UPS choice help??

I have a rack unit and am needing a UPS. I have seen many studies that show, with today's PSU's in computers, switches etc. pure sine wave is really recommended. There are those that argue that, but it is what it is.

Well, with that in mind, I'm trying to find a rackmount UPS with at least 700 Watts and Pure Sine Wave. This is not easy, unless I want to pay almost a grand. Most are on backorder or special order.

I could get a standard tower, but then it will take up about 5 or 6u in my rack. I guess I could put it on the bottom shelf and put my NAS on the shelf with the UPS. I really want a rackmount though.
Anyone have any words of advice?

I've never heard of such a thing. Granted, all I have is a gaming system and nothing else, but my PSU is plugged into a high-end surge suppressor and I'm having no problems. My PSU was made in 2018 I think. It's the original Corsair RM550x. So, I question this "recommendation" that a pure sine wave is recommended. Maybe it's recommended for things like data centers? I can't imagine a simple home setup would need or benefit from a pure sine wave.

Do a search and find out. I did.

I'd rather not. I recommend you review what you found to see if they are talking about types of systems that are for critical tasks like giant servers or networks for larger businesses. If the kind of equipment you're talking about is at least $1,000, then that is enough proof to me that it's not intended or even needed for common home setups. My system is on almost 24/7 and I do lots of gaming yet again, I have no problems even though I don't have something giving it a pure sine wave, whatever that even means.

Search local warehouses for used APC products.
Add the cost of fresh batteries in the bill, and you will be good to go.
Rack-mount UPS they are made at 1500 to 3000 Watt.
If you find a solution at less than 2000$ it would be a miracle.

But it is probably better to get a standard tower if you want to monitor it. Because ups's with ethernet are expensive. And most rack mount units don't come with usb monitoring.

I'm sorry, I never said it's for just a computer. It is for an expensive switch, a business router, a controller, a server PC, a NAS, and a couple of other things. That's why I have the rack.
The switch itself takes 400 + watts.

Yes, not everyone here is running only a low-end gaming PC with a 550 watt power supply. Most modern PC power supplies are recommended to use a UPS with pure sine wave output instead of ones that only provide a stepped sine wave. This is due to the active power factor correction (PFC) in the PC power supply which is for energy efficiency. A pure sine wave UPS does cost more, but sometimes is just a necessary step for providing clean power to your equipment during power outages.

Personally, I run my home network equipment on a standard UPS and have never had any problems; the power draw for each device is low though, probably less than 100W each. I have had frequent brown outs and interruptions to power and no problems with equipment turning off when being transferred to and from the UPS power. On the other hand, my more expensive gaming PC, server, and other valuable PCs do all use UPS with pure sine wave output. I have a 1500VA UPS in the bottom of my rack as well as some 1500A freestanding UPS. I am using APC and Cyberpower, no complaints with either. Having all rack mounted UPS would look cleaner, but sometimes you work with what is available. In my line of work, I have seen plenty of small and medium businesses that have free-standing UPS in the bottom of their rack.

Also depends on your type of rack. Some network racks won't fit a standard rack mount ups. And you might need a short depth rack mount ups. Which normally costs more. That is why i ended up going with a tower ups for my network rack. And a rack mount ups for my gaming pc. :)

I use a 1500va. And my network uses about 200w. The batteries last about 3 hours.

I ended up with a 1000W CyberPower Pure Sine Wave for $519.00. No problem TwoCables. I understand where you are coming from.

Pure Sine Wave for $519.00
Yes this is the price point of such solutions, I paid 750 (Euro dollars) :)
But I got with it, also the APC software for five nobs control over LAN.
The software pack this is also an important part of a good deal.
