HP Omen Max 45L Review: Flagship Gaming Performance at a Premium Price

The HP Omen Max 45L represents the pinnacle of HP's gaming desktop lineup, combining cutting-edge components with innovative cooling in a striking chassis. Our review configuration, featuring an AMD Ryzen 9 9900X3D processor, 64GB DDR5-6000 memory, and NVIDIA GeForce RTX 5090 graphics, delivers exceptional performance but comes with a flagship price tag of $6,499.99.

Design and Build Quality

The Omen Max 45L makes an immediate visual statement with its 8.03 x 18.50 x 21.85-inch aluminum chassis weighing 49.82 pounds. The matte-black exterior features a glass front panel showcasing three vertically stacked 120mm RGB intake fans, along with a prominent "OMEN" logo. A small AMD Ryzen sticker in the bottom right corner slightly detracts from the otherwise premium aesthetic.

Inside, HP's innovative Cryo Chamber design separates the 360mm radiator from the main chassis, creating an air gap that HP claims reduces CPU temperatures by up to 7°C compared to traditional cooling solutions. Three additional 120mm fans in the Cryo Chamber push fresh air upward over the radiator, while the main chassis houses the GPU and other components.

Specifications and Connectivity

Our review unit features a custom HP 8E55 motherboard with AMD X870 chipset, offering comprehensive connectivity:

• Top Ports: 2x USB-A (5 Gbps), 1x USB-C (10 Gbps), 3.5mm audio combo jack
• Rear Ports: 4x USB-A (480 Mbps), 2x USB-A (5 Gbps), 1x USB-C (10 Gbps), 1x Thunderbolt 4, 2.5 GbE LAN, 3x audio jacks
• Wireless: MediaTek Wi-Fi 7 and Bluetooth 5.4

The system includes a 1,200W 80 Plus Gold modular power supply and comes with two 2TB PCIe 4.0 SSDs in M.2 slots, delivering impressive storage performance.

Gaming Performance

In our gaming benchmarks, the Omen Max 45L demonstrated why it commands such a premium price:

• Shadow of the Tomb Raider: 329 FPS at 1080p, 170 FPS at 4K
• Cyberpunk 2077: 146 FPS at 1080p with ray tracing, 50 FPS at 4K
• Far Cry 6: 187 FPS at 1080p, 111 FPS at 4K
• Red Dead Redemption 2: 217 FPS at 1080p, 124 FPS at 4K
• Metro Exodus Stress Test: 157.68 FPS average over 15 loops

The system's 4K gaming performance was particularly impressive, often leading or remaining competitive with similarly configured systems from Alienware and Corsair.

Productivity Performance

While the Ryzen 9 9900X3D's 8 cores limited multi-threaded performance compared to competing 24-core processors, the Omen Max 45L still delivered strong results:

• Geekbench 6: 3,253 single-core, 18,394 multi-core
• File Transfer: 2,645.53 MBps (second only to Alienware Area-51)
• Handbrake 4K to 1080p: 2:08 completion time

Software and Features

The Omen Gaming Hub serves as the central control interface, offering:

• Performance profile adjustments
• RGB lighting control
• System monitoring and vitals display
• Game-specific optimizations via Omen AI
• LCD control for the AIO cooler

Additional software includes McAfee Online Protection with VPN and identity monitoring, though the system comes with numerous pre-installed HP utilities that could be consolidated.

Pricing and Configurations

The Omen Max 45L is available in four configurations:

1. Base Model: Ryzen 7 9700X, RX 9070 XT, 32GB RAM, 1TB SSD - $2,544.99
2. RTX 5070 Variant: Same specs with RTX 5070 - $2,534.99
3. X3D Upgrade: Ryzen 7 9800X3D, same specs - $3,254.99
4. Flagship (Reviewed): Ryzen 9 9900X3D, RTX 5090, 64GB RAM, dual 2TB SSDs - $6,499.99

The Bottom Line

The HP Omen Max 45L delivers on its promise of flagship gaming performance, particularly excelling at 4K gaming where its RTX 5090 can stretch its legs. The innovative Cryo Chamber cooling, comprehensive connectivity, and premium build quality justify much of the premium pricing.

However, at $6,499.99, buyers must weigh whether the Omen Max 45L's unique features and performance justify the cost compared to alternatives like the Alienware Area-51, which offers similar performance for slightly less money (though with different cooling approaches and design philosophies).

For gamers seeking the absolute best 4K performance in a distinctive, high-end package with innovative cooling, the Omen Max 45L delivers. But those with more modest needs or tighter budgets will find better value in lower-tier configurations or competing systems.
