Which UPS to use(also rating) for 1300 watt to 1500 watt PSU

What power is your rig pulling. PSU size doesnt matter.
You can just add up the max power draw of each of the components, this link does it for you though. http://support.asus.com/powersupply.aspx

Thats for a PSU, not a UPS

It's surely still applicable? The UPS would need to be able to deliver the maximum watts needed to power the PC surely?
oh, my bad :/ surely it should still work for his purpose though? I mean it still gives you the total power consumption of your device (kind of). In the worst case it gives you a ballpark figure, no?

No, because you have the efficiency, so a 750w PSU pulls nowhere near that from the wall, a server engineer I know says that on average a 500w PSU requires a 1000VA UPS, and that lasts for 6mins, but another thing is, are you going to have your screens plugged in too?
Thank u Ozydious
What i can see there is calculating the wattage
Which i already mentioned 1300 watt to 1500 Watt (not exact calculation)
for calculating current; 1500w/220v=6A to 7A
(I dont know that i calculated it right or wrong):huh:
My question not about PSU, but about UPS
In my area Power is not so stable
So, I need a UPS(preferable APC, u guys may also give suggestions)
but what is the rating of the UPS(I dont need 6 mins, but at least 2min definitely)??
thank u again, u people just awesome... :worship:

You might be able to rent a power meter from a hardware rental store if they have them, or you will have to buy one. Then max the pc out and see what its pulling from the wall. Then add another 10% on incase the power meter is inaccurate (A 16 quid one won't be bang on). You will then get the next(round up) nearest rated UPS.
Otherwise you will have to make a guess and it will have to be an overestimate.

Use the power factor in the equation.. you have the wattage and voltage and therefore the amps. The power factor is part of the PSUs specs.

OP was asking about getting the correct size UPS in terms of the been about the power the system, not how long. The length of charge will depend on the UPS itself, most say how long they will provide power for at max load.
