I was wondering if there was an inexpensive brownout and surge protector out there that is not over hyped but will do the job. Probrably 8 out plug inputs would do. Can I get anything locally like office depot?

I was also wondering to if a new
MacBook pro was really close to the render speed of my 2.66 quad first generation mac pro and I'm talking about the 17" inch model.

Something like this should be available at an Office Depot/OfficeMax/Staples.

I've been using APC for years, works great. I get the one priced around $95.
All the outlets are surge protected but only a few are on battery. So make sure you get a model with the right number of battery plugs for your needs. Or maybe buy 2.

After looking around the APC site, the unit Dexter linked to is the exact model I would get :)

They work a treat, ideal for use with workstations, monitors etc...no need for male-female mains cables

I've used APC for the last 5 years with no problems.

These are not inexpensive, but where could I get something like these in Europe?

APC is the only way to go. Not having a good battery backup is like going to Bangkok without a condom.

I have two APC 650 VA, old models, but they were good, & I have recently repacked them. But..... most UPSs are pretty inefficient, a 650va only has an output of about 400 watts, not enough these days.

To run your computer/s you may need something larger, also try to use a more efficient UPS. Look at KVA (input) & Watts (output). Its the watts that you need, not the KVA or VA.

I am currently using an MGE Evolution S 3.0 kva / 2700 watts output (90% efficient (some other UPSs are 95% efficient)), the S model you can plug in extra batteries. I have one EXB module. Extra battery. You will also need a Surge Power Filter.

The 3 internal fans were a little noisy, so I replaced them with Noctua fans which are extremely quiet (if you put new fans in, the wiring is in a different order in this model & from memory one cable needed extending). You could also put the UPS a bit further away.

If a UPS says it can run for say 6 minutes, this is usually down to a flat battery (bad for batteries), 4 minutes will give the battery a longer long term life. My unit with 4 computers running & 2 screens is about 25 minutes (about 1600 watts power consumption), a lighter load across the batteries.

Its worth getting a good UPS, it will be amortised over a lot of computers over a lot of years, & if you need extended run time a model that you can plug extra batteries in is very worthwhile. A good UPS is worth their weight in gold...... & they are heavy...... 34 kg & 42 kg, in my case.

I meant the Zerosurges, or something not based on metal oxide varistors. I don't have grounded sockets at home.

Well show me an APC one that works with ungrounded sockets.

If you want really good protection, “Double Conversion” is the way to go, the UPS output is continually supplied from the batteries while simultaneously being charged. eg MGE Pulsar M, but these are more expensive and I guess the batteries may need replacing every couple of years.


APC & MGE are both part of Schneider Electric, just different marketing arms.

You may not find one without a ground, but the mosfet thing may be used by APC. These are THE guys for this stuff. If it's good, pretty sure they use it.

I'm not really concerned about the battery back up I just want a brown out and surge protector. I'm so obsessed with saving I hit "apple S" constantely. I'm looking for something that is cheap but will protect on those two levels.

Brown outs happen a lot more than Black outs. Depending where you are on the grid & what's in your suburb & within your sub station area will affect your power supply.

My biggest problem is Ring Tail Possums electrocuting themselves. Then trees falling on power lines. Hence the Black outs.

Depending on the level of Brown outs, if the power goes a bit too low for the UPS but its still not a Black out, the UPS will require the battery to bring the voltage within the range selected even though its not a Black out.

The more expensive models will have more adjustments on how to handle power and may also have True Sine Wave power output instead of Simulated Sine Wave power output. You will also want a proper line filter as a most UPS don’t do a lot, even the expensive units.

Here in Australia we have 240 volts, & voltage in the evening is also an issue when everyone is on the grid, it can drop to around 220 volts or even a bit lower occasionally. At other times it gets close to 250 volts.

If you value your computer and want piece of mind, it would be worth saving up a bit and getting at least a half decent UPS & line filter. Allow enough Wattage capacity (“Watts” not KVA or VA) to run a screen as well.

A better quality unit will obviously buy you more piece of mind, even for the Brown outs.

Without a battery, a brownout is going to turn your computer off or force a reboot. A surge suppressor by itself will not help you in a brownout. APC also makes surge suppressors.
