Followed up on the Dune spice wars launch and the Power off event has disappeared. Considering Starship Troopers and testing if it runs smoothly without excessive issues. Reached out to EVGA and Asus support; both are under warranty, but EVGA emphasized that swapping power supplies is a starting point and shouldn’t be causing shutdowns. I’m planning to explore a new power supply since they fixed the hard crashes. Spoke with both EVGA and Asus about power specs—they’re okay for now, though there’s no clear guidance on sudden power demands. I decided it was time for an upgrade and chose a 1000W EVGA power supply instead of spending more on a smaller swap. My goal is to see if dual GPUs will return in three years or more, possibly running two 3080s together. Still unsure about the Windows 11 update—my motherboard only supports it with certain chiplets, and I didn’t notice much change after changing inputs for Heroes of the Storm. Network firmware updates on the Z690 seem partially supported, but I couldn’t confirm stability. Intel network drivers are available, though I’m not sure how to verify them. The command prompt for checking firmware appears to work except for Windows. I’ll keep testing and hope for improvements. Thanks for all the guidance!
CPU temperature reached a high of 88°C during stress testing, which is acceptable compared to the previous 98°C–100°C spikes. The main reason for sudden shutdowns appears to be the frequent power surges typical of the RTX 3000-series, triggering the PSU’s Over-Current Protection and halting operation.
Getting guidance away from EVGA? I already own an EVGA SuperNOVA 1000 GT with 80 Plus Gold. I'm considering adding a riser and another 3080 in about two years. Not sure if it's worth it yet, but I'll check the graphics specs then. (Edit) I thought I only shared stress test results. The earlier benchmarks were much lower after the final power supply was added, around 200,000, which boosted my realbench by 50% and even more with the case off. I might re-seat my CPU to see how thermal compound affects it, but overall the system feels better than before—around what I expected. ~6 months ago that was what I hoped for. The best score comes without the case, while the worst is with the old 750W power supply.
