For now I have three questions (for Skybuck's Super PC 2023 build):
1. The CPU power, on the motherboard there are two headers/ports, two 2x8 power slots. Must both be connected with power cables ? The manual doesn't really say. Is there such a thing as delivering too much power to the CPU ?! ;)
2. The CPU pins ? I thought the pins were on the motherboard socket, but I did not see them. Since I have not unpacked the processor yet, maybe the typical golden pins are on the CPU itself ? and I am confused with threadripper ?
3. The BIOS flashback feature of the motherboard does it need RAM chips mounted to operate/work ? (It's supposed to be able to work without a CPU, but what about RAM chips, besides from power, does it need anything else ? Also a more detailed question perhaps, which power cables must be connected to operate BIOS flashback successfull ?
(Later I will augment this post with links to videos inspecting/pondering question 1 and question 2, question 3 will be a bit more complex and will require a second computer, usb stick, some kind of fat system and a bios file renamed to something peculiar/particular ;)
Bye for now,
Skybuck.

To answer my own questions ! ;)
1. I connected both just in case, supplies power great to CPU, no issues so far.
2. I didn't see any CPU pins, but it works :)
3. Bios flashback only needs power supply and motherboard as far as I can re-call, no cpu, no memory, nice feature ! Ofcourse do make sure not to short circuit the motherboard, install in PC case first for safety reasons ! ;)
