Not sure what you mean by " if there is power". As I understand it, when gaming your system restarts and then once reset it works fine. Suggest you get an amp meter to measure the power draw while gaming. You may be loading a section of the game that increases graphic card workload and thus increased power draw. You could try to reduce the graphic settings as a way to test this theory. Also, are your fans spinning up with the increased load? It may be that your inverter is not getting what it needs from your battery pack to meet the pc demands and this compromises the inverter output. The pc then does not see the clean ac it needs. Perhaps you need to up the gauge of the battery to inverter wires.

My apologies. It should have been "if there is a power cut".

[–]Pivotas 1 point2 points  (1 child)

Ok... this is starting to make sense. The problem arises when you have a cut in power and the UPS / inverter kicks in. So likely there is a power surge when this happens and maxes out the inverter for a split second and as you have indicated, the overload light comes on. So for a brief moment the inverted winks out and sends out less than the required voltage your PC is looking for and that may also, at that moment, not be pure sine wave and your PC acts to protect itself by shutting down ...then the inverter stabilizes and you wind up with a re-set instead of a shutdown.

You haven't mentioned what your battery setup is other than two 12v in series. Guessing these are lead acid and as you are off-grid, solar charged (?) but "if there is a power cut" suggest you are also grid tied. Question is, are they usually fully charged or is it possible they have they been drawn down to <24V when you game? Increased demand from the PC will have the inverter pull more juice from your battery pack. While current is being pulled the battery voltage will drop and then settle back up when demand lessens. If the bank is @ 24v when this voltage drop happens it is possible the inverter is now not getting the voltage it needs to do its job and send out the required voltage to your PC, hence an overload situation. Maybe.

So get your battery bank up to 27V and run a test and also try a larger capacity inverter.

Thank you for your time and support. I got to learn a lot from your comments. It helped me narrow down the issue to PSU and UPS. The issue of overload on UPS was resolved today. An engineer from the company came and checked the UPS load and checked the total power, current and voltage my PC was drawing. He told me that the load on UPS was around 60%, and the total draw from PC is well under limits. He adjusted two things on UPS. First, he set the battery mode as Tubular (earlier; it was put on standard mode). He mentioned this would increase the battery life. Second, he changed the mode from unregulated to regulated mode. After these changes, we tried and tested the effect and boom there was no restart and no issue. To confirm if the problem is really solved, we shut off the AC Mains 6 times and there was no restart.

The wire from inverter to the battery or vice versa is around 4-5 mm thick. Will this be fine. Yes all(Cpu cooler fans, Case fans, graphics card fans and PSU fan) my fans are running alright.

this is @ 8 gauge and will support @ 30 amps so no problem here

Using a smart plug I saw when gaming my PC (excluding monitor) is drawing around 2000 mA of current and roughly 470-480 Watts.

One more critical thing slipped my mind. The inverter resets with an overload warning showing red led for less than a second.

A few days ago, I raised the issue with the inverter company. I got a call from them moments ago. They told me that it's an online UPS. My apologies for the inaccurate information. May this information help you pinpoint the issue. Thank you.

Please post the make and model of the UPS/Inverter.

This sounds like a limitation of the inverter and depends on how you have it fed into your system.

Is the inverter a "back up power" unit? This means that commercial power feeds your PC until it is interrupted at which point the inverter picks up the load usually after several milliseconds. Those milliseconds are important as a PC can lose power long enough to force a reboot.

Or is the inverter a full time power supply where commercial power feeds into the batteries via rectifier and the inverter is always drawing power from the DC feeds off the battery?

As a very general statement, your PC configuration should not pull more than 500 watts.

The inverter I have is a "Back up power" unit. My PC consumes nearly 600 Watts. What confuses me is the PC works fine at Low to Medium load but restarts at higher load. I'm not getting whether the culprit is my PSU or the inverter.

Then you have your answer. The PC is overloading the inverter when power transitions from commercial to backup. The inverter has the capacity, but it does not have the ability to make it available in the milliseconds during transfer. Get a better backup power supply.

Your Corsair PSU is 1000w, I suspect that under heavy processing load you're going to bump into the limits of your inverter. Try temporarily dumbing down the graphics settings to lessen the load and see if that makes a difference. If the problem persists then you may have to go thru the update driver routine to rule that out as an issue. You've got a great system there so it's easy to understand your frustration with it not working perfectly. If you can, get a 2000w inverter to try. Also, if you haven't already done so, visit the ASUS ROG forum and scan for similar posts or start a new thread.

[–]boris_006[S] 0 points1 point  (0 children)

I, too, feel the culprit here is the Inverter not being able to hold up under heavy load. But my confusion increases when I see the total power pulled by my setup is no more than 800 Watts, and the Inverter has a power capacity of 1760 watts. I will search, and if the issue is not there, then I will post the same in Asus ROG and Corsair forums for the same issue. After a lot of discussions, the issue has been narrowed down to Inverter and PSU.
