S1000G overload alarm.

[Anonymous user]

The overload alarm will go off on my back up when I start up a game or anything graphic intensive.

All that is plugged into my back up are 2 monitors and my computer.  I am running 2 GTX 1080's and even at full load they do not pull over 600 watts.   The alarm only lasts about 30 seconds then stops and does not happen again until I start something up graphics wise..  It just started this less than a week ago..  Right now idle I am pulling 156 watts..

Any ideas on this and maybe a solution?

Thanks.

Hi,

What is the exact model number or the UPS? You will find that information on the back or bottom of the UPS.

The model on the bottom is BR100G

Hi Edward,

What model PC do you have? More specifically, what size/type power supply and what model graphics card do you have.

The Overload condition is most likely in response to an inrush current associated with the demands of your graphic card.

I have a 1100wat psu and dual GTX 1080's, it only started this a few days ago..  Has never done it before..

I can't explain why you may not have had issues in the past, other than that the Graphics cards and PSU may not have been operating at even half of their true potential.

Although the BR1000G produces a Quasi-Sine wave which is better suited for use with PFC or APFC power supplies than Step Approximated, it's limited 600 watt capacity is not sufficient to adequately support your configuration.

I would recommend using nothing less than a BX/BR1500G, which with it's 865 Watt capability is still undersized and may continue to experience issues if you were to add any additional peripherals.
