Suggestion for the best VALUE UPS (Uninterruptible power supply)

tonibello · Feb 20, 2016

Dears,
after breaking a the PSU and the MB for somehow reason I can’t understand I ask for the best VALUE UPS I can buy here in Italy too. I don’t want to spend a fortune. What do you suggest ? Please send me the links. I hope this part is available in my country too. Nor Newegg neither other wide electronic websites available here !!!

My build already DONE: http://pcpartpicker.com/p/ctb3qs with seasonic X-750 + PNY Nvidia Quadro K2000 (not coupled yet)
+ 2 monitor Samsung 24” and couple USB 5 lug hubs, external HD, and a LAN switch

Thanks for your suggestions.

tonibello :

You must list the video card in your build. The Xeon you listed has no iGPU.

turbopixel · Feb 20, 2016

Xeon processor (like noted above) does not have an integrated graphics unit. If you don't buy a graphics card, then you need a different processor with iGPU, like the i3/5/7 series. And you can't overclock Xeon. I myself have a Xeon 1230v3.

Looks like you want edit videos, right? Gaming seems not to be your destination. The processor is very expensive.

tonibello · Feb 21, 2016

Sorry to everybody. I added the GPU at the list !!!
Budget around 100EUR

tonibello :

When you edit the parts list it changes the permalink. You have to update the link to the build so we can see the changes.

Isn't the 5820K cheaper and much faster?

Vic 40 · Feb 21, 2016

kwa-e :

It seems that he already has the cpu,only motherboard and psu are replaced.

tonibello · Feb 21, 2016

you are going on the wrong way to answer !!! My question regards UPS !!! The rest is already parto of my Workstation http://pcpartpicker.com/p/ctb3qs ! No commenti on this . Only UPS suggestion

Vic 40 · Feb 21, 2016

Still no gpu in that build.

tonibello · Feb 21, 2016

Wrong statement

Vic 40 · Feb 21, 2016

tonibello :

Uhm ...what is?

for a psu something like this should do fine,

read the original question, please

Vic 40 · Feb 21, 2016

Ah you really need an UPS not psu,well honestly don't know about that.Could look at the top two in the next link,should provide enough for the pc,

the Powerwalker VI1200 seems to have the longest time it will keep the power going if i'm right.Maybe a moderator here knows more about this,can ask for some help,will PM him (done).

What is your UPS budget and where can you order from? Amazon Italia?

We also need to know the model of your power supply so we can determine if the UPS is going to be compatible because they do not all have compatible wave forms.

tonibello · Feb 22, 2016

Budget : arund 100EUR. Amazon Italia or trovaprezzi !
Power supply seasonic X-750W

tonibello · Feb 22, 2016

Contacted this brand power walker from germany. They answered to my question in this way:

during standard operation in line mode I also think that 480W might still be good enough.
Critical point is when during power outage UPS switches to battery mode.
Here the switching behavior of the APFC power in interaction with the inverter circuit waveform defines how much buffer is required.

Besides of the VI800SW (800VA/480W) all other model you mentioned have a simulated sinewave (single pulse wave) output in battery mode.
In this combination the APFC power supplies drains much more power from UPS during switching process.
Therefore we suggested models as mentioned before.

The calculation you suggested is valid for UPS with pure sinewave output in battery mode.
Here the reaction of the power supply is different, switching peak is lower and does not require that high buffer.
Models that fulfil this requirement as below.
As price seemed to be one of your key criteria and the as models below are more expensive then the bigger units with simulated sine wave
these models where not considered for offer.
Datasheet - PowerWalker VI 1000 PSW
Datasheet - PowerWalker VI 1000T-HID

In your specs it shows a Sea Sonic 750W 80+ power supply. This is an APFC power supply. This type of power supplies create switching peaks
that back feed to UPS while UPS switches to battery mode (especially for UPS with simulated sinewave output in battery mode).
This peaks can in worse case be 2-3 times higher than the real power consumption of the connected device and even higher that the rating of the PC power supply.
If UPS chosen is too small then in case of power outage the UPS might detect the peak from power supply as over load and cuts the output.
To be on save side we recommend to use UPS with some safety margin.

Slightly cheaper than the model offered might be VI 2200 or VI 2200 LCD but prices are still higher than your suggested limit of 110€
Datasheet - PowerWalker VI 2200
Datasheet - PowerWalker VI 2200 LCD

If 110€ is you overall limit I’m afraid we don’t have a model that is below this price and still fulfills the power demand of the PC.

That explanation sounds 100% accurate to me, and is probably a good guideline to go by.

I think it is unlikely you are going to find a pure sine wave UPS of the capacity necessary, within your budget.

tonibello · Feb 22, 2016

You're right ! The request was: which do you suggest according to my budget ?

Darkbreeze · Feb 22, 2016

There are no UPS units within your budget that I would recommend. Those that are within your budget are a false sense of security and a waste of money.

Darkbreeze · Feb 22, 2016

Let me ask you this. What is the REASON you are wanting a UPS? Protection from power spikes and surges? Bad power grid in your area? Voltage conditioning? Or protection against losing data if the power happens to go out?

tonibello · Feb 23, 2016

1) Protection from power spikes and surges
2) Voltage conditioning

Blackout and brownout rare ... only during network works !

tonibello · Mar 6, 2016

Need help

Darkbreeze · Mar 7, 2016

As I said before, what you want can't be found within the budget you've outlined. It just can't. This is the best unit in your market that I see, that is still within your budget.

tonibello · Mar 8, 2016

what do you think should I need to have a perfect fit ? How much should I spend and for what ?
Obviously available in the European market (possibly with schuck plugs or french !) !!!

I am not familiar with those terms. Perhaps you would have more success seeking assistance on a site closer to your location. Like this:
