Pc doing random stuff when UPS changes power source..HELP!!!

[Goliath_1911]

So in my country the electricity is not stable, it sometimes goes from 220 v to 210 or 205 , and my Ups changes its source , or turns on its active pfc( i think that is what it`s called, something that like simulates a ac current idk, correct me if am wrong, u know the sound it makes like TICK then after a while TOCK) so 1st i thought it was the power supply , it was 10 years old... i changed it , same result, got a new and higher capacity (wattage ) ups. problem came back like before after  2 weeks.

So what happens is the screen flickers, sometimes the calculator in windows opens, sometimes the pc just goes to shutting down, sometimes steam music plays...

btw the screen is on a separate power source( home APS) same issue

when on the pc ups same issue still

specs i3 ,3k series (its old)

msi 1050 ti

ssd 250gb 

1 tb hdd

powersupply 650 watts

any idea what might be the problem??

The UPS doesn't "turn on active PFC" silly. 

 

It's the buck and boost of the AVR.

 

What UPS and what PSU.  Simply "650 watts" doesn't tell us anything.

late reply i know

the psu is http://www.aerocoolaustralia.com.au/de/psu/value-series/vx-650w this one, the only one i found at the time, for some reasons stores i looked at only had these types

UPS is Best one ups ( yup that`s the name) 1500va , it should handle if am right the pc

Ok.  That PSU is absolute crap.  You probably could not do worse.  It's about as stable as an epileptic quadriplegic with parkinson's disease riding a unicycle with a square wheel.

 

Ditch it.

Yeah, at the time i got it i couldn`t find any other brand, searched several stores , nothing.

i might hang on to it a while , am already planning on a new rig , this one got very old ( about or more than 7 years) 

any psu u can recommend for the new rig?

it`s gonna be a msi z370 tomahwack, i5 8500 , maybe gonna stick to my current gpu( 1050 ti) , depends , i may get a 1070 or wait for the new gen

 i found these tho , didnt get one since i didnt need that 850 w

by bad did u mean the brand or type? 

cause most of them had these aerocool brands 

Edit : i can order a psu from online sites , but they have to be shipped to my country , and our customs are bastards, for example if i order a 90$ item , when i receive i will have to pay like 30 or 40 $ customs extra ( that`s with out shipping fees ) 

for example i ended up paying 200$ for the jaybird x3 earphones which the initial price was 115 $ ( were on sale, shipping cost me somewhere between 20 or 30 $)

What country are you in where they don't sell computer parts?  That's really odd to me.

 

I can't say an entire brand is bad.  But Aerocool has done some really bad things.  Not just made bad products, but have done some deceptive things.  For example:  They have one series called "Integrator".  Kit Guru reviewed a unit.  I bought the unit.  The unit I got at the store was internally completely different than what Kit Guru reviewed.

 

It's probably just best to stick with a brand that in general has a good reputation, and then not buy a shit model because your mains power is so shiitty that you're going to continue to have problems if you use a shitty PSU.

 

Which brings me to the Thermaltake unit you linked.  That's from a reputable company, but is a shitty PSU.  It's the cheapest PSU from that company and while it might work well if you had stable mains, you're likely to have the same problems with it than what you're having with the Aerocool.

 

I'm not going to get into the deep technical of it, but the PSUs you are choosing have two "fatal flaws" in your situation.  They don't support lower input voltages (<200V) so they die if the mains drop below that voltage, and they don't have a hold up time as long as one cycle or power, or as long as it takes for the AVR in your UPS to buck or boost.  

 

If you have bad mains, you don't use a shitty PSU.  That's like getting bad gas for your car and then thinking adding water to the tank is somehow going to fix it.  It doesn't work that way.

Hmmm i see

the thing is pc gaming in my country was not that well known , most of them are console users(playstation actually , very few play on xbox, i am one of the xbox guys , rarely find another guy who has a xbone here lol) , they are not the typical gamers , most just play fifa or gta 5 or COD, until recently a sudden increase of high tech cyber cafes pc gaming started to grow here ,been a pc gamer for all my life, but the lack of high amount of demand on pc gaming stuff makes it hard and expensive to find all the decent stuff like a proper psu

so i think i should look for Corsair , cougar , thermaltake PSU`s with something like a gold psu and more than 80% efficiency , 

well until i get all the parts i need to start my build i think i would find by then a good one

i would be very grateful if u can tell me what to look for in PSUs , i know like alot of stuff on building pcs but nothing on psu

Thanks for your help and time  

P.S. the country is Lebanon , shitty government lol

It doesn't even need to be Gold efficiency.  If it has 80 PLUS (regular, not the 230V Internal), then you know it will support a full range of input voltages.

 

As for hold up time:  Just because something is Gold or Platinum or whatever doesn't mean it has the correct (correct as-in meets Intel's spec of 16ms) hold up time.

 

But if it doesn't have 16ms hold up time, but it does support full range input voltage, you should still be ok.  Because as the voltage drops, the PSU will continue to work until the AVR kicks in.  On a full range PSU, the voltage can drop all the way to 100V and it should still operate normally without relying on the charge of the bulk cap to keep things going.
