The video embedded here shows a build in this class and budget, not this exact parts list. Use it to see how an upper class system comes together in practice, from cooler mounting to cable routing, while the parts table below reflects our independent picks for 2026.
What This Build Is
This is an upper class gaming PC build aimed at 1440p high refresh and entry 4K, centred on the Intel Core Ultra 5 245K and PNY GeForce RTX 5070 Ti. That pairing is chosen so the processor does not hold the graphics card back at your target resolution, which is the central goal for this tier.
In 2026, builds at this level usually keep the motherboard and cooler practical and put the budget into the CPU and graphics card. You are paying for a platform that can sustain high frame rates and handle modern titles with headroom, not for extra board features you will not use. If you want a system that stays responsive for several years and gives you room to upgrade, this is the class you should evaluate.
Your platform here is Intel LGA1851 with Core Ultra Series 2. The Intel® Core™ Ultra 5 Desktop Processor 245K 14 brings 14 cores with 6 P-cores and 8 E-cores and up to 5.2 GHz, with 26M cache, PCIe 5.0 and 4.0 support, and DDR5 support on Intel 800 series chipset boards. That gives you modern connectivity and memory support without stepping to a flagship CPU.
The tradeoff at this level is deliberate. You get a focused board like the MSI PRO B860M-A WiFi Motherboard, mATX with its 12 Duet Rail Power System and PCIe 5.0 x16 slot, plus a capable cooler and a strong power supply, instead of a premium overclocking board or exotic case. You also choose between an air cooler and an AIO based on noise, clearance, and aesthetics, which is why this air cooler versus aio for a upper class gaming pc build breakdown step by step parts list spends extra time on cooling and case fit. If you need the smallest possible case or you plan to move the system often, this full size parts list may not be ideal for you.
For September 2026, this balanced approach suits most gamers who want headroom to upgrade later. You get a 32GB DDR5 6000 kit that hits the sweet spot for this platform, a 2TB WD Black SN850X for a modern library, and a 1000W ATX 3.1 supply that leaves headroom above the combined draw of CPU and GPU. It is not the cheapest path to 1440p, and it is not the highest end path to 4K, but it is a sensible middle ground.

Your graphics card defines this build. The GIGABYTE GeForce RTX 5070 Ti WINDFORCE OC SFF 16G is built around the NVIDIA Blackwell architecture with 16GB GDDR7 on a 256-bit interface, PCIe 5.0 support, and DLSS 4. In our research, this class of card is what makes 1440p high refresh and entry 4K practical without forcing you to compromise on settings. Owners commonly report that the WINDFORCE cooling system stays composed under load, but you should still plan your case airflow so the card has fresh intake.
Your processor is the Intel® Core™ Ultra 5 Desktop Processor 245K 14 with 14 cores and 14 threads and up to 5.2 GHz. Per the spec sheet it is a 125W processor that fits Intel 800 series boards and supports DDR5 and PCIe 5.0. We selected it because it matches the RTX 5070 Ti tier so you do not create a CPU bottleneck at 1440p, while keeping power and cooling requirements manageable. If you stream, create, or run heavy background tasks while gaming, you may want to consider a higher core count option in the scaling section below.
The supporting parts keep the experience smooth. A 32GB DDR5 6000 kit is the capacity and speed sweet spot for this platform, and the MSI PRO B860M-A WiFi Motherboard, mATX gives you DDR5 Memory Boost up to 8600+ MT/s OC, a PCIe 5.0 x16 slot at 128GB/s, triple M.2 connectors including a Gen5 x4 128Gbps slot, Wi-Fi 7 and 5G LAN. The ARCTIC Liquid Freezer III Pro 360 with its 3 x 120 mm radiator, contact frame for LGA1851 and LGA1700, offset mounting, and integrated VRM fan is a quiet way to keep the CPU in its normal boost range. If you prefer air cooling, see our comparison of 240mm AIO vs 360mm AIO and our Thermalright Peerless Assassin 120 SE vs Noctua NH-D15 G2 analysis to weigh noise and clearance.
Compatibility Check
Will all of these parts fit and work together without surprises? That is the first question you should answer before you buy, and this build needs a few specific checks because it mixes a large AIO, a high power GPU, and a compact friendly case option.
This build is Intel LGA1851 (Core Ultra Series 2). Use a 32GB DDR5 6000 kit on the memory QVL, confirm cooler support for the socket, and size the supply above the combined CPU and GPU draw with a native 12V-2×6 cable for an RTX 50 card. The Intel Core Ultra 5 245K requires an Intel 800 series board such as the B860, and you should confirm that your board ships with a BIOS that supports Core Ultra Series 2 or be prepared to update the BIOS. BIOS updates are done at your own risk and may void warranty, so follow the board maker instructions carefully and use anti-static handling.
Socket and chipset alignment is straightforward here. The MSI PRO B860M-A WiFi Motherboard, mATX is an LGA 1851 board with a 12 Duet Rail Power System, 7W/mK MOSFET thermal pads, extended heatsink, and EZ M.2 Shield Frozr II. It supports DDR5 and PCIe 5.0 x16, which matches the CPU PCIe 5.0 and 4.0 support and the RTX 5070 Ti PCIe 5.0 interface. Because this is a newer platform, check the board support page for the exact BIOS version needed for the 245K and whether USB BIOS Flashback is available if you do not have an older CPU on hand.
Memory support deserves attention. The board lists DDR5 Memory Boost to 8600+ MT/s OC with 4 x DDR5 DIMM SMT slots, but our pick is a 32GB DDR5 6000 kit because it is the tuned sweet spot for stability and performance on this platform. Always check the memory QVL for your exact kit part number and use the recommended slots for two DIMM operation. Enabling the memory overclocking profile is considered overclocking and is done at your own risk, so verify stability after you enable it.
GPU length and slot clearance depend on your case choice. The parts table lists the Cooler Master NR200P V2 for its stock airflow and clearance, while the product data for the Cooler Master NR200P MAX V2 Mini-ITX PC Case notes an 18.25L footprint that supports GPUs up to 357.6mm with vertical mounting and a PCIe 4.0 riser cable. If you choose a compact Mini-ITX chassis, confirm that your specific RTX 5070 Ti model length and thickness clear the case and riser, and that you have the correct PCIe slot spacing. In a larger mid tower you will have more room, but you should still measure GPU length against the case spec and leave space for front radiator or fans. For more on fitting large cards and radiators, see how to choose a case for GPU clearance and radiator support.
Cooler clearance is the other key fit check, and it is central to the air cooler versus AIO decision. The ARCTIC Liquid Freezer III Pro 360 uses a 360mm radiator with 3 x 120 mm fans, a contact frame for LGA1851 and LGA1700, native offset mounting, and integrated cable management. You must confirm that your case supports a 360mm radiator in the intended position and that there is clearance for the pump head, VRM fan, and tubing. If your case only supports a 280mm top mount, like the NR200P MAX V2 bundle with its 280mm AIO, you would need a different cooler or a different case. For air coolers, check cooler height against the case CPU cooler height limit and RAM height.
Power supply headroom and connectors complete the check. The Seasonic Focus GX-1000 1000W Power Supply ATX 3.1 is ATX 3.1 and PCIe 5.1 ready with a native 12V-2×6 connector, 80 PLUS and Cybenetics Gold certification, OptiSink design, and a 135 mm FDB fan with hybrid fan control. It is rated for NVIDIA RTX 5090 and AMD RX 9000 class cards and can deliver up to 600W to the GPU via the 12V-2×6 path on compatible units. Size your supply above the combined CPU and GPU draw and follow the GPU maker recommended wattage, never assume any supply handles any card. Use the native 12V-2×6 cable, seat it fully until it clicks, and avoid sharp bends near the connector. Handle the PSU with anti-static precautions and do not reuse old modular cables from another brand or model.
Performance: What To Expect
No verified frame rate numbers are available for this build, so we will keep this section qualitative and will not invent figures. That approach protects you from misleading expectations and keeps the focus on how the parts work together.
What you should expect is a system that is balanced for 1440p high refresh and entry 4K. The RTX 5070 Ti class with 16GB GDDR7 and Blackwell features including DLSS 4 is the performance anchor, while the Core Ultra 5 245K with its hybrid architecture keeps the GPU fed at that resolution. In practice, that means you can aim for high settings at 1440p and adjust scaling or ray tracing options for entry 4K, with the CPU staying in its normal boost range when cooled by a 360mm AIO.
Your supporting choices shape the feel of the system as much as raw speed. The 32GB DDR5 6000 kit avoids memory capacity limits in modern titles and helps with multitasking, the 2TB WD Black SN850X gives you fast load times and room for a current library without constant uninstalls, and the 1000W ATX 3.1 supply with native 12V-2×6 keeps power delivery clean and quiet. If you move down a GPU tier you will notice lower headroom at higher resolutions, and if you move up a tier you will gain more future headroom, which we detail next.
Three Ways to Build This
You can scale this upper class concept up or down without changing its character. Here are three concrete paths that keep the same 1440p focus but adjust cost, cooling, and longevity.
Lower Cost Version
Choose one GPU tier down with a cheaper CPU, a budget air cooler, a 1TB drive and an entry board. You keep 1440p gaming within reach but give up some headroom and storage. This suits a first build on a tight budget where you want to get started now and upgrade the GPU later. You should not choose this if you already own a large library or you plan to play at 4K soon, since the smaller drive and lower tier card will limit you sooner.
Balanced Version, The One We Recommend
Build the parts listed here: Intel Core Ultra 5 245K, PNY GeForce RTX 5070 Ti, MSI PRO B860-P WiFi, Corsair Vengeance 32GB DDR5 6000, WD Black SN850X 2TB, Seasonic Focus GX-1000 ATX 3.1, Cooler Master NR200P V2, and Arctic Liquid Freezer III 360. This is the balanced pick for most gamers who want headroom to upgrade later without overspending on the board or cooler. You get quiet, capable cooling, modern ATX 3.1 power with native 12V-2×6, and a platform that supports PCIe 5.0 and fast DDR5. It is the best fit if you want a system that feels current in 2026 and stays flexible.
Higher End Version
Move up a GPU tier and to a Ryzen 7 9800X3D or Ryzen 9 9950X3D with a 360mm AIO and a 1000W supply. This path is for high refresh play and years of headroom, especially if you target entry 4K or you want extra CPU performance for streaming and creation. You will pay more and you will need to confirm case support for the larger cooler and the higher tier card, plus ensure your board and memory QVL align with the new platform. If you do not need that extra longevity or you are sensitive to noise and size, the balanced build is the smarter buy.
FAQ
Is an air cooler or a 360mm AIO better for an upper class build with a Core Ultra 5 245K?
Both can work if they are rated for LGA1851 and your case has the clearance. A 360mm AIO like the ARCTIC Liquid Freezer III Pro 360 with its offset mounting and VRM fan tends to run quieter under sustained loads and keeps the CPU in its normal boost range, while a large air cooler avoids pump noise and tubing. Check radiator support or cooler height against your case before you decide.
Do I need a 1000W ATX 3.1 PSU for an RTX 5070 Ti build?
You should size the supply above the combined CPU and GPU draw and follow the GPU maker recommended wattage. A modern ATX 3.1 unit like the Seasonic Focus GX-1000 with a native 12V-2×6 connector gives you headroom, clean cabling, and PCIe 5.1 readiness. Never assume a lower wattage unit handles any card, and always seat the 12V-2×6 cable fully.
Will the MSI PRO B860 board need a BIOS update for the Core Ultra 5 245K?
It may, since Core Ultra Series 2 uses LGA1851 and Intel 800 series chipsets. Check the board support page for the minimum BIOS that adds 245K support and whether the board offers USB BIOS Flashback.

Final Verdict
This upper class build hits the sweet spot for 1440p high refresh and entry 4K by putting the budget where you feel it, the CPU and GPU, while keeping the board, memory, storage, and power practical and current for 2026. It is quiet, upgrade friendly, and well matched so the processor does not hold the graphics card back at your target resolution.
Our pick: the balanced version we recommend with the Intel Core Ultra 5 245K, RTX 5070 Ti, 32GB DDR5 6000, 2TB SSD, and 1000W ATX 3.1 supply for most gamers who want headroom without overspending. If you are on a tight budget, choose the lower cost version, and if you want years of extra headroom for high refresh or creation, choose the higher end version with a 9800X3D or 9950X3D and a 360mm AIO.
These picks are not ideal for low-power CPUs that ship with an adequate stock cooler, or for cases without the clearance for a large air cooler or radiator; measure before buying.
