dont worry ive posted 2 pictures to help explain what i mean, so one grouping of wires that comes out from my psu has the three connectors as well as a small on at the end (see picture). and in the second picture is the wires that runs from my case fans. from what i understand i can just connect the male part on the fan wire to the female part on the psu cable??? but what about all the other ones like the small connector?? do i have to connect it to my mobo to?? or is it a personal choice thing? thanks!!

The large plugs seen in both pictures go to your EIDE hard drive(s) and EIDE optical drive(s) like cd or dvd drives. The small black plug(P7) seen in the first photo and small white plug seen in the second are the power plugs for the old 3 1/2" floppy drives. Most systems now no longer see floppy drives included on prebuilt systems while custom builders may have one especially for working with rawrite for the Linux OS.
 
my hard drive doesnt have any of those tho or my optical drives,,, the only thing they match with is my case fans
 
You plug the male end of the molex (4-pin) connector from the fan into the female connector from your power supply. The female connector from your fan is used if you want to connect another fan but don't want/can't use another molex connector from your PSU. The 3-pin connector is used to connect the fan into either the motherboard or a fan controller, you use EITHER the male molex or 3-pin connector to power your fan, you don't use both.

As for the cables from your PSU, the one that's labeled "P7" is for a floppy drive, and the two black molex connectors are used to connect to fans, IDE hard drives, IDE optical drives, and other misc. accessories.
 
Then you are running Sata or Serial ATA rather then seeing PATA or EIDE being Parallel ATA drives there. Sata drives use the wider but thinner 15pin type power connector and a 7pin often red colored data cable.

The two photos here should look very familiar then with the first being the 7pin data cable's plug that goes in just to the right of the 15pin power connector when looking at the rear of any sata II type hard drive or sata optical drive.



The second photo shows what the 15pin connector looks like.
