System identity

This liquid-cooled tower pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card and 32 GB of DDR5 memory. It ships with Windows 11 Pro on an 8 TB NVMe array built from two 4 TB Samsung 990 PRO drives. The platform targets professionals who need workstation-class compute and high-end graphics in a single chassis.

Sustained-load behaviour

A 240 mm quiet-edition AIO cooler handles the CPU while the Cooler Master HAF 500 case moves air through two 200 mm front fans, a rear 120 mm fan and a dedicated 120 mm GPU fan. The Thermaltake Toughpower 1200 W 80 PLUS Gold supply uses Japanese main capacitors and a 140 mm fan rated for ultra-quiet operation. Protection circuits cover over-voltage, under-voltage, over-power and short-circuit events.

Deciding specification

The 8 TB NVMe SSD delivers sequential reads up to 7 450 MB/s and writes up to 6 900 MB/s across four PCIe 4.0 lanes. Four total memory slots allow expansion to 192 GB of DDR5. Buyers who need more than 8 TB of high-speed storage or who require additional PCIe add-in cards beyond the GPU should verify slot and M.2 availability before ordering.

Questions about this item

How loud is the 240mm liquid cooler and 140mm PSU fan under sustained load?

The CPU uses a 240mm Quiet Edition liquid cooler while the 1200W PSU has a 140mm fan rated for ultra-quiet operation, so noise stays low even during long sessions.

Does the motherboard provide enough USB4 and USB 20Gbps ports for my external SSD enclosure and capture card?

The TUF X870-PLUS board includes 2 USB4 40Gbps Type-C ports on the rear I/O plus a front-panel USB 20Gbps header for high-speed devices.

Will my existing SATA SSDs and 2.5-inch drives fit inside the CoolerMaster HAF 500 case?

The chassis offers 2 internal 3.5-inch bays and 2 internal 2.5-inch bays alongside 4 M.2 slots on the motherboard for additional NVMe drives.
