5 LIST OF SAFETY
PRECAUTIONS
05 CLEANING
With the exception of the exterior of
the case, never try to clean any part
of your system with any liquid
detergents or cloths.
If you find a build-up of dust inside
the machine after some time,
disconnect the unit completely,
remove the case sides and use an
Air Duster to blow out the dust from
the case.

CASING
 A Casing or computer chassis is the system cabinet that
helps protect and organize all the components inside of
your computer.
Choosing a case for your PC is usually one of the most enjoyable parts. This will be the looks of
your new machine and will reflect how you want your PC to be seen.
Casing is also known as: computer chassis, system unit, base unit, cabinet box, enclosure, housing, tower or simply case.

PROCESSOR
 A Processor or "Microprocessor," is considered as the
brain of the computer. Central Processing Unit (CPU)
performs all types of data processing operations.
The two main categories of processors are
32-bit and 64-bit.
The type of processor a computer has not only affects
its overall performance, but it can also dictate what
type of software it uses.
32-bit computers support a maximum
of 3-4GB of memory
64-bit computer can support memory
amounts over 4 GB+.
Common number of core:
In market,
Normal computer
1-8 core
Dual core, Quad core,
Octa core.
Casing is also known as: CPU, central processor or microprocessor.

CPU COOLER
 A Heat Sink and Fan (HSF) is a thermal conductive metal
device with cooling fan designed to absorb and disperse heat
away from a high temperature object such as a computer
processor.
CPU Cooler correctly is
important for keeping
your computer cool and
quiet.
The processors generate
a tremendous amount of
heat.
Without a CPU cooler, a
processor would burn
out.

features a port that fits a data cable,
such as an Ethernet cable, which runs
from each NIC to a central hub or switch.
Wireless Networks • A network interface card does
not have to be hard-wired with physical cable.
Wireless cards are installed like their wired
counterparts, but rather than a port for a cable, the
card features a small antenna

computer.
Caution: Do not open the power supply, it contains capacitors that are capable of holding hold
electricity even if the computer is off and unplugged for a week, if not longer.
Troubleshoot:
Connect the
Green Pin and
Black Pin
To check the
Power Supply if
is still Working.
Do I need a 600 watts unit?
The chances are that you probably don’t, because typically, on a basic system, you’re likely
never going to go over 400 watts, even with an Intel Core i7 processor and RTX 2070
graphics. However, a 600 watts power supply will give you a piece of mind and gives you the
option to install a second graphics card.
Casing is also known as: PSU or power supply unit.
