TC-1770-UR11 inadequate power by design or defect?power supply stickers say that its 300 watt

I have a two-month-old TC-1770-UR11. The power supply stickers say that it is a 300 watt supply. Everything works excellently when the computer is "as shipped". But, when I try to add anything that draws more power (NVME drive in PCIE adapter or case fan connected to the case fan pins on the motherboard) the system will not boot. When starting, it beeps once and displays the "Press <del> to enter BIOS, Press <F10> to display boot menu." prompt. It hangs there and does not respond to any keyboard or mouse input. If I power-cycle it, it repeats the same process until I remove the load. Then it works fine again.

I called Acer support but the tech went into a rant about installing RAM with the wrong speed and I couldn't get him out of that rut.

Do any of you smart people know how I should proceed?

They never state that the slots are GPU only in any documentation I've seen, but we've seen several users over the years who have run into it as a hurdle. IIRC always when they are trying to put an x4 or x8 card into the x16 slot. I believe the BIOS looks to see if the slot is populated and disables the onboard GPU if there is a card there, even if the card isn't a GPU.
