Unfortunately where I live I do not have 24/7 electricity.
My new PC rig which is considered to be a high-end(gaming) system is connected to a brand new APS/UPS that have these specs:
DC-AC Inverter-Pure Sine wave
97% peak efficiency with power factor correction.
According to the company's technical support, they say it can provide stable 800 watt on 12V and even non-stable 1000 watt.
Of course I have a brand new Car battery (more-like truck battery) "N200 12v 200ah" connected to the inverter.
And I'm using a tier 1 PSU considered-among-enthuasiats that is Corsair AX860i — 860 Watt 80 PLUS® Platinum Certified Fully-Modular PSU with over current and undercurrent protection.
While I'm gaming, my computer restarts when a main power cut occurs, the UPS does take over but while it does the computer restarts.
Though, if I'm not gaming(low power consumption) it doesn't restart. And the UPS would take over without any interruption.
Taking into consideration that my GPU is MSI 980 gtx GAMING 4g.
I calculated my RIG power consumption online and under load it doesn't exceed 550 watt.
The only "non-high-quality" parts in this case I would think of, is the surge protector (or surge suppressor) that connects everything to everything! And there are two of them, one for UPS < main power and the other for UPS output < RIG.
What may be causing the restart when power cuts off while gaming? And is it going to shorten the life-span of my components or possibly cause damage? Also would you think it boils down to large switchover time?
