sanctions are getting much of the things worse and worse, and I think, sooner or later, there will be a big problem with flying to Syria, or may even get banned !!

the bloody regime here wont let us live normally !!

What are we debating here? That a line interactive ups should power a pc without it shutting down, when everything (pc,monitor,ups, etc) is in specs?
I agree with you, how does this help OP?
Before these chinese knockoffs I kept using MGE(now APC) line interactive and it was a hit or miss on my gaming pc, but no problem with my office pc.
Right now I can run prime and keep switching on/off the power and nothing will happen.
OP has tried line interactive and wants a solution, so he either lives with it, or buys a bigger line interactive ups/maybe better psu and hopes everything is in specs and it stays on, or goes online.

OP lives in Syria, and sanction has made it very difficult to shop for a UPS. I'm just saying the problem is more likely the fact that it is not pure sine wave, rather than topology.

Shopping a different PSU is definitely another option, as some PSUs are more friendly to UPS.

I am not thinking AT ALL of getting a new PSU, this one is doing its job greatly, and I haven't had an issue with it so far, but it seems like an idea that I look for FPS UPS units to go with my PSU as i's FPS brand too ??

there are some of FPS UPS units here, but I should phone the store for their prices, because it is a different store from the one I posted earlier, and that shop doesn't post the prices on its website, claiming that this is due the non-stop changes happening to the US$ nowadays, and I think he is right in this...

but I really smell like they are so much expensive, if the prices were OK for me, I will post some of those UPSs here to discuss the matter with you guys..

and I hope you bear it with me, that I am really not that power-related issues expert.

If the store allows return, then I would just buy it and try it. If it doesn't work then return it.

I just thought of something, can the UPS be powered by another UPS unit ??

I have an old UPS ( 650 V/A if I am not mistaken) laying around, I will take for maintenance in the next few days, after this, can I use it to power my current UPS that is feeding up my PC ??

does this solve the problem if this is doable ?? so when I have a power outage, the first UPS will start peeping, but do you think the other one ( the Mercuray one I currently have that will be fed up by that old UPS) will peep also ?? will my PC restarts too if I am playing a game ?

Sorry about the long wait. Adding another UPS to the line isn't going to solve your problem. This is because ultimately your PSU gets its power from the Mercury UPS.

well, don't worry mate...

I know what you have said, but think of this please ! the Mercury UPS (that's powering my PC) will be powered by another UPS ( tell me if it's OK to power an 800 V/A by a 650 V/A one) so in this case, when I have a power outage, the Mercury one will not detect that power outage because it's already fed up by another UPS, right ? so here I can quit the game or what every source-intensive application that will be running then turn off the PC normally... is it going to work ??

I understand your concept. You can give it a try, but two things I have in mind,

* Your 650 VA UPS might not be enough to power the Mercury UPS. How many wattage can your 650 VA UPS provides, and how many wattage your PC pulls when gaming?
* I take it your 650 VA UPS is also a offline/line interactive UPS. So when your 650 VA UPS switches to the battery mode your 850 VA will also switch into battery mode, due to about 2 to 10 ms of zero volt from 650 VA switching.
