1. INTRODUCTION
The power supply of a computer is an important unit as far as functionality of a computer is concerned. It is made of up several electronic components that convert and transform the electrical power from the national grid to suitable power with parameter specifications required for the computer. Temperature is an important factor to electronic components, it affects their performance. This is the reason why some electronic components and devices are made together with heat sinks to help dissipate heat hence avoiding temperature rise. Fans are also installed for cooling the electronic components to avoid temperature rise (Park, Shur and Tang, 2002). The electronic components usually have the temperature range at which the device functions as per the design and if the temperature increases above the design rating the electronic components fails to operate. Voltage changes the temperature of the electronic components. It is noted that change in voltage results to change in temperature of the electronic components. Components usually have a voltage rating with a margin. Voltage above and below the specified margin affects the temperature of the components (Pressman, Billings and Morey, 2009). The data…
