Objectives • After completing this chapter, you will meet these objectives: ▫ Open the case. ▫ Install the power supply. ▫ Attach the components to the motherboard and install the motherboard. ▫ Install internal drives. ▫ Install drives in external bays. ▫ Install adapter cards. ▫ Connect all internal cables. ▫ Re-attach the side panels and connect external cables to the computer. ▫ Boot the computer for the first time.

Open the Case • Size & shape is the ? ▫ Form factor • Prepare ▫ Lighting, antistatic mats, container for screws • Each case opens differently

Install the Power Supply • Fits one way • Screws attach it to mobo • VIRTUAL DESKTOP: POWER SUPPLY • LAB 3. 2 INSTALL POWER SUPPLY

Install CPU & Fan • Put in before mobo goes in case • Put on mat & wear strap • DO NOT touch CPU contacts • Match up Pin 1 • What kind of socket is pictured?

Install CPU & Fan • Apply thermal compound ▫ Helps conduct heat away from CPU • If using an old CPU ▫ Clean off old compound ▫ Isopropyl alcohol ONLY

Heat Sink & Fan • Heat sink draws heat away from CPU • Has a 3 -pin power connector fan • Visit site…

Install RAM • Make sure it’s compatible! • RAM ▫ Temp data storage ▫ Volatile ▫ More= better performance • Align notches • Press until side tabs click

Install Motherboard • Standoffs/spacers prevent mobo from touching case • Align I/O with case • Align screw holes • Tighten screws

Lab • Virtual Desktop: Motherboard • Lab 3. 3. 3: Install Motherboard
