HP HyperX OMEN 35L (2026)

HP's product page for the HyperX OMEN 35L is filed under 2026 and presents a 35-litre gaming tower that carries the HyperX name alongside OMEN. The headline is "Dominate the game", and the promise is straightforward: keep temperatures down and fan noise low so nothing pulls you out of the match, built with industry-standard HyperX components, pre-tuned at the factory, with room to upgrade. HP does not publish a price or a launch date on the page I read, so this page carries neither. What it does publish is a specification list that can be compared line by line with the 2025 OMEN 35L, and that comparison is the most useful thing to do with it.

What HP lists

The processor ceiling is the AMD Ryzen 9 9950X3D, which HP gives as 16 cores, 32 threads, up to 5.7GHz maximum boost and 128MB of L3 cache. HP's copy adds that the Ryzen 9000X3D series uses AMD 3D V-Cache technology, with up to 144MB of on-chip memory, and AMD EXPO for higher memory frequencies. Graphics go up to the NVIDIA GeForce RTX 5080 with 16GB of dedicated GDDR7. Memory is up to 64GB of Kingston FURY DDR5-6000 with EXPO and RGB heatsinks, in two 32GB modules. Storage is listed as up to a 2TB PCIe Gen5 NVMe M.2 SSD. Wireless is a Realtek Wi-Fi 7 card with two-by-two antennas and Bluetooth 6.0.

Expansion is one PCIe Gen5 x16 slot, described as Gen5 ready, and one Gen4 x4 slot. The front panel has one USB-C at 10Gbps, two USB-A at 5Gbps with HP Sleep and Charge, and a headphone and microphone combo jack. The rear lists two USB-A ports at 5Gbps, one USB-C at 10Gbps and a second USB-C at 10Gbps with DisplayPort 1.4. The case measures 8.27 by 16.06 by 16.14 inches, or 210 by 408 by 410 millimetres, and weighs 31.97 pounds or 14.5kg, with the usual note that weight varies by configuration. Multiplying the exterior dimensions gives about 35 litres, which fits the name.

Cooling

HP says you can choose how the machine is cooled. The options are an air cooler of up to 120mm with four heatpipes and RGB, or an all-in-one liquid cooler of up to 240mm with either RGB or an LCD screen cap; the radiator fits in one 240mm position. When the air cooler configuration is selected, the case fits up to two 140mm fans. HP describes optimised airflow and fan curves, and it says the goal is a cool and quiet system. There is no noise figure, no temperature test and no comparison to another product on this page, so those statements should be treated as intent rather than measurement. If quiet operation is your main criterion, our quiet PC build guide explains what to look for and why a specification sheet alone cannot tell you.

Power supply

The listed supply is up to 1000W, 80 Plus Gold certified, ATX 3.1 and fully modular. Compared with the 2025 page, which listed 850W or 1000W Gold options and an ATX 3.0 modular unit, this is a newer ATX revision at the top end of the range. It is smaller than the 1200W modular supply that HP's August 2025 launch release said would ship in the latest 35L and the OMEN MAX 45L, so if you want to run the largest graphics card in the OMEN family, look at the OMEN MAX 45L instead.

Design options

Three finishes are listed: Shadow Black Glass with tinted black glass, Ceramic White Glass with tinted black glass, and Shadow Black Stealth Metal. The page explains the styles as White Glass, Black Glass and Stealth. The Stealth Metal option evidently corresponds to the RGB-free look that HP introduced with the 2025 Stealth Edition, although the page does not say so directly. HP states that each unit undergoes end-to-end system-level testing and calibration, and that the ATX industry-standard parts, standard form factors and tool-less access make upgrades quick.

Software

The page promotes OMEN AI, a one-click tool that adjusts operating system, hardware and game settings, and OMEN Gaming Hub for full aRGB control, with custom lighting effects, colours and animations. It also describes swapping in an upgraded fan, liquid cooler or power supply using OMEN Components, which are tested and calibrated to work with the 35L. The page has a section about climbing the ranks in games associated with Riot, which is marketing rather than a technical statement.

Differences from the 2025 OMEN 35L

Setting the two pages side by side shows what changed. The 2026 page lists a 9950X3D processor ceiling where the 2025 page lists an 8700G. Both list an RTX 5080 as the graphics ceiling. Memory is 2 by 32GB at 6000 MT/s rather than 4 by 16GB at 5200 MT/s. Storage is a Gen5 drive rather than Gen4, and the page does not list a hard drive. Wireless moves from a MediaTek Wi-Fi 7 card with Bluetooth 5.4 to a Realtek Wi-Fi 7 card with Bluetooth 6.0. The power supply moves to ATX 3.1. There are three colour options rather than four, and the case volume, dimensions and weight are identical. Our side-by-side comparison shows these differences in one table. These are differences between two product pages, not between two tested machines, and the pages may not list every available configuration.

Wording that needs care

Two details on the page look like carry-over copy. First, the section on RTX 50 series graphics refers to "GeForce RTX 50 Series Laptop GPUs" even though this is a desktop, which looks like text reused from a laptop page. The specification list, which names a desktop-class RTX 5080, should take precedence. Second, the page uses the phrase "HyperX Components" in the headline copy and "OMEN Components" in the upgrade paragraph, and does not explain how the two labels relate. I have not seen HP's own explanation of this, so I use the specification list as written and avoid guessing.

Who it suits

If you want a mid-size prebuilt with a Gen5 SSD, the newest wireless standards on this page and the option of a 240mm liquid cooler, this is the more current of the two 35L pages. If you value a larger drive setup with a spinning disk or a lower entry price, the 2025 page lists a hard drive option and a published 1,499.99 dollar starting price. For upgrade planning in general, our guide to which components age best in a PC applies directly to a tower with a Gen5-ready graphics slot and modular power supply. High refresh rates are the usual reason to buy this class of GPU, and our refresh rate guide explains when 240Hz and above are worth paying for.
