At Level Reforge 2025, we announced one of our most ambitious projects to date: the OMEN Max 45L gaming desktop. This reimagined high-performance PC represents the apex of the HP desktop lineup, engineered to deliver a gaming experience that defies all expectations.
The OMEN Max 45L will be available in December 2025. This powerhouse is packed with cutting-edge specs, featuring next-gen CPUs and GPUs, and a cooling system so innovative it deserves its own spotlight. We've engineered every component to work in perfect harmony ensuring every frame renders with impressive speed, and every task completes flawlessly.
What Sets The OMEN Max 45L Apart
The OMEN Max 45L, HP's flagship gaming desktop for 2025, introduces a new philosophy for gaming computers. While previous OMEN desktops have delivered powerful performance for years, the Max 45L pushes beyond traditional boundaries. Where previous OMEN desktops focused on providing accessible power, the Max 45L is purpose-built to break through performance ceilings.
We've designed a completely new chassis from the ground up, featuring an expanded interior volume and a revolutionary dual-chamber cooling system that provides unprecedented thermal headroom. With the Max 45L, there's no compromising, it handles the most extreme overclocks with exceptional efficiency. Our proprietary thermal solution intelligently manages airflow across both the CPU and GPU for maximum output without throttling, regardless of session length.
The OMEN Max 45L targets elite performance seekers. It's for demanding users who require uncompromising power, whether achieving the highest frame rates and resolutions, running multiple applications simultaneously without stuttering, or handling complex 3D rendering or 8K video editing effortlessly. If you live on the bleeding edge of technology and refuse to settle for anything less than the ultimate, the OMEN Max 45L is for you.
OMEN Max 45L Technical Specifications
The OMEN Max 45L features components that redefine what gaming computers can do. At its heart beats the AMD Ryzen 9 9950X3D, a CPU that combines "Zen 5" architecture with 3D V-Cache technology. This processor effortlessly manages both competitive gaming frame rates and complex creative workflows.
Paired with this powerhouse is the NVIDIA GeForce RTX 5090, the industry's most advanced GPU, capable of rendering hyper-realistic worlds with incredible speed. With its vast memory and next-generation architecture, it handles everything from real-time ray tracing in 4K to intensive AI-driven workloads.
Supporting these flagship components:
- Up to 128GB of high-speed DDR5 memory for seamless multitasking, content creation, and virtual machine operation
- Ultra-fast PCIe Gen5 SSD virtually eliminating loading screens
- 1,200W modular PSU delivering clean, stable power for current configurations and future upgrades
Revolutionary Cryo Chamber Cooling Technology
High-performance components demand equally advanced cooling. The OMEN Max 45L features our enhanced Cryo Chamber – our most advanced thermal management system yet, incorporating an enlarged 360mm liquid cooler working in tandem with the upgraded Cryo Chamber.
By positioning the liquid cooler above the main chassis, we've created a reservoir of cool, ambient air that draws directly into the system, bypassing heat from other components. This intelligent design keeps the CPU and GPU at optimal temperatures, even during 24-hour streaming sessions or week-long rendering projects.
We've introduced self-cleaning fans to ensure long-term stability and minimal maintenance. These fans feature a reversible function that, at the push of a button, briefly expels dust and debris from the fan blades, keeping your system running efficiently for years to come. The Max 45L delivers both exceptional performance and long-term reliability.
Design and Build Quality
The OMEN Max 45L's chassis combines form and function with its spacious, elegantly crafted construction featuring brushed metal and tempered glass that showcases your high-end components. The expanded interior volume serves dual purposes: superior airflow and effortless upgradability. Clean cable management and tool-less design enable quick component swaps in minutes.
RGB customization through OMEN Gaming Hub software gives you granular control over lighting zones. You can sync colors and effects across your entire setup, from the chassis to your keyboard and mouse. The OMEN Max 45L becomes an extension of your personality, offering complete freedom of expression.
The spacious design and forward-thinking component selection make this more than just today's powerhouse, it's a future-proof investment ready for tomorrow's hardware advancements.
Gaming and Creative Performance Benchmarks
What does this power deliver? Play your favorite games at true 4K resolution with every setting maximized, including full ray tracing, without dropping a single frame. The combination of the RTX 5090 and NVIDIA DLSS 3 technology provides a competitive edge, delivering higher frame rates and lower system latency through NVIDIA Reflex for more responsive and immersive gameplay.
For creators, the OMEN Max 45L accelerates demanding workloads like 3D modeling, video editing, and complex graphic design. Rendering and transcoding times are significantly reduced, letting you focus on your creative flow instead of waiting for your computer. With ample VRAM and processing capabilities, this desktop handles intensive generative AI models for everything from art generation to code assistance.
Frequently Asked Questions About the OMEN Max 45L
Since announcing the OMEN Max 45L, we've received numerous questions. Here are the answers:
When will the OMEN Max 45L be available?
The OMEN Max 45L is scheduled for launch in December 2025. We're applying final refinements to ensure the system delivers on every promise. The wait will be worthwhile.
How does the OMEN Max 45L compare to other gaming desktops?
Unlike pre-built systems using off-the-shelf components and generic cases, the OMEN Max 45L has been engineered from the ground up as a cohesive, high-performance ecosystem.

What makes the cooling system unique?
The OMEN Max 45L's cooling centers on our patented Cryo Chamber. Rather than housing the liquid cooler within the main case, it's positioned in a separate, isolated chamber above the chassis. This enables the radiator to draw in cool, ambient air from outside the system, running up to 10°C cooler than internal case air. This revolutionary design maintains lower CPU temperatures, prevents thermal throttling, and sustains boost clocks during intense gaming sessions. Combined with self-cleaning fans, this cooling system delivers unmatched performance and long-term stability.
Is the OMEN Max 45L upgradeable?
Absolutely. The OMEN Max 45L is designed as a future-proof investment. The spacious chassis, tool-less side panels, and accessible components—from DDR5 DIMM slots to multiple PCIe Gen5 M.2 bays—allow easy parts swapping and upgrades as your needs evolve. Industry-standard components throughout the build provide freedom to customize and expand your system for years to come.
