UPS for time capsule

[MarcoCapa]

Sone news!
I decided to opt for a smart ups 750 or 1000 va for pc and I have searched for the time capsule power supply
iFixit says that the AirPort Extreme and time capsule shares the same one and the model is a Delta Electronics ADP-60DFS, but I wasn't able to find if this is an active PFC one or a normal one... If we could find something about this then we could find if a sinewave ups is necessary or not
Meanwhile I have contacted APC to know their opinion about the question and I will contact iFixit today

A sinewave UPS is hardly necessary. The only time a pure sinewave UPS will make a difference is if the connected equipment doesn't like stepped-approximation power (and those steppings will vary from UPS to UPS). The easiest way to know if it matters is to run the connected equipment on the desired UPS and make sure everything is fine. PFC equipment will most likely have a problem during switchover from line power to battery power. Equipment that relies on timing or other waveform-sensitive reasons, like older laser printers, etc. will have a problem just during regular operation on a non-sinewave UPS.

I've run the current model ATC on APC Back-UPS Pro models (along with iMac5K, Mini 2010/2012/2014). No problems in switchover, no problems in runtime. No problems.

If you have a Smart-UPS with sinewave, why not just run the ATC on that? Distance?

Yes
Unfortunately the time capsule is on another floor! I will look to something like back ups pro since you don't have problems!
Many many thank
P.S. Meanwhile APC doesn't helped with the mail and said only "Mac could only work with sinewave ups" ( not entirely true since you use a riMac with back ups pro Bad APC boys)

Finally I have bought an ups for the time capsule
Tecnoware iUps... Found on eBay for 40€.... It is quietly new ( bought on October ), is a pure sinewave and is quite good looking
I will stick with the smart ups for the pc and with this ups for now
