Need Help - PSU power connections!

[showhost]

Hi... I posted this earlier and it was confusing apparently, so let's try again...

I am building my first AMD system. As you know, a number of fans and devices require 4-Pin connectors.

The cable" groupings/configurations" from the Antec PSU have me a bit confused...

One grouping leads to a a 4-Pin connector which then branches-off a second 4-Pin connector.

Two others cables are the same except they branch-off a third connector -- some kind of a mini
version 4-Pin connector (anyone know what this is?).

Yet another cable has just a single 4-Pin connector vs. two or three connectors like the ones above.

Question: Any rhyme or reason for the arrangement of these connectors with regard to connecting
up side-by-side fans or adjacent devices?

Does this "branching off in series" diminish or in any way minimize the amount of power each
connector delivers -- in other words should one NOT connect a CD-ROM and a DVD on a split cable and just do one device per cable?

Also, why does the cable from the two Antec case fans branch-off into BOTH male and female 4-Pin
connectors?

And finally, somebody told me that the 12v rail stays at 12.22v -- and I have NO idea what he's
talking about????

Thanks...

These are your normal device cables. you'll be using these for your hard drives/cd-rom drives/fans that use 4 pin connectors.

These are the power connectors for your floppy drive(s).

This is the pentium 4 power connector that was originally called for in intel's specs. they later changed it so this connector is generally just left unused now.

I just go by however works out to be the cleanest; as in the least mess.

As long as you're not splitting out a single connector for all your devices you should be fine.

This allows you to connect it to your power supply, and still have the other end of the connector to plug in another device so that you won't run out of plugs.

Don't worry about this. 🙂

hope this helps!
