UPS for 2 Disk NAS and Modem - Anything under a CyberPower PFC Sinewave Series 1600VA/1000W UPS?

  Personally, I run 3 x Cyberpower VP1600ELCD split across my networking equipment including NVR. My Dad also runs something similar for his NAS and networking with 0 issues. I recommend this models as well for any Starlink installations I do and have had 0 issues.

  My view of it is that they have surge protector and avoid sudden power outages which is probably the main two things to avoid failure of a NAS or anything with a Hard Drive. Plus it stops parts heating up during operation and then cooling down due to a power outage before heating back up again.

  I know there has been chatter about the non pure sine wave units and killing equipment, but I have not experience it at all. I've seen UPS units die, but not the hardware running off the unit.

  Decide which UPS you need:

  • Online UPS - always converting ac > dc and dc > ac to keep battery at 100% and power loads in parallel at all times for true uninterrupted power, this is good for sensitive equipment but will likely use a more power due to this dual conversion process.

  • Interactive UPS - ensures battery is 100% and switches to battery within 10-20ms only when there is an outage).

  Note - If you concerned about power consumption, UPS are more efficient when powering >50% loads so it would be really inefficient running a 100w load on a 1000w UPS as you would be likely using 1.25 x the power.

    thanks, it looks an interactive UPS will be sufficient as from reading, the synology power supply should be able to handle the drop before the UPS kicks in.

    interesting about power consumption, the DS224+ with 2 HDDS apparently only consumes 20-30w! and the Archer VR1600v max is 20w! That's a whole 30-70w and with 30% headroom!

    sounds like what I was going for was total overkill, and I need to meet the minimum wattage of the unit.

    sales chat from APC is recommending the BR650MI due to the minimum wattage of 39w, alot of other units have a min of 50w which I may not even meet!

      Most devices do. Even if my house power drops for a moment, my TV will stay on but the printer will reboot. It all depends on the consumption of the devices and whether it truely requires the 240V. A NAS doesn't because it is converting down.

      The more headroom, the better and the longer it will run for if the power goes out. I have a 960W for my just for my Security NVR and it will last 250 mins. But another 960W unit for some other networking equipment is like 140 mins.

      Go bigger than what you think as it allows for expansion and other equipment. My personal favourite for the some of the Cyberpower units is that they have a little screen on them to see all the stats without having to plug in a computer to the USB connection.

  Being using a CyberPower Value Pro 1000VA 550W Backup UPS (VP1000ELCD) for a 4 disks Synology NAS + networking devices since 2021 without any issues.

  However, if you want hours of power during an outage you need a model with a bigger battery. I think mine last for about 30 minutes or so

  i've been using UPSs from the 90s without any problems. i think most SMPSs will handle less than ideal input wave forms
