Problems with system stability after adding the RTX 3070 GPU
High-end models in the A or B categories will perform well. The brief surges on the 3070, 80, and 90 are roughly 500 watts. Adding a 750 adds another 250 watts, which is more than enough for your setup.
I upgraded my power supply to a Cooler Master XG Platinum 750W and connected the RTX 3070 using two separate PCI-E cables included with the PSU. Everything appeared to function properly; I even played Fortnite with all settings active, including Epic and ray tracing, without any issues. Later, when restarting the PC, I tried playing more games with a friend to confirm it wasn’t a one-time occurrence. The system temperatures were normal—GPU reached around 80°C and CPU maxed out at 70°C. I’ve already performed a clean driver install. I’m still unsure what’s going on. Based on past advice, this PSU should have resolved the problem, but it didn’t.
