UPS shuts down immediately during power failure while gaming
Hi All,
Facing an issue with the UPS not being able to provide power backup on mains failure during gaming sessions. While gaming, as soon as the power fails, the UPS shuts down almost immediately and emits a constant beep (which indicates Online Overload Fault according to the UPS manual),
On the other hand if the system is idle during a power failure, the UPS signals low battery warning almost immediately.
This is a 2200VA APC UPS which should be able to handle up to 1200W according to the specifications.
I don't believe that the system should reach that kind of power even under load.
However, I am not sure if the GPU transient power spikes are causing any issues here, or if there is any other issue.
I had bought this UPS about 8 months ago, and just need it to power the PC long enough to be able to safely shutdown.
Here's my configuration:
CPU: Ryzen 5 5600x
Ram: 32 GB DDR4
Motherboard: MSI B450M Pro-Vdh Max
GPU: Galax RTX 3080 Ti 12GB
PSU: Corsair RM1000e 1000W
UPS: APC Easy UPS 2200VA Line Interactive (BVX2200LI-IN)
Any help will be much appreciated.
Examining this page shows the specifications and usage details. At 1200W, it provides 22 seconds of backup. The UPS is likely outdated, as batteries typically last 3 to 5 years under normal conditions. If you experience frequent power interruptions, the battery life may be insufficient. Given the quick drain during light loads, a replacement is probably necessary.
During gaming your device is drawing close to 40Amps from a battery close to a 4-5C load. Because of its compact size and likely poor maintenance, it probably has degraded significantly and hasn't received proper charging, which is typical for cheaper electronics. The voltage dropped below the inverter's cutoff point instantly. You'll need a much larger SLA with accurate frequent charging using suitable voltages and longer high-voltage periods. I purchased an expensive marine-grade charger from professionals that even fails to meet these requirements.
Even when operating at maximum capacity, the highest load power should remain under 1000W for the setup, indicating roughly a minute of backup time. The UPS is relatively new, purchased around eight months ago. I began noticing this problem only recently.
It looks like pulling 40 amps makes sense.
Calculating it another way: 40 times 12 volts equals 480 watts.
Or, using a battery feeding inverter at 40 amps, it would be 40 times 12 volts, also giving 480 watts.
If the backup batteries are in a 24-volt package, 20 amps times 24 volts also results in 480 watts.
This is the power the inverter draws when you lose electricity and the battery has to support your computer.
