Installation  
NOTE: Installation of a power supply requires some mechanical skill and  
requires that you open your computer case to disconnect and reconnect wires.  
If you are unfamiliar with this kind of work, consider bringing your computer and  
new StarTech.com power supply to your local computer store for help.  
CAUTION: Computers contain sensitive electronic components that are easily  
damaged by static electricity and excessive shock. When handling the power  
supply and other components, ensure you are properly grounded using an anti-  
static mat or similar device. If anti-static equipment is not available, ground  
yourself by touching the exterior of the computer case or another large metal  
surface before handling any peripherals.  
1. Check the red switch on the rear of the power supply, next to the power cord plug. Be  
sure it is set to the correct voltage for your country. In North America, it should read  
"115". In Europe and Australia it should read "230". To change the switch, use a  
screwdriver in the notch of the switch and slide it to the opposite side. If you are  
unsure of the voltage used in your country, contact your electricity provider before  
proceeding.  
3. If you are replacing an old power supply in your computer, ensure the computer is  
shut down and disconnect the power cord from the back of the old supply.  
4. Open your computer case. In most designs, the case is opened by removing two or  
three screws at the rear of the case and then sliding the covering panel backward until  
it comes free. If your case is a tower style, ensure that you remove the panel that will  
expose the top of the computer's motherboard. This is generally the left-side panel.  
There are many different case designs, however, so if you are unsure of how to open  
your particular case, consult the user manual for your case or contact your local  
computer store for help.  
5. With the computer case open, review the connectors being used from your old power  
supply. If you are building a new computer, review the connectors that you will need to  
use. Check the type of connector on your motherboard and connect the 20 pin  
ATX power connector provided by the power supply. Should you need the additional 4  
pin connector, please attach the additional 4-pin ATX power connector accordingly.  
6. Disconnect the old power supply connections from inside your computer. Hard disk  
drive, CD drive and floppy disk drive connectors disconnect by pulling on the  
connector. The motherboard connector(s) have a clip that must be pressed while  
pulling on the connector to release them. A rocking motion while pulling will aid in  
getting the connectors loose. Never pull on the wires of a connector to unplug it.  
7. Check that all the wires from your old power supply are free. Remove the four screws  
on the rear of your old power supply to free it from the computer case. Support the  
power supply with one hand if it could fall while removing the last screw. (Such as in a  
tower style case.) Remove the power supply by sliding it back and then out through  
the side of your case.  
8. Install your new power supply by positioning it through the side or top of your case

Instruction Manual  
(depending on your case style) and then back onto the power supply mounts. Check  
that the orientation with the screw holes in your case is correct; all four holes must be  
aligned. Support the power supply with one hand while threading a mounting screw  
through the back of the case and into the power supply. The screw should thread  
smoothly and should not require effort. Do not force it or you could damage the  
mounting holes. If the screw won't thread smoothly, remove it and check to ensure the  
mounting holes are correctly lined up. Repeat for the remaining three screws. Do not  
fully tighten any of the screws until they all have been threaded into their mounting  
holes. (Note: Consider Startech part SCREWTHUMB screws for easier installation.)  
9. Tie unused wires away from fans and other moving parts.  
10. Replace the case cover and secure it. You may wish to not replace the screws until  
after you have checked that all connections are working.  
11. Toggle the rear power switch on power supply to off. (The "0" symbol on the switch.)  
Connect the power cord to the power supply and plug it in to a grounded power  
outlet. (The power supply MUST be connected to a grounded outlet.) Toggle the rear  
power switch to on.  
12. Start your computer. You should hear its fans and devices immediately begin to run.  
If you do not, toggle the rear switch on the power supply to off, disconnect the power  
cord, open the case and check that all connectors are well seated and secure.  
13. When you have confirmed all connections are working, replace the screws in your  
case.  
14. Power supplies contain electrical and electronic components and should be disposed  
of properly. If you replaced an old power supply follow your city's rules for proper  
disposal of electronic equipment.
