New system - UPS?

[NicShadow_IT]

Hello.
Im planing to buy a new system (Alienware R16).
The PSU is a 1000W.
Advices for a UPS?

Unless you have frequent brown outs (short period power outage or flicker) you don't really need a UPS just a good surge protector. It will cost you a LOT less

PSU does not really matter....load does.....you need to know how much the system is drawing at full load and go from there based on how long you need up time to shut down the system.....they are really for safe shuts downs in a power outage....not keeping the system running for a hour in the middle of a storm.....

This is the one i use for my 13900k / 4090 oc with a 1200watt psu
regardless which one you get make it sinewave

You're buying a DELL ? Hmmm...
Well, Cyberpower is now the leading brand. I bought the 1500VA for my system (OLD).
A UPS normalizes current and takes out brownouts, not just surges, but the battery gives you that nice "Save all your ♥♥♥♥ & shutdown" in 5, 10, 15min. (depending on usage).
When batteries run out, buy replacements not original, much cheaper. Mine are quality controlled mfg. & running for 4 years now.

ups i not designed to keep a system running for hours or days

its designed to keep the system running long enough to shut down safely

99.9% of the time, windows can recover from power loss with no problems
it will run scandisk and fix any file system errors, things being written at power loss may be corrupted

most have a usb or serial connection to tell the pc to shutdown when power is lost

Well unless you will actually be using 1000w it doesnt really matter, but something in the 650-1500VA range should do the trick. You want enough power so you can safely shut the PC off, not to keep it running.

After which you can then use the UPS to power some lights and your phone chargers if needed.

I have a 900w UPS for my main PC which is set to automatically turn the PC after a few minutes of no power if i dont do it myself, a 360w UPS for the downstairs PC and USB lighting, another 360w to keep the security cameras powered for up to 3 hours (recently tested) which i may get another to double it to 6 hours, and another 360w to power whatever else, like a fan or w/e. The 360w UPS's i got from walmart for about $60-70.

And then i have an insane amount of power banks and DIY power banks to power 5v and 12v lighting, in addition to some Craftsman 20v batteries with 150w DC-AC Inverters to do the same thing, and also for powering smart TVs.

But yeah, you dont have to get an expensive UPS, just get one that'll do the job.

I haven't anticipated saying this in the span of forever and ever but at least for the moment, the Alienware Aurora R16 is looking like it might actually be okay.

I'm not going to comparative shop super hard since that's not the point of the thread, but they're not using the R9-R15 case design that stifled the thermals so badly anymore and at the current sales pricing of $1700 for a 13900k and an RTX 4070[www.dell.com] configuration isn't looking like no-deal price, for a prebuilt. It maybe even looks like Dell is giving you A.T.X. standard parts, though maybe means I am not sure.

I mean, NZXT is charging it's $1750 for an H6 flow with a 4070 and a 7700x[nzxt.com], and Cyberpower has the audacity to charge $1665 for a 14700k with a 4060 ti 8gb[www.cyberpowerpc.com]. Out of the three configurations, Alienware's looks the most appealing for out of the box performance. To be fair to NZXT and cyberpower though, that looks to be baseline pricing rather than with a $350 discount. If the Alienware was at full M.S.R.P. of $2050, you could do better.

I mean, LGA 1700 is having stability issues with some of its i9 processors, I'd still rather build it myself for the sum that would save me, and Ryzen 9000 C.P.Us. are being released at the end of the month, so the pricing is likely so low (for an alienware) because they're trying to clear out stock. Nevertheless, if somebody put a gun to my head and ordered me to buy myself a $1700 prebuilt desktop computer today, the Aurora R16 can't be dismissed right out of hand.

Of course, I'm only judging based off of the $1700 configuration.

I don't think Cyberpower maker of UPS and Cyberpower maker of gaming PCs are the same company.

First of all, thanks for the replies.

About the Dell... Well in the past I was used to go to a local dealer, arrange a configuration, and let him to build a custom PC. But now are 5 months Im waiting for a quotation, so I decided to give up with him and buy a pre-built computer. :p Why Dell? I searched the net for "Best gaming PC", and in 10-15 sites the most nominated was Alienware R15/R16. I opted for a R16 just a bit pumped up :p

About the UPS, I know that an UPS is not a generator, I would like to buy one just to "protect" my investiment (new PC) by eventual power supply issues...

Thanks again for all the replies. :)

ups will not protect the system from a poor or overrated psu, that is not its job

[NicShadow_IT]

Sorry... I was meaning... Just power? IN power?

This is the one I have. No complaints, except it's heavy. I think that's most if not all UPS though.

psu should have its own protections
a good power strips can have mov that should blow when it goes over voltage, but most psu should be rated for 110-220vac and will trip at a higher voltage than a 110v power strip or the ups

undervolt is also ok on psu, most will run fine at around 50-80v just pull more current to make up for the lower voltage

as for line noise, the filtering and main switching circuit will filter that out
if the psu is good

a ups will connect mains to its outputs while power is available, and switch that off and use its battery to produce its output when power is lost

for switching power supply, square wave is fine, or even better than sine wave
sine wave is only needed for transformer power adapters,
switching psu will use diode bridge to make dc high voltage and chop that at a much higher freq for it internal transformers

if you really want to get nuts you can buy a used server UPS unit for cheap with dead batteries and put new ones in it....I have sold and bought many over the years for as little as 50 bucks and then put new batteries in rebuilding the old rack packs.....

had a stack of these at one point i sold off for 50 bucks each to a coin miner......this is not my post just a idea of what could be around you for cheap if you look

Its obvious you are new with too much money. You dont need a ups you need a simple cheap surge protector...


Alienware and a ups, You couldnt make it up. Are you aware of the Intel problems? It would be cringe to buy a 14xxx cpu and a ups. Buy a 7800x3d and a $20 masterplug surge protector...
