Ok now got all your thing to make your power pack
The Pc power can hold a high charge of Electricity Even when been turn off for a long time and sill can shock you so be careful when doing this


Step 1. Ok now got your pc power pack you need know if it works first thing to know when you plug it in it will in be stand by mode and no power be running
now look at the power pack cable and find the one 20 - 28 pin plug look this
 

Step 2. Now you have the plug get a spear wire and bridge the green wire to any black wire
 
now plug in and your should hear the fan spinning now good sin working if you have multi meter you can test the yellow (12v) red (5v) orange (3.3v) cables some power pack have a blue (-5) and white (-12) cables there not really needed for most projects but I kept them as I use them for my arcade board repairs
how to test Power simply set your multi meter to 20v dc (v-) on meter
take black cable that should in com on meter to any black ground cable and touch red cable from meter to the wire yellow (12v) red (5v) orange (3.3v) and blue (-5) and white (-12) if all show right voltage then you have a fully power if don't worry if a little off don't mater to much at all for most thing you be using for
don't have a multi meter don't worry as long can hear fan in side spinning then most likely the power pack working fine any way

Step 3. Now have work Power pack to work with cut all the plug of  the power pack and group up the cables normally have around 16 black ground cables so group them in 5s and put 1 black wire a side as we need that later

Step 4. Ok now time to leave it unplugged for min 3-4 hours for it to discharge
But if in no hurry I be on safe side and leave it for about a week to be sure that most if not all electric has discharged
 even then the capacitors sill may have some charge in them so be careful on next steps

Step 5. unscrew the four screw on top of your power pack and the four on back for the fan and open case
unscrew the four screws holding the pcb board in and take it out of the case
Be very carefully as may sill have some power left in so don't touch any of the parts on the board
(I normally try to take out by picking up by the heart sinks that way if any thin come lose just can resolder them

Step 6. Ok Turn the pcb over and don't touch any parts on the board as may be power left best way with heat skink like before flip it and put back down
now take your screwdriver (Rubber Handed ) and touch the capacitors pins to gaver you may hear a pop or given some sparks or even nothing do a few time for all capacitors
now the board safe to work on

Step 7. follow the green wire down to the pcb now you need to wire it to the black wire you put a side in step 3 you can simply solder them to gaver and put heat sink on it
(heart it to skink it to the wires remember to keep the heart moving up down so don't burn the wires or heart sink)
or
you can desolder the green wire and solder the black wire to where the green wire was you unsoldered before
 

Step 8. ok now time to make your mind up if what to add a Fuse Holder Chassis/Panel Mount it is optional but sooner or later you end blowing it and can be pain to replace as you have take the pcb and solder new pins Fuse and solder back to the pcb
very easy to wire a Fuse Holder Chassis/Panel Mount in now
If you don't what to then skip to step 9
ok find the fuse on the pcb and desolder it and solder two wires to where the fuse pin was
 
then you can just desolder the pin off Fuse and reuse for the chassis panel mount

Step 9. ok now look on the power pack for a label normally on side should show text saying dc out put make a note of this for later mine in table below to give you idea what looking for yours may say some thin different to mine but will be there some where

Dc Out Put

+3.3v

+5v

+12v

-5v

-12v

Amps

28A

30A

15A

0.8A

0.3A

 

Step 10. ok get your case top and your Terminal Post and mark out where they going to go make sure that your Terminal Post you have can take your dc out and the max amps they take bottom row for me in table shows 30a highest one and over are below so the 30 amp Terminal Post just fine to use
now mark out where you putting them leaving enough room between them So you easily use them with your wire to your projects
I find best way to do this was to take the ring from Terminal Post and just use a marker pen to mark the hole in middle of the ring to make a drill stop
where you are going to drill your hole remember to make sure you leave enough room between case and bottom of the case and the Terminal Post not going touch parts on the pcb and you leave enough room between each Terminal Post put your wires to use them easily
 

Step 11. now time to take your Power Drill or Drill press and drill out your holes for the Terminal Post if like me u may what get a ruler and clean up you mark so get all your hole lined up straight
(If you not using a Fuse Holder Chassis/Panel Mount don't do the one in midal hole


step 12. now your have drilled out your holes put the Terminal Post in to the holes some Terminal Post rings got a dint on them and don't fit in hole just take your wire cutters and just a small nip in your holes you have drill best doing this and not cutting the nip off as stop the Terminal Post from moving when in

Step 13. now get your heart shrink tubing and cut some to fit over your wire and the bottom of the Terminal Post and put on your wires

Step 14. now take your wires with the heart skink on and your Soldering iron add some Solder to wires (as so know as tinning your wires) this stop them coming undone in next step

Step 15.  now take Ring Terminal make sure using one with max amps out for me got 5v 30A so using 30 amp one doing make a lot easier to do just put wires in the Ring Terminal and use some pliers or clamping tool press down
If like me added a bit solder to the wire and the heat shrink tubing over the Ring Terminal connection

Step 16. now take your wires with the Ring Terminal put on the Terminal Post (Remember the low to higher for me was -5 -12 3.3 5 12v) then put your nut on top and get a pliers or a Spanner to tighten the nuts up
Then heart up the shrink tubing to make look nice and neat (make sure you go up and down the shrink tubing so you don't damming the wires or bring the tubing)

Step 17. now put the cover back on and screw in down

have fun with your new dc power pack it can used for lot useful things
I use my self for arcade boards power and repair as I had -12 on mine with some boards need to run
I also use for over projects it very useful thing to have around
