Liquid-cooled gaming tower with 24-core Intel Core Ultra 9 285K, 32GB DDR5, 1TB NVMe SSD and RTX 5060 Ti graphics
This desktop pairs a 24‑core Intel Core Ultra 9 285K with 32GB DDR5 and a GeForce RTX 5060 Ti for gaming and creative workloads. The 1TB Samsung 990 PRO NVMe drive provides fast storage for projects and game libraries. Buyers who need more than 32GB memory or a second graphics card should look elsewhere.
A 360mm liquid cooler handles the CPU while the Thermaltake Smart 850W 80 PLUS Bronze PSU with its ultra‑quiet 140mm fan supplies power. The Corsair 4000D case offers tempered glass panels and internal bays for 3.5 and 2.5 inch drives. Integrated 7.1 channel audio and Wi‑Fi 6E with Bluetooth5.3 complete the connectivity.
Under continuous load the 24‑core processor can reach up to 5.70 GHz with 36 MB L3 cache while the liquid cooler maintains stable temperatures. The RTX 5060 Ti 8GB delivers consistent frame rates in extended sessions. The motherboard provides four M.2 slots and four SATA ports for future storage expansion.

Mount the supplied bracket for LGA 1851, apply thermal paste, secure the cold plate, then connect the pump header and route the 360 mm radiator fans to the CPU_FAN or AIO_PUMP header so speed control works.
The 850 W Bronze PSU and 140 mm radiator fans are the typical wear items; the board supports up to 192 GB DDR5 across four slots and four M.2 sockets for future storage upgrades.
The 360 mm AIO and 850 W Bronze PSU set the practical ceiling; the Core Ultra 9 285K can reach 5.70 GHz but prolonged boosts are constrained by coolant temperature and PSU headroom.
