Uninterruptible Power Supply

So I've been trying to find a good UPS since I'm pretty sure the constant brownouts where I live are what killed my last rig, but I can't figure out what the more expensive ones do. Some of them have fancy features like 'Pure Sine Wave systems' and other shit like that, but isn't the watt capacity all that matters? Any other anons have experiences with these things?

Pure sine wave just means more sensitive electronics should work with the UPS without issue.

It makes sure the output power is "clean" with little variance in voltage.

More sensitive electronics such as what? They call claim to protect computers from brownouts, both the ones with Sine Wave and the ones without it.

I've been using a modified square wave UPS for my server for 4 years and it's been though blackouts, brownouts, overvoltages, and power spikes perfectly fine.

for things like DLP, plasma TVs, and shitty PSUs.

With any modern quality PSU you should be just fine with a modified sine wave.

Expensive PSUs aren't any more tolerant of bad power than cheap ones are.

There are 3 basic types of UPS

low tier: modified square wave. Usually good enough for most things, but AC motors and some electronics don't like them.

mid tier: basic sine wave: these use a true sine wave. They are on the mains power unless there is an outage.

high tier: double conversion. these are essentially on battery all the time. they convert AC to DC, and then DC back to AC. When the power goes out there is 0 interruption due to switch over. However they can be a little loud because they are constantly converting.

>Pure sine wave just means more sensitive electronics should work with the UPS without issue.
No, plenty of things which have electric motors have problems with square waves. They are far from "sensitive" electronics and are about as dumb as you can get.

>It makes sure the output power is "clean" with little variance in voltage.
That is only double conversion UPSes, and my $2k APC Smart-UPS 3000-X HV with the NMC card doesnt even do this.

Whatever you get make sure you break it in by putting a laser printer on it and cycling it a few times.

I degauss my CRT on it.

Pure Sine Wave is a mark of good quality.
Don't buy shit without it.

How do you cycle it? I've never owned one before. I also don't have a laser printer.

he's just saying plug you laser printer into it and power-cycle the printer.

lasers suck down huge amounts of power on startup due to heating up the toner fuser.

protip: this can fuck up a lot of UPSs and it usually contraindicated in warning manuals

Wow. Thanks for the tip, man.

>$2k UPS
HAHAHAHAHAHAHA
ARE YOU SERIOUS?

You need the "Pure Sine Wave" thing if your power supply has active PFC (most expensive power supplies do). Regular UPSs don't work with active PFC power supplies.

I'm having trouble finding out what's pure sine wave and what's adaptive. The same model on new egg that claims to be pure sine wave appears to be adaptive sine wave on Amazon.

>3000 VA UPS with 2ms transfer time
>not costing $2000
Commercial stuff is expensive
I've dealt with UPS systems that cost millions, but it'll pay itself off the first-time the facility loses power

Why do you use a professional level UPS on a personal computer?

What are you on about, both links say "Pure Sine Wave."

Anyway, I have that exact UPS, bought it in August, 2015, it's been great so far and works well with my PFC PSU. Before that I had the 1000VA version of that UPS, bought it November, 2011, and it still works running my home server without problems.

CyberPower has been pretty good to me, all things considered.

Same model here, has saved my ass a bunch of times from brownouts and a couple short blackouts

Every time it switches to battery I regret not putting another one on my router so I could still have internet

If it's good enough for you guys it's good enough for me. Hopefully there's a deal on it soon.

The only problem I have with it is the extremely bright power LED, so if you sleep in the same room as the PSU and light bothers you, be prepared to use some tape or something.

One thing I do like about CyberPower PSUs is that you can turn off the audible alarm permanently, not all UPSs in this price range let you do that.

I do sleep in the same room as it, I'll put some electrical tape on it. Anything else I should know about these things? It's my first one.

Also, this question doesn't have anything to do with anything, but I shouldn't plug my airconditioner into the same outlet as my PC is plugged in, should I?

>fancy features like 'Pure Sine Wave systems' and other shit like that, but isn't the watt capacity all that matters
No. What you really want is a pure sine wave UPS. Those fucking square waves are worse for your shit than brownouts are.

Do these things protect against all voltage dips or are they not that fast?

>Anything else I should know about these things?
Not really. Well maybe the fact that even though it has 10 outlets, only 5 of them are on the UPS, the rest are just surge protected.

Also, the outlets are close together, so buy some of these if you want to connect stuff with those stupid power bricks:

>I shouldn't plug my airconditioner into the same outlet as my PC is plugged in, should I?
I wouldn't. Depends on the A/C, really. Outlets are generally rated at 15A and A/C can be electrically noisy.

>ARE YOU SERIOUS?
yes

Because I can afford nice things? Because consumer grade UPSes have tiny inverters in them, whereas mine supports 2700 watts? My 120V UPS is a APC BackUPS XS 1500VA and the inverter in it only does 865 watts for comparison. And the shit which is connected to it costs far more than the UPS did? I also have a pair for 2U 30 amp APC switched PDUs, one 120V and another 208V.

>I can afford
Didn't read past here. Confirmed more money than brains.

3kVA bitch.

Do you think this helps your case? Lmao @ u.

My case was previously made if you bothered to look at my previous pic. My consumer grade APC 1500VA - which i'm pretty sure is as big as it gets for consumer grade, cant even support a single computer on it because as I said, consumer grade UPSes have tiny inverters. This ignores things like runtime.

you forgot to mention your fucking Quadro render cards.

faggit

they're not quadros, just EVGA GTX 980 SuperClocked

bls resbond

jesus fuck I can only imagine the noise

Double conversion UPSes do, but they're expensive and you wont find them on consumer grade gear.

Its not that bad unless im playing vidya, then the GPUs get loud

>Double conversion UPSes do, but they're expensive and you wont find them on consumer grade gear.
So this won't protect against those split-second light dimming deals? Those are the ones I deal with the most. In that case, what can I do to protect my PC without spending three thousand dollars?

>So this won't protect against those split-second light dimming deals?
It depends on the model, on my SmartUPS you can configure (to a certain extent) when it will switch to battery during a brown out. If pic related isnt good enough for you then you have to look at double conversion UPSes.

>So this won't protect against those split-second light dimming deals?
yes it will

double conversion means that you are always running off DC. It's converting AC to DC, and then DC back to AC. You are always on battery, and there is no cutover time.

What the fuck could you possibly be doing at home that needs ~800W?

I already posted a pic of my ESXi box pulling 900 watts by it self with the 8x HDDs idle. I have that 2nd server, a Cisco Catalyst 3750E and a pair of Cisco Aironet 1140s also plugged in to it.

That doesn't answer my question. It only shows how much money you spent.

What could you possibly be doing at home that requires 800W+?

>What the fuck could you possibly be doing at home that needs ~800W?
800w isnt that much

its not that you draw 800w all the time, but things can spike up, like when you power up a system. you need some headroom. I try to run my UPS less than half max capacity.

>So this won't protect against those split-second light dimming deals?
Yes it will. Your PC certainly wont shut down from it, and anything else a good PSU on your computer can deal with.

>What could you possibly be doing at home that requires 800W+?

shitposting on 4chin

>What could you possibly be doing at home that requires 800W+?
Playing vidya and having ~40 VMs running at once.

>Videogames
Won't hit 800W.
>40VMs at once
Why?
If you're trying to disprove what I said earlier, you're failing.

Sorry for being unclear, I meant the CyberPower CP1500PFCLCD on amazon I linked to earlier. What's a daily occurrence where I live are, like I said, split-second light dimming dips in power. I guess they don't affect the typical PC but I'm pretty sure they ended up fucking up my big boy over the course of three years. This thing's the only thing I can think of to protect my new rig but I just can't afford one of the three thousand double converter quasi-generators like this dude has.

>Won't hit 800W.
The dual GTX 980s are a significant portion of the power consumed

>Why?
Because I work in IT and have a home lab?

>This thing's the only thing I can think of to protect my new rig but I just can't afford one of the three thousand double converter quasi-generators like this dude has.
lurk ebay for a 10-20 year old model and replace the batteries in it. you dont even have to always replace them all depending on how they're wired.

About $730 for a 1500VA double conversion UPS (good for about 1200 watts)

>I work in IT
answers everything I need to know about you. Thanks.

My old PC didn't shut down from them, I just think they ended up doing damage over a long period of time. I'm pairing this UPS with a EVGA SuperNOVA NEX 750W 80+ Gold Certified Fully-Modular ATX Power Supply which is going to be PSU for my new rig.

that's because you have a good psu. how does it do at 75% load?

Thanks ma-
>only one left in stock
>was hoping to score it for a deal on cyber monday
Oh shit. What's the noise on these double conversion types like?

Probably loud because the inverter is always running.

You'll be fine.

I have tons of voltage dips and brown-outs and I have been running on the same Corsair AX850 since 2011.

>What's the noise on these double conversion types like?
>Probably loud because the inverter is always running.

I have one of these at work. definitely not silent. there is a constant hum of the fan, but there is also a 'clicky' whine from the inverter.

It's not super loud, but I wouldn't want it near me work area.

With what UPS?

First a 1000VA CyberPower and then I upgraded to the 1500VA one in 2015.

I'm

I run a shit tier square wave APC 1500 XS.
I've replaced the batteries more times than I can count.

It generally works, but sometimes it doesn't hold up.

But at least it's silent most of the time.

Thanks. I'm probably gonna stick to that one, although who the Hell knows. Depends on what it looks like on cyber monday. It shouldn't be this goddamn stressful to just have a thing to play videogames and store japanese pornography on.

>that carbon footprint

>tfw yours doesn't tell you how much carbon you use

>tfw yours doesn't tell you how much carbon you use
ORLY

>22 cents per kwh
holy shit

We have tiered metering
First tier is 16¢
Second tier is 23¢
Third Tier is 29¢
I used about 80% of my first tier allotment. I was paying 16¢ per kWh
My whole bill last month was $44.37 including all tax, fees, feed the children, etc.
I put it at 22¢ because I wen't into the 2nd tier once.
It's just a rough estimate.

>We have tiered metering
that's awful. i pay $35 for unlimited until i hit 5k kWh. Then I pay $49 until 20k.

>that's awful. i pay $35 for unlimited until i hit 5k kWh. Then I pay $49 until 20k.
what?
I used 251kWh
My bill was $44.37
That's less than 1/10th the price.

I've been thinking about investing into getting a UPS myself. My server currently has a 550W psu and ideally I'd like to have it, plus a NAS, my cable modem, and 8 port switch all on the ups. Everything is in my basement so I ain't to worried about noise (unless it's like a vacuum cleaner) or heat. Severe power outages are rare but sometime the electric does flicker, least long enough for my clocks to reset. If it comes down to it, I can drop the NAS cause I only power it on once a month to do backups of my server.

I wanna fit in :c
1/2

wait waht
ugh
too many k's

5000 kWh?
you must live near a place with tons of hydro electric

2/2

i have untiered usage, and unlimited usage, for $35 until i have used 5,000Wh in a 12 month period.
then i pay $49 for the same until i have used 20,000Wh.

That's really cheap power
you must live in a wet area near hydro electric plants.
Probably pacific northwest or something.

i live in ohio kek.

top 3 sources of power comes from
>coal
>natural gas
>Nuclear

With Biofuels and crude oil neck and neck for fourth.

I live across the lake in Ontario right now to the major hydro electric plants and I average over $200 a month in electric bills.

Gotta love getting jewed.

yeah cheap ohio coal
must be nice

Here in Kalifornia, social justice wouldn't permit that

>I average over $200 a month in electric bills.
what the fuck? how?

>Here in Kalifornia, social justice wouldn't permit that
how much do you pay for internet? i live in one of the three major cities here and i pay $70 for 20/3 internet unless i want to get DSL.

How many kWh do you use?

I average $300-400.

House of 5 though.

10/100Mbps [s]Time Warner[/s] Spectrum cable

>I average $300-400.
how many kWH tho?

10/100Mbps Spectrum Cable $50/mo (internet only)

4-5,000kWH

>4-5,000kWH
a month?
Holy shit that's 33% more than what I use in a year.

Here in Hawaii we pay 35¢/kWh.
I want to leave.

Wow we are at $0.0868/kWh

Well family of 5, 4 desktops, 2-3 laptops, phones, lights, electric oven/range, electric dish washer, electric dryer and washer, 2 50" TVs, 4-5 PC monitors, etc.

Shit adds up. We also have electric heating and cooling.

I've got a server, monitor, modem, and 2.1 speaker with amplifier on this. Brownouts and random power spikes happen often where I live and the APC Back-UPS Pro 1000 I use has worked flawlessly since the day it was plugged in.

I've run graphics benchmarks as well as Prime95 and switched off the breaker midway into the run with fans going full blast. Estimated runtime was 5 minutes, and I have it configured to hibernate after two minutes on battery power.
