UPS doesnt power PC

[overclock98]

My computer had burnt its power supply and graphics last earlier this year so I got a new corsair 850 watt power supply now when power cuts happen sometimes it doesnt restart when power goes off but sometimes it goes off it used ot happen with old power supply as well which got burnt with the graphics card I have tried 2 NEW UPS and have tried my old UPS in my other computers they seem to be working well with those but not in my computer. Sometimes it goes off when power cuts happen but when I do it manually with turning off teh switch it doesnt go and sometimes it goes off I have tried switching off main switch for electricity it didnt happen then but due to this my graphics card and power supply have died. what should i try doing? the guy who i bought the ups from said theres something wrong with power supply

The function of the UPS is to allow you sufficient time to save your work and properly shut down your system. It's not supposed to allow you to keep working/playing indefinitely. Additionally, it's only rated to provide so much power. If your computer's current power requirements exceed that of the UPS, your system will shut down immediately.

yes I know that when power cut happens the ups takes time to provide that power in which the pc shuts down and restarts which lead to old graphics card and power supply being burnt, i tried turning off main power point to whole house it was working then but when there was a power cut the power got cut and the pc restarted

Does your power supply have Active PFC? Most basic UPS units don't accommodate power supply models with this feature. Some of these combos won't play nice together. UPS' that produce Pure-Sine output or have technology to work with Active PFC will be listed on features,

Your model has active PFC. What UPS do you have?

this is the new one i tried with that i am using right now

Seems like a basic unit with limited capabilities. What are the rest of your system specs? This model can only deliver a max of 360w. Generally, you don't want a load of much more than half of that in regular use.

my system specs are
CPU - I7 2600k
motherboard is intel dp67bg
16gb corsair vengence ddr3 ram
1 250gb samsung 750 evo ssd
1 120gb ocz agility 3 ssd
seagate barrcuda 4tb HDD
seagate 500gb hdd
graphics card is gtx 560 ti currently will be upgrading to gtx 1070 once i know why my ups doesnt power my pc during powercuts and when i manually turn off all lights it does
power supply is the one mentioned above
I use benq GL2450 with the UPS as well

I'd suggest you look at a more robust UPS. You're pushing it as it is if system is under load/gaming. I could see why the system shuts off during a power outage based on TDP ratings of components. The difficulty turning system back on is likely the safety mechanism in the power supply itself. If the UPS can't supply the power needed or voltage isn't clean, the protection in the PSU is likely doing its job.

I just tried turning off main power switch of UPS it worked, it power didnt get interrupted. what I mean is sometimes during powercuts the ups power gets cut and my pc restarts due it doesnt supply uninterrupted power so i can have tiem to shut down.
sometimes its power doesnt get interrupted sometimes it does, the guy who i bought ups from says my psu is faulty

 

[1LiquidPC]

OK. How long of a timeframe does this happen when the issue occurs? I'd still blame the UPS as it's considerably cheaper than your PSU itself, which should be good quality. Use same brand myself, and yours isn't entry level either. A decent UPS for using in a gaming setup can easily cost $100 or much higher depending on needs. Is there any way to return the unit for something stonger? Could be a faulty battery as well.

well when a power cut takes place ups doesnt provide instant power due to which my computer restarts without me able to giving it shut down command which leads to burnt graphics card and power supply a few months ago which happened in same fashion. now when i turn off power from main switch it works sometimes and other times it doesnt work, during actual power cut it doesnt instantly power it and that leads computer to restart. the guy who sold me ups said i tried ur old ups in other computers and it works with all units he also \tried new unit and that also works.

Still think its the UPS. I'm using several on a few different computers. When power goes out, other than UPS beeping from running on battery, everything plugged into it runs normal. No power cuts or restarts of any kind. If a UPS is correctly matched for power requirements, output needs in VA and wattage, and quality for your PC, you should at least have several minutes of uninterrupted PC usage to properly shutdown before shutting off. There should not be restarts from the switch to battery. I would look for a model that says it supports active pfc if it were my situation. Otherwise, there isn't much you can do with current setup.

Can you recommend me a ups according to these specs

my system specs are
CPU - I7 2600k
motherboard is intel dp67bg

1 120gb ocz agility 3 ssd

Which is exactly what a UPS is suppose to prevent, power loss. So I'm in agreement with everyone else, your UPS isn't doing its job. You shouldn't even notice when your UPS kicks in.

I use an APC 1500va, which cost me around $150-200 at the time I think, I forget the exact model. I've used CyberPower in the past, but have had better success with APC.

In regards to what 1LiquidPC said about active PFC, that's something I wasn't aware of and it's got me wondering about my own UPS now. Though the price I paid for my smart ups just a few years ago, I'd imagine it's all good.

 

[1LiquidPC]

I also recommend the same brands as mentioned above by phaelax. I use exclusively APC and 2 Cyberpower units on more "light use" PCs. My APC is SMT1500 Smart-UPS with Pure-Sine output. My other models are 1000VA and 1350VA model of Cyberpowers. The 1350 is CP1350PFCLCD. Some quick searches can provide ActivePFC with regards to UPS. Worst case it can cause damage when swtiching to battery, but more likely it causes reboots.

 

[overclock98]

So, I have ordered the RTX 2060 from zotac and I am thinking of buying a UPS to safeguard my pc from sudden power failure. I have narrowed my search down to this UPS and wanted to know how it is in terms of specs. any help is greatly appreciated.

this is the ups

https://zebronics.com/products/pc-ups/zeb-u1200

its hard for me to find APC or cyberpower here

 

[1LiquidPC]

What brands are available in your area? Budget as well. A quick search for the brand doesn't show the best results in reviews, but they are budget oriented models.

 

[overclock98]

apparently, apc is available here but cyberpower isn't, i wanted to know i need a pure sine wave model right? is there a model that i can have in my room and its battery outside my room because i read when u turn it on it smells like battery acid and i dont want that in my room.

 

[phaelax]

Technically, you could do that if you remove the battery and run very long wires to it. But if the smell of acid is an issue with that model UPS, I wouldn't buy it.

 

[1LiquidPC]

A UPS shouldn't smell like anything unless it's faulty or a leaky battery, which would be dangerous. Been using mine for years and only a few feet away on desk beside PC, and never noticed any kind of a smell. Were you considering a specific APC model? Their pure-sine models are great, but very expensive for home users. This is why I had mentioned Cyberpower as well, as they have much more affordable alternatives. Also, models with "simulated sine", such as the Cyberpowers seem to work fine in my experience.

 

[overclock98]

I talked to an Apc reseller, and he told me about the ups he has available. I asked him about the apc internal battery model That's brg1500. He told me I need around 1500 va. I told him about my concern of battery smell and asked him if the power supply he has are pure sine wave or not. I asked him about a model that offers 2000 va and has external batteries which will be placed around 2-3 metres away from my pc. He Also told me that the ups is not pure sine wave but its quasi sine wave, now my concern lies whether my power supply will support a quasi sine wave ups and whether its a good choice over pure sine wave That's also a smart ups

I think the model he recommend me is this

https://www.apc.com/shop/in/en/products/APC-Back-UPS-2000VA-Without-Battery-with-Selectable-Charger-and-Flooded-SMF-Compatible-230V-India/P-BX2000UXI

 

[1LiquidPC]

It should work being APC. Still wouldn't be concerned about battery smell though. APC has always been my top choice, but recommend Cyberpower as well, as they are what have worked fine for me.

 

[phaelax]

I thought I was using APC these days, lol I just looked at mine and it's a cyberpower 1500pfclcd. Pretty durable, considering how heavy it is and I dropped it off a shelf from 6ft and it still works fine.
