat button very high spring force to get finger past the edge.
