What are these?

[Marie Azalea]

What are these on on Asrock A320M-HDV? Is my Psu supposed to power them?

What exactly are you referring to?

You only need 1 post, and could you be more clear? They just look like fan / board headers to me

Those are called headers. Motherboard manuals explain what those are in detail. From left to right they are called HD Audio connector (for front panel audio on your case), clear cmos (incase you do something that causes no post issue in bios), chassis fan header 2, most likely front panel io header, USB2 header.

Best thing to do when you're unsure of what headers do what is to lookup the board on the manufacture's website, get a copy of the manual. The manual generally has very clear indications of what each header does and what its used for. For the headers you showed, Levent is 100% correct. If the front panel io header is not clearly marked on the board, the manual will show you what each individual pin is for. This is where you will connect the power switch, reset switch, power led, and hdd activity led.

Ans to clarify about the psu. No it does not plug in there at all.

 

They also dont all need to be used. Only use the ones you need or want
