I just moved and the power in my new place needs help. I can see wiggles in my monitor. It didn't do this at my old place. It gets worse when there is more current draw in the house, such as when the drier is running. I am using an APC smart-ups 700, and that helps some, but not enough. Anyone have any ideas how I can make it better other than move?

Does the APC smart-ups 700 have AVR?

According to APC's web site, yes. It does help running it through the ups, but it is still there.

Don't know what AVR is because I don't have any much experience with UPSs, but am I right in thinking that it is where you are always running off the batteries? Methinks that would be more than enough filtering, although again i'm rather fuzzy on UPS terminology and anything more than a basic understanding of their workings.

So it gets worse when there is more current draw in the house. Try reducing the current draw. Turn off the lights and the fridge.

And if this is your new house, and you plan on living here for multiple years, talk to an electrician. It would probably be in the best interest of all your electrical appliances that the power gets fixed.

Now that you have just purchased your new computer, how are you going to protect your investment? With the recent power problems experienced in various parts of the country and many power experts saying that soon we will be having these issues in every major metropolitan city in the country, you must have complete protection for your computers. There are two types of UPS for the desktop category a Stand-by and a Line-Interactive UPS. The Stand-by is a simple UPS that will protect your computer against over voltages and surges caused from lightning strikes. During a blackout the UPS will also switch to battery backup and continue to provide power to your computer until it is safely shutdown. A Line-Interactive UPS is a little bit more sophisticated than the stand-by UPS. It has all the features of a stand-by plus it has built in line conditioning known as AVR (Automatic Voltage Regulation) that cleans up dirty power that is flowing through the utility lines. A UPS with AVR is the perfect device to guard against all power disturbances – including blackouts. The slightest drop in power can cause your computer to freeze or shut off, both resulting in lost work, data and time. So be sure to get your computer protected with a UPS that has AVR technology.

You say that the monitor problem is less noticeable when powering it through the APC unit. When my APC intervenes because the AVR has detected a voltage drop, the unit tells me it intervened, and I can hear it even if it didn't tell me. Do you have any knowledge that it is intervening? If not I would doubt that it is a voltage drop. That upc you have is a commercial grade puppy too. It has all sort of nice filtering on it. But it should be telling you that you have a problem. I would suggest instead that it may be a wiring problem best diagnosed by a qualified electrician who could come and look your house over. Maybe something like a grounding issue. Is this an older house?
 
I concur - if there is a problem with the electric wiring, you must get electrician to have a look at your wiring.
 
Thanks for the replies everyone. It is an older house, but has newer wiring. I will check the ground etc and make sure the wiring is good.
