Despite having very reliable power where I live I'm thinking of jumping on the UPS bandwagon now that I've got a DS920+. No real requirement beyond getting the NAS into its sleep mode.
The APC BX750 seems to be Synology compatible based on what I've read online and whilst not its best price I've found it on sale for $132 inc shipping.

Anyone gone with something similar recently ?
Thanks
Sufficient time for the NAS to safe itself is enough. I don't have any real mission critical needs, more an insurance policy against hardware failures or volume corruption.
And yes, I'm using all four bays.
DS920+ with 4 drives running is much less than 200W
more like 40W

Hmm, I looked up this one based on usage for a DS920+ with 4x 4TB Reds. Guess all the more reason to double check yourself.

Very much doubt the DS920+ with 4 drives will push past 200W. I've got a 6850K with 14 drives sucking under 180W at idle and around 200W when writing to the UNRAID array.
Lol 200w !
my qnap with 4 spinies and 3 nvme ssds use 52w when at max load
I have an Eaton 5E 850i connected to my DS918+. I have it set to automatically put the NAS into safe mode 4 minutes after a power outage, although it then keeps other devices (router, switch, wifi access points etc.) running for 30+ minutes before cutting out. Cheap insurance against serious data loss that could occur if your NAS does a dirty shutdown.
DS1621 here running off a cheap-arsed CyberPower ValuePro 700VA. Have the Synology set to go into safe mode after 5 mins I think. Tested a couple of times, and the UPS signals just fine to the NAS. I think I had one issue where I needed to pull the USB cable, but I only hit that once and not in the past 10 months of use (have had it for 11 months). The 700VA will do our NAS (set to not go down), modem, and Asus Router for around half an hour give or take.
The Cyberpower currently tells me it's outputting around 80W to power those. Your 920 is not going to be sucking down 200W I think unless you're really keepings it active.
I picked up a CyberPower Value 600. Picked one up on sale for like $65, but Umart has them for $85. It’s has my DA918+ that’s got 4 spiny disks and a m2 ssd plugged into it and connected via USB. It does its thing, testes itself, tell the NAS (which then emails me).
I get about 30 mins run time before it shuts down the NAS. Like nicktork said, cheap insurance against data corruption. Before I had mine, I had a dirty shutdown that resulted in what looked like all my photos went missing, Synology support were able to rebuild the database that had all the references.
Yeah CyberPower UPS are great, I use a VP1200ELCD https://www.cyberpower.com/global/en/product/sku/vp1200eilcd approx $250 , similar deal connect via USB to the NAS<>UPS so the NAS shuts itself down in the event of a power outage. I've had two instances where I lost disks - One with someone unplugging to use the Iron (!@#!@) and another just a power outage.
Well worth the investment, set and forget.
I have also considered this. However my NAS is mostly shut down, and its main aim is to reconcile backups and mass storage. So on a good week it wakes up once a week to do its thing.
Is a sudden poweroff /that bad/ for a modern system?
UPS are great added protection but you need to calculate size through properly.
DS920+ with 4 mechanical hard drives would push past 200W usage. That gives you ~5 mins tops of battery backup on that unit with nothing else connected. Is this sufficient for you?
