I've read good reviews for an APC Back-UPS ES 700VA - which is 700VA, but it's output capacity is only 405 Watts. Does that mean the 700W power supply in my new PC is over-spec'ed? Or have I missed something? I only want the UPS to run for 5 minutes in the event of a power-cut. How do you choose a UPS to cover your power requirements?
If the UPS is used for a single PC with maybe <300W the 3kW UPS would already be overkill. I don’t know about UPSes specifically but usually boost/bucket converters have terrible efficiency below ~10% load. Of course this should only shorten the battery runtime, not normal power consumption and is probably still relatively insignificant.

Why do you think that He doesn't know him from his schooldays means that he does know him? It would only have that sense if you added something like In fact, he first met him at university.
It's not just you that doesn't know. Now, according to owl.purdue.edu, we should use "doesn't" when the subject is singular (except when the subject is "you" or "I"), and "don't" otherwise. But in the example above, I am having a hard time figuring out what exactly the subject is and whether it is singular.

Thus, "As far as I know, Bob is happy" over "Bob is happy, so far as I know". They are equivalent in meaning therefore, but choice of one over another betrays, for me, certain prejudices. I also sense that "so far as" sounds slightly antiquated and is losing ground.
Which is correct: "So far as I know" or "As far as I know"?
