Question UPS battery backup starts beeping and PC shuts off

[brandonmacleod21]

I recently upgraded my memory from 16gb to 48gb and it seems to work fine but whenever I play a graphically demanding game, I hear a single continuous beep from my UPS. Sometimes, my PC even shuts down. It seems to only happen whenever I play any graphically depanding games. My UPS is 650VA and my PC only shuts down when it's connected to it. Here's my PC specs.

Nvidia GeForce RTX 3070 Ti
AMD Ryzen 5 2600 Six-Core Processor 3.40 GHz
48gb of ram
1440p monitor
1000 watt power supply

I'm just wondering if there's a way to fix this or if I need a new UPS.

Which exact PSU is that please?
Also which exact UPS do you have?

It sounds like the UPS is not large enough for your system and is likely shutting down due to too much current draw.

My exact PSU is an ATG1000 80 plus gold certified power supply. My exact UPS is a CyberPower ST625U standby UPS system.
