I understand that. From your post, it sounded like you were trying to apply efficiency incorrectly.

So I got another and have the same issue, the unit shuts off and it is showing only 80% load. No overload beeps or anything, just 4 beeps then reset.. 4 beeps isn't even in tech supports computer.

Its a VA1500 900w but this one has an LCD display showing load.

Do you have just the PC plugged into this? Anything else?

80% load seems unlikely. With everything overclocked and all under 100% load that would translate into your entire system(assuming nothing else is even plugged in) to using around 600-650W and ~720-ish from the wall.

600-650W for a 5820K and 2x 980 Ti's all overclocked seems low.

Try setting your PC stock and see what happens & also make sure nothing else us drawing power through the ups

3340x1440 monitor and PC only. Like I said its x2 980TI's and overclocking doesn't matter, it shuts off on stock clocks 70-80% load.

So what do guys with 3 or 4 way sli use? I changed outlets with the same results. 70-80% use then shuts off. So the usage meter is wrong because 900w and 1500va isn't cutting it.

I'm using the Cyberpower 1500 AVR (1000W) with no issues like that. I have maxed out the load at 810W while stressing. The Cyberpower brand UPS is, in my opinion, one of the cheapest brands out there. They have really poor cooling (but are quiet) and use simulated sine waves for AC replication. I use one only because it was on sale for a price I couldn't refuse. If I were a rich man I would get an APC brand. I would try a 1000W+ model and see if you still have an issue.

The only time I have seen a UPS act like what you are describing is when it was overloaded, you can simulate that with a heat gun or space heater to confirm as they tend to pull a lot of power. That being said, there could also be a wiring fault in your house causing it to act wacky. I have seen very dirty power cause UPS' to act unusually. I'm hoping Its not an issue with your PCs power supply, perhaps when its cooling fan comes on something happens to the load.

Have you used the software from their website to confirm you are only using 80% load? It might also give you an error before it fails on your pc, but im not sure about that. I hope you can get the problem sorted out before anything gets damaged. Let us know what progress you make.

Ended up being I needed a pure sine wave and not simulated sine wave UPS. Simple as that. Pulling around 95% load benching and not a problem yet. It's only a 1500va 865w APC. 800w load, 300 idle. It should work fine just for my pc and monitor.

Glad to hear you got it figured out. thumb.gif It's definitely worth a few extra bucks for a decent UPS.
