Core Configuration

This gaming desktop PC pairs an 8-core AMD Ryzen 7 9800X3D processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 64GB DDR5 memory and an 8TB NVMe array built from two 4TB Samsung 990 PRO drives. Windows 11 Pro is pre-installed for immediate use.

Sustained Operation

A 240mm liquid cooler manages CPU heat while a 1200W 80 PLUS Gold power supply delivers stable current. The Antec P20 case includes three 120mm front fans and dust filters on bottom, front and top panels. Component temperatures remain controlled during extended modelling, rendering or AI learning sessions.

Deciding Specification

The RTX 5090 provides 32GB video memory, which determines whether large textures, high-resolution frames or training datasets fit entirely on the GPU. Buyers who need more VRAM for heavier workloads cannot upgrade this card and should consider a different configuration.

Questions about this item

How loud does the 240 mm liquid cooler and the PSU's 140 mm fan get under sustained load?

The CPU uses a 240 mm quiet-edition AIO cooler and the 1200 W PSU has an ultra-quiet 140 mm fan designed for low noise, so both are built to stay subdued during long sessions.

Which display cables must I already own to connect a monitor to the RTX 5090?

The RTX 5090 uses a PCI Express x16 slot and standard DisplayPort or HDMI outputs, so you need the matching cable for your monitor's input.

Will my existing SATA SSDs or hard drives work inside this tower?

Yes, the motherboard provides four SATA 6 Gb/s ports and the case has two internal 3.5"/2.5" bays plus two 2.5" bays for adding SATA drives.
