Question 1

does this support i3 9100f?

Accepted Answer

Yes.  In fact that was similar to what I just built for someone.  That board, an i5-9400f.  The Board's website lists the CPUs supported and any BIOS update required for it to recognize the CPU.

Question 2

Does it come with the cables?

Accepted Answer

Yes, as do all new motherboards.
2 x SATA cables
IO shield
Quick Installation Guide
Support CD

(Check "package Contents" at bottom of "specifications" column on the Newegg page)

Question 3

This product is called Micro-ATX. However, this site and ASRock site specifically state dimensions as 7.5-in x 7.4-in. Is that correct?

Accepted Answer

I wasn't able to get extremely accurate measurements because of the case I installed it into but 7.5in × 7.4in appears to be correct

Question 4

Does this support an i5 2400? And is the ram registered or unregistered?

Question 5

What is the spec on power supplies for this mother board?

Accepted Answer

There is no stated spec for the power supply.   I use 220 watt power supplies with core i5-9400 or core i3-9100 cpu's, 8gb memory, 500 Gb SSD and Intel internal graphics with no problems.  If you need a high end graphics card then pay attention to the manufacturers PSU specs.
