Everyone has bought a light bulb. Bigger bulbs give more light. Bigger is better. The problem is they are using different time bases for the surge duration. A typical surge duration is 100 microseconds.
Some manufacturers use one millisecond.
Other manufacturers use one microsecond. The answer is obvious. Most computers use transformers and capacitors in their power supplies. These devices, unlike resistors and light bulbs, are very different in their electrical characteristics. Computers do not.
