Many believe (wish) that a protector circuit sits between a surge and the c omputer. Reality. A surge confronts a computer and surge circuits separat ely and simultaneously. Zerosurge pictures show what happens when protect or circuits are removed. Power still flows to the computer. Lights claim disconnected protector circuits somehow work.
Also possible is a computer completely disconnected while power is still connected to surge protector circuits. Again, both computer and surge circ uits connect to AC mains separately - despite myths encouraged by Monster t hat a protector somehow blocks and absorbs a surge.
Most surges are so tiny as to not overwhelm protection already inside appl iances (and Xbox). That same tiny surge may destroy grossly undersized pro tector circuits. Protector failure gets the naive to recommend that unders ized protector.
Monster can sell a three dollar power strip with some ten cent protector parts for $60 or $90. Since it is more expensive, the naive just know it m ust be better. That Monster protector is electrically equivalent to one se lling in Walmart for $10. Read specification numbers.
Be concerned about protectors (ie that Monster) that do not even claim ef fective protection in their specification numbers. Xbox needs a completely different device (also called a protector) that is located elsewhere. But that is a discussion for another topic.
Try resetting Monster's 15 A circuit breaker. That required breaker does nothing for transistor safety. But is essential for human safety.
