Everything you need to know
Design & Build
The Omen Max 45L is a big tower: HP lists 8.03 × 18.5 × 21.85 inches and 49.82 lb. The black case has a glass front and side panel, three RGB intake fans behind a removable dust filter and a separate compartment on top for the CPU radiator. Both Tom's Hardware and Windows Central like the tool-free access – press a button and the side panels swing open.
Windows Central is less happy with the assembly of its unit: cable management was messy on both sides, and a few panels did not sit perfectly flush.
Takeaway: A striking, easy-to-open case; the inside could be tidier.
Performance
This configuration combines the Ryzen 7 9800X3D with an RTX 5080 and 32 GB of DDR5-6000. Windows Central tested HP's custom RTX 5080 (with a Ryzen 9 9950X3D) and found it performing exactly as expected, with 8,996 points in 3DMark Speed Way. For buyers who mainly play games, the reviewer recommends the 9800X3D configuration over the pricier 16-core chip.
Tom's Hardware's RTX 5090 unit led most of its 1080p benchmarks and showed that the chassis lets high-end parts run at full speed.
Takeaway: Top-tier 1440p and strong 4K gaming. Check the current price on Amazon (opens Amazon in a new tab)
Cooling & Noise
HP's Cryo Chamber places the 360 mm CPU radiator in its own compartment that only breathes outside air, so the hot GPU air does not reach it. Windows Central measured 46 °C on the CPU and 75 °C on the GPU during a long 3DMark stress test, and at most 47 dB – quieter than most prebuilt PCs it has tested. Tom's Hardware heard only a low hum under load.
Takeaway: Very quiet for this much power.
Upgradability & Features
HP lists four DIMM slots, two M.2 SSD slots, one PCIe Gen5 x16 and one PCIe Gen4 x4 slot, Wi-Fi 7 and 2.5 Gb Ethernet; the case also fits full-size ATX boards and has room for hard drives. To reach the second SSD slot you have to remove the graphics card. The fully modular power supply can be swapped later. On the software side, expect several HP apps, McAfee and ads in the Omen Gaming Hub, according to Windows Central.
Takeaway: Easy to extend; clean up the preinstalled software once.
Value for Money
The Omen Max 45L is not cheap, and Windows Central notes that a DIY build with similar parts would cost less. In return you get excellent cooling, very low noise and a chassis built for future upgrades.
Takeaway: For gamers who value quiet high-end performance over a tidy interior. See it on Amazon (opens Amazon in a new tab)

How fast is the RTX 5080 in this PC?
Windows Central found HP's custom RTX 5080 performing exactly as expected (8,996 points in 3DMark Speed Way). Tom's Hardware's RTX 5090 unit shows what the chassis can handle: no thermal limits and only a low hum under load.
Why the Ryzen 7 9800X3D?
For gaming it is the sensible choice: Windows Central recommends it over the pricier Ryzen 9 9950X3D if you buy this PC mainly to play games.
What is the Cryo Chamber?
The CPU's 360 mm radiator sits in a separate compartment at the top of the case and only breathes outside air. HP claims up to 7 °C lower CPU temperatures; Windows Central measured 46 °C on the CPU during a long 3DMark stress test.
Can I upgrade it?
Yes. HP lists four DIMM slots, two M.2 SSD slots, one PCIe Gen5 x16 and one PCIe Gen4 x4 slot, and the case fits full ATX boards. Reaching the second SSD slot means removing the graphics card, both reviewers note.
How big is it?
HP lists 8.03 × 18.5 × 21.85 inches (W × D × H) and 49.82 lb. Windows Central notes the top compartment doubles as a carrying handle.
What warranty does it have?
HP lists a 1-year limited hardware warranty.
Verdict: HP Omen Max 45L
A big, very quiet RTX 5080 tower with a separate CPU cooling chamber – top-tier 1440p and 4K gaming.
