Installation
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. 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.
2. 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 dierent 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 use either
the 24 or 20 pin ATX power connector (break away the additional 4 pins on the
connector if your system uses a motherboard with a 20-pin connector).
6. Disconnect the old power supply connections from inside your computer. Hard
disk drive, CD drive and oppy 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
(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 eort. 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 o. (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 o, disconnect the
power cord, open the case and check that all connectors are well seated and secure.
13.When you have conrmed 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.
