Iv tried cheap brands that i can find locally, but none of them are able to hold my computer. Can anyone recommend a good brand and model?

My power supply is 650, and the average consumption of my pc is 250.

Will give more info if needed, thanks!

We need other relevant information like how long you want the UPS to hold up is very important. APC makes some good UPS's. The higher the VA rating the longer it will hold up. I believe a 900VA unit is capable of 500-550 watts.

I just need it to hold up long enough to shut down, thats all. So i guess 2 - 5 minutes?

Its been awhile since I bought a UPS.
This can help you choose one that will be capable for your system.

I am not sure of your monitors wattage but I am tossing 70 watts there which is at the higher end. It suggests a 650VA unit
http://www.newegg.com/Product/Product.aspx?Item=N82E168... Will work, it is over the suggested rating giving you room to grow and will allow more time if your system is under load, it will also give protection on coax, telephone and ethernet.

This unit http://www.newegg.com/Product/Product.aspx?Item=N82E168...
will last 17 minutes at 270 watts. Which will be more than your needs, but it only capable of a maximum of 540 watts, so if your computer load goes above 540 watts the UPS may shut down to prevent damage.

Edit: I see you choose one, unfortunately that link doesnt work so I cant see. Did some modding of the link, that one will work for you fine. Its cheaper to, nice find. for some reason that didnt show up in my searches

Even a relatively cheap UPS should be able to hold up a 250W load for a few minutes. Perhaps your issue is that you have an Active PFC PSU, which does not like the simulated sine waves that most cheap UPS units produce (and will immediately shut down on a switch to battery).
Supposedly, Cyberpower now has a line of relatively inexpensive units that produce a wave that, while not quite a true sine, will work with Active PFC PSUs. If not, your next choice is a Smart UPS from APC. Those are a lot more expensive, but do produce a true sine wave.

That wasent my link lol, someone else posted it =D. Those look fine, but i cant buy from there, they dont ship to europe (i wish they would :(  ). I was going to buy one from overclockers, which is where i usually buy from. Here, look at this list:

I dont think they make my model of power supply anymore. Its called "Seasonic S12 600W Silent ATX2.0 Power Supply". Is this an Active PFC PSU? I tried two types of cheap brands and none of them held my pc up for even a second, so i finally decided to take a hit and import one (expensive as hell).

Thanks for the replies.

You made the right choice getting a Seasonic PSU
Is this your PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

It says it has an Active PFC.

In terns of watts that UPS you edited in is pretty good. APC makes good UPS's. But from what jtt283 wrote it may not work well with your PSU since it has an active PFC. From personal experience my PSU with Active PFC worked fine with my old belkin UPS.

It seems that http://www.overclockers.co.uk/showproduct.php?prodid=UP... is the only one that jff283 said will be guranteed to work with Active PFC, which may be what you are looking for. It is more however more expensive.

Something to remeber with all UPS's batterys will die after awhile. When mine stopped holding a charge I purchased some new batteries online (heck of a lot cheaper than replacing the unit)

So where it says "Smart-UPS", it means its compatible with Active PFC? And what is Active PFC anyway? Is it a drawback from old power supplies?

Thanks.

As I understand it, Active PFC aligns the current demand with phase of the incoming voltage waveform, basically making the equipment look like a simple resistive load to the power grid. It doesn't make any difference to you, the consumer, but it matters in terms of power grid capacity and planning. In some part of Europe, electronic equipment is required to have a PFC circuit. PSUs that do not have active PFC also have to use a little voltage switch to adjust from 110V-120V to 220v-240v.

I would have to go wth jtt283's explaination, I dont know to much about active PFC to really answer the question well, best I can really do is point you to wiki http://en.wikipedia.org/wiki/Power_factor#Active_PFC
In my opinion you probably dont need a Smart-UPS but it would be a safer bet. The one you linked on that site should work fine, but I cannot be 100% certain.

I came across this in a search
http://arstechnica.com/civis/viewtopic.php?f=7&t=136404
Basically saying cheaper UPS's like the one you linked earlier, will work fine with a quality PSU (ie: seasonic)

The Cyberpower model is very reasonably priced, assuming it works (I've not tested one personally, but I'd be inclined to try it).
I can tell you that my Delta-built Antec SG-650 shut down immediately on a switch to battery on my mid-range APC Back-UPS ES 750, as did my wife's 500W Antec Earthwatts. That's when I researched and bought an APC SUA-750, which works perfectly on battery.
