I currently have the following UPS (with AVR): http://www.cyberpowersystems.com/products/ups-systems/o...

In my room (with ONE outlet T_T), I want to plug in the following (not necessarily into the UPS.. I can use the other plug with a standard surge):

• Computer Build:
CPU: i5 2500k - OCing to 4.0
CPU Heatsink: Corsair H50
GPU: EVGA GeForce GTX 570 HD 2560 MB
RAM: G.SKill Ripjaws (2x4GB) DDR3 SDRAM 1600
MOBO: ASRock P867 Extreme4 (B3)
PSU: Corsair AX750 (CMPSU-750AX) 750W
BD Drive: Samsung Black 12X BD-ROM 16X DVD-ROM 48X CD-ROM SATA
HDD: Western Digital Caviar Black 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s
Case: AZZA Solano 1000 Black/Black Japanese SECC Steel/Metal mesh in front ATX Full Tower Computer Case

Other stuff:
NIC: Intel PWLA8391GT 10/ 100/ 1000Mbps PCI Desktop Adapter PRO/1000 GT
Wireless Adapt Trendnet TEW-687GA Ethernet Port Wireless N Gaming Adapter
Inputs: Logitech Wireless mouse and keyboard
PS3 Game controller

• TV: LG 47LH90 100V-240V, 50/60 Hz (http://www.lg.com/us/tv-audio-video/televisions/LG-lcd-...)
• Sony Sound Bar HT-CT 100 (http://www.tigerdirect.com/applications/SearchTools/ite...)
• HP C6150 Inkjet Printer (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00...)
• Trendnet 450 Mbps Wireless Gaming Adapter (http://www.trendnet.com/products/proddetail.asp?prod=22...)
• Playstation 3 (http://us.playstation.com/ps3/techspecs/160gb.html)
• HD TV Antenna (http://www.monoprice.com/products/product.asp?c_id=109&...)
• Small lamp (never on)
• 2 x Box fans
• Apple Macbook Pro 15 inch
• iPhone
• Gf’s Blackberry

Is my current UPS sufficient? or should I get something with a higher VA rating? I don't necessarily need to be running EVERYTHING should the power go out.. (like, I'd never have both the PS3 and my computer on at the same time, since the TV is used for both).

I really just need something that could regulate the voltage when these or some combination therein are running.
Thanks!

Your current UPS is 330 watts - the PSU in your computer is 750 watts.

Normally, I like to size the UPS to 70% of the computer PSU + the monitor power. This will come to 750 x 70% + 50 = 575 watts (or 600 watts UPS).

Get a 600 watts UPS.

Another question:
Does the Wattage of the UPS matter if I'm using the UPS more so for its AVR aspects?

Answer : Yes
The wattage of the UPS is how much its AVR can output, not what its battery can support. If you exceed the UPS wattage .. well some units can tolerate a small overload, some shutdown, some go into bypass, and others burn out.

You probably should not use the UPS with this system, its not donig much good anyways as with your load you'd be lucky to get 45 seconds runtime; Plus your Cosair PSU probably has an AVR built in.

well, the computer is currently out of commission. I'm waiting on a new PSU.
I guess I'll look into a higher wattage AVR UPS in the meantime.

Thanks again for your help.

HOPEFULLY, it was just a combination of the UPS and PSU that caused my initial problems.. but I'll update once I get the materials and run the test.
Thanks!
