Eaton 5SC UPS – 1000 VA / 700 W, rackmount 2U, 8× IEC‑C13, LCD display – 5SC1000IRBS – Reliable design, durable shielding, black (B09KNPWP2C)

The UPS can handle LOTS of equipment and has already helped me through a few power outages and kept my systems online. It is very big, about the size of a desktop computer. The only downside is there's a small fan inside that is extremely loud and runs 24/7, which makes it clearly intended for a server room or electrical room, so if the UPS is going to be put in one of those rooms, this is perfect for you otherwise if you want to use it for home use, don't get this one, get a quieter one.

Replaced the noisy fan with a rubber mounted Noctua and whilst this still needs to go in a cupboard (I use the tiny old built-in wardrobe in our bedroom-turned-office) it is now no worse than a Synology server. Trust me that before hand you could hear this thing in the room below. Quite how Eaton thought the original was acceptable (or didn't instigate some form of variable speed) I'll never know. Only giving 3 stars due to the noise, but also (and yes, I KNOW ratings aren't about condition or service, usually) as the one I bought from Amz Warehouse had clearly been returned perhaps twice likely due to the noise and was a flippin' bargain!

The single small fan on this UPS moves a lot of air out to keep itself cool, the problem is it does this 24/7 and is unreasonably loud. I only used it for one night but it sounds like the fan runs at max speed (sounds like a house fan/ table top fan) when charging or using the battery and when it's idling it sounds like a gaming PCs GPU at max fan speed. From what i read this should be a very good UPS but because of the noise it makes i'm assuming it's designed for server rooms and not the home.

Very disappointed. Out of box failure. Turns on, noisey fan, turns off after ~2 seconds. Returned to supplier next day. Perhaps too heavy for packaging? Packaging bit untidy but not damaged. May have been dropped but not obvious. Awaiting refund.
