I have a pretty power hungry rig, enough that I threw an 850w PSU in there. I've played around with a few wattage estimation/calculator sites and they've all suggested I would need at least 650-750w PSU in the first place, so my usage is definitely "up there."
To make a long story short, the UPS I have now simply isn't cutting it. With recent power outages, it's getting a surge and just dying immediately, and I can only assume it's overloaded (and I believe the light flashes "overload" when it does happen).
The current UPS I use is an APC XS 900 (900VA, 540W), so I can put two and two together to figure that it's a problem, but here's the question:
Seeing as the max wattage my PSU would be using is 850w, and considering the power it uses is never actually going to be that high, can I get away with APC's 1500VA version (1500VA, 865w)?
It seems to be the only relatively affordable UPS for a wattage above my PSU. I don't intend to put more load on the UPS, as I already have another strictly for the monitor and other electronics.
I appreciate any advice.
