In need of a UPS

[galtbit]

Hello:  I have had a few power outages in the last few days and would like to buy a UPS.

I have a 1300Waat psu
I spend 900 watts on mining rig.

Do I buy a UPS that handles up to 1300watts or around 900 watts?  Any suggestion out there?  Thank you for any answers.

What is the point of having a UPS, if your power is down, so is your internet access. Just get a surge protector if you are worry about your equipment. UPS can only last maximum 2 hours, if you get an expensive one.

The power has only gone out for a few minutes, and not hours.

It may depend among other things, on the specs of your power supply. Is it Power Factor Corrected Power supply?

As an example:
From: http://www.pcguide.com/ref/power/ext/ups/funcSizing-c.html

“ Let's say we have a 650 VA UPS. The wattage limit is not specified, so to be safe, we use 60%, which yields a limit of 390W. This means any load we run cannot exceed either 650 VA or 390 W. Some sample power supply loads:
•   Regular Power Supply, 500 VA Rating: A regular power supply with a rating of 500 VA will run fine on this UPS, because its power factor is probably about 60%, much as the UPS manufacturer assumed (but you should check its specifications, if you can.). Even if the power factor is 70%, that's still 350 W, under the UPS's limit.
•   Power-Factor-Corrected Power Supply, 500 VA Rating: Some power supplies have circuitry added to them that corrects the power factor to approximately 100% (sometimes called power factor 1). In this case the power supply will have a 500 VA rating and also a 500 W rating. This power supply will overload the UPS we are discussing here because its W rating is too high.”

Wrong.....my power goes out quite often & randomly for 5 seconds - 5 minutes,my UPS keeps my miners running & internet up 

It also "smoothes" the power,keeps spikes from damaging my equipment.

If the power is down for longer,well I'm SOL 

I'd go with a 1500 watt,ALWAYS add 20% to your total.You don't want to stress your PSU or your UPS 

Something like this would do just fine:

Maybe some more info would help:

I have a Rosewill LIGHTNING-1300 1300W PSU
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182063

I know the PSU isnt using all 1300 watts but the mining rig uses around 900 watts.






Thank you Anon and Unacceptable for your answers.

not true.

people with DSL/EVDO (plus maybe satellite?) still have internet when the power goes out.

my mining hardware itself is just on surge protectors, but the controlling computer has a UPS. I just prefer clean shutdowns for my rigs rather than just yanking the power out from under them.

I use APC and cyberpower to keep my various boxes up.

Will frequent blackout damage hardware?

I'll install my miner in a place when i expect at least 1 short blackout/day, but as far as i understand i need only a good surge protection to be pretty sure to not damage my hardware...

From your link, and going to the more expanded specs from the Rosewill page:
http://www.rosewill.com/products/1799/ProductDetail_Overview.htm
“Active-PFC with auto AC-input voltage adjustment(100-240V)”

It appears that your PSU is equipped with Active PFC (Power Factor Correction), so it falls under the second example I’ve posted above.

To be safe, you’d require a higher VA rating UPS to handle the power. A 1.6 to 2KVA as Unaccptable noted should be sufficient, for the load. That would cover your capacity (load) needs, and run time would ofc depend on battery(s) Ah size.

In addition, due to the PFC, the UPS would need to be “highend/smart” or closer to true sine wave output.


This maybe of help: https://www.dougv.com/2010/03/01/active-pfc-enabled-psus-are-not-compatable-with-most-low-end-ups/
“In short, if you send a high-end PSU the current created by a lower-end UPS, the PSU’s built-in power factor correction hates it, and cuts power to the PC immediately. As in, the exact thing you bought the UPS to prevent in the first place is exactly what happens.

While I understand the value in having a high-performing PSU — less heat, more power, protection for internal components — a straight-up power off of the PC is never a good thing. So your choices are either to forgo a UPS, purchase a really expensive UPS, or purchase a low-cost PSU”

Hello Anon:  Thank you for the info you supplied.  I was able to plug my rig directly into my Kill A Watt and see that the total amount of Watts is only 720 the most.  Thats  without the monitor, fan an other things not connected to it.  Thats what I really want.  Just to cover the rig.  In that case, what do you think of this UPS?  It can 850VA and t says it has a pure sine wave.  New Egg says it handles 1350 VA 810 w  which may cover it.  Am I on the right track?

you need better then that .  there is a great ebay/refurbished seller  I will find the link.

[galtbit]

Newegg has one that goes up to 900watts.  That would be great Phillip.

yeah the newegg one is a better choice and I did find 1050 watt one above.  I have 5 ups units from the ebay seller.  he is good.  the 900 or the 1050 .  can run the router and your lcd screen .


My best unit  is this one:

but it cost too much and is over kill for your needs

[galtbit]

Thanks again.  I guess the 900 watt from NE is fine.

my cable modem is plugged in the UPS, so internet does not go down when power goes down.

Power outages are mostly local and localised and not widespread.  Unless you live in a shithole or a third world country.  UPS FTW if you have frequent and short power cuts

Well, when there is a power cut in my area, it normally last a few hours.

Please tell me that your mining motherboards are set to Power on after failure, and your miner software is set to start with the OS?! (Pretty Please?!) It's usually a simple BIOS setting to change, and the auto-start is not hard to do in Windows or Linux.

Even if the power would go out, your miners would be back hashing within 2 minutes of the power coming back on.

And think about it: Are you really going to mine enough in those few minutes you're down to justify the cost of hundreds of dollars spent on a UPS?

You're better off running your gear through a decent surge protector (I run all my mining systems through a rackmount tripp lite) or even better, some type of line conditioner that keep the voltage to your components steady as well as providing surge/spike protection. Brown outs are much worse than any black out.
