With CS3 you have no choice as it no longer works with AC and transformers are no option.
Switching-mode power supplies will keep the voltage for some time when the power fails in the wall outlet, while transformers go down to 0 V immediately.
In which way are transformers better?

What helps is an uninterruptable power supply (UPS).

It is a problem I fortunately do not have but if you do not have a reliable and stable power supply a UPS is one solution.

I had problems with the previous generation switch mode power supply. They were complete rubbish, and I I changed to a transformer that never missed a beat.

The latest Switch mode thingy seems more stable with the cs3. But the damage is done, transformers for everything except the cs3.

There are small UPS that are designed for home use, and they are quite attractively priced. Certainly not in the hundreds of Euro category, the one I bought about 20 years ago was around the £100 mark.

So to check on this I had a look at the manufacturers web page, sure enough, they are still around the same price ...

Agree that UPS might be a good option. Personally, I use one on the fibre modem, my router and the alarm central.
a decent priced one from a different maker, that could work nicely on a cs3. the capacity is "low", but should ok for the cs3

I did start a friendly topic about a problem i did got and you fool?

Goofy, that comment is borderline abuse to a fellow forum member, please temper your comments. /BDNZ

Temporary it is. But duration depends on how strong the UPS is (how many batteries in it) and how much current the connected devices draw. For a CS3 only I would imagine a modest UPS will keep it running a good 4-5 hours if not more.

The UPS keeps my internet connection alive and surfing is not a problem. and who said the ups were my only solution . Last autumn we had a 12-hour power take out and I had working internet all the time......

Yes UPS is only a short-time solution, but it will probably solve your problems. And most ups also have built in power surge protection.

A colleague of mine was involved with commissioning a UPS for the Databank computer centre in Wellington, NZ, back when it was all new and bright and shiney, so this would be in the late 1960's (did you know they had the first drive through teller there in the 1960's, banking from your car). The data centre contained one of the biggest IBM systems in the country, and they had another two similar centres, one in Auckland, and one in Christchurch. They handled the transaction of all four trading banks in the country, and NZ was the first country to have a fully computerised banking system.

The UPS was to maintain power to the mainframe when mains failed, so the mainframe could do an orderly shutdown. But they couldn't use the mainframe as the test load, so they set up three 55 gallon drums filled with brine solution as the dummy load out on the pavement (the system needed to supply three phase power). Above this suspended on a pulley arrangement was a wooden frame with three electrodes that could be raised and lowered as needed to adjust the load current as the water solution boiled off - it was the load after all, so was going to get hot.

The test was set for a Sunday morning when there was minimal traffic around. everything was set up and the test started. All was going well, steam billowing forth and filling the street, electrodes being adjusted to suit the lowering water level, when the Salvation Army citadel opened its doors and the congregation streamed out to find what must have seemed like nothing on earth happening. The requirement was to maintain output from the UPS for 10 minutes, and they reached 10 minutes 10 seconds before the UPS output dies, so they considered the test a success.

I've seen those massive mainframe banks and ups back-ups at the ADP hub in Alpharetta , Ga. It's extremely secure as well. No risk can be allowed for their customer payroll, or benefits data.

And you miss forum rules about to discuss main topic.
You fool around without intelligence comments.
If you want to joke you can do that in another forum area.
Hard to believe?


Please refer to my previous comment......

Hard to believe.....??
