Is my PSU causing boot isses?

[nhess]

I recently went from an rx570 to a gtx 1660. Around the time of the change I started getting this issue when I try to boot the power button only works like 1 in 15 times or worse. Once it does boot there are no issues and everything works great. 

 

The aio will make some noise like its starting/light up and the gpu fans will spin, but it wont start the pc. Also when this happens the computer boots to the secondary monitor and requires a restart to get my dual monitors back. Does anyone have any idea what is going on? I check the front panel cables and they looked all plugged in. Also sometimes if I unplug my front usb cables the computer sometimes boots. I even got a seperate power switch and tried this and it has the same issue. I was also thinking the house may have trouble powering the PC? Its an old house with poor wiring, the microwave makes the lights flicker lol
