Hi all,
I am planning on upgrading my PC with two high end volta (as soon as they will be released) and a Threadripper or an i9 (I need to choose as soon as icelake will hit the road).

I would like to stay safe and have an UPS of at least 1200W.
Is there someone who can suggest me a good UPS brand with a good UPS greater or equal than 1200W capacity?

Have you ever heard about PowerWalker?
It seems that they have good products.

EDIT:
At the end I choosed the Cyberpower over the APC, APC has really too much weakness in comparison...

Cyberpower SmartUPS PR1500ELCD 1500VA/1350W arrived,
it is deadly silent even with a load of 800W (if not on battery). Most line interactive UPS are silent but transformers can be loud even on some line interactive units.

When on battery the fan curve raise with the load and the temperature but the quality YS-Tech is not that loud.

Thanks to the pure wave my AX860i stopped making that ugly noise coming from the PFC circuit when on battery.

UPS feels solid and premium, the only parts made in plastic is the front panel.
Very easy to swap the batteries, the powerpanel business edition software is amazing, there are tons of cool features for nerds and it works flawlessly on Linux :D

The unit is really really efficient with a powerfactor of 0.9, it converts pretty all of it's power in usable power. (APC is really behind in this)

Runtime is excellent, with a load of 200W (my PC idling with the monitor) it says 2 hours and 15 minutes. Transfer to battery is faster than average UPS with only 4ms.
Surge suppression is based on a series of MOVs for a total of 400 jouls that is more than enough for pretty every overvoltage you may have, leave alone lightning.

They did not spare with the components

It is a 230V unit but there is an equivalent for 110V, the 110V unit is a bit less powerful.

It isn't cheap, but it offers a lot more than the equivalent APC for the same money.

I assume whereever you live the AC voltage is around 200V or at least in the acceptable range for that unit (162-290 VAC).

Have you ever heard about PowerWalker?

No
 
With that amount of wattage you have to go overkill 2.5KVA - 3KVA to have an acceptable Back-Up Time, and we are talking about just 10 minutes, as brands you can't never go wrong with CyberPower and APC.. I have couple of APC Smart SRT 3000VA for the servers with additional battery pack and at about 2500W Load I get about 20minutes back up time, without the extra battery pack it falls to less than 5minutes.

The UPS you linked have less than 4minute back up time at HALF load, unacceptable, at least to me.
 
I have several similar server grade Cyberpowers at work (not sure of the exact models). They are completely silent unless you are on the battery.

for me 4 minutes is more than enough.
I use it for a PC and when the UPS "has sense" I sit in front on the PC and I have time to close everything in 4 minutes.
 
I have one of these, a similar unit and it is silent unless running on battery.

That is my experience with the 1/2 dozen of the server grade CyberPower UPSs that I have here at work.

A few of the are PR2200LCDSL models. Although I do have an older PR2200 model with no LCD.
 
When I want to get some infos on the products I buy I can be very boring... :D

I wrote to the cyberpower tech support:


their answer:


I know that APC UPSs redirect excessive voltage to the ground, so +1 for APC, -1 for Cyberpower.

405 Joules its A LOT man, A LOT... also it's always better to look for the Total Ampere Resistance instead of Joule (Energy) resistance rating... the real standard for surge protection is generally kA.

Anyway If you are worried about surge suppression then I highly suggest to install a Spike/surge Suppressor on the electric panel on your house it is install, set and forget peace of mind, I post that model as that's the one i'm using, but it work as example.. with one of those you can focus in other areas when looking for an UPS.

your suggestion is really good but I am buying a new home and my electric panel is full, there is no room for a SPD on it and it doesn't worth the investment (time and money, specially time since it's pretty cheap)
in any case SPD protects against external overvoltge but not from overvoltage inside the house.

even a washdisher can cause high spikes.

any household appliance device can cause a short-circuit of any kind of magnitude however that's why even regular breakers are for, they will trigger/damage before any other damage can be caused to the breaker control panel, a typical house (two poles/two phases) breaker panel (doesn't matter if 120Vac or 240Vac) are arranged in order to have, for example, rooms separated from laundry, air conditioners outlet separated from room outlets, kitchen outlet separated from bath outlets and so on, each section of the house it's separated to provide a balance on the load to the main panel and to protect/isolate rooms and house sections as you mention with a dishwasher which may cause a short-circuit but that's nothing close of the load any typical 20A breaker can handle, worse scenario you will have to replace the breaker but the short-circuit wont go to the rest of the house. again if you are also concerned about that kind of damages you may build in your next house a dedicated control panel for your desired needs/protections with thermal-magnetic circuit breakers , what I mean with this, is the fact that with a high quality and good protected control panel on your house you have little to worry about protections on a UPS and you can focus on other areas as Pure Sine-wave, Noise, Battery, monitoring tools, network and coaxial protective input/output, etc etc. with so many concerns I recommend to call a good trusted electrical technician so it can build for you a dedicated electrical panel for security and protections for your new house, so you can have some peace of mind regarding the protection of your devices it will better than spending several thousands of dollars buying high-end server grade UPS.
 
I have had a Cyber Power for 8 to 10 years now, replaced the batteries in it once and it is silent except when on battery as others have said.

How did you choosed to replace the batteries? Is there some alert from UPS that tells that batteries needs to be replaced?
Thanks

For me, I use the Power Panel Personal Edition. It has a self test function that forces it to simulate a power failure and kicks in the batteries. I run that every few months. If the system shuts off when I run the self test... well it's time for new batteries. :D

I tought on a more "scientific method" but hey, the experimental method is even a scientific one :D
 
All of the UPSs that I have use a test function. I replace the batteries when the UPS reports a battery test failure or sometimes when I notice that the UPS is hot. When batteries are going bad they will heat up the UPS when it tries to charge them..

I have an older version of: https://www.newegg.com/Product/Product.aspx?Item=N82E16842102070 purchased in 2010. In 2014 the unit beeped at me and gave a battery fault alert.
I went back on Newegg and their price was comparable to amazon so I threw them the business as they made finding replacements really easy.

https://www.newegg.com/Product/Product.aspx?Item=9SIA1TW0RT2156

There were off brands and stuff for a bit less money but for this device I wanted as close to original as possible to ensure safety and such.

My last power outage 2 years ago this UPS driving my rig lasted longer than my FiOS UPS. I have mine set up so my NAS, modem and main rig minus 2 monitors are all tied to the UPS batteries. I was playing DOTA 2 at the time and kept playing on one screen to finish the round then shut down my system and NAS to conserve power since it was not coming up soon and charging phones and tablets made more sense than my NAS at that point. Right now it reads 20 minutes of battery life with the load I have on it but once I shut down the NAS I think it adds 5 to 10 more minutes so I'm well set up.

For me I have been extremely pleased with this unit that has allowed me to shut down my stuff nicely during multiple outages and ridden through others seamlessly.
Replacing the batteries was a bit of a pain but done in 15 minutes.

I'll hear the little fan on mine kick in every now and then if my PC is off and I'm under the desk, thats my warning that its probably time to add replacements to my shopping cart.
 
very satisfied from my Cyberpower PR1500ELCD.
It handle my 850W without problems and it have a great runtime.
I also like the Powerpanel Business Edition software even if there is some features that can't be managed by the software but must be set from the UPS itself.

All in all, I am very satisfied to have abandoned APC, they have expensive products and they are not even competitive.
 
As I said, I have a PR1500ELCD Smart UPS and there are some features not listed in the user manual that I don't understand.
I have three questions, probably someone can help me.

1) If I long press the logs button, I access a menu that shows me the last logs.
Those logs are grouped into two groups with ten values per group, the first X1,X2,...,X10
and the second F1,F2,...,F10
The first group, shows the latest information on blackouts, selftest, and so on but the second group is alwasys empty.
What is the use of the second group of logs?

2) I have noticed that I can set a delay for UPS boot, reboot, shutdown,
what is the use of this delays?

3) If I long press the status button there is a menu that shows the Load Energy: 11.729KWh
what is the 11.729KWh and how can I clear this counter? if it is a counter.

Thank you for your help

The boot delay can give the battery some time to charge. The shutdown delay is how long you want to run on batteries before shutdown in case of a power outage.

I don't think so because I have all those settings set to 0 seconds.
It boot up in 0 seconds, it shutdown ups in 0 seconds, this is the reason why I asked, it's a strange setting.
 
0 seconds means no delay at boot. 0 seconds for shutdown probably means use the % battery level instead.
 
just added a second PC to the UPS and tried to simulate a blackout with the PCs in full load.
First PC is the one that sucks more than 900W, second one added a 300W more or less.

1.2kW of load test passed without problem with an estimated runtime of more than 7 minutes.
Very satisfied about this UPS.
 
Good choice with the Cyberpower. I've gone through 3 APC 1500 replacements while my one Cyberpower PFC 1500 is still kicking and hasn't been replaced once in the same timeframe.

I always bought APC but once I discovered Cyberpower I really doubt that I will buy another APC.
 
I've never been impressed with Cyberpower engineering, while my APCs just keep going and going and going (oops, battery died - replace) and going and going.....

do you have some Cyberpower's bluprints to say that you are not impressed by their engineering?

as far as I see this photos, I see great built quality with very high level parts.
the transfomer is well known, japanise caps, great assembling.

Are you happy with the UPS, can you tell me if you hear a coil whine or buzzing from the UPS when it's not running on battery or is it quiet?
Thanks
 
I've had a number of CyberPower units over the years and none of them were that bad regarding noise.

My PR1500ELCD is the best UPS I bought in years. It is deadly silent during normal operation. No buzz no noise at all. During outage thenfan is pretty silent too. It has an incredible runtime due to its very high efficiency. (0.9 power factor). I loaded it at 105% and it switched on battery without any problems so the power output is not only on paper.

Software is really advanced. I really recommend it for that price you can hardly buy something better. I prefer it over my old apc in every aspects.
