They break down proteins to generate energy, and do not produce much heat. They also produce some very smelly byproducts that can make a compost pile stink like rotten eggs or sour milk.

The power conditioner provides protection against surges in power just as a surge protector does, but a power conditioner also maintains a continuous voltage fed to the computer during temporary voltage reductions, such as a brownout.
A 'power supply tester' is a tool used to test the functionality of a computer's power supply. Testers can confirm the presence of the correct voltages at each power supply connector. Testing under load is recommended for the most accurate readings.
