Ryzen 7 9800X3D liquid-cooled desktop

This system pairs an eight-core AMD Ryzen 7 9800X3D processor with a 240 mm AIO liquid cooler and an Nvidia GeForce RTX 5090 graphics card. Thirty-two gigabytes of DDR5 memory, a 1 TB NVMe solid-state drive and a 10 TB hard drive provide storage capacity. Windows 11 Pro 64-bit comes pre-installed for immediate use.

Sustained thermal performance with 240 mm AIO

The 240 mm quiet-edition liquid cooler maintains lower CPU temperatures during extended gaming or rendering sessions compared with air cooling alone. A 1200 W 80 PLUS Gold power supply with Japanese main capacitors delivers stable power under continuous load. Front-mounted 140 mm PWM fans move air through the tempered-glass chassis to support the GPU and motherboard components.

PCIe 4.0 NVMe and 2.5 Gb Ethernet limits

The Samsung 990 PRO 1 TB drive operates at PCIe 4.0 x4 with sequential reads up to 7450 MB/s and writes up to 6900 MB/s, so throughput cannot exceed the 4.0 lane bandwidth. The Intel 2.5 Gb Ethernet port caps wired network speed at 2.5 Gbps, while Wi-Fi 7 2x2 offers higher theoretical wireless rates but real-world performance depends on router compatibility and spectrum availability.

Questions about this item

How loud is the 240 mm liquid cooler and the 140 mm fans when the Ryzen 7 9800X3D runs at full load for hours?

The 240 mm Quiet Edition AIO and two front 140 mm PWM fans are designed for low noise; the PSU also uses an ultra-quiet 140 mm fan, keeping acoustic levels down during extended gaming sessions.

Do I need to buy a monitor, keyboard and mouse separately to use this system out of the box?

The PC ships with Windows 11 Pro installed and includes front USB 3.2 Gen 2x2 Type-C, USB 3.0 and audio ports, so only a display and input devices are required to start.

Can I keep my existing SATA SSDs or 3.5" hard drives and install them in this chassis?

The motherboard provides two SATA 6 Gb/s ports and the case has two internal 3.5" bays plus two 2.5" bays, allowing you to reuse current SATA drives alongside the 1 TB NVMe and 10 TB HDD.
