I just purchased a new Alienware gaming rig. It has a 3.9ghz Hexa-core processor, 32 Gb of 2133mhz RAM, a 128 Gb SSD, a 2 TB 7200rpm drive, and dual Nvidia 780 GTX 3Gb DDR5 graphics cards. It is connected to a 1920X1080 23 inch Dell display, a Razer mechanical gaming keyboard, Razer DeathAdder mouse, and 2, 50Watt Logitech THX certified speakers with a 100Watt sub-woofer. The PC itself has a 1500Watt power supply installed.

I want to get an Uninterruptible Power Supply with pure Sine-Wave, but am not sure what va or watts I'll need. Can someone help me choose and perhaps price out the cost of an appropriate UPS?

Thank you in advance for any assistance.

I'm not an expert on ups's, but I believe apc and cyberpower both make decent ones. The psu rating isn't as important as what you're actually drawing from it. It may be rated for 1500w, but you may only be pulling 900w (guessing, since I don't know what your system is actually using.) Most ups's have both battery backup plugs and standard plugs with surge protection. I'd plug the speakers into a standard surge plug (sound isn't necessary to use the pc) and the monitor and tower into the power backup plugs. Overclocking will also determine how much power you're pulling through your psu.

If I had to take a shot in the dark, I'd say a ups close to 1000w. I don't know what your budget is, once you get into the bigger ups's the price...

This one is pure sine wave, cyberpower 1050w for around $350. http://www.newegg.com/Product/Product.aspx?Item=N82E16842102145

The reason I suggest going up from say a 600 or 700w unit is this - ups backup power often says x amount of minutes of battery runtime at x amount of power draw and they like to feature the higher battery run time. The unit I listed will run for around 2hrs - at 100-200w power consumption. At 300w only 50min, at 500w only 25min - and at 700w (closer to your reality for your system) only 15min of power. Should you be drawing 800-900w (worst case scenario, gaming etc) then you'll more likely only get about 5-10min of battery time before you run out. You don't want 2min of battery to haul buns and have to shutdown in a panic. 5-15min gives ample time to properly close down even a large number of applications and get your pc powered down safely.
