NUC7i5BNH paired with non-pure sine wave UPS?

Jump to solution

Hello,

I'm going to get an UPS (uninterruptible power supply) to protect my NUC7i5BNH from power blackouts.  However I don't know if I have to pay extra for an UPS which produces the so called "pure sine wave" power when running in the battery mode or if i'll be OK with a cheaper UPS producing "simulated sine wave".

It depends on whether the NUC's adapter employs the so called "active PFC (=power factor correction)" in which case it might be incompatible with simulated sine wave UPSes and become unstable when powered from such UPS battery. Non-PFC and passive PFC adapters should be OK with simulated sine wave UPSes.

I checked the NUC's adapter. It's model "FSP065-10AABA" but theres no information about it on the FSP manufacturer websites. I asked the manufacturer about it via their contact form but they haven't responded.

So, do you know whether this particular adapter uses active, passive or no PFC? Or did you try whether this particular NUC runs fine with CyberPower Brics UPS which outputs simulated sine wave power? I don't want to pay more for CyberPower PFC Sinewave if I don't have to.

Thank you.

Well, it is always best to get a UPS with sure sine wave output. That said, is it actually necessary?

Power supplies less than 100W are not required to - and do not - support Power Factor Correction (PFC), so a pure sine wave UPS is not required. Those that are above 100W. however, are required (for certification) to support PFC, however, so a pure sine wave UPS is probably best.

Hope this helps,
