Need a good UPS for a 550 W computer PSU.

[captaincandellight]

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)?

Edit: Bumping is not allowed in this newsgroup.

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=N82E16842102131&ignorebbr=1

This one would be a bit better, but it exceeds your budget: http://www.newegg.com/Product/Product.aspx?Item=N82E16842102132&ignorebbr=1

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".

On-battery Waveshape: Stepped Sine Wave

 

[GhislainG]

I presumed you were in North America because your budget is in dollars.

That UPS is not bad (I prefer the more expensive Smart-US), but it provides Stepped Sine Wave while on battery. Since you didn't provide a list of components, I can't verify if your PSU is compatible with that UPS.

 

[ko888]

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.

 

[captaincandellight]

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.

 

[GhislainG]

Absolutely. It should keep your equipment powered on for at least 10 minutes unless you are doing something that keeps the CPU and GPU running at 100% load.

 

[captaincandellight]

Are these the series on-line UPS.

 

[GhislainG]

What do you mean? Line Interactive or something else?

https://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=BR1000G-IN&total_watts=200 is Line Interactive. Would you really save money if you bought the batteries separately?

 

[captaincandellight]

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.

 

[captaincandellight]

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.

 

[captaincandellight]

I will have the monitor and the PC plugged in to a surge protector with all the other peripherals speakers and printer also plugged in to it. Then have the surge protector plugged in to the UPS. Is this configuration proper. Please do let me know. Thank You very much.

 

[GhislainG]

The UPS is a surge protector; therefore adding one is useless.

 

[captaincandellight]

I may need an extra surge protector if the UPS cable falls short. So if buy chance if I need an extra surge protector will that affect performance of UPS or PSU in any way. Please let me know. Thank You very much.

 

[GhislainG]

It won't because a surge protector does nothing unless there's a power surge; the UPS already provides that protection.

Thank You very much.

 

[captaincandellight]

After I finish a secession with my computer, do I have to switch of the UPS as well or do I have to leave it on. Please let me know. Thank You.

 

[GhislainG]

Why would you power off the UPS? A UPS should always be powered on to keep the batteries fully charged. My systems, switches and routers are connected to 2 UPS that never are powered off.

 

[captaincandellight]

Because I had a 360W UPS from APC which crapped out on me after being on contentiously for 1 month. The PC would only go in sleep mode when not in use.

 

[GhislainG]

It probably wasn't crappy, but it most likely was underpowered for your requirements. What do you mean by "The PC would only go in sleep mode when not in use"? The UPS shouldn't affect the PC at all; it's sole purpose is to protect it and provide power if there's an outage.
