price looks attractive however wondering if this "Output Voltage Wave Form:  Stepped approximation to a sinewave" is going to create any issue or not. comments?

That waveform describes 98% of the UPS usually sold for home use.  Very very very few have sine-wave output.

 

It is not until you get the the APC SmartUPS series do you get the sine-wave output... but at a much higher cost.

 

All that said, unless you are powering equipment with older analog style power supplies, the sine-wave output does not make a difference.  It makes no difference at all to a switching power-supply in a server.

 

Be aware, the shipping costs on these can be pretty high, as the batteries are heavy.

S/H is $10 looks reasonable. meanwhile i found a review from Amazon in following link about it might not work with PSU with PFC (power factor correction), can you or anyone confirm this is the fact? as far as i know Corsair PSU has this design, like this VX550 that i am using right now.

some other reviews, looks like it should be fine.  Meanwhile to offset S/H cost, using Bing cashback that provide 8.5% cashback

I recently bought one of these "simulated" sine wave UPS's (cyberpower) and was all nervous that it might not work with my active pfc power supply.. As it turns out, it works just fine..
