Surge Protector

I used to switch off my PC when I go out. But now, I want to leave it on. Do I need a surge protector ?

If you value your PC, use a surge protector.

Try belkin. They come with insurance for your appliances, and protect against the highest surge spike among those i have seen.

A good UPS can also double as a surge protector. A low capacity one is enough for this purpose

Think about it.

How come your circuitbreaker and fusebox is not good enough to prevent power surge? The most important thing is to have a new modern design fusebox and circuitbreaker at the mainboard that meets or exceeds current safety standards.


Having said that, Belkin strips are not much more expensive than other strips, so no harm getting them, but for real protection, better get good circuitbreaker.

The reason is simple, Belkin strip doesn't protect your internal house wiring from power surge. If the power surge melts your internal house wiring, the cost of hacking the walls and replacing the wiring is going to be scary.

Do I need a surge protector ?
You can immediately identify those who only repeat what they are told to believe. Who never ask questions. Who do not even know what the product does.

How does a 2 cm part inside that Belkin or APC stop what three miles of sky could not? It does not. How do its hundreds of joules absorb destructive surges that are hundreds of thousands of joules? It does not. Why do its numeric specs not even list protection from each type of surge? It is sold to people who automatically believe what they are told. Never ask why. Never demand numbers. Only believe the first thing they are told. Can also be sold the Brooklyn Bridge.

Surge protection has worked and been well proven even 100 years ago. Would earth direct lightning strikes so that operators never remove headsets and leave the room. And then is a scam that does not even claim surge protection in its numeric specs. Take a $3 power strip. Add some ten cent protector parts. Sell it for $25 or $150. Many will recommend the same protector selling for $150 only because it costs more money.

Your telco's switching computer in every CO is connected to overhead wires all over town. Suffers about 100 surges with each thunderstorm. Money is never wasted on scam protectors such as the Belkin or APC. Instead telcos use vastly cheaper protectors that earth even direct lightning strikes ... and remain functional.

Remember, if Belkin, et al grossly undersizes a protector. then the protector will completely fail - provide zero protection. That failure gets the most naive to recommend it. Effective protectors for every home earth direct lightning strikes and remain functional.

Serious protection already exists inside every appliance. A surge too small to harm any appliances can destroy a scam protector. That failure promotes sales especially among consumers who are not thinking. Effective protectors for much less money remain functional.

Your concern is a rare surge that typically occurs once every seven years. That surge can overwhelm protection inside appliances. That surge cannot be stopped, blocked, or absorbed by an adjacent protector. The effective solution was even patented over 100 years ago. Used in every telco CO, munitions dumps, and commercial broadcasting station so that numerous direct lightning strikes cause no damage. That same protector is installed in every house for about $1 per protected appliance. And is sold by far more responsible companies such as General Electric, Siemens, Square D, Polyphaser, ABB, Intermatic, and Leviton - to name but a few responsible companies. An effective Cutler-Hammer solution sells in Lowes and Home Depot for less than $50.

No, you still do not have surge protection. Those are only protectors. What Belkin and APC hope you never learn: a protector and protection are two completely different items. 'Whole house' protectors from responsible companies have the always required and dedicated wire to earth. A wire that must be short (ie 'less than 10 meters). Not just to any ground; single point earth ground. The protector connect destructive surges harmlessly to the only thing that does protection single point eareth ground.

Belkin, APC, and the master of all scams (Monster) will not discuss earth ground. If they did, you would never buy their products. And you would spend less money. Effective protectors earth direct lightning strikes without damage. Even the protector remains functional. But again, technology well proven and repeatedly demonstrated for over 100 years. Not a plug-in scam sold on retail myths.

You should have numerous questions. Especially if you were taken by Belkin, et al retail myths. This old and well proven technology is virtually unknown to an overwhelming majority educated only by retail advertising. Effective protection even from direct lightning strikes uses a protector that costs about $1 per protected appliance.

I hope we are not going into too much electronic in this forum, somehow i can't really relate a surger protector and leaving home pc on.
Some people use for the sake of using for a peace of mind, it is ok but it help to know a little also.

1)you connect all surge protector for all electrical applicances/electrical points?
2)Rarely we have lighting issue cause big issue here, in fact, protector can't really protect it lighting splike through your mains. http://www.webopedia.com/TERM/S/surge_protector.html

To relate to pc what it mean, http://www.ez-max.net/en/view_new.asp?id=209&cid=16

2)How surge normal happen, when an components share on the same line. http://www.techterms.com/definition/surgeprotector
This is common for those multi sockets ,a sudden on one components or sudden on of all if no individual on/off switch.

But it don't relate to leaving home with pc on, to me. For me, i use a good psu cause it equip with necessary protection to shut down the pc to prevent it in case burnt.http://en.wikipedia.org/wiki/Power_supply
Spend money go get a good psu, i leave my pc on ever up to 28days without off, no crash no reboot and i normally leave it on for a least 10days before shutting down for 1/2 days for its break. Now my pc is running to 3 weeks till this monday and will then shut down cause i be on business oversea trip then.

Fierce, but a good post, it said what people don't know or are too lazy to say or to find out.

Sometimes I wonder if the transient filter in computer PSUs are already enough to make buying surge protectors such as the Belkin one moot.
Financial advice from selfish-gen is like Trump's opinion on climate change

Ha ha, that why i feel no necessary to talk into deep electronics details in this forum.
Surge normally happen when you turn on an equipment not when we are leaving home with pc on.

I am no electrician but I think the article over emphasize on lightning strikes. I don't think that covers all surges scenarios that can include blackouts and its restoration.

in fact, protector can't really protect it lighting splike through your mains. [url] Quote]It is a common misunderstanding that surge protectors will protect systems from lightning, the most familiar source of power surges.
Since it is in a web site, then it must be right? According to that citation, every town is without phone service for four days while they replace a lightning damaged CO computer? That is your logic. Or we deal with reality as well undestood even 100 years ago.

Effective proectors are installed so that lightning causes no damage. That screwy citation says lightning is millions of volts? Yes, if one foolishly stops a surge using plug-in protectors. Meanwhile millions of volts are not inside munitions dumps where this well proven solution always exists.

Reality: all surges including lightning are harmlessly dissipated in earth IF a proetctor is distant from electornics and within feet of single point earth ground. How it was done even when operators had headsets attached to their ears during every thunderstorm.

Then include numbers. A typical lightning strike is 20,000 amps. Since effective protectors must make lightning strikes irrelevant, an effective 'whole house' protector is 50,000 amps or higher. And cost less money than plug-in protectors.

Why do telephone COs, connected to overhead wires all over town, suffer at leats 100 surges with each storm? And no damage? Because surge protection routinely dissipates direct lightning strikes harmlessly in earth - without damage. So which is reality? That citation? Or what telcos have been doing for over 100 years?

Many surges exist. When a car fells high voltage wires on local distribution. When the utility has a major switching generated transient. Or lightning. In every case, either a protector is installed to earth direct lightning strikes, et al so that nobody knows a surge existed. Protectors that do not protect from lightning also do not protect from those other destructive transients. A popular urban myth is, "Woe is me. Nothing can protect from destructive surgss."

Electricians are a poor knowledge source. Electricians are taught how to wire for human safety. That training takes years. Electricians have little understanding of why they do what they do. Only know what must be done as defined by code.

For example, proper earthing means no sharp wire bends. Ask an electrician why. If he is not discussing impedance (which is not resistance), then he has no idea what effective protectors do; why it must connect within feet to earth ground.

Surges are not blackouts or when equipment is turned on. Obvious when one learns a difference between high voltage and low voltage. And a difference between current and voltage. And yet so many believe this only because hearsay says so.

One of the most erroneous citations ever posted; that HowStuffWorks citation. So full of myths and outright lies that a previous post in 2003 will only disuss lies on its first pages:

Computer should be powered off at the end of the day using Shutdown or Hibernate. Sleep is for low power pausing.

Blackouts and power on do not create surges. Protection is always about where energy dissiaptes Either a surge harmlessly dissipates in earth - before entering a building. Or that energy will hunt for earth destructively via appliances. Damage sometimes made easier when a protector is adjacent to that appliance.

Computer protection for a computer and everything else is only as effective as earth ground connected to that protector. Protection must be where wires enter the building, Not adjacent to a computer.
