300w UPS enough?

Hi all.

I got a 300w UPS and it seems to run fine on my rig.
Q9550, 8 gigs RAM, AMD 4870, 5 hard drives, 850w PSU, etc.

90% of the time, I'm just reading news, MS Office, etc. and I think I'm still within the PSU limit.

My system can go way above 300w under full CPU/PU load.

So, is this safe enough? I don't expect the small battery to last more than a few mins during a power outage and this is OK for me. But will I do any serious damage if I run my rig with a high load - with and without a power outage?

That will work just fine. It's only there so you can safely shut down the system during a power outage. I applaud you for actually using an UPS, most just use a power strip.

Ups = Va not watt
and PSU = Watt, you can try turn off power AC and how much second your PSU will shutdown ? If more than @minute you have time to shut down with safely.

The UPS is actually clearly labled as 300w and 500VA.
It seems as simple as just using what battery juice I have.
Yes, there is plenty of time for me to shut down my rig normally.
I'll keep using the small UPS that's working well for me :)
