Hi Guys,

Built my new PC with a 850w PSU as suggested by you guys and while the PSU is adequate, during surges the power goes above 600-630 watts and I get an annoying alarm from my current APC UPS which is rated for 1000VA/600W.

Suggestions for a bigger UPS? Say 1000 watts?

I have the BR1000G and that's what is causing issues.

Then what Microtek or Artis UPSs. Or Cyberpower?
Microtek is best for Inverters I think.

If Artis is reputable I found a Artis 1200W for under 10K but unsure of the brand

If Artis seems OK, I'll save the 5K.
 
APC might be reputable, but a quick search will show their reputation is not that great in India. Cyberpower is also a well known brand but again, I have no personal experience.

Line interactive UPS is not a very complex hardware though, so if you really need support and the brand is not helpful, you should be able to get some paid service done in the long run.

In my list, APC ranks lowest regarding reliability and maintenance.

Again, it's my opinion. And, it's not a popular opinion.

Artis, like all non-APC brands out there, are just rebranded generic Alibaba UPS.

Presently, I'm using an Artis 600VA as my main UPS. I have an APC 1100VA UPS with fresh batteries sitting idle, kept as a backup.

I would highly recommend you to go for a Pure Sinewave Inverter than a UPS. You would be spending 15k+ for a reputable 2200VA UPS, which would give you less than 10mins of backup. Two years down the line, the UPS wouldn't even be able to provide a backup of 5mins. Three years down the line, you need to change batteries to even use it.

Very true. Better to use a high rated pure sinewave inverter (or upgrade if you already have one but it's not able to keep up with the demand). Cost will be less (or slightly higher with battery) and/but inverter will last you a decade at least. Example of a good beefy one (not sure this is affiliated link or not, I choose a trusted seller from the list as others were bad).
But I will understand if you are not wanting to buy an inverter due to space/budget issues.

Change Over time of sinewave inverter is bad.
See the waveform on full load on oscilloscope.

Personally used Apc and Microtek.
Microtek has better longevity and reliability.
Apc died on me all of a sudden.

As long as change over time is less than 16ms PC will run fine. ATX 3.0 PSUs are required to have hold up time of at least 16ms and since that's a minimum requirement and not fixed number some PSUs are capable of much better hold up time, I have seen 30ms from a PSU (rare exception though). If inverter is set in UPS mode (which that inverter I linked is capable of) their switch over time is quite fast. That Luminous Optimus 2300 has <20ms of change over time which is bad to be honest but considering OP's PSU won't be running at 100% capacity (which is what their hold up time is tested at) the actual hold up time will be better.
Also we don't exactly know how much watts his PC consumes at peak load, he hasn't shared his PC specs. Which if you ask me should have been the first thing + his budget.

I have done that you will face frequent reboots.
Luminous and microtek pure sinewave inverters that I have used both have softstart up.
Tried that with both active pfc smps and passive pfc smps.

Well I wouldn't deny what you said but I'm using a 600W PSU I bought 10 years ago + a new luminous eco volt neo 1550 inverter on UPS mode and both together are able to keep my system running during power cuts if total system power consumption is below 300W. I'm saying 300W because I have tested my GPU running at 100% on furmark consuming 270W which is fine but as soon as I put more load like running CPU stress test it doesn't hold. Right now I have set power limit on my 3070 at 70% to combat this issue. BTW this is with 2-3 fans and 4-5 lights running in other rooms in the house. Now If I'm to guess I will blame the old PSU for having a degraded hold up time since it's so old now and pretty much at the end of its life. I'm not sure how well this holds for PCs with 600W+ power consumption which is why i'm interested in finding out what specs @deepakvrao 's PC has and that it's not his UPS that's shitting the bed here due to having degraded performance like my PC's old PSU.

Also a bigger than needed PSU will help with hold up time because it will have higher amount of capacitors to stay within it's ATX's standards hold up time.
May I know what you had when you faced those frequent reboots ?

Specs

9800x3d
7900xtx
2tb nvme
850w psu
64gb ddr 5 6000mhz ram

My current apc ups as well as a Smartplug show max draw of 630 Watts with cpu 50 percent and gpu 100 percent.

Gpu draws 470 to 500, cpu upto 70 to 80 or so and the other parts make up the rest.

I have just installed a luminous 3.5kva inverter for my entire house. It has ability to be put in ups mode.

So, then I can do away with UPSs completely?

I'll test it when I get home next week.

Could you please tell the exact model of this luminous inverter, and what is it's waveform type and how much is its switchover time?

This would be very good option, if we could make sure that the PC would not shutdown during the switchover time.

As someone has already mentioned, even if the inverter is labeled as pure sinewave, still the PC might shutdown, which could cause data loss and other issues.

Buying a PSU with bigger capacity might be helpful in this scenario for sure. I am not sure if this has any minus points, other then higher initial buying cost of bigger PSU.













I asked about the PC switch off issue on Perplexity, here is the response -

To ensure your desktop PC remains powered during electricity cuts, here are the critical factors to consider when selecting an inverter:

1. Switchover Time​

  • Requirement: ≤ 10 milliseconds (ms).
    • PCs require a transfer time of <12 ms to avoid shutdowns. For optimal performance, aim for inverters with ≤5 ms switchover time in UPS mode212.
    • Example: If the inverter’s transfer time is 8–10 ms (common in UPS mode), your PC’s power supply unit (PSU) must have a hold-up time ≥17 ms to bridge the gap28.

2. Waveform Type​

  • Pure Sine Wave (PSW):
    • Mandatory for sensitive electronics. Mimics grid power, ensuring compatibility with modern PSUs, monitors, and peripherals.
    • Avoids issues: Overheating, electrical noise, data corruption, and hardware damage4569.
  • Modified Sine Wave (Trapezoidal/MSW):
    • Not recommended. Can cause compatibility issues with active PFC (Power Factor Correction) PSUs, monitors, or laser printers510.
    • Example: The Microtek 1550-vTURBO uses a trapezoidal waveform in UPS mode, which risks damaging sensitive electronics over time4.

3. VA Rating Calculation​

  1. Calculate Total Load:
    • Add the wattage of your PC, monitor, peripherals, and other connected devices.
    • Example: 500W (PC) + 50W (monitor) = 550W total.
  2. Convert to VA:
    • Divide by the power factor (typically 0.6–0.8 for PCs).
    • Example: 550W0.7≈786VA\frac{550W}{0.7} ≈ 786VA0.7550W≈786VA.
  3. Select Inverter:
    • Choose an inverter with ≥ 1.2x your calculated VA (e.g., 950VA for 786VA) to handle peak loads17.

4. Inverter Modes​

  • UPS Mode:
    • Enables faster switchover (≤10 ms) and narrower voltage input range (e.g., 180–260V)8.
    • Avoid inverters that only offer ECO Mode, which typically has slower transfer times (10–20 ms)3.
  • Double Conversion (Online UPS):
    • Best for zero transfer time but costly. Ideal for critical setups12.

5. Battery Capacity​

  • Backup Time: Depends on battery size (Ah) and load.
    • Example: A 150Ah battery with a 500W load provides ~2–3 hours of backup3.
    • Use tubular or lithium batteries for longevity.

6. Additional Considerations​

  • PSU Compatibility: Ensure your PC’s PSU supports active PFC and has a hold-up time ≥17 ms2.
  • Grounding: Proper earthing is critical to prevent

This is the one I have and it says switchover is <10ms and the manual says 'pure sinewave inverter'. This is what my PSU it says about hold up time:
