I have been looking at a basic UPS for my PC. I have two questions:
**Why are the joule ratings on UPS back-ups so low? Most are around 400 joules and my current APC SurgeArrest is 2050 joules of protection.
**I have a 850w power supply in my rig. Does it matter what the VA rating is on the UPS?
I am looking for the power conditioning benefits of the UPS and not the battery back-up.
