I've got a sweex 650VA and the following hardware:
- i7 3770k
- 32 GB Ram
- z77 Extreme 4
- MSI nVidia GTX 980
- 2 HDD 5.25
- 3 SSD
- 1 DVD RW
All supported by a 700 W power unit.
When I use particularly intensive games such as Metro Last Light Redux, after ~20 mins of gaming (cpu is used ~370% and videocard ~100%) the sweex ups starts beeping twice every 1 second (looking at the manual seems to indicate "overload").
What can I do to prevent/fix this problem?
How is this possible? An estimate of my system should be ~550W under extreme usage. Should I buy a new better ups? Should I set the spindle disks to shutdown on non usage? What do you think about the 700W power unit, is that enough?
Once I stopped the game, after ~1 min the beeping stopped.
I'm running Ubuntu 14.04 x64.
Is your monitor(s) and printer connected to the UPS as well? – LawrenceC – 2014-12-26T12:56:13.213
No, my two displays are not connected to the ups, neither printer nor anything else. – Emanuele – 2014-12-26T12:56:59.440
What is the brand and model of the power supply? Different units have different efficiencies, and the very cheapest ones might not have active power factor correction. – ntoskrnl – 2014-12-26T19:22:54.033
