Small form factor PCs have never been more capable than in 2026. The Cooler Master NR200P V2 launched this year explicitly designed for cards like the RX 9070 XT and RTX 5080, giving SFF builders access to genuine 1440p Ultra performance in an 18.5-liter chassis — roughly the size of a thick hardcover book. This build targets 1440p gaming at 90–130 FPS across demanding titles, runs nearly silently under normal gaming loads, and fits on a desk without dominating it. Total component cost lands around $1,743.
Build at a Glance
| Component | Product | Price |
|---|---|---|
| Case | Cooler Master NR200P V2 | $90 |
| CPU | AMD Ryzen 7 9800X3D | $430 |
| Motherboard | ASUS ROG Strix X870-I Gaming WiFi | $349 |
| GPU | Sapphire Pulse RX 9070 XT | $729 |
| RAM | Corsair Vengeance DDR5 32GB 6000MHz | $70 |
| Storage | WD Black SN850X 1TB | $75 |
| PSU (required) | Corsair SF750 SFX (not included) | ~$130 |
| Total | ~$1,873 |
Note: SFX PSU is not in the products array but is required — the NR200P V2 does not include one. The Corsair SF750 (80 Plus Platinum, ASIN B08R7SPXJ2) at ~$130 is the most reliable choice. NZXT’s C850 SFX works if you need 850W for higher-TDP cards.
Why These Parts
Case: The NR200P V2 replaced the original NR200P in 2024 and added explicit compatibility with modern triple-slot GPUs. It uses a 357mm vertical mount as the primary GPU orientation, which puts airflow directly against the GPU cooler instead of trapping heat between the card and the bottom panel. At 18.5L it’s larger than a console-style chassis like the Fractal Terra (10.4L) but dramatically easier to build in — particularly when routing SFX cables and seating a 280mm AIO.
CPU: The Ryzen 7 9800X3D’s 104MB stacked L3 cache makes it the fastest gaming chip on AM5. In an SFF context, its 120W TDP is manageable with a 240–280mm AIO and actually runs cooler than the 170W Ryzen 9 9950X3D in sustained loads. For a gaming-first SFF build, no alternative CPU on AM5 touches it.
Motherboard: The ROG Strix X870-I costs $100 more than the B650E-I, but delivers WiFi 7, dual USB4 ports, and a PCIe 5.0 M.2 slot — features that matter over the 4–5 year lifespan of an AM5 platform. The 10+2+1 power stage setup handles the 9800X3D’s current draw cleanly at stock and modest auto-overclocking.
GPU: The Sapphire Pulse RX 9070 XT was one of the first RDNA 4 cards to arrive in a two-slot design under 290mm. It beats the RTX 4080 Super in rasterization benchmarks at 1440p and fits the NR200P V2’s vertical mount natively with no riser cable modifications. VRAM at 16GB GDDR6 means no compression artifacts in Cyberpunk 2077 path tracing or texture streaming in open-world titles.
RAM: DDR5-6000 CL36 with AMD EXPO support hits the Infinity Fabric 1:1 synchronization ratio on Ryzen 9000 (IF clock = DRAM clock / 2 = 3000MHz). Going higher than 6000MHz introduces latency penalties unless you manually tune sub-timings, which most SFF builders skip.
Storage: The SN850X delivers 7,300/6,300 MB/s on PCIe 4.0 — sufficient that game installs, shader compilation, and load screens are never the bottleneck. For 2TB needs, the SN850X 2TB is only $55 more.
Component Deep Dives
Cooler Master NR200P V2
Cooler Master NR200P V2
The NR200P V2 is the same chassis formula as the original NR200P — a compact tower-style Mini-ITX case with a swing-out panel system — updated to support modern GPU dimensions. The key spec is the 357mm vertical GPU clearance, which accommodates the Sapphire Pulse RX 9070 XT (285mm), RTX 5080 (336mm), and even the RTX 5090 (356mm) with a 1mm margin. Cooling is handled by two 120mm fans in the base, with a 280mm radiator supported on top.
The case ships without a PSU, so budget a Corsair SF750 or equivalent SFX unit. SFX-L PSUs up to 130mm depth also fit. One build note: route your 24-pin ATX and 8-pin EPS cables before mounting the motherboard — the clearance behind the I/O shroud is under 15mm.
ASUS ROG Strix X870-I Gaming WiFi
ASUS ROG Strix X870-I Gaming WiFi
The X870-I is ASUS’s flagship Mini-ITX board on AMD’s X870 chipset, launched alongside the Ryzen 9000 series. The 10+2+1 power stage layout runs at ~75°C under the 9800X3D’s all-core boost workloads — acceptable for SFF thermal budgets. Memory support goes to DDR5-8400 via AEMP (AMD EXPO), with the sweet spot being DDR5-6000 or DDR5-6400 for gaming.
Connectivity is exceptional for a Mini-ITX board: two USB4 Gen 3×2 ports (40Gb/s), two USB 3.2 Gen 2 Type-A ports on the rear I/O, and WiFi 7 (802.11be) with Bluetooth 5.4. The dual M.2 slots run at PCIe 5.0 and PCIe 4.0 respectively. For AM5 Mini-ITX, this is the strongest option — the budget alternative is the ASRock B850I Lightning WiFi at ~$200 if you can give up USB4 and WiFi 7.
AMD Ryzen 7 9800X3D
AMD Ryzen 7 9800X3D
The 9800X3D is the right CPU for a gaming-focused SFF build. Eight Zen 5 cores at 5.2GHz boost with 104MB of stacked L3 cache puts frame rates ahead of every other consumer AMD or Intel part in cache-sensitive titles. Against the Ryzen 9 9950X3D, the 9800X3D is within 3–5 FPS in most games while drawing 50W less — a meaningful difference in an 18.5L case.
Cooling requirement: the 9800X3D needs a 240–280mm AIO or a tower cooler with at least 65mm clearance (the NR200P V2 supports 67mm CPU cooler height in air-cooling mode). The NZXT Kraken 240 RGB fits the top mount position and keeps the chip under 75°C at stock in the NR200P V2. Do not pair this CPU with a 120mm AIO — thermal headroom is insufficient at sustained all-core loads.
Sapphire Pulse RX 9070 XT
Sapphire Pulse RX 9070 XT
The Sapphire Pulse RX 9070 XT is the most build-friendly RDNA 4 card for SFF cases. At approximately 285mm length and a clean dual-slot profile, it installs vertically in the NR200P V2 with room to spare. Performance lands 8–12% ahead of the RTX 4080 Super at 1440p in rasterization-heavy titles and about 15% behind the RTX 5070 Ti, which sells for $300 more.
VRAM at 16GB GDDR6 means you won’t see VRAM pressure in current titles at 1440p Ultra. Ray tracing performance is substantially better than RDNA 3 — roughly 30% improvement in path-traced scenes — but NVIDIA’s RTX 5070 and up still hold an advantage in titles that lean on DLSS 4 multi-frame generation. AMD’s FSR 4 covers the gap for most titles, including Cyberpunk 2077 and Forza Horizon 5.
PSU requirement: a 750W unit handles the full system draw (9800X3D + RX 9070 XT) with headroom. The Corsair SF750 is the reference choice.
Corsair Vengeance DDR5 32GB 6000MHz
Corsair Vengeance DDR5 32GB (2×16GB) 6000MHz
Corsair’s Vengeance DDR5 32GB at DDR5-6000 CL36 is one of the most straightforward RAM decisions on AM5 — enable AMD EXPO in BIOS, reboot, done. The EXPO profile brings the kit from auto-detected DDR5-4800 up to 6000MHz with CL36 timings in a single toggle. Height is 34mm, which clears the top-mount AIO in the NR200P V2 without any fitment concerns.
32GB at 2×16GB is the correct configuration for a 2026 gaming build. Games like Microsoft Flight Simulator 2024, Starfield, and newer titles with wide-open worlds regularly push past 16GB system RAM usage. A single-channel 2×8GB kit would both reduce performance by 15–20% in bandwidth-limited scenarios and restrict memory capacity.
WD Black SN850X 1TB
WD Black SN850X 1TB
The SN850X posts 7,300 MB/s sequential reads on PCIe 4.0 x4, which is fast enough that game load times are entirely GPU-bound — you’ll load into the same Elden Ring bonfire in the same time as someone running a PCIe 5.0 drive. It occupies the PCIe 4.0 M.2 slot on the X870-I, leaving the PCIe 5.0 slot open for an upgrade later.
The 600 TBW endurance rating maps to roughly 330GB of writes per day for five years — well beyond what any gaming workload produces. One caution: 1TB fills fast. Cyberpunk 2077 is 70GB, Call of Duty is 100GB+, and modern PC titles run 50–100GB each. If your library is large, pay $55 more for the SN850X 2TB.

Build Tips
Cable routing is the hard part. In any Mini-ITX case, the 24-pin ATX cable runs from the PSU to the motherboard across the entire bottom of the case. Modular SFX PSUs like the SF750 let you pick the shortest cable from the bundle — use it. Route the 24-pin before installing the motherboard, not after.
Mount the CPU cooler outside the case first. Attaching an AIO pump head to the 9800X3D is easier on a table than inside the NR200P V2. Confirm the mounting bracket is correct for AM5, apply thermal paste in a pea-sized dot centered on the IHS, and only then lower the motherboard into the case.
Vertical GPU mount uses the included riser cable. The NR200P V2 ships with a PCIe 4.0 x1 riser cable for vertical GPU mounting. Make sure it seats fully in both the GPU and the motherboard slot — half-inserted risers cause black screens that look like GPU failures.
Enable AMD EXPO at first boot. After POST, enter BIOS (Del key on most ASUS boards) and enable the EXPO profile for the Corsair Vengeance kit. The board defaults to DDR5-4800 without it. While in BIOS, also set CPU fan headers to temperature-based control (not fixed percentage) to prevent the AIO pump from running at full speed during light loads.
Thermal paste re-application helps. The 9800X3D ships with pre-applied compound, but replacing it with a high-quality paste (Thermal Grizzly Kryonaut or Noctua NT-H2) typically drops peak temperatures by 5–8°C — meaningful when the target is under 85°C in a small case.
Performance Expectations
Reference configuration: 9800X3D + RX 9070 XT + DDR5-6000 CL36, Windows 11 with latest drivers.
| Game | Resolution | Settings | Expected FPS |
|---|---|---|---|
| Cyberpunk 2077 | 1440p | Ultra (no RT) | 95–105 FPS |
| Cyberpunk 2077 | 1440p | Path Tracing + FSR 4 Quality | 70–80 FPS |
| CS2 | 1440p | High | 280–350 FPS |
| Call of Duty: Black Ops 7 | 1440p | Ultra | 160–190 FPS |
| Forza Horizon 5 | 1440p | Extreme | 115–130 FPS |
| Hogwarts Legacy | 1440p | Ultra | 80–95 FPS |
| Elden Ring | 1440p | Max | 60 FPS (engine-capped) |
| Microsoft Flight Simulator 2024 | 1440p | Ultra | 55–70 FPS |
For 1080p gaming the 9800X3D eliminates the CPU bottleneck and all of the above numbers improve 15–25%. At 4K, this build runs most titles at 60–80 FPS on Ultra — capable, though a step down from dedicated 4K builds.
Upgrade Path
First upgrade (6–12 months): Replace the SN850X with a Samsung 9100 Pro 2TB in the PCIe 5.0 M.2 slot (~$200). The 14,700 MB/s reads won’t change gaming FPS, but it doubles storage and frees the PCIe 4.0 slot for a secondary drive.
Second upgrade (12–24 months): The RX 9070 XT will remain relevant at 1440p through at least 2027. If you’re chasing 4K 120Hz, an RTX 5080 or whatever RDNA 5 delivers will slot into the NR200P V2’s 357mm vertical mount without a case change. The SF750 PSU handles up to ~320W GPU TDP — sufficient for next-tier cards with some headroom.
Third upgrade (24–36 months): AM5 has a confirmed roadmap through at least 2027. A future Ryzen 9000X3D drop-in (the 9950X3D is already available) won’t require a new motherboard or RAM, keeping this SFF build viable for a longer refresh cycle than previous Intel platforms.
FAQ
Can I use an ATX PSU in the NR200P V2? No. The NR200P V2 is designed specifically for SFX and SFX-L form factor PSUs (max 130mm depth). ATX PSUs will not fit. The Corsair SF750 (SFX, 750W, 80 Plus Platinum) is the most-recommended option for this build.
Does the RX 9070 XT fit in the NR200P V2 without modification? Yes. The Sapphire Pulse RX 9070 XT measures approximately 285mm in length. The NR200P V2’s vertical GPU mount supports up to 357mm — 72mm of clearance. No trimming, bracket bending, or riser cable modification required.
What’s the minimum PSU wattage for this build? Under full gaming load, the 9800X3D draws ~120W and the Sapphire Pulse RX 9070 XT draws ~182W. With system overhead, total draw peaks around 380W. A 650W SFX unit is technically sufficient, but 750W provides enough headroom for overclocking and prevents the PSU from running at peak efficiency limits continuously.
Can I use a low-profile air cooler instead of an AIO? Only if it clears 67mm. The NR200P V2 supports 67mm CPU cooler height in air-cooling mode. The Noctua NH-L9a-AM5 at 37mm fits easily, but cannot cool the 9800X3D at 120W TDP without throttling — temperatures exceed 100°C in sustained loads. Use the Noctua NH-L12 Ghost S1 (70mm fan shrink) with a 65W TDP CPU like the Ryzen 5 9600X if you want air cooling in this case.
Is the ASUS ROG Strix X870-I worth $100 more than the B650E-I? For this build, yes. The X870’s PCIe 5.0 M.2 slot is available for a future Gen 5 SSD upgrade, dual USB4 ports replace a dock for high-bandwidth peripherals, and WiFi 7 delivers 4× the throughput of WiFi 6E in congested environments. If you’re on a tighter budget, the ASUS ROG Strix B650E-I Gaming WiFi (ASIN: B0BP9LJBP8, ~$250) handles the 9800X3D fine and loses only the premium connectivity features.
The Bottom Line
This build delivers RTX 4080 Super-class 1440p gaming performance in an 18.5-liter case with room for a 280mm AIO and full-size GPU. The Cooler Master NR200P V2 is the right starting point — its 357mm vertical GPU mount handles the Sapphire Pulse RX 9070 XT natively, and the tool-free panel access makes cable routing less painful than older SFF designs. The AMD Ryzen 7 9800X3D is the correct CPU choice for any gaming-first SFF build in 2026, and the ASUS ROG Strix X870-I gives the platform USB4 and PCIe 5.0 headroom to stay relevant for the full AM5 lifecycle. Total build cost including an SFX PSU lands around $1,870.
