Updated 2026-08-20: the prices on this page have been re-derived from Sephora's live catalogue. The previous figures were substantially too low — this build was stated at ₦5,116,000 – ₦6,400,000 against a real ₦17,790,309, roughly three to four times. If you planned a purchase from this page before this date, the numbers were wrong by that margin.
Sometimes you do not want to balance cost against performance. You want the fastest machine money can currently buy in Nigeria — the one that bottlenecks nothing, handles every workload thrown at it, and will remain the fastest thing in any room it sits in for years to come. This is that build.
This is not a practical recommendation for most people. This is for the creative director who needs to render without waiting, the AI researcher who cannot afford to babysit a slower machine, the competitive gamer who demands every possible frame, or simply someone who wants the best and has the budget to match. Here is what that looks like in Nigeria in 2026.
CPU: AMD Ryzen 9 9950X
The Ryzen 9 9950X is AMD's 2025/2026 flagship consumer processor: 16 cores, 32 threads, a boost clock exceeding 5.7 GHz, and AMD's latest Zen 5 architecture with improved IPC (instructions per clock). It leads in multi-threaded workloads (rendering, compilation, AI training) and competes at the very top for single-threaded tasks (Revit, gaming, audio processing).
- Ryzen 9 9950X: ₦1,385,587
Motherboard: ASUS ROG Crosshair X870E Hero or MSI MEG X870E Ace
The X870E platform offers PCIe 5.0 on both the primary GPU slot and M.2 storage slots, USB4, Wi-Fi 7, and the best power delivery available on AM5. These boards are the platform for the 9950X to run without any limitations.
- X670E ATX DDR5: ₦914,703 — our AM5 flagship board. The X870E boards this section used to name are not catalogue SKUs.
GPU: NVIDIA RTX 5090
NVIDIA's current flagship. The RTX 5090 represents the absolute peak of consumer GPU performance in 2026: 32GB GDDR7 VRAM, DLSS 4 with multi-frame generation, 575W TDP, and leadership in both rasterization and ray tracing benchmarks. For gaming at 4K, AI inference, rendering, and video work, nothing available commercially touches it.
- RTX 5090: ₦7,600,000 (import pricing varies significantly)
Note: The RTX 5090 requires a 16-pin PCIe 5.0 power connector and a very high-capacity PSU. Its physical size also requires a full tower or large mid-tower case.
RAM: 128GB DDR5-6400 (4×32GB)
At this level of build, memory bandwidth limitations should not exist. 128GB of DDR5-6400 in quad-channel provides the headroom for any workload: AI model training, multi-tab browser sessions numbering in the dozens, simultaneous 3D rendering and video editing, virtual machine stacks. Kingston Fury Beast DDR5-6400.
- 128GB DDR5-4800: ₦3,120,011 — 128GB is our capacity ceiling and DDR5-4800 the speed we carry at it, so the 6400 kits named here previously are sourced to order rather than stocked.
Storage: PCIe 5.0 NVMe + Large Secondary Array
PCIe 5.0 NVMe drives (Samsung 9100 Pro, Crucial T705) offer sequential read speeds of 12,000–14,000 MB/s. This is overkill for most workloads but means absolutely zero storage bottlenecks in any scenario. Pair with a large capacity secondary NVMe or RAID array.
- 2TB PCIe 5.0 NVMe (OS + primary projects): ₦615,002
- 4TB PCIe 4.0 NVMe (secondary storage): ₦740,001
- 24TB HDD archive: ₦1,429,995 — our largest drive; an 8TB is ₦430,001 if that is enough
Cooling: 420mm AIO or Custom Water Cooling Loop
The Ryzen 9 9950X under full load dissipates up to 230W. In Nigeria's ambient temperatures, a 420mm AIO (four 140mm fans) is the minimum for keeping it at full boost without throttling. A custom water cooling loop — CPU block, GPU block, reservoir, pump, 480mm radiator — achieves near-silent operation even under maximum load and is the absolute pinnacle of thermal management.
- 360mm AIO, premium: ₦484,994 — the largest radiator we carry; 420mm units are sourced to order
- Custom loop: a specialist build we don't price on a page, plus professional assembly
Case: Lian Li PC-O11 Dynamic EVO XL or Fractal Torrent XL
The RTX 5090 is a large, heavy GPU (over 300mm long, three-slot). The full tower case must accommodate it with clearance for airflow. The PC-O11 Dynamic EVO XL supports 420mm radiators and has exceptional airflow with its dual-chamber design. The Fractal Torrent XL uses massive 180mm bottom fans for exceptional airflow efficiency.
- ATX Fish Bowl Case: ₦400,006
PSU: Seasonic Prime TX-1600 (1600W Titanium)
The RTX 5090 alone has a 575W TDP. Add the 9950X at 230W and you are already at 800W before accounting for storage, RAM, fans, and efficiency losses. The Seasonic Prime TX-1600 is a 1600W 80+ Titanium unit — the highest efficiency rating available, minimum noise, and Seasonic's legendary build quality. It is also one of the few consumer PSUs with a native 16-pin PCIe 5.0 connector.
- 1200W 80+ Platinum: ₦1,100,010 — the top of our range. A 1600W Titanium unit is custom-order territory, not something we can price here.
UPS: APC Smart-UPS 3000VA with Network Management Card
A build this powerful draws close to 1000W under full load. A 3000VA pure sine wave Smart-UPS provides adequate runtime, proper power conditioning, and network management capability that allows graceful automated shutdown if the battery reaches a critical level. This is the appropriate protection level for a machine at this price.
- 3KVA-class online double-conversion UPS: ₦660,000–₦1,285,000 at surveyed Nigerian market pricing — above the 2000VA our own range carries, so these are market figures rather than a Sephora quote.

This is the summit. Everything below this is a compromise of some kind — and many of those compromises are entirely sensible. But when you want to know the ceiling, this is it.
