Hey everyone! I recently got my hands on a 9070XT graphics card, but I didn't prepare for it by upgrading my power supply first. Right now, I'm using a 650W gold-rated PSU for the entire system, and I knew it might be a little risky. Unfortunately, I'm facing random reboots and crashes, even after I set the graphics card's power limit to 250 watts and then to 200 watts. At one point, the card was only pulling about 80W during a crash, and I usually cap the frame rates to match my monitor's refresh rate. I'm starting to wonder if transient spikes in power demand could still be too much for my PSU. Do I really need a new power supply to fix these issues, or could something else be causing the failures? Also, should I focus on adjusting the card's clock speeds instead of just limiting the power draw? I'm not keen on doing a lot of stability testing with over- or underclocking, so any advice would be super helpful!

Absolutely, a power supply can cause issues even if you limit your graphics card's power draw. Those transient spikes could definitely fry your PSU if it's already running close to its limit. Those 80+ certifications don't always guarantee that a PSU won't struggle under load. You might want to take a look at your PSU's silent switch if it has one. If it's activated, it could be leading to overheating during long gaming sessions since the fan might not kick in. Making sure your PSU isn’t overheating is crucial! Also, try to set your frame rate limits as close to your monitor's refresh rate as possible to avoid extra load. You’re on the edge with your PSU, so every little bit helps!
Yeah, definitely consider a new power supply if the problems persist. Try to keep your GPU under control by capping the frame rates in games too—it's a smart move since pumping out more frames than your monitor can handle can strain your PSU even harder. If you're still experiencing random shutdowns, it’s probably time for an upgrade. I know testing can be a hassle but ensuring everything runs smoothly is worth it!
Totally agree! Upgrading the PSU can save you a lot of headaches down the line.
Good point about the silent switch! I hadn't considered that. Definitely worth checking out.
