i7-13700K + 3080Ti with MSI MEG Ai1300P PSU (1300W)

Take a look at this APC BVX2200LI-IN, 1200w rated for 12.2k
and
Take a look at this APC Back-UPS BR1500G-IN UPS rated 865w for 14k


Suggest any other options within the budget of 10-15k.

My previous UPS had an issue. I've ordered some fuses/parts for it, but I don't know how long it will take or even if it will be repaired.

So I'm looking for a temporary (maybe permanent, God knows) solution. Any help is appreciated.

For a permanent solution, buy an inverter and run it in UPS mode. Yes, some inverters support UPS mode. But you'll have to deal with the invisible acid fumes from the battery.

Also, I used to use APC UPS during the mid/late 2000's and they used to run fine. But these days, consumer grade UPS are shit. So unless you wanna go with enterprise grade UPS, stay away from APC as they're just charging more for brand name.
 
My luminous zelio 1100 12v inverter couldn't handle corsair 550w psu properly.

It worked fine when taking over after light cut. But turning it on directly from inverter had problems. First power button press on inverter, it showed overload. Second press it worked fine. Maybe the surge current is high on higher end psu. Maybe battery was too old. Who knows.

Also check inverter changeover response time in ms. The lower the better.

7800x3d perhaps? and 80% powerlimit on 3080ti.

I was able to run 5950x + 3080ti on APC 1100, TV not connected to UPS. I just make sure cpu + gpu consume ~400-450watts in software. My target is 4k 60fps only though.

It says 900w and my PSU is 1300w. Will I run into any issues while gaming?
Btw, this UPS seems better for its price

Are you suggesting replacing the motherboard and CPU? :(

Are you utilising 1300w ? I would suggest you to use any of the online calculators to check.
There is a 2200VA model as well -

2200va seems the better choice.
Checked with a smart plug, the total power usage varies around 800-850w

Also, if you can share, what could be the backup time at full load in 1500va?

Got it, thanks.
Also, would it be a good idea to use this with a home inverter since I have frequent (daily once or twice), short power cuts in my area?
The inverter uses modified sine wave and that causes my PSU to trip while gaming [not in normal usage].
This won't cause any issue for the UPS/PSU?

Assuming 2x 12V 9Ah battery is installed in the UPS, you'll have a per cell current of 1500/(12x2x6) = 10.41A. So it would be approx 25 min.

My bad. I considered 9 Ah of the 2200VA unit instead of 7.5 Ah of the 1500VA one. Also the current draw is per battery not cell. So for a 450W load the VA rating will be 750, yielding a current of 750/24 = 31.25 A and a runtime of 5 min.

Also considering you have 2 power cuts a day and the battery is fully discharged each time, you'll be using 2 cycles a day with 100% drain (DoD). So battery might wear out over a short time span. The figure shows a 60% capacity after 200 cycles.

Well reviews are what they are. While I have not faced any issues, I admit I don't game. I do have a workstation connected which handles similar workloads. I am using the 1500 and 2 of their 600 VA models. I do have generator backup though so those are just for the switchover support.
I have had two of those Frontech ones, being praised, conk off in less than 15 months, so no to those. I will stick with Cyberpower or get an APC.
In the end, you will only need to do your due diligence and decide.

This is why using a 2kW or more inverter (with a decent switchover time) + 2*150/200Ah LA is the way to go, imo. Greater LA capacity => way lower depth of discharge => way more cycles/lifespan. Also, the SLA batteries you'll find inside a UPS are inferior to the flooded lead acids you get with an inverter setup because eventually the electrolyte dries up, whereas with the flooded ones, you can top them up indefinitely.

Another idea is to make your own LFP battery + BMS for the inverter and get a system that will last you for more than a decade like @rsaeon is doing, which wouldn't be a bad idea considering the frequency of power cuts you have and your energy demands but that is its own can of worms, even more expensive and I digress.

I would just sell your APC UPS for a good price and buy/save up for a higher capacity inverter + LA batteries. That is what you actually need. Maybe get a local inverter shop to do it so you can have them test the switchover time of a few inverters under the heavy transients of your gaming pc.

The only thing inferior about them is the smaller capacity since they are physically smaller.
  • Sealed Lead Acid battery aka AGM VRLA (Absorbent Glass Mat Valve Regulated Lead Acid) are sealed and require no maintenance.
  • The electrolyte in flooded batteries doesn't dry up due to evaporation, but electrolysis where water (H20) splits into Hydrogen and Oxygen gas and escape.
  • Since AGM VRLAs are sealed, the gases are trapped inside the battery and recombine back to form water, therby restoring the original electrolyte level.
  • Since they are sealed, there's no risk of leakage even if the battery is installed on its side, upside down etc.

Best option would be to keep the PC UPS and hook it up to a Home Inverter. This way you don't need to hunt for a HI with fast switchover UPS mode, which may consume more current.
 
If you're looking try out a pre-built lifepo4 pack or build one yourself, myinnovation.in currently has a flat 10% sale.

For bare 32700 cells, this brings the price down to Rs 185 for a 3C rated cell inclusive of taxes and shipping.

I purchased 120 of these from them during their previous sale last month for an upcoming project and they arrived within a couple of weeks. Packaging was decent and a few randomly chosen cells tested okay.

The founder/owner appears to be humble and hardworking, he posts behind-the-scenes shorts and videos on their YouTube channel. In one of them, while he's trying to show the legimacy of his enterprise because of the criticism they receive for not having a cash on delivery option, he inadvertently shows their total lifetime revenue — over 5 crores!
