After more than ten years with my dependable Aurora R6, I'm finally planning a complete PC and monitor upgrade. New graphics features, AI workloads, and general performance have made my old GTX 1060 system feel outdated, and I'd rather build something powerful now than replace individual parts over time. The planned system will run Windows 11 and include an Intel Core i9-285K, GeForce RTX 5080 16GB GDDR7, 32GB of dual-channel DDR5-7200 memory, a 2TB PCIe NVMe SSD, a 1000W Platinum-rated power supply, and a 240mm liquid cooler. I'm interested in gaming, general responsiveness, background tasks, file transfers, and local processing, not just maximum game performance. Will these components work well together, and are there any parts I should change for better value, stability, or long-term usefulness? I'd also like to know roughly how much more electricity this system might use than my old Aurora R6, which currently draws around 120W in my typical use.

The 285K makes more sense if your priority is heavily threaded work or local processing rather than gaming alone. More cores can help with some productivity workloads, but the exact software matters, and a gaming-oriented X3D processor may still be faster in games. Make sure the prebuilt or motherboard has adequate VRM cooling, a current BIOS, and a good contact frame or mounting solution if applicable. A 1000W Platinum PSU is plenty for an RTX 5080 system and leaves useful headroom, assuming it is a reputable model with the proper modern GPU power connector.
Expect a substantial increase in power use compared with a system that averages around 120W. A high-end gaming PC with an RTX 5080 can easily draw roughly 300–500W at the wall while gaming, depending on the CPU, frame rate, power limits, and whether the monitor is included. Heavy CPU and GPU workloads can go higher, while idle or light desktop use should be much lower. The monitor adds its own consumption, often somewhere around 30–100W depending on size and brightness. The best way to compare your old and new systems is with a plug-in watt meter, since component maximum ratings are not the same as typical real-world usage.
For a gaming-focused system, I’d seriously compare the Core i9-285K with a Ryzen 7 9800X3D. The X3D chip is usually the stronger choice for games and is less sensitive to very fast memory, so DDR5-6000 with reasonably tight timings, around CL30–CL40, is generally a better-balanced target. DDR5-7200 can work, but it may require more tuning and may not provide a meaningful real-world improvement. If the faster kit is genuinely the same price, it isn’t necessarily a bad purchase, but check that the motherboard supports it reliably.
I originally chose the 285K because I read that its extra cores would help with local processing, background tasks, and file transfers. The memory kit was also discounted to the same price as the slower option, so I’ll compare the two platforms more carefully rather than choosing only by gaming benchmarks.
