Core Components

This desktop pairs an 8-core AMD Ryzen 7 9800X3D processor with an Nvidia GeForce RTX 5090 graphics card holding 32GB of video memory. 32GB of DDR5 system memory and a 2TB Samsung 990 PRO NVMe drive complete the main specification. The machine ships with Windows 11 Pro installed and is aimed at enthusiasts who want a high-end gaming and workstation platform.

Build and Connectivity

A 240mm liquid cooler handles CPU thermals inside a Corsair 4000D tempered-glass chassis. The Prime X870-P motherboard provides rear USB4 ports at 40Gbps, additional 10Gbps and 5Gbps USB, plus 2.5Gbps Ethernet and Wi-Fi 7 wireless. Internal bays include two 3.5-inch and two 2.5-inch positions, while four M.2 slots allow further storage expansion. A Thermaltake 1200W 80 PLUS Gold power supply delivers protected, low-noise power.

Deciding Specification

The RTX 5090 with 32GB of video memory is the single component that determines whether this system fits the workload. Buyers who need less graphics memory or a lower-tier GPU will find the cost and power budget excessive for their use case.

Questions about this item

What PCI Express generation does the RTX 5090 use, and what bandwidth limit does that impose?

The graphics card runs on a PCI Express x16 slot. The motherboard provides PCIe 4.0 x4 for the primary M.2 drive, so the GPU operates at PCIe 4.0 speeds rather than PCIe 5.0.

What are the case dimensions and drive bay layout for fitting this system?

The Corsair 4000D chassis measures 490 mm deep, 239 mm wide and 486 mm high. It offers two internal 3.5-inch bays and two 2.5-inch bays for additional storage.

How is the CPU cooler mounted, and what step is often missed?

The 240 mm AIO cooler attaches to the AM5 socket using the supplied backplate and four spring-loaded screws. The step people forget is removing the protective film from the cold-plate before securing the block.
