I have an Intel i7-12700F with a 7900 XT GPU and 32GB of DDR4 RAM. I'm currently using an 850W power supply from an unknown brand, but it's been crashing and restarting my PC during heavy gaming sessions without any error messages due to power spikes. Would upgrading to a better power supply like the NZXT C1200W solve the problem?

You don't really need a 1200W PSU for your setup. An 850W unit should be sufficient as long as it's a reputable brand. Modern power supplies are designed to handle short spikes in power usage, and the fact that you don't know the make of your current PSU suggests it might not be very reliable. Investing in a quality PSU could resolve your crashing issues without needing to jump to 1200W.
I've heard that shifting to a higher watt PSU fixed similar issues for others. But maybe that was just specific to their setups?
Getting a 1200W PSU is a bit excessive for your needs. An 850W quality unit like a Corsair or EVGA should do just fine. Just make sure it’s a solid model, as reliability is key here!
I noticed the NZXT is cheaper than the Corsair RM1000X, and I thought that might make it a better option. What do you think?

Definitely! I'm curious about what PSU you're using now. Sounds like it could be the root of your problems.
