System overview

This Adamant Custom desktop arrives new with a 24-core Intel Core i9-14900K processor and a GeForce RTX 5090 graphics card carrying 32GB of video memory. The platform targets creators and gamers who need high single-thread speed and massive parallel throughput in a single chassis. Windows 11 Pro is pre-installed and the build is fully customisable at order time.

Thermals and power

A 360mm quiet-edition liquid cooler handles the CPU while the CoolerMaster HAF 500 case moves air through two 200mm front fans, a rear 120mm fan and a dedicated 120mm GPU fan. The Thermaltake Toughpower 1200W 80 PLUS Gold unit supplies power with Japanese main capacitors and protections for over-voltage, under-voltage, over-power and short-circuit conditions.

Deciding specification

The 32GB frame buffer on the RTX 5090 is the single figure that determines whether this system fits workloads such as 8K video timelines, large language-model inference or extreme texture streaming. Buyers who need more VRAM or a second accelerator should look elsewhere.

Questions about this item

How do I install the 360mm AIO liquid cooler in the CoolerMaster HAF 500 case, and what step is often missed?

Mount the radiator at the front using the two 200mm fan positions, connect the pump header to the CPU_FAN socket on the Z790 AORUS board, and remember to remove the protective film from the cold plate before seating it on the i9-14900K.

Which components will need maintenance or replacement first on this liquid-cooled system?

The 360mm AIO pump and the three ARGB fans (two 200mm front, one 120mm rear) are the primary moving parts; plan to inspect coolant levels and fan bearings after several years of continuous operation.

What thermal or power limit appears first when the i9-14900K and RTX 5090 run sustained workloads?

The 1200W 80 PLUS Gold PSU and the 360mm AIO define the ceiling; under combined full-load the CPU can hit its 6.00 GHz turbo until coolant temperature triggers throttling or the PSU approaches its rated output.
