I assume you are aware of it but for the sake of completion, battery runtimes are sold in amp hours AT THE RATED VOLTAGE FOR THE BATTERY - so you will need to multiply the AH by the voltage of the battery to get the the watt hours - which is more useful. Most UPS manuals will have runtimes at various loads documented.
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.

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?

When do I need a pure sine wave UPS? - Super User
The UPS you mentioned will have a plus-or-minus 10% variance in output voltage level when compared to mains current and provides a square wave instead of a sine wave. Either can be problematic for some computers.

Background UPS Mail Innovations uses several different types of tracking numbers. The longer number above is indeed a US Postal Service (USPS) "Intelligent Mail® Package Barcode" (IMpb) number. (In this case, it is 26 digits long, but there are other valid lengths.) The prefix 92 identifies it (for most practical purposes) as a postal tracking number. (`92' is the GS1 Application Identifier ...

This CyberPower news article says: higher end workstations and computer systems that incorporate Active Power Factor Correction (PFC) power supplies may unexpectedly shut down or crash entirely when used with a simulated sine wave UPS. CyberPower use the term, PFC Sinewave, and APC (APC 1500VA/900W UPS ) uses the term Sinewave UPS.
Should the UPS output be exactly same in normal and battery backup modes ? Of course the AC line power from the electrical utility is true sinusoidal with an accurate frequency of 50 or 60 Hertz. The typical (standby and line-interactive) UPS will pass through the line power when in normal mode. Typically only a high-quality UPS will output true sinusoidal AC power when in battery mode. A UPS ...
0 I am new to UPS API. I have 4 different applications to handle UPS related tasks 1)UPSRating 2)UPSQuantumView 3)UPSShipping 4) UPSTracking for common methods, I have one application, 'UPSCommon', and I want to use that application as a dll in the other 4 applications. In UPSCommon, I have to write code for OAuth2 authentication.
The VA rating tells you about the maximum load you can put on the UPS, and this can also be a very loose proxy for the quality of the components - because higher rated UPS's will typically have componentry and cooling which can support higher currents and are thus more robust.
The UPS Track by Reference Number API does not properly document the fromPickUpDate and toPickUpDate parameters: fromPickUpDate Default: "currentDate-14" toPickUpDate Default: " currentDate " The actual date format is not specified. In a PHP library implementing the legacy XML version of the API, we can see that the parameters use the Ymd format (source):
