[UPS] How much wattage do I need? (not PSU)

post #1 of 3
Thread Starter 
I am strongly considering purchasing a UPS to help protect my investments. I have narrowed my options down to PFCLCD models from CyberPower but I'm not sure of what wattage I would require.

The PFCLCD line offers 1000va 600w, 1350va 810w and 1500va 900w units, priced at 135, 172 and 205USD respectively. The manual for these models state that my draw should be no more than 80% of the units rated wattage. With that in mind, I would like to have the following plugged into it...

Battery/Surge
--AX750 powering a Z77XUD5H, 3570K, 2x4GB RAM, 3 HDs, 2 SSDs, 1 Optical, 2 HD6850-tier cards, USB keyboard/mouse and 6-8 fans. [psuCALC puts this at 550-640 watts depending on clocks. I don't bench however so I'm not sure how those figures pertain to me.]
--One LCD monitor that claims in its specs a maximum wattage of 55.
--One modem.
--One router.
--One additional HDD in an external enclosure. [It's a WD Caviar "green" though that likely makes no appreciable difference.]

Surge
**These items do not need to be connected to the UPS. If it's more economical to connect these to their own surge strip, then that's what I'll do.
--One receiver rated at 75w/channel, powering two bookshelf speakers. Volume never exceeds 40%.
--One 400w rated subwoofer. Volume set to 15%.
--PS3

Thanks and sorry for using you guys for info again. I've been spending all my free time the past few weeks going over every minute detail of the new setup and my brain is starting to melt as a result.

Also, if you use a UPS for your rig I'd love to know what wattage unit you're using, what you have connected to it and, should it display such info, what that draws during use.

I am using a APC ES 550. It is rated for 330W (550VA). I have my computer system with a 1000w PSU, surround sound, ps3, 32in LCD tv, 27in LED monitor, lamps, modem, and router. Everything that isnt super expensive is only running through the surge protector part.

When the power goes out I have about 30 seconds to save my work before my computer shuts down, which is plenty when im working on something important. Obviously when im gaming I would have maybe 10sec but im not going to lose any critical data.

It sounds like that 600w might be just fine for what you using.

The higher the va, the longer the time you have to properly shut everything down- so go with the highest rating you can afford.
