Have you ever wondered how much power your PC or laptop consumes? I work on a laptop all day
long... how much juice does it pull?
While studying for the CompTIA Server+ exam, I encountered several statistics for use when
troubleshooting computer problems:
| EQUIPMENT | POWER |
|---|
| MOTHERBOARD | 30 W |
| CPU | 45 W - 150 W |
| RAM 2GB | 30 W |
| OPTICAL DRIVE | 5 W |
Notice the power consumption for RAM is 30 W for every 2GB installed. If you consider a standard
laptop ships with 8GB installed, you're talking about power consumption equivalent to two incandescent
light bulbs.
Assuming a minimal demand on the CPU, a laptop with 8GB RAM is puling about 200 W — with over
half of it being consumed by the RAM.
