The Fluffy 2, which is constructed by Emile Nijssen, is called to be the world's most efficient computer. Well, that's what its creator proclaimed it. Anyway, the Fluffy 2 is built on an Intel Core i5-3570K with up to 16GB of RAM, and 64GB of SSD disk space which consumes of not more than 5.9 watts when idle, and 74.5 watts at full usage. Normally, an ideal desktop computer would consume about 30 watts at idle. The Fluffy 2 does really the the difference in numbers between the power usage of an ideal computer, and Fluffy 2 itself.
The question now is how does one create an efficient computer like this? or how did Emille Nijssen created this? Well, according to him, he started his work by simply analyzing the flow of electricity on the motherboard. He considered how much electricity does a component uses as well as the loss on each component. Once he had analyzed it, he then created diagrams based on his findings. And finally, he modded the motherboard to create an efficient computer.
Basically, the Fluffy 2 will be mounted on an IPS LCD Display. Due to the fact that it does not have a graphics card, it won't be capable of high end gaming, but can still run at lower resolutions since its processor has an integrated graphics card. Anyways, it can still run most of the apps at a really low power consumption.
