The power consumption of a computer system component refers to the amount of electrical power it requires to operate. It is typically measured in watts (W) or kilowatts (kW). The following are some common components in a computer system and their approximate power consumption:
-
Central Processing Unit (CPU): The CPU is the brain of the computer and its power consumption can range from 35W to over 125W, depending on the model and clock speed.
-
Graphics Processing Unit (GPU): GPUs are responsible for rendering graphics and their power consumption can range from 75W to over 300W, depending on the model and performance.
-
Random Access Memory (RAM): RAM is a type of computer memory and its power consumption is usually low, around 2W to 4W per module.
-
Hard Disk Drive (HDD) or Solid-State Drive (SSD): HDDs and SSDs are used for data storage and their power consumption can range from 2W to 15W, depending on the capacity and speed.
These are rough estimates and the actual power consumption of each component may vary depending on several factors such as manufacturer, model, operating temperature, and usage patterns.
