I've got a Ryzen 5 3600x paired with a Radeon RX 5700 XT (8GB VRAM) and I'm using a B450M Pro4 motherboard with 16GB of Corsair RAM. My power supply is a Be Quiet! System Power 9 with 700 watts. The problem is that my PC unexpectedly shuts off while I'm playing games like Fortnite and Forza Horizon 5, despite maintaining over 120 FPS. I've updated the drivers and checked the temperatures, both the CPU and GPU usually stay under 75°C. I'm starting to wonder if the power supply might be at fault. Does anyone have any solutions or ideas on what could be causing this? Thanks!

It sounds like it could be one of three things: a faulty power supply, a defective motherboard, or a graphics card issue. Of these, I'd lean towards the power supply being the most likely culprit. You might want to check that first!

Thanks for the advice! I wouldn’t expect those components to be defective since they're still performing well in other games, like getting 80 FPS at ultra settings in BeamNG.
