System build and audience

This gaming desktop pairs an AMD Ryzen 7 9850X3D processor with an NVIDIA GeForce RTX 5090 graphics card, 32GB DDR5 memory and a 2TB NVME solid-state drive in a Cooler Master Cosmos Alpha ATX Silver chassis. It ships with Windows 11 Home pre-installed and is assembled from new components by certified technicians.

Who it suits and who it does not

The machine targets enthusiasts who want high-end 3D V-Cache CPU performance and flagship GPU power in a ready-to-run system. Buyers who need more memory capacity, additional storage bays or a different motherboard chipset should look at alternative configurations. The front-panel connectivity is limited by the B650 board header count.

Deciding specification

The motherboard provides only one USB 3.2 header and one Type-E header, so only two of the case front USB 3.2 ports and one of the two Type-C ports are active without extra adapter cables. This I/O restriction is the key detail to verify before purchase.

Questions about this item

What comes in the box and which cables or parts must I source myself?

The PC arrives fully assembled with Windows 11 Home installed, the Ryzen 7 9850X3D, RTX 5090, 32 GB DDR5, 2 TB NVME, PL360 Flux AIO cooler, 1000 W Gold PSU and Cooler Master Cosmos Alpha case. Only a monitor, keyboard and mouse are needed separately.

Should I pick a different RAM capacity or GPU variant for this build?

This unit is a single configuration: 32 GB DDR5 in a 2×16 GB RGB kit and the RTX 5090 are factory-fitted; no other capacities or graphics options are offered for this model.

What does the RTX 5090 actually deliver inside this chassis with the 1000 W Gold PSU and B650 board?

The RTX 5090 runs at its rated spec powered by the 1000 W Gold supply, while the B650 motherboard provides the PCIe link and single USB 3.2 header that limits front-panel ports to two active USB 3.2 and one Type-C.
