RTX 5090 & Ryzen 9 9950X3D Gaming PC! Feat. HAVN BF 360 FLOW

Components

CPU: AMD Ryzen 9 9950X3D

The AMD Ryzen 9 9950X3D is AMD’s latest gaming-focused CPU. Packed with sixteen cores and thirty-two threads, it makes it a strong performer for multi-core workloads, too. Built on Zen 5 with 128 MB of L3 3D V-Cache, this CPU is specifically designed to excel in gaming and handling cache-based workloads with ease. As part of the current Ryzen 9000 series, it’s well-equipped to handle the demands of upcoming AAA titles for years to come. When paired with our chosen GPU, your PC will be an absolute powerhouse nestled within a ‘sleeper build’ of a PC chassis. To learn more about the immense power of this CPU, read our AMD Ryzen 9 9950X3D Review.

CPU Cooler: NZXT Kraken Elite 360 RGB

The NZXT Kraken Elite 360 RGB brings efficient, low-noise CPU cooling thanks to the NZXT Turbine Pump, while the 2.72-inch IPS LCD and RGB ring offer more ways to personalise your build’s centrepiece. As the PC case we have chosen doesn’t promote flashy visuals, the CPU cooler and RAM are realistically the only components that we can sensibly incorporate a little bit of personality into, and this is because the HAVN BF 360 FLOW does offer a little window into the internals of the case (more about this later).

This 360mm cooler is an all-in-one unit powered by a custom-designed NZXT Turbine pump, delivering a high flow rate and head pressure for powerful yet quiet CPU cooling. It’s ideal for maintaining the AMD Ryzen 9 9950X3D CPU’s stability under load. What’s more, you’ll benefit from handy personalisation features, such as displaying your favourite GIF or image, tracking real-time system performance, and integrating with Spotify and YouTube using the IPS LCD screen.

Motherboard: NZXT N9 X870E

We’ve chosen the NZXT N9 X870E motherboard for this build because it perfectly balances cutting-edge performance with a sleek, modern design, making it both an ideal match for our minimalist HAVN case and a solid foundation for any modern gaming PC. Designed specifically with the latest AMD processors in mind, it delivers overclocking-ready power, optimised thermals, and future-proof PCIe 5.0 support. Connectivity is no midpoint here, featuring high-speed WiFi 7, 5Gb LAN, and versatile USB4 ports to keep you prepared for the fastest peripherals and networks.

The motherboard’s full-metal cover, highlighted by subtle RGB lighting, adds a refined touch of sophistication without overpowering the build’s understated aesthetic. It comes in both black and white variants, so if our all-black theme isn’t your preference, the white version offers a stylish alternative.

For enthusiasts, this board features a robust 20+2+1 power phase design, ensuring exceptional stability and ample overclocking headroom. Dedicated heatsinks with thermal pads cover all M.2 slots, providing excellent thermal management for high-speed NVMe storage, and with plentiful enthusiast-grade ports designed to support high-speed data transfer and future-proof connectivity, the NZXT N9 X870E is the perfect backbone for a build that demands both style and substance.

RAM: Corsair Dominator Titanium

Our PC build contains the Corsair Dominator Titanium RAM kit, where luxury is accentuated by the exceptionally unique feature of swappable top bars with CORSAIR DOMINATOR TITANIUM Fin Accessory Kits. These not only elevate the aesthetic appeal but also provide functional benefits – the fins help dissipate heat away from the memory chips, enhancing performance, longevity and steady temperatures. For this build, we installed the 6000 MT/s kit, which delivers excellent overall system responsiveness. Additionally, Corsair has integrated AMD EXPO for seamless overclocking with AMD CPUs, perfectly complementing our Ryzen 9 9950X3D.

SSD: CORSAIR MP700 PRO SE

For this build, we are using the CORSAIR MP700 PRO SE with a storage capacity of 4TB; this is because it is the best SSD for performance that we’ve seen since our original review of the CORSAIR MP700 PRO SE in May 2024. The MP700 PRO SE has demonstrated outstanding sequential read speeds of up to 14,076 MB/s and write speeds of up to 11,956 MB/s, placing it among the fastest PCIe Gen 5 drives available at the time.

It was only recently that this SSD was surpassed by the Samsung 9100 Pro in 8TB capacity, so if you value super-fast data transfer rates and reliable, strong performance, either of these SSDs is a viable option. For a PC build of this tier, we wouldn’t recommend opting for a storage capacity lower than 4 TB, as it’s likely that you’ll be using this PC for storage-demanding tasks like multimedia creation or gaming. The space that games require can be pretty sizable nowadays, so it’s worth ensuring that you have enough in excess to stop you from being caught lacking.

GPU: NVIDIA GeForce RTX 5090 FE

The NVIDIA GeForce RTX 5090 FE may prove challenging to purchase, as the FE model is typically only available for retail on the original release date. If it becomes available for purchase again, it tends to sell out quickly. I’m going to recommend the Gigabyte GeForce RTX 5090 GAMING OC, which retains some of the sleek aesthetic we are aiming for, while also being compatible with our case.

The RTX 5090 is the pinnacle of 4K gaming, boasting the fastest gaming GPU on the market. It offers jaw-dropping features, including AI-enhanced graphics and performance with DLSS 4 and Multiframe generation, as well as full ray tracing with neural rendering. The possibilities are almost endless for the experiences this GPU can produce, especially when paired with an equally powerful processor like the AMD Ryzen 9 9950X3D.

Case: HAVN BF 360 FLOW

Only available for order via Amazon in the United States.

Newly released for purchase at the time of writing this in October 2025, this case steps away from the popular panoramic or aquarium-style cases. HAVN have constructed a more conservative chassis for aficionados who prefer a classic and conservative approach to modern PC gaming setup compositions.

Rigorously engineered and tested by HAVN engineers, this high airflow case is tailored to deliver unrivalled performance through its thoughtfully conceived thermal and acoustic control. Inheriting all the features that made the HAVN HS 420 special, which we at GeekaWhat thoroughly admired, this is a welcome step up from that case. It’s designed with excellent performance in mind, as well as sophisticated engineering, aerodynamically contoured aesthetics, and a user-friendly interface.

Now, regarding its specifications, this is a mid-tower chassis with dimensions of 515mm in length, 254mm in width, and 255.6mm in height. It comes in two sleek monochromatic colourways, allowing users to seamlessly integrate it into their preferred build theme. It features some standout elements, including the highly adjustable support GPU bracket and airflow ramp, which support the weight of your RTX 5090 and direct cool air directly into the airflow pathway of the GPU’s fans.

The HAVN BF 360 FLOW also features the SimpliCable Routing system inherited from the HAVN HS 420, ensuring clean and efficient cable management. All fan brackets include vibration-dampening to reduce noise and enhance component longevity. Optimised for AIO CPU cooling, the chassis comes equipped with two 180mm front fans and one 140mm rear fan, delivering excellent out-of-the-box cooling performance. It also supports radiators up to 360mm.

PSU: Corsair RM1000X

Selecting a power supply with adequate wattage and a high efficiency rating is crucial for a stable and efficient build. Given its intrinsically power-hungry nature, the GPU is the primary component we prioritise when determining wattage requirements. The Corsair RM1000X not only meets NVIDIA’s recommended wattage for the RTX 5090 but also carries an 80 PLUS Gold certification, ensuring both reliable power delivery and high energy efficiency for this demanding GPU.

Performance

This luxury gaming PC, powered by the Ryzen 9 9950X3D and the RTX 5090, delivers outstanding performance across all of our tested games, especially at demanding 4K settings. In titles like Apex Legends, it achieves an impressive average frame rate of almost 300 FPS. Even in graphically intensive games such as Cyberpunk 2077 and Marvel Rivals, the system maintains smooth frame pacing with 1% lows well above 70 FPS in most cases, minimising stutter and ensuring a consistent experience. The 0.1% lows dip lower, but still stay at playable levels, which speaks to the stability and efficiency of the hardware under peak loads. At 1080p, Fortnite runs with an average frame rate of 373 FPS. Overall, this combination handles competitive titles at high resolutions effortlessly. It’s a perfect choice for enthusiasts seeking top-tier performance and future-proof components in demanding gaming scenarios.
