UPS question! Need help!!

[Need Help_71]

Can a 750W PSU such as this one http://www.microcenter.com/single_product_results.phtml?product_id=0377236
be supported by a UPS that supports only 650W but for a short amount of time. The power goes out alot over here but there is full power back-up which takes 5 mins MAX to turn on. If the PSU is the only thing connected to the UPS, will the UPS be able to support it?? THANK YOU

PS: does the above mentioned PSU work on 220V sockets?

 

[aviral]

Yes,it will work and its on 100v/240v socket.

As the maximum output of your UPS will be 640W and your UPS is 650W it will surely provide 10-15minutes of backup time.

UPS link please?
Just to get UPS idea.

 

[Need Help_71]

It would?! Even though the PSU requires more wattage than the UPS provides? :S

Thank you for your assistance.
Didnt have a particular one in mind but here is a link:

Go with the 1st psu not this because it is not as efficient as the above one.

 

[Need Help_71]

but would this setup work then?

 

[aviral]

Yes,why not (if you are running on your cpu on UPS it will definitely work).

 

[aviral]

Post your system details?

 

[ko888]

Does your UPS output a stepped approximation to a sinewave or is it a pure sinewave when operating on battery power?

GTX 680 GPU
Intel 15 3750k
Cooler Master 212 EVO cooler
NZXT Phantom White Case
G.Skill Ares Series 8 GB
Western Digital Caviar Black 1TB
Asrock z77 MOBO

I didnt have a specific UPS in mind - but this one sounds good if you could recommend one that would be great!

an example....don't wanna go above 150 bucks for a UPS

 

[Need Help_71]

^^that UPS is pure sinewave

 

[aviral]

^^that UPS is pure sinewave

Just check out that will your psu requires a sine wave input or other type by google and you will know the answer by your self.

For a system using a single GeForce GTX 680 graphics card NVIDIA specifies a minimum of a 550 Watt or greater power supply that has a combined +12 Volt continuous current rating of 38 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

For a system using two GeForce GTX 680 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 750 Watt or greater power supply that has a combined +12 Volt continuous current rating of 53 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

The OCZ ZT Series 750W (OCZ-ZT750W), with its combined +12 Volt continuous current rating of 62 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 680. It is also sufficient to power your system configuration with two GeForce GTX 680 in 2-way SLI mode.

The Antec EarthWatts 650W (EA 650), with its combined +12 Volt continuous current rating of 45 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with a single GeForce GTX 680. It is also insufficient to power your system configuration with two GeForce GTX 680 in 2-way SLI mode.

If you're planning on running with two GeForce GTX 680 graphics cards in 2-way SLI mode in the future then choose the OCZ ZT Series 750W (OCZ-ZT750W) that you originally suggested.

For the UPS I would go with a CyberPower CP1350PFCLCD 1350VA 810W Pure Sine Wave:

If you're planning on only ever running with a single GeForce GTX 680 then you can still choose the OCZ ZT Series 750W (OCZ-ZT750W). For the UPS you can go with the CyberPower CP1000PFCLCD 1000VA 600W Pure Sine Wave that you suggested.

ok thanks so much!! I will choose the OCZ PSU
last question! the above mentioned PSU is 750W while the UPS supports 600W is that okay?

To be on safe side get at least 700W UPS.

 

[Need Help_71]

ok thanks

Using a single GeForce GTX 680 your system should be drawing less than 300 Watts from the power supply while you're gaming.

Taking into account the PSU's conversion efficiency it should be drawing less than 350 Watts AC at the PSU's AC power plug.

You may want to have your monitor plugged into the UPS also.

So.....a 650/700W UPS would support both the monitor and the PC (depending on the monitor)?

Yes. The best choice would be an LED back lit LCD monitor for its low power consumption. A good LED backlight LCD monitor usually draw less than 30 Watts from the AC wall outlet.

oh ok I shall look into that. The only thing I don't understand at the moment is how a UPS that supports say 650W can keep a 700/750W PC running for even a minute? :S

That's because the PC isn't drawing 700/750 Watts from the power supply. The power supply does not output 100% of its labeled power 100% of the time. It only provides as much as the system needs at any given moment.

 

[Need Help_71]

ohh ok I understand Thanks so much for your assistance!

 

[wendyhrd]

i don't think so, bcs the best way for UPS is using 60-80% capacity of UPS, the UPS is 650w, so it's better for you to use at most 520w, means the output support most is 520w, so the load should be less than 520w, or UPS will be overloaded, i don't know if your UPS has overload protection or not
