Brownouts started to show in summer

[RentGPU]

It's summer now and in my country we have a bad electrical grid, so brownouts started to show from time to time , i want to protect my electronics i invested alot of money on it , so should i go with the voltage stablizer or UPS , i have a well separated mining machines 2 gpus each with power 600watt (good quality power) with over and under voltage protection , but i want to add another firewall in the power way ,so whats better for brownouts stablizers or ups?, i don't want to run my miners when power goes out , so stablizers will perform well?

A UPS is generally going to provide the most reliable power, but you're going to need a pretty substantial one for each system, and don't expect it to give you more than a minute or two of run time at full load.  If you expand beyond 2 GPU/machine, you'll need to look at datacenter-grade UPS systems.

A ups will be a big added cost , i am thinking that a ups is a stablizer with a battery so i don't need the backup power i just want to protect the machines when power goes and return aggressive voltage

Yes, UPS is additional cost but will temporarily address your problem regarding blackouts.
For long-term investment, you might think of solar panel system & now you can say that this system will give you the most reliable power.

really a UPS would be what you need. Not that big of an investment if you've equipment to protect!

Since the best PS's, Corsair, EVGA etc etc have a spec'ed input voltage range of 100 to 240 VAC wouldn't you be ok as long as you are operating on the higher side, say a nominal voltage of around 200VAC?

This is the advantage of a modern switching power supply as opposed to ones that use an input transformer.

i agree UPS would be the best bet not only because of a battery but because of a separated circuitry from outer grid. If you cant afford it, then as an alternative you try finding adjustable transformer that also has a "breakout" between your load and a grid, but i bet it would not cost less than a UPS. Also, you can use UPS without battery and buy "bad" UPS with bad battery for a fraction of a price and use it as high grade filter (without offline capability)
