which cpu have surge protection?

[Konstantinos Koutse]

hello guys I wanted to ask I'm very concerned about power surges and spikes I bought a psu 2 weeks ago and I heard that modern psu have built in power surge protection is it true? and also how can power surges created? or power spikes created? can just a simple black out cause them?

Black outs can be related to power surged, granted it really depends. For example, a black out caused by a tree falling on power lines probably wouldn't cause a surge, at least until the power comes back online. However, a blackout caused by lightning hitting power lines would likely cause a surge for relatively close homes to the power line, but that's difficult to predict and there isn't much you can do to protect yourself from it other than unplug the computer during bad storms. You can use a cheap surge protector if you want a little more, but they're generally not going to make a big difference.

Most PSUs have limited protection to modest power surges by nature of their design. Any power supply that can handle both European power grids and USA power grids without needing to flip a switch shouldn't be severely damaged by short power surges that aren't very high.

I keep my more expensive desktops on power strips that have built in surge protection because my house wiring is pretty old, but I still unplug them when I think a storm is bad enough to worry about.

If you want to learn more about power surges, I recommend googling them. You'll get far more information that way than most people here can provide.

alright thank you very much but in my country we never have storms or lightnings and my house is fully protected for power surges but I worry about my pc because I spent over 1500$ on it so if there are no lightning-storms in my country and if there are I will unplug it comeptely could there be any other factor which could cause power surge and could it be stopped cause I heard that llightning is the strongest but we never experienced lightnings

Like I said, if you need more information, Google is your friend. Here is one of the first results that will probably give you all of the information you could want, based on what I've read of it.

If your house is fully protected, then all appliances (including the computer) are protected. That protection is also necessary for near zero power strip protectors so often promoted by ignoring the numbers.

Surges come from many sources including linemen errors, stray cars, and rodents. Most surges are made irrelevant by protection inside electronics (that existed even long before PCs existed). This internal protection is often superior to what is found in power strips. Worse, a power strip protector can sometimes compromise protection already inside electronics.

Do you really have protection? For example, the incoming cable TV wire must connect low impedance (ie 'less than 3 meters') to single point earth ground via a hardwire. AC electric and telephone cannot connect directly. So a 'whole house' protector does what a hardwire does better. And must make that low impedance (ie wire has no sharp bends) connection to the same earthing electrode. If you do not have that, then your only protection is what comes inside every appliance (including dish washer, air conditioner, every clock).

Nothing adjacent to an appliance claims to protect from typically destructive surges. Those items (called surge protectors) only claim to protect from a completely different type of surge that is typically not destructive (due to superior protection already inside appliances).
