I'm looking for recommendations on a new power supply unit (PSU) for my upgraded PC gaming setup. Here are my current specs: Ryzen 7 5700X3D, ASUS ROG Strix RTX 4070 Ti Super, ASUS ROG Strix B450-F Gaming, and 64 GB Kingston Fury DDR4. Currently, I have a Strix 850W Gold Aura Edition PSU that I bought last year along with my GPU. Ever since the upgrade, I've been experiencing issues where my monitor randomly shuts off while my CPU fans ramp up to 100%. The system stays on (I can still use Discord), but the monitor loses signal and goes into power-saving mode. I've tried various troubleshooting steps, including a clean Windows install, but nothing has worked. I suspect the PSU might be faulty and am considering upgrading to a higher wattage model, possibly the same one but with 1000W. Any advice would be greatly appreciated!

I've got a similar setup with a 5070 Ti and the 850W version of the same PSU, and I've experienced random shutdowns too, especially while idle. It's a frustrating issue, and I’m starting to think maybe the PSU might not be the best choice for power stability.
What are your CPU and GPU temperatures during these issues? Those stats can help narrow down if it's heat-related or truly a power issue.
Right now, my idle temps are GPU 34°C and CPU 46°C according to hwinfo.
If you're looking for suggestions, I would recommend the Seasonic Focus Gold FX. It's fully modular and has a smart fan control feature, which means the fan won't spin until the PSU is under load. It's quiet and efficient!
There's a solid PSU tier list that can help you choose a reliable one. Just make sure you look for a reputable brand and a model that suits your wattage needs. You can find the list on various PC forums online!
Thanks for the tip!
Have you checked the PSU section on hardwarebusters.com? It's tough to determine if your PSU is the issue unless you disable all sleep and hibernation modes to rule out software problems. Sometimes, a faulty PSU will shut down the whole PC, not just parts of it.
I'm checking that site out! I found a lot of online discussions about this exact problem; some people said changing their PSU resolved it, so I'm hoping it might work for me too.
That's interesting! I wonder if there’s a common fault in that model.
