Question My PC restarts when there is a Power Outage even on an Inverter while Gaming

[Darkr3nder]

As the title states, my PC restarts as soon as there's a power outage while playing Gaming. It doesn't happen if the PC is idle. Here are the things I have:

AMD Ryzen 5600
MSI MPG A650GF PSU
MSI RX6700 XT 12GB Graphics Card

Inverter: Luminous 1500VA inverter (Switched to UPS mode).

The occurrence only happens while intense Gaming. There's no other device connected to the inverter which draws significant power. The inverter is 2 months old and my PC is 8 months old. So there's nothing too old here.

The inverter guy said that it may be the PSU which trips due to voltage fluctuation on a Power Outage. But I'm not sure. Any help would be greatly appreciated.

Thanks.

I did have the same problem a few years ago , but i had a psu from a brand that nobody knew it (bought a new one).
Well it could be the temperature of cpu , or gpu , is every fan working properly ? Have you noticed if any of your components is throttling , even the mobo.

No, can my PSU be the culprit? Even if it's this one: https://www.msi.com/Power-Supply/MPG-A650GF

If your PSU has a bulk 420V DC electrolytic capacitor which is inadequately specified, it will not be able to "hold up" the supply long enough when gaming, until the UPS kicks in.

There are two (expensive) solutions.

1). Buy a higher quality PSU with a significantly longer hold-up time. The ATX spec is 17 or 18ms (I forget which). Really good PSUs hold-up for 24ms but are quite rare. Alternatively buy an 850W or 1000W PSU. It should be able to carry on working for a few more milli-seconds on your system when the mains fails.

2). Buy a better "always online" UPS which removes the switch over delay from the equation.
