Three PC rig proposals, with every gap visible
Each proposal names all nine core components, including a monitor. Compatibility verification is incomplete for all three. Resolve every unknown before using a proposal as a shopping list.
0 fully verified builds. “Verified” refers to the documented checks below. All nine parts are proposed; Six checks remain UNKNOWN per proposal: installed BIOS, RAM validation, full GPU/cable envelope, complete power budget, final display mode and physical assembly/cooling. These proposals have not been assembled or physically tested.
Read the status before the parts
- PASS
- The specific documented rule passes. A part-selection PASS confirms identity only.
- FAIL
- The documented values conflict. Change a part or the configuration.
- UNKNOWN
- A part, specification or configuration check is missing. This blocks a complete-build recommendation.
Overall status is FAIL when any rule fails, otherwise UNKNOWN while any rule is unresolved. Every rule must pass before the document checks can pass as a whole. Even then, that result would not establish assembly quality or real-world performance.
NVIDIA’s minimum PSU figures use a Ryzen 9 9950X system as their reference and may change with the configuration. The GPU dimensions below apply to the named Founders Edition only. Partner cards need their own specifications.
The proposals share a Ryzen 9 9950X platform to keep the component checklist consistent. CPU/GPU balance and value have not been evaluated. Operating system, peripherals and any extra fans are outside the nine-part inventory and need separate planning.
Documented layout for these checks
Conventional North XL Mesh with its three stock front fans, no front radiator and no side fan bracket. Keep both NH-D15 G2 standard fans and raise the front one 3 mm for the 35 mm RAM: published total height 171 mm versus the case’s 185 mm limit. The high side bracket would reduce that limit to 155 mm and fail this check.
Use the conservative two-tray 175 mm PSU limit for the 160 mm RMx unit. Place the 990 PRO in M.2_3, the FE GPU in PCIEX16(G5), and leave other expansion/M.2 slots empty. Plan A2/B2 memory at SPD 4800; EXPO 6000 is not a stability promise. GPU power uses the in-box NVIDIA adapter and the exact PSU’s dedicated PCIe leads, never EPS leads. The separately proposed display cable is Club 3D CAC-1091; its presence does not establish a negotiated display mode.
Changing the stated SKU, radiator, bracket, fan adjustment, storage slot or power-cable path requires another check. Front USB-C speed/revision remains unverified because older Fractal documentation differs from its current manual; no 20 Gbps result is promised.
Total price: unavailable. Performance and store availability have not been checked.

Evidence: NVIDIA RTX 5070 family specifications · Fractal North XL manual: conventional Mesh/TG
Action: Confirm the usable length with the chosen radiator, fans and drive cages; then check width, thickness and cable space.
- CPU and motherboard socketPASS
Reason: CPU socket AM5 and board socket AM5. This does not resolve installed BIOS.
Evidence: AMD Ryzen 9 9950X specifications · ASUS TUF GAMING X870-PLUS WIFI specifications
Action: Check the independent BIOS rule before recommending the complete rig.
- CPU support and installed BIOSUNKNOWN
Reason: ASUS lists 9950X for PCB all and BIOS ALL. The actual installed firmware and board revision have not been inspected; do not infer them from a purchase listing.
Evidence: ASUS CPU support: 9950X, PCB all, BIOS ALL
Action: Confirm the board revision, CPU support list, minimum BIOS and installed BIOS. Unknown BIOS cannot pass.
- RAM generation, capacity and supportUNKNOWN
Reason: The exact 2×16 GB DDR5 UDIMM kit is proposed at SPD 4800 in A2/B2, not promised at EXPO 6000. Exact module revision/QVL match and stability on the installed BIOS remain unverified.
Evidence: Corsair VENGEANCE CMK32GX5M2B6000Z30 · ASUS TUF GAMING X870-PLUS WIFI specifications · AMD Ryzen 9 9950X specifications
Action: Check the exact memory kit against board and CPU support, including capacity and chosen settings.
- Storage interface and lane sharingPASS
Reason: 990 PRO PCIe4x4 / M.2 2280 in M.2_3, documented PCIe4x4 / 2280. Leave M.2_2, M.2_4 and the lower PCIe slot empty; use the top GPU slot. This avoids the specific sharing pairs in the ASUS table.
Evidence: Samsung 990 PRO datasheet Rev 2.0 · ASUS TUF GAMING X870-PLUS WIFI specifications
Action: Use only the stated slot plan; other populated slots require a fresh lane-sharing check.
- Cooler socket, CPU and motherboard supportPASS
Reason: Noctua lists NH-D15 G2 standard compatible with both the exact 9950X CPU and ASUS motherboard. Use the supplied AM5 SecuFirm2+ hardware; thermal performance remains unmeasured.
Evidence: Noctua exact CPU compatibility matrix · Noctua exact motherboard compatibility matrix · Noctua NH-D15 G2 specifications
Action: Confirm the mounting kit and cooling requirements for the selected CPU.
- Cooler, RAM and case clearancePASS
Reason: RAM 35 mm, default clearance 32 mm; front fan raised 3 mm. Resulting cooler height 171 mm versus case limit 185 mm with side bracket absent. Published dimensions only; no manufacturing tolerance is invented.
Evidence: Corsair DDR5 module dimensions · Noctua NH-D15 G2 RAM/case adjustment · Fractal North XL cooler and side bracket limits
Action: Keep the stated fan adjustment and bracket position; inspect the actual fit during installation.
- Motherboard and case fitPASS
Reason: ATX 305 × 244 mm board in an ATX-compatible conventional North XL. Planned front wiring: case HD Audio → F_AUDIO; Power SW/Power LED → marked F_PANEL pins; USB-A pair → U5G_1011; USB-C → USB 20Gbps Type-C front-panel header. Connector matching is documented; actual wiring and USB-C speed/revision are not tested.
Evidence: ASUS TUF GAMING X870-PLUS WIFI specifications · ASUS TUF X870-PLUS WIFI English manual V2 · Fractal North XL manual: conventional Mesh/TG
Action: Confirm board form factor, standoffs and front-panel connections.
- PSU and case fitPASS
Reason: PSU length 160 mm versus 175 mm with 2 HDD trays. This checks the ATX unit length, not the real cable bend radius or connector space.
Evidence: Corsair RM850x, CP-9020270-NA · Fractal North XL manual: conventional Mesh/TG
Action: Use the declared tray layout and inspect cable routing during assembly.
- GPU thickness, width and cable spaceUNKNOWN
Reason: The FE length is documented separately. Case clearance from the installed GPU power connector to the side panel, full cable bend space and the assembled intake envelope have not been measured. External case width is not a usable internal clearance.
Evidence: NVIDIA RTX 5070 family specifications · Fractal North XL manual: conventional Mesh/TG · ASUS TUF GAMING X870-PLUS WIFI specifications
Action: Check GPU width, slots, expansion-slot layout, cable bend space and intake clearance. Length alone is insufficient.
- Complete-system power budgetUNKNOWN
Reason: The selected PSU meets NVIDIA’s minimum for a reference 9950X system, but that is not a measured bound for this complete board, memory, drive, fans, CPU settings and transient load. No invented headroom percentage is used.
Evidence: NVIDIA RTX 5070 family specifications · Corsair RM850x, CP-9020270-NA · AMD Ryzen 9 9950X specifications
Action: Calculate the final configuration with CPU limits, accessories and manufacturer guidance. A GPU minimum alone is insufficient.
- Exact PSU cable and GPU connectorPASS
Reason: NVIDIA in-box GPU adapter requires 2 dedicated PCIe 6+2 leads; the exact RMx PSU supplies 3. Use only those PSU-specific original leads, not EPS leads or a daisy-chain substitute. Physical seating and cable clearance are separate.
Evidence: NVIDIA RTX 5070 family specifications · Corsair RMx included cable guide
Action: Follow both manufacturers’ connection instructions and fully seat every connector; never mix modular PSU cables.
- Motherboard power connectionsPASS
Reason: Board requires 1 ATX 24-pin and 2 EPS 8-pin connections; PSU supplies 1 and 2. PCIe cables are not substitutes for EPS.
Evidence: ASUS TUF GAMING X870-PLUS WIFI specifications · Corsair RMx included cable guide
Action: Connect the original 24-pin and both original EPS 4+4 cables according to the ASUS manual.
- Monitor signal path and intended modeUNKNOWN
Reason: 1440p59.951 timing and RGB 8 bpc are documented; the AOC PDF’s US regional applicability and DSC-off state are unconfirmed. CAC-1091 is a proposed separate accessory, not an assumed in-box cable.
Evidence: NVIDIA RTX 5070 family specifications · Club 3D CAC-1091 DP80 cable datasheet · AOC Q27G3XMN manual, regional applicability unconfirmed
Action: Choose resolution, refresh rate, color mode and cable; verify both ports and any DSC requirement. Matching connector names alone cannot pass.
- Cooling and installation planUNKNOWN
Reason: Plan: three stock front intake fans, no radiator/side bracket, two G2 cooler fans, front fan raised 3 mm, GPU horizontal and original PSU leads. Actual header wiring/current checks, assembly, thermals and noise remain untested.
Evidence: Fractal North XL manual: conventional Mesh/TG · ASUS TUF X870-PLUS WIFI English manual V2 · Noctua NH-D15 G2 RAM/case adjustment
Action: Document fan placement, airflow and installation clearances for the final configuration.

Evidence: ASUS TUF GAMING X870-PLUS WIFI specifications · ASUS TUF X870-PLUS WIFI English manual V2 · Fractal North XL manual: conventional Mesh/TG
Action: Confirm board form factor, standoffs and front-panel connections.
- PSU and case fitPASS
Reason: PSU length 160 mm versus 175 mm with 2 HDD trays. This checks the ATX unit length, not the real cable bend radius or connector space.
Evidence: Corsair RM1000x, CP-9020271-NA · Fractal North XL manual: conventional Mesh/TG
Action: Use the declared tray layout and inspect cable routing during assembly.
- GPU thickness, width and cable spaceUNKNOWN
Reason: The FE length is documented separately. Case clearance from the installed GPU power connector to the side panel, full cable bend space and the assembled intake envelope have not been measured. External case width is not a usable internal clearance.
Evidence: NVIDIA RTX 5090 specifications · Fractal North XL manual: conventional Mesh/TG · ASUS TUF GAMING X870-PLUS WIFI specifications
Action: Check GPU width, slots, expansion-slot layout, cable bend space and intake clearance. Length alone is insufficient.
- Complete-system power budgetUNKNOWN
Reason: The selected PSU meets NVIDIA’s minimum for a reference 9950X system, but that is not a measured bound for this complete board, memory, drive, fans, CPU settings and transient load. No invented headroom percentage is used.
Evidence: NVIDIA RTX 5090 specifications · Corsair RM1000x, CP-9020271-NA · AMD Ryzen 9 9950X specifications
Action: Calculate the final configuration with CPU limits, accessories and manufacturer guidance. A GPU minimum alone is insufficient.
- Exact PSU cable and GPU connectorPASS
Reason: NVIDIA in-box GPU adapter requires 4 dedicated PCIe 6+2 leads; the exact RMx PSU supplies 4. Use only those PSU-specific original leads, not EPS leads or a daisy-chain substitute. Physical seating and cable clearance are separate.
Evidence: NVIDIA RTX 5090 specifications · Corsair RMx included cable guide
Action: Follow both manufacturers’ connection instructions and fully seat every connector; never mix modular PSU cables.
- Motherboard power connectionsPASS
Reason: Board requires 1 ATX 24-pin and 2 EPS 8-pin connections; PSU supplies 1 and 2. PCIe cables are not substitutes for EPS.
Evidence: ASUS TUF GAMING X870-PLUS WIFI specifications · Corsair RMx included cable guide
Action: Connect the original 24-pin and both original EPS 4+4 cables according to the ASUS manual.
- Monitor signal path and intended modeUNKNOWN
Reason: ASUS documents DP 4K60 and a DSC-off control; the consulted manual does not establish RGB 8 bpc for the exact US firmware/variant. CAC-1091 is proposed separately; no negotiated link was tested.
Evidence: NVIDIA RTX 5090 specifications · Club 3D CAC-1091 DP80 cable datasheet · ASUS PG27UCDM manual, Russian edition
Action: Choose resolution, refresh rate, color mode and cable; verify both ports and any DSC requirement. Matching connector names alone cannot pass.
- Cooling and installation planUNKNOWN
Reason: Plan: three stock front intake fans, no radiator/side bracket, two G2 cooler fans, front fan raised 3 mm, GPU horizontal and original PSU leads. Actual header wiring/current checks, assembly, thermals and noise remain untested.
Evidence: Fractal North XL manual: conventional Mesh/TG · ASUS TUF X870-PLUS WIFI English manual V2 · Noctua NH-D15 G2 RAM/case adjustment
Action: Document fan placement, airflow and installation clearances for the final configuration.
