Gaming desktop for maximum FPS
The OMEN MAX 45L desktop targets gamers who want the highest frame rates in current titles. It ships with Windows 11 Pro and uses standard industry components so the system can be upgraded later. The 49.8200 lb chassis holds a patented Cryo Chamber cooling design.
RTX 5090 with 32 GB GDDR7
The discrete NVIDIA GeForce RTX 5090 provides 32 GB of GDDR7 video memory for 4K and high-refresh gaming. Integrated AMD Radeon graphics are also present on the Ryzen 9 9900X3D processor. Video output uses one HDMI 2.1b and three DisplayPort 2.1b connectors.
Tool-free access with standard parts
The case uses tool-less panels and industry-standard mounting so memory, storage and graphics cards can be swapped without proprietary brackets. The Cryo Chamber isolates the CPU cooler from the main chassis airflow. Buyers who need a smaller footprint or a lower-weight system should consider other form factors.

Questions about this item
How does the Ryzen 9 9900X3D's 5.5 GHz boost clock translate to gaming frame rates once the desktop is assembled?
The 12-core, 24-thread processor reaches 5.5 GHz max boost, feeding the RTX 5090 with high single-thread speed that helps push frame rates in CPU-bound titles while the 128 MB L3 cache reduces latency.
What does the HDMI 2.1b and DisplayPort 2.1b specification actually cap for external displays?
The video outputs follow HDMI 2.1b and DisplayPort 2.1b standards, so they support the full bandwidth those specifications define for 4K and 8K resolutions with high refresh rates and HDR.
Will the 45L chassis and Cryo Chamber cooling fit on a standard desk without special mounting?
The 45L tower weighs 49.8200 lb and uses industry-standard dimensions, so it sits on any sturdy desk or floor space without proprietary brackets or wall-mount hardware.
