Default UPS Recommendations

Hi, I'm planning to buy a new ups to go with my new Formula 450w psu, my requirements are:

It needs to have a good power surge protector included.

I will not specify my budget, instead I want you to tell me how much will gets me in terms of ups.

I like sine wave UPS units

Funny story; I once lived in a place with a lot of power cuts and the heated blankets would turn off with a non-sine wave UPS, so I moved to sine wave.

An example

but you want 230V units

I would avoid the ferro-resonant units even if they are intrinsically very good surge protectors (they are inefficient)

At one point I got tired of the cost of replacement batteries and converted a UPS to run on super-capacitors

Also tried to figure out how to make the batteries last longer

Now I live in a place with better electricity, and have stopped using UPS units.

Then get a surge protector

https://www.amazon.com/Tripp-Lite-In...ripp+lite+240v
This one is 680J

but some 120V units can handle 3,300J

(I have a house full of them)

Default PSu Surge Protection

Hi, can a quality psu protect against small surges.

For example will a 450w formula protect against small surges? What about a monitor ac transformer?

Computer power supplies have some surge protection built in

The problem is not the small spikes but the rarer large ones.

https://www.amazon.com/Surge-101/b/r...d_i=B00P2GW7MG

claims
"Over 50% of equipment failure can be attributed to power surge/failure"
and also suggests a computer needs 2,000 J or more protection; the Tripp-Lite isobar 8 has 3,840 J ability

If this is the cause of the majority of failures, as claimed, one probably wants to take it very seriously.


I like the Tripp Lite isobar ultra series as they don't use plastic cases (some people have had surge protectors go up in flames) and use much more than just MOVs for protection as well as telling when the protection is lost, one reason I don't feel the need to replace them every 3-4 years as the article suggests. The circuit does not just absorb the spike but reflects some of it back out.

I feel the need to protect more than just my computers, so have quite a few Tripp Lite units I have acquired over the years. Tripp Lite are now on the 3rd generation of the isobar series, but I only have one from this latest generation.
