Ready-to-game desktop for high-end 4K and VR

The HP OMEN MAX 45L tower ships with Windows 11 Pro installed and a 1200W power supply. It targets enthusiasts who want a pre-built system capable of 4K gaming and VR workloads without assembling parts themselves. Buyers who prefer to choose every component or need a smaller chassis should look elsewhere.

Graphics card with 32GB GDDR7 memory

The GeForce RTX 5090 provides 32GB of GDDR7 video memory and a dedicated GPU architecture. That VRAM capacity is the single figure that determines whether the system can hold the largest textures and models in memory at 4K or in VR. If your workflow needs more video memory than 32GB, this configuration will not meet it.

Pre-assembled with 360mm liquid cooling

The tower arrives fully built with a 360mm AIO cooler, RGB fans and a 1200W PSU already installed. The 18.5 by 22 by 8 inch case requires adequate desk or floor space and airflow clearance. The included Dockztorm USB hub adds extra ports, but the system has no internal drive bays for additional 3.5 inch hard drives.

Questions about this item

How does the 128 MB L3 cache on the Ryzen 9 9900X3D affect gaming performance?

The large 128 MB L3 cache reduces latency by keeping more game data close to the 12 cores, helping sustain high frame rates at 4.4 GHz base and up to 5.5 GHz boost clocks.

What bandwidth ceiling does the PCIe interface impose on the RTX 5090 in this system?

The RTX 5090 32 GB GDDR7 card runs on the platform's PCIe lanes; its 32 GB frame buffer and memory speed determine throughput for 4K and VR workloads.

Will the 360 mm AIO and 1200 W PSU fit in a standard mid-tower case?

This tower chassis measures 18.5 x 22 x 8 in and weighs 45.5 lb, so it requires a full-tower or oversized mid-tower with 360 mm radiator clearance and room for the 1200 W unit.
