Power Supply Specs / Capabilities

[ChGr]

I've reviewed the threads regarding power conditioners / surge protectors / power supplies, etc. - this is not a question regarding their value and/or claims regarding noise filtering, etc.

How though, do I figure out what a given device (surge protector, etc.) can handle? I'm sure that there's some formula regarding watts/volts/amps, etc.

For example (and I've arbitrarily chosen a few pieces of equipment below), the Marantz amp linked below has specs that say 800W power consumption, the Oppo says 40W, the JL sub says 1200VA on its plate and of course, other components add more.

The APC reviewed here (and seems to be favorably regarded) says it has 1,440 voltage-amps available:

Does that mean that I couldn't plug in two of the JL subs at 1,200 VA each? What does it mean in the way of the 800W or 40W? Could I plug three of the Marantz amps into it?

I'm not sure I see a 'capability' figure on this Furman:

How much stuff could I plug into it before it quits?

These ATI amps say 2,400 watts on their rear panel. What does that mean regarding the type of power strip/power supply necessary?:

Thanks much.

Meh, measurements is the only sure-fire answer here.

Furthermore, we really need to be looking at and measuring APPARENT POWER, not the REAL Power!

Apparent Power is the vector-sum of Real Power and Reactive Power.

Power transformers and UPS like units are typically rated for resistive loads. For audio amps add a very large safety margin.

So I can run to KMart and grab a power strip for $7.95 and plug in all my stuff?

I personally use 1 of these in each of my systems and never had any problems. The main reasons that I like this one:
1) Those pivoting outlets are really convenient.
2) It has a power switch (with a light)

Now, I don't "really" trust any of these low end "surge protectors", if that is what you are trying to achieve. I only use these for basically getting more power outlets (and the switch).

If you really want/need a surge protector, the only approach really worth pursuing is the whole-house surge protection systems ($$$). If you don't go that route and buy a surge protector, it's really more of a feel-good thing vs truly protecting your gear.

On a side note, if you have a projector, then you also really want it connected to a UPS system.
