Buying a new UPS (no break)

[Caple]

Hi everyone.

Right now I have a 600VA UPS, where I connect my PSU, monitor, NAS and ADSL router. It always worked fine for me. But now I'm playing a little with HD editing on Premiere and it seems the UPS can't hold the demand.
My PSU is a 600W OCZ and I have no idea how much watts my computer uses normally. As my UPS probably holds about 300W, I believe the PSU is asking for more them that. The UPS starts to beep and the computer turns off.
I decided to buy a new one, around 1400 or 1500VA, but can't find a good price here. The other option would be getting a APC 1200VA UPS, that holds around 600W, and use it just for my PSU. Then I keep the 600VA UPS powering the monitor, NAS and ADSL router.
So... buy a new one for everything, around 1400 or 1500VA, or buy a smaller one, around 1200VA just for the PSU?

How old is your current UPS, or rather its batteries?

The amount of time that the UPS's batteries can keep a system running declines quite a bit after only a few years. I think I remember hearing that after 3 years, the amount of time they will power a system is halved.

Given the cost of replacement batteries, if the batteries in your current UPS are not fairly new, you should replace your current UPS with one that can run everything, unless two less powerful ones that can run everything between them are cheaper.

It has only one year. Maybe not a year yet.
I tried playing with a HD file today again and it didn't turn off. But now I was encoding a DVD spec file, not a bluray one (using the presets on Premiere). Seems like it sucks more power when encoding to HD.

I would buy the 1200VA just for the PSU and monitor. I can't think of a reason why you shouldn't give the NAS and ADSL router separate protection using what you already have, since the battery in your existing PSU is relatively new.

Yep.
That should be the less expensive way to go
I'll look for some good prices here and see what I get.
Thanx.

Most PCs draw around 130 - 150W from the AC line. I would just plan on powering the PC and the monitor and leave the rest to the AC line. A decent quality UPS in the 750VA - 1000VA range should give you about 30 minutes most times or maybe more. I'm assuming a LCD monitor. CRT monitors use a lot more power. I use a 600VA UPS and it gives me about 15 minutes for just the PC and LCD monitor, more that enough for me.

Well, that's strage.
Just tried again, keeping an eye on the task manager window, and when I'm exporting as H264 or H264 bluray on Premiere, the CPU usage goes between 70% and 80%, then the no break starts to beep.
A 600VA no break, just like yours. Maybe your UPS holds more watts than mine.
