Buying a used computer

Buying a used computer CPU

November 5th, 2011

A CPU is one of the most important parts of your computer system. It’s like the brain of a computer system and is responsible for most of the data processing. As a result it plays a major part in a computer system’s performance.
Buying a used CPU can lead to significant savings at minimal risk. New CPUs are released all the time so older models can be had at a good discount. A second-hand CPU is the most risk free purchase of used computer hardware you can make. This is because a CPU either works perfectly or not at all so it’s easy to tell what condition it is in. If it works at all then it’ll continue to work happily for decades. If it doesn’t work then it’s dead and worthless. There is no room for doubt. However, there are certain steps you can take to ensure that you purchase a fully functioning CPU:

Power supply units and efficiency

May 22nd, 2011

Computer Power Supply Units or PSUs convert mains Alternating Current (AC) to the Direct Current (DC) required by computer parts. Power supplies are typically rated in watts of power they can reliably supply to a computer. But these PSUs aren’t 100% efficient at their job. Some power is lost during the conversion from AC to DC. How efficient they are at their job determines how much electricity your computer uses and that is reflected in your monthly electricity bill.
