Build a Better PC
The AMD Processor in a Box product, featuring an AMD Athlon processor, comes
assembled with a premium ball-bearing fan and heatsink. The unit is assembled with
a thermal compound that provides the thermal conditions required for your system.
You have it all in one unit. It’s fast and easy. It’s a great way to build a better PC.
The boxed processor is factory-sealed to ensure authenticity of your AMD processor.
The Certificate of Authenticity included in the box validates that you have purchased
an authentic AMD Athlon processor. Plus, we stand behind our product with a three-
year limited warranty, offering peace of mind for you and your customers.
In addition, the AMDAthlon processors undergo extensive testing for compatibility.
Hardware and software tests are performed in AMD’s internal compatibility lab. The
Microsoft WHQL and XXCAL also conduct independent testing to evaluate
compatibility with the installed base of x86 software and operating systems.
Buying quality AMD products from an authorized distributor makes good business
sense. When you buy from an unauthorized distributor, you risk getting chips that
have been re-marked or mishandled somewhere in the pipeline—problems that are
invisible until the part fails to perform in your system.
Why Buy Processor in a Box?
Confidence, Convenience, a Limited Three-Year Warranty, and More
The confidence that your AMD processor is marked accurately and the internal
architecture matches the speed on the package.
The convenience of having a processor module with the appropriate heatsink and fan,
assembled, and ready to install.
A three-year limited warranty on each processor you buy with assembled heatsink and
fan through the Processor in a Box program. Products other than Processor in a Box
products provide only a one-year warranty.

Before You Start Building
Follow these steps before you start building your AMD Athlon processor-based PC.
On page 89 there is a checklist for assembling AMD Athlon processor-based systems.
You can use this checklist to verify the steps of the assembly process as you proceed.
Read the FAQ and Recommendations
The FAQ (frequently asked questions) begins on page 66. The configuration
recommendations begin on page 77. Read the FAQ and system configuration
recommendationsbeforeyoubeginassemblingyoursystem.
Take Notes
Get a small notebook (a three-ring binder with lined paper works great). Keep notes
on what you’re doing, especially when trouble-shooting a problem. This keeps you
from making the same mistake more than once. When dealing with technical support,
always write down the name, telephone number and extension of the technical
support person who helps you.
Write clear and understandable notes on the resolution of the problem or call, and
don’t forget the case number. It can be very useful when having to call back later if the
problem was not resolved in your conversation.
Serial Numbers and Receipts
When you buy a component or peripheral, write down the serial number on the
receipt. Make sure you place all the receipts inside an envelope, and keep it in a safe
place. If you need to send a component back under warranty, you will have the receipt
and serial number required for the return RMA (Return Manufacturer Authorization).
You get a side benefit by having records of your computer and peripherals for
insurance purposes as well.
Make a photocopy of the Microsoft Certificate of Authenticity, which has the CD-Key
code of your operating system, and copy other critical program access codes and keep
them with the receipts.
Basic Tools
Basic installation of computer components requires a minimum set of tools as follows:
1. A #2 Phillips screwdriver
2. A very small, straight blade screwdriver
3. Needlenose pliers and diagonal cutting pliers
4. A nut driver for screws that secure the case cover (The size will vary.)
5. A grounded wriststrap to wear while you are working on the system
6. Tiewraps to secure wires and cables
7. Locktite (optional)

11
22914B/0—September 1999 A Guide to Building a PC with an AMD Athlon™Processor
Surge Protectors and Uninterruptible Power Supplies (UPS)
Probably one of the most overlooked items is a surge protector or UPS unit. The
power that runs in most homes and businesses can have substantial variations (i.e.
drops in power, spikes in power, etc.).
The purpose of a surge protector is to protect your computer (and peripherals) against
an electrical spike. You can guess what channeling a very high voltage through your
computer can do. At a minimum, you should have at least one surge protector. Better
yet, if the budget can afford it, acquire a UPS.
A UPS usually has additional safeguards built in which allows your computer to deal
with drops, brownouts, and even total failures, depending on the unit you purchase.
Many units have voltage regulators to keep the power to the computer absolutely
uniform. This is the optimal performance you want.
A UPS is designed to keep your system running, even with a total power failure, but
only for a short period of time to allow you to properly shut everything down. Only the
more expensive UPSs, with substantial additional battery reserves can keep running
for extended periods of time or support additional devices like printers or scanners.
The manufacturer of the UPS can provide performance rating information.
If you can, get a good UPS with power conditioning for the computer, modem, and
monitor. All other peripherals should be plugged into a quality surge protector.

Building the System
Step 1. Your Computer Case
The recommended computer case that you buy (see Table 5 on page 79) can be a
complicated mechanism. Take some time to learn how to take the side panels off and
put them back on. It is a good idea to ask your salesperson to show you how the case is
disassembled and assembled—especially the installation of the power supply.
Photo 1. Your Computer Case

14
A Guide to Building a PC with an AMD Athlon™Processor 22914B/0—September 1999
Step 2. If Necessary, Install the Power Supply
If necessary, install the power supply in your case as shown in Photo 2. Secure the
power supply with screws and bolts as applicable as shown in Photo 3.
Set the power supply to the correct voltage setting—either 115V or 230V as shown in
Photo 4. In the United States we use 115V.
WARNING
Do not plug the power supply into a wall outlet until you have completed
all the steps of building your PC and you are ready to turn it on for the
first time.
AMD Athlon processor-based computer systems distribute power to the motherboard
whenever the power supply is plugged into the wall. You can damage components by
inserting them or removing them from the system when the power supply is plugged
in—even when the system is turned off.
Always unplug the power supply from the wall outlet when you work inside your
computer system.
