4. Install the Power Supply Fits one way Screws attach it to mobo VIRTUAL DESKTOP: POWER SUPPLY LAB 3.2 INSTALL POWER SUPPLY

5. 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?

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

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

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

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