Simple question:

What size cable is used for:

SATA and Molex power?

PCie power (graphics card)?

Diameter.

I want to replace my existing wiring.

That way I can make the cables a exact length to make everything neat and tidy.

18AWG

24AWG

Some PSUs use 16AWG, but I don't think it's necessary.

16-18 gague wiring is used.The thin wiring on a fan is 22 gague(but it to changes to 16 at the molex connector). I bought some custom cables from Performance PC's and I checked what size they used and it looks like right in the middle between 16-18.I would not like 18gague for the 24pin and the 8 pin or the gpu's (too thin) but full on 16 would seem to be hard to work with.I was thinking they used a metric size.16 would be fine if it is not too hard to work with. Making custom cables is nice but you can get a good bit of money in the project.I priced the job using cannon style connectors and pins where possible (cannon is typicaly used for aircraft) and it was way expensive.You have to get the lower computer grade hardware to drop the cost to a reasonable level.

EDIT: I see we have a difference of opinion (small but significant).Like I said,no 18 on the 24,8 or gpu cables for me.

So my cards have two power sockets each.

If I run 16AWG to the first socket and loop of that using 18AWG to all the others, would that be OK you think?

No,you would want to run the same gague wire to each socket.What are you thinking here (asking the reason why you would change gague).

I think it's worth mentioning that the standard Mini-Fit Jr. terminals (ATX pins) are designed for 18-24AWG, and the standard KK terminals (fan pins) are designed for 22-30AWG.

 

My previous post saying to use 18 and 24AWG was based on what is typically used. 16 and 22AWG would be better but it costs more and may require different Mini-Fit Jr. crimp terminals.
