650VA-2000VA Eaton 5E UPS + Bonus Yubikey 5 NFC $119-$369 Delivered + Surcharge @ Computer Alliance

530

Computer Alliance have a deal where you get a bonus Yubikey 5 NFC with their range of Eaton 5E UPS. Considering a Yubikey 5 NFC can be ~$80 by itself, this seems like a pretty good deal. Some of them are "Low Stock" but the 850VA and 650VA just say in stock. I just picked the 850VA one for the title but the link is for all of them.

1% surcharge for Card & PayPal payments.

2000VA Eaton 5E 2000i UPS $369
1500VA Eaton 5E 1500i UPS $239
1100VA Eaton 5E 1100i UPS $195
Sold out 850VA Eaton 5E 850i UPS $129
Sold out 650VA Eaton 5E 650i UPS $119

Edit: 850i OOS. Changed main link to 650i (Seems I broke the thumbnail. Sorry alvian)

*Kirbieb was still able to buy the 850 even though it said OOS. Maybe worth a punt if you really want that particular model.

>i went ahead and purchased anyway. it just says it will take 3-14+ days to be ready.

Edit 2: 850i and 650i are now both OOS. Can't go to those pages at all anymore.

  • Thanks I was after both

    • +1

      I have multiples of both so as much as I would like to partake in this deal, I really can't justify it.

  • +1

    I'm assuming you can connect this to your NAS to auto shutdown since it has USB. Is that right?

    • +2

      I would go to your NAS' website to check for compatibility. Like this for synology.

      • I did just notice that the 5E650iUSB is not on the list. An oversight or is it not something they recommend at all? There seem to be plenty of other 650s on the list.

        • Should be fine, I believe they use a fairly standard protocol so if a similar model is supported already then that one should work too.

          • @Agret: Yeah, I was thinking that but for pedantic people like me it's nice to see your exact model there. : )

  • +1

    This is a Line Interactive UPS.
    Nice.

    • This can make a real difference. I had a cheap Jaycar one that was line interactive and an APC that wasn't. The APC would cut in frequently and the line interactive one would sail through without wearing down the battery.

    • Sorry for dumb question, but I recently got this: https://www.ebay.com.au/itm/324324985130 for $139, I tried to find out if it's Line Interactive but no bueno.

      Should I return the one I bought, and get one of these?

      • +1

        Standby is not line interactive. This is a better deal. I would return it.

        • Thanks, haven;t received it yet, but I'll return and get one of these

  • How many hours would you get for 50w?

    • -4

      Find the wattage for the unit and divide by 50. e.g., 650va = 360w is 7.2h

      • +10

        No, it has a 12v 9A battery = 108Wh. At 50W this would be 2hrs, but thats theoretical max. Actual battery capacity will be lower, and UPS inefficiencies you're more likely to get a bit over an hour.

    • +2

      you can use EATON sizing calculator
      https://upsselector.eaton.com/Load

      • It is good to go over the amount you think you need, especially if you can one for a good price. Don't go overboard though. A UPS is really only to help your equipment shutdown safely. If you need to run your stuff for a long time with no power, you'll need a generator or something like that.

    • These sort of UPS aren't designed to operate regularly on the battery. If the battery is discharged to the cut off point it will shorten the life of the battery. These sort of batteries ideally shouldn't be discharged more than 20% of their rated capacity. (Crazy I know).

    • +1

      Also, over time, the battery in the UPS degrades,
      and it will need to be replaced.

      So, also find out if these batteries can be replaced
      and how much they are.

      • Just as an FYI for real world experience. I have a 5E 1500va that is about 3 years old, I just had to replace both the 9ah batteries as they were cooked. Batteries cost about $50 and that was shopping around, could easily cost double that

        • I have had UPSs for more than 10+ years,
          and even with 2 different brands [CyberPower, Eaton],
          I've have 'expired' batteries.
          And that's with minimal outages, ie. minimal need to rely on UPSs.

          I had to source a replacement after-market battery from eBay.

        • @uncle-shauny the trick is to buy good batteries - it's pretty normal to get 8 years of life before the UPS complains that they need to be replaced.

          12V batteries vary massively in quality, the bargain ones are usually just junk.

  • Didn't know they had surcharges for credit cards and paypal. Is that a recent thing? Haven't bought from CA directly for a long time.

    • +1

      They are allowed to pass on the merchant fee but no more, I think

    • +2

      If they have afterpay, choose that option. Afterpay mandates there be no surcharges.

      • +1

        Afterpay also charges the retailer 6.5% for the privilege, so keep that in mind if you use it at a small store that you want to actually support.

      • (profanity) Afterpay.

  • What is the purpose of these exactly? Why do people buy them?

    • +6

      To keep their desktop/server running long enough during a power outages to be able to perform a safe shutdown.

    • +2

      There are a few uses but most people probably buy these to protect their computers, NAS when the power goes down. You can set up most of the better UPS to tell your equipment to shutdown either when the power goes out or when a certain amount of battery time remains.

    • To protect against power outages for sensitive machines/work loads.

      Once the main power is out it gives you time to gracefully shut down the machine, or even save whatever is being worked on.
      Even a regular PC, forced power outages can cause issues software wise. While they'll survive 99.9% of the time but it can happen.

    • +5

      Generally it is used for when the power goes off intermittently (brownouts) as well as allowing you to shut your computer down and save files during a blackout. The brownout can cause damage to pc parts, something i'd be considering if I had a expensive graphics card. blackouts are just a pain in the arse, especially if you work from home and lose a bunch of work. if you just browse the web and have a cheap pc you probably don't need one.

      just to show off to friends and relatives.

  • 850VA Eaton 5E 850i UPS is now out of stock.

  • Cheers OP, got one

  • So the 850 is out of stock but i went ahead and purchased anyway. it just says it will take 3-14+ days to be ready. hoping that still honor that price.

    • OK. Thanks, I'll add that info to the post.

    • FYI got my cancellation email today for my backorder of the oos 650 va.

    • Just checked the invoice page and seems I've been issued a serial number.
      A good sign, and lucky, considering I didn't checkout the 850 until 90mins after adding it to my cart. It switched to OOS during that time.

  • +1

    Don’t need but bought. It will be good for my unraid server - should be around an extra hour to gracefully shutdown

    • +5

      Same here - "don't need but bought" seems to be rule number 1 on this site.

      • BFTL = Buy First, Think Later

  • Would this be good for a 3d printer? Does it matter if it is a pure sine wave unit?

    • +1

      3d printer won't care, any style will work. The problem is when it's drawing 400w under load you have a very small window before the battery goes flat, and there's not many viable ways to recover a job after a shutdown.

      Still, would work great in a brownout or other very small power interruption, which would otherwise kill a print.

      • Thanks bro

  • Anyone know the idle power draw of these when the battery is fully charged? I'm looking at the 850 model.

  • Is this the same ups I have that doesn’t stop beeping when activated?

    Super annoying.

    • +4

      Just like the stupid carbon monoxide detector I bought. Unrelated question, anyone know how to make a room stop spinning?

      • +1

        Lay down. Hope that helps

    The 1100VA says- "Battery Type (2)12V 7Ah"
    The 1500VA says- "Battery Type (2)12V 9Ah"

    If I don't need the extra VA I should just be able to buy 2 new 9Ah batteries and put them in the 1100VA UPS?

    • A 7Ah battery is physically smaller than a 9Ah battery so unless the 1100VA unit has empty space you won't get a 9Ah battery inside it.

      You could always wire the battery so it sits externally to the UPS. Then you can have any size you want.

      • +1

        Are you sure? I have put 9AH batteries in my other UPS's before that only had 7AH batteries before.

        • +2

          You're right. I've gotten different sizes before as the alternative wasn't available due to covid related shipping delays. Here are a couple of things I found after a quick google.

          What is the difference between the 7Ah battery and the 9Ah battery? Why would I upgrade?

          Simply put both versions will fit in your application and will work fine. As the dimensions of the 12 Volt 7Ah battery and the 12 Volt 9Ah battery are exactly the same, they are interchangeable. Amp-Hours basically show how much energy a battery holds. As long as the battery you want to replace has the same voltage and dimensions it is okay to substitute it with a different Ah replacement. Keep in mind that in most cases as the Ah rating goes up so does the size of the battery!

          The 12V 7Ah Battery Story

          The 7Ah, 8Ah, 9Ah are a sealed valve-regulated lead acid battery (VRLA for short) and one of the most popular sizes used in UPS Backup, Alarm and Electric Scooter applications. Many of these devices came with a Yuasa NP7-12 battery. Depending on the application it will either have F1 (0.187" wide) terminals or F2 (0.250" wide) terminals. Over the years as technology has improved the 12V 7Ah battery has been upgraded to the 12V 7.2Ah battery, 12V 7.5Ah battery, 12V 8Ah battery and now a 12V 9Ah. They are all the same physical size and of the same voltage. The only difference is that the 9Ah will last nearly 30% longer between charges compared to the original 12V 7Ah amp batteries. No harm will come to your system from increasing amperage.

    • 2 new decent 9Ah batteries will cost you way more than the $40 price difference from 1100VA to 1500VA though, so this wouldn't make sense.

      It's cheaper just to buy the 1500VA unit…

      • I wouldn't replace the 7Ah batteries that come with the unit immediately but in my experience the batteries that come with these units usually don't last very long anyway. So when they do fail I will replace them with 9Ah batteries.

  • what size ups would you need for a synology 1520+ (5 bay nas) ?

  • Hmm I had one these several years ago and it was junk. Didn’t work correctly out of the box which after much frustration turned out to be a bad batch that dodgy ebay sellers were still flogging..

    I went with APC as a replacement at a higher cost and never looked back..

    • +1

      Comparing against a faulty product isn't exactly a fair comparison.

      • Well, the pain involved made me switch. Nothing worse than something deceiving you by looking like it works then fails when required..

        YMMV

    • Buy from eBay, expect junk

      • Not the case with anything else i've bought…

  • +1

    Does anyone have a link to the UPS companion software? The Eaton website is horrible and the US version of the software doesn’t seem to work.

  • Weird that the Yubikey has an Eaton logo on it

    • It's a new key though, right?

      • looks it yeah. im not sure i have a use for it or know how it works tbh. im also trying to install the eaton software for the UPS

    • I just got the UPS delivered but it didn't come with the Yubikey. Is it sent separately?

      • Yeah no clue why. Yubikey came separately on a different day in a satchel way too big

  • Looks like my servers actually using atleast 120-170W at low load, so im not going to get as long as expected. Still about 10 minutes to shutdown gracefully, automatically using the NUT service on Unraid that monitors the UPS battery level and consumption.

    Overall happy with the deal.

    • Pro tip - set your shutdown to happen only when the battery gets down to 60% or so, so it doesn't trigger the shutdown when there's just a tiny power interruption 👍
      Don't set it to a low number like 10% because the lead acid batteries get destroyed quickly if you let them discharge by large amounts.

      • Yep sounds good, cheers.

  • Arrived today. Very happy with it so far.

    I am ready to eat on it tonight.
