The PC's rising energy demands
BBC’s Click programme has a story highlighting the impact that PCs make on the environment, in terms of their growing energy usage. As computers have gotten faster and have started handling increasingly complex applications, their energy consumption has risen in line with this.
“The processor was probably 15 watts of consumption and the graphics cards was about 10 watts of consumption. Then you had your hard drive and your floppy drive, so even given the 10 or 20 percent headroom you need to operate the computer you could easily do a 130/140 watt power supply.
“Today we are selling power supply units at 1,200 watts.”
