It is more efficient, not in the AC to DC conversion sense that is directly associated with electrical bill savings kW/H (homes), unless charged by VA (as Operandi stated), but in the sense that it can increase runtime of a UPS. Is that not a product of increased efficiency?

2nd DING DONG...UPS is designed to allow the user to safely shut down the PC in the case of a power interruption, not to run the PC when there is NO AC power!
UPSs are designed to
power your PC long enough during short term AC power loss for uninterrupted operation (e.g. 3 second power loss during online gaming session) & long term so as to power a system until a system can safely be shutdown, as you've stated. If UPSs are also intended & can run longer or power more electronics for the given power due to active PFC. I don't see a problem with that
The latter reason being beneficial if I were on a deadline to finish up work for a office presentation the next day. Power loss means the presentation that was intended to be ready the next day is not. All because UPSs aren't designed to power a system for as long as possible? If true please explain why APC's UPS software for example offers the option to "Preserve battery power" (shutdown ASAP after time limit) or "Keep my computer on as long as possible" when both modes can be set to automatically go into hibernation.

3rd DING DONG...most PSU vendors in the US will charge a small price premium for PFC. There ain't no free lunch. The EU mandates PFC, that's why those PSUs come with PFC. Seasonic is more expensive because of the name, just like OCZ.
1. If active PFC increases runtime on my UPS and allows me to connect more equipment to a single electrical outlet. Then I don't see a problem with having to pay a small price premium for it.
2. Europe's power isn't as clean as the US's, hence the need/requirement for active PFC in Europe.
3. A name Seasonic rightfully built upon & deserves. To me, Seasonic means quiet PSUs, quality, and until recently up there with the best in efficiencies - electrical bill savings type. If you think about it another way, Seasonic being the highest in PSU efficiencies per
SPCR rates among the highest of efficient PSUs. Said that, the money saved from electrical costs due to Seasonic's efficiency should make up for the initial cost of the PSU itself.
The OCZ PSU name means Topower for the time being, so take that as it is.

4th DING DONG...most PCs are not connected to a UPS. Surge protector, YES. UPS, NO. If an individual lives in an area that's susceptible to frequent power interruption, then an UPS would be of value. In general, the power grid in the US is quite stable and clean. Do you see big corporations jumping on the UPS bandwagon?
Given the same power output ratings, the Enermax, Fortron, and Seasonic will ALL deliver the appropriate voltage and current to the PC.
1. Most? perhaps or not. Really can't say for sure either way, however
45% isn't exactly a # to be igonored. Granted, it's a poll on ATF members but I don't really see the cost of UPSs as a reason why the average consumer can't get one. Heck, I got my 500VA for $15 AR.
2. IMO the cost I put into the UPS I bought, which also happens to be a surge protector, more than made up in value for the peace of mind security that it provides along with those times my power is cut off for a second or so due to lightning storms.
3. I do see corporations jumping on the UPS bandwagon. If anything their need for UPSs are above that of home users. Especially when they have servers & workstations that run 24/7 & are setup with backup & redundancy. I'd imagine downtime of those systems would cost $, wouldn't you?
Real life example: Some months ago SETI@home's (not a big corp. although funded by) servers were down for a few days because it took them awhile to restore the data that was corrupted. The corruption occured due to power loss which would have been prevented had they connected a UPS at the time.
