I need a UPS for my new 550 W computer power supply. Do you know which UPS will be best for a 550W computer power supply. Nothing very expensive either. I just want a UPS that can keep my computer powered on for 10 to 15 minutes til I shut it down during a power outage in my locality. Please let me know. Thank You.

A 550W PSU doesn't mean your system will draw that much power from the UPS; please provide a list of components including external devices like the monitor that will also be connected to the UPS. What's your budget and are you looking for a pure sine wave unit (much better for the PSU)?

There is a Dell IN1910N flat panel monitor, a Canon pixma mp480 printer cum scanner and Dell AY410 speakers connected as peripherals to the computer. My budget is $128. I want something that will be the best fit for my new Silverstone ST55F-G 550W power supply . If a pure sine wave unit is much better for the PSU then for sure I want to go for it. Thank You.

Meets your budget, but it won't run for 10 minutes at full system load: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
This one would be a bit better, but it exceeds your budget: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

These are becoming too expensive more than $200 with shipping as I live outside the USA in India. Can you please tell me if this a good UPS and also does it have pure sine wave - APC Back-UPS RS, 1000VA, 230V. It is a 600W UPS from APC. This is available locally to me. "Thank You very much". APC Back-UPS RS, 1000VA, 230V, INDIA

Best solution
You only need the PC and the monitor connected to the battery backed sockets since they are the only critical components needed to confirm a proper shutdown during a power interruption event. The total power consumption of those two components should be less than 200 Watts if your system is the Dell Inspiron 545 configured as shown in your sig.
The SilverStone Strider Gold series 550W (ST55F-G) is made by Enhance Electronics. Its APFC circuit should have no problems operating on a UPS that outputs a Stepped Sine Wave when operating on battery backup power.

Thank You very much.
How are these APC uninterrupted power supplies
a) APC Power-Saving Back-UPS Pro 1000 with LCD, 230V and
b) APC POWER-SAVING BACK-UPS PRO 1000VA WITH LCD WITHOUT BATTERY, 230V.
They are 600W. Will this be sufficient for my SilverStone Strider Gold series 550W (ST55F-G) power supply and my Dell Inspiron 545 configuration. I also have the following peripherals.
1) Dell IN1910N flat panel monitor,
2) Canon pixma mp480 printer cum scanner and
3) Dell AY410 speakers.
Please do pour your knowledge on it. Thank You very much.

What do you mean? Line Interactive or something else?
https://www.apc.com/products/resource/include/techspec_... is Line Interactive. Would you really save money if you bought the batteries separately?

I mean some thing else. I read an article on UPS at hardwaresecrets.com. It says series on-line UPS is the best. They have no interruption at all. An online (a.k.a. double-conversion) UPS is more expensive than a line-interactive UPS due to the more robust AC-to-DC battery-charger/rectifier circuit needed for that topology.
You were already complaining about budget.

OK so will the APC 600W UPS be right for my SilverStone Strider Gold series 550W (ST55F-G) power supply. Thank You.
It should work based on your system's power consumption requirements.
As always, no PSU or UPS manufacturer will guarantee compatibility. They will always recommend that you test the combination to make sure that it works for your specific configuration.

Like I said before, the 300W UPS wasn't powerful enough. With a new UPS that's twice as powerful you shouldn't have issues. My APC Smart-UPS are powered on 24x7; the only issues I ever had was with batteries that were too old and could no longer keep their full charge. It's up to you to keep your PC powered on all the time or not. Unlike a server that normally has to be available 24x7, a PC should be shut down or put in sleep mode (my preference) when not in use.

It doesn't matter if your PSU is 550W or 1200W; what's important is how much power it draws from the UPS (or the wall outlet). At peak your whole system, including the monitor and other accessories, may draw 300W, but it should be less than 150W at idle. Presuming 85% PSU efficiency, the system may draw up to 350W from the UPS. Presuming 85% efficiency at full load, if your PSU was really drawing 550W (550/85*100 = 650W), then a 600W UPS would obviously be overloaded since all components would draw approximately 700W; if there was a power failure, the UPS would simply shutdown to protect itself.

That model for India has no internal battery; you'll have to buy an external battery system. The UPS is less expensive, but you sure won't save money and you'll have 2 enclosures (one for the UPS and one for the external battery system).
If you buy the unit without batteries, then you also need to buy http://www.apc.com/products/resource/include/techspec_i... Should you decide on that expensive solution, double-check with APC to make sure this is the correct part number. I found one in India for 6,700 INR.
