The system features a Ryzen 5 5600X without overclocking and an RTX 3090 FE also unoverclocked. It uses two distinct power cables: Corsair RX850 (new) and NH-U12S Corsair 5000D with its fans. There are two front intake fans, two side intake fans, and one exhaust fan, all powered by a supply that draws air from underneath the GPU. The setup suggests a focus on performance rather than cooling. Despite the lower clock speeds compared to expectations, temperatures remain low, indicating no overheating concerns. If you have further questions, feel free to ask.
Start with the 1000W model, then your reported speeds match what a 3090 would offer. Did you forget to install the latest drivers? Also, your CPU is a 5600X, which limits the 3090's performance.
The outcomes appear typical for that setup. https://www.3dmark.com/search#advanced?test=spy P&cpuId=2760&gpuId=1339&gpuCount=1&gpuType=ALL&deviceType=ALL&storageModel=ALL&memoryChannels=0&country=&scoreType=overallScore&hofMode=false&showInvalidResults=false&freeParams=&minGpuCoreClock=1395&maxGpuCoreClock=1695&minGpuMemClock=1210&maxGpuMemClock=1225&minCpuClock=3700&maxCpuClock=4600
You might be experiencing reduced performance, possibly throttling. The actual power output is around 650W on the 12V rail, not the advertised 850W. Under stress testing, a 3090 could deliver about 400W, leaving only 250W for other components. I recommend returning it and choosing a more capable unit. Avoid pushing it further—Corsair’s decision to obscure the rating is questionable. It’s quite surprising they didn’t clearly display this info.
