I just built a fancy new computer and currently its hooked up to a low-end surge protector. I was wondering how much surge protection would you consider be adequate to protect my new investment? Would an average lightning strike to your house be enough to fry a computer? Im just a little worried. Thanks for your help.

Don't use a surge protector. Get a good battery backup.

Usually when bad weather approaches ie: thunderstorm i just unplug my pc, and thats that :D

this is quite good

My grandfather has one of these for one the power goes out on his dairy farm. It keeps the coolers and pumps running. Highly recommend!


Srsly tho, the voltage regulation of a good battery backup is far superior to what any surge protector can offer.

Backup power and backup batteries FTW.

for battery backups. I have pretty power hungry computer with a 24" monitor. Wouldn't that suck the battery down in a minute unless you pay over a hundred dollars for a big battery backup?

It's nice to have just so when the power goes out you can safely shut down your computer. I don't have one to use it for work when the power goes out. I just want to get it safely shut down and unplugged.

Expect to pay $150ish for anything decent.
1000va should be the minimum you aim for which should keep you up for 5 minutes or so at idle.
The whole purpose of it is to allow you to shut down properly and also for voltage regulation/buffering.

Any particular surge protector / battery backup that you would recommend? I would like one with a strong surge protection and a decent battery. Thanks again for your help.

I'm currently using a Cyberpower. I had an APC that worked well for years, but it died on me and this one was the only decent size-price at Bestbuy at the time.

how excactly would yu calculate battery requirements, for 800w psu and a monitor, how big battery would you recommend?

Well, it depends. Myself, and other people in this thread, just use there's to shut down properly. If you expect to work on it for the extended time while the power is out then contact NASA. Maybe they can run a direct line to the sun.

..I don't know though. I use mine for the purpose of just shutting down safely.

just to keep it on for at least 5-10 minutes to get everything closed or auto shut down

You don't need anything real expensive then.

This one would do the trick.

This is what my battery is showing me right now on my main PC idling:

It's showing I'm using 232 watts at idle and that I can run for 14 minutes.
CPU at max load with 2 instances of prime95, it shoots up to 272 watts used with 11 minutes of backup.
The 22" monitor is the only one hooked up to it, the 19 is not connected to the battery side.
The system has a 700watt Thermaltake PSU and 3 hard drives.

This is the UPS I'm using:

that's the one i have. i got it from newegg here:

i love it and it gives me a decent amount of time. my 30inch and 24 inch just suck power out of it like no other though

Hmm i guess im going to have to pay a little more than a $100 for a decent UPS. Money is a little tight and I wasn't planning on spending that much. Do you think I can get away with a very strong surge protector or do you think the extra money for a UPS is really worth it?

Well, if the power goes out, so will your computer. The surge protector won't do anything.

http://en.wikipedia.org/wiki/Uninterruptable_power_supply
There are various common power problems that UPS units are used to correct. They are as follows (with a typical example of damage that might be caused):

1. Power failure — Total loss of utility power: Causes electrical equipment to stop working.
2. Voltage sag — Transient (short term) under-voltage: Causes flickering of lights.
3. Voltage spike — Transient (short term) over-voltage i.e. spike or peak: Causes wear or acute damage to electronic equipment.
4. Under-voltage (brownout) — Low line voltage for an extended period of time: Causes overheating in motors.
5. Over-voltage — Increased voltage for an extended period of time: Causes light bulbs to fail.
6. Line noise — Distortions superimposed on the power waveform: Causes electro magnetic interference.
7. Frequency variation — Deviation from the nominal frequency (50 or 60 Hz): Causes motors to increase or decrease speed and line-driven clocks and timing devices to gain or lose time.
8. Switching transient — Instantaneous undervoltage (notch) in the range of nanoseconds: May cause erratic behavior in some equipment, memory loss, data error, data loss and component stress.
9. Harmonic distortion — Multiples of power frequency superimposed on the power waveform: Causes excess heating in wiring and fuses.

UPS units are divided into categories based on which of the above problems they address. Some manufacturers categorize their supplies as a level 3, 5, or 9, if they address the first 3, 5, or 9 power problems respectively.

Most decent UPS will give level 5 protection. Surge protectors only cover #3. IMO it's worth it.

I'd also like to point out that the old house I moved into had bad ground wiring. I didn't know this until I plugged in my UPS and it showed me a ground fault error.
