UPS shuts down immediately during power failure while gaming
It includes a sealed lead acid battery, operates at 24V, and has a 9Ah capacity.
You can obtain a tool that displays the real power consumption when the UPS fails to show it. Killawatt is a well-known brand, though more affordable generic alternatives are available. After determining your wattage draw, you can work out the theoretical maximum capacity. At 24 volts, 216 watts would last one hour; for 30 minutes it could be around 432 watts. This figure assumes no losses in the direct conversion from DC to AC and is an ideal estimate. In practice, batteries often degrade faster when drawn quickly, and actual runtime may be shorter. It’s also possible your batteries are faulty, and measuring battery capacity accurately is difficult. The device likely maintains voltage correctly but doesn’t provide sufficient duration.
Also keep in mind that the UPS is assisting the computer and at least one monitor. The end result is that the UPS will offer even less time. This is especially true if other devices are connected to the battery side of the UPS. In summary, the goal is for the UPS to supply sufficient power and duration so the user can shut down the build and related components smoothly when power fails, preventing possible file corruption from an unexpected outage. The UPS isn't meant for gaming purposes, which is probably irrelevant during power disruptions—such as internet, modem, or router issues too.
I checked the readings with a Killawatt device during stress tests and gaming. The computer and monitor use around 520W under CPU and GPU load, and a bit less while playing games. The UPS has a capacity of 2200VA at 1200W, which should offer at least five minutes of backup during a power outage.
My concerns are:
1. Does this value include any sudden power spikes from the GPU (3080Ti)?
2. Should I replace the battery or upgrade to a higher-quality UPS like one from CyberPower?
I think the batteries might be faulty. It would be cheaper to try fixing them than to purchase a new UPS.
Many people roll their eyes when you mention cyberpower and quality, but it seems most have few problems with these products. APC is recognized for commercial UPS systems, though it's unclear how its consumer-market performance stacks up.
The UPS itself probably has a defect, but run-time problems usually stem from battery issues. Power spikes are more about the rating—specifically the 1200 rating. If you overload the UPS, most will alert you or shut down before causing damage. I doubt this would be a major concern for you, as your power supply is only 1000 watts and would likely shut down first.
I opened the UPS to examine the battery voltages and other parameters. This unit has two 12V (9Ah) lead-acid batteries connected in series, giving a combined voltage of 24V. Here’s the product information for the batteries: https://www.leoch.com/pdf/reserve-power/...12-9.0.pdf The voltage measured across both batteries when disconnected from the circuit is 25.1V. Each battery shows a voltage of 12.5V and 12.6V respectively. These readings suggest the batteries are functioning normally, so it’s unlikely they are the source of the problem. Could there be another issue with the UPS?
You can't rely on no-load voltage for any conclusions. They lack failed cells, yet their capacity might still be reduced. Consider swapping the batteries, as recommended by several individuals, or replacing the UPS. Your decision is up to you.
