A 240mm quiet-edition liquid cooler handles the CPU while a Thermaltake Toughpower 1000W 80 PLUS Gold unit supplies power. The Z890 TUF motherboard provides four M.2 connectors, four SATA 6Gb/s ports and extensive USB connectivity including Thunderbolt 4 and USB 20Gbps Type-C. The CoolerMaster HAF 500 case adds front 200mm ARGB fans and rear 120mm ARGB exhaust for airflow.
