HP OMEN 35L (2025)

The OMEN 35L is HP's mid-size gaming tower, and the 2025 refresh is the version this page covers. HP announced two refreshed OMEN 35L desktops on 14 August 2025 at its Level Reforge event in Los Angeles, alongside the larger OMEN MAX 45L. The regular 35L and a Stealth Edition were both expected on HP.com in October 2025 with a starting price of 1,499.99 dollars. HP's product page calls the 35L its first PC built with OMEN Components, meaning fans, liquid coolers and power supplies that HP designs and tests itself rather than buying as anonymous parts. This page separates what HP's launch release says from what the product page lists, because the two describe noticeably different ceilings.

Two descriptions of the same desktop

The launch release says the latest OMEN 35L supports up to an AMD Ryzen 9 9950X3D and NVIDIA GeForce RTX 5090 graphics, with improved thermal performance and the same modular 1200W power supply that debuted in the OMEN MAX 45L. The product page for the AMD and NVIDIA version, by contrast, lists up to an AMD Ryzen 7 8700G, up to an NVIDIA GeForce RTX 5080 with 16GB of GDDR7, and a power supply of 850W or 1000W rated 80 Plus Gold. The page's own headline banner names the RTX 5000 series and a powerful Ryzen processor without specifying the model.

The simplest explanation is that they describe different configurations of the same chassis. HP sells the 35L under several product pages, and our other page for the HyperX OMEN 35L lists a Ryzen 9 9950X3D, an RTX 5080 and a 1000W ATX 3.1 supply. HP does not say on the pages I read which of the many configurations carries the 9950X3D and RTX 5090 mentioned in August 2025. If you want that top build, confirm it on the configurator before ordering. If you are buying the version described by the product page, expect the 8700G and RTX 5080 ceiling.

Component list from HP's product page

The processor ceiling is the Ryzen 7 8700G, which HP describes as reaching 5.1GHz with 16MB of L3 cache, 8 cores and 16 threads. Graphics go up to the RTX 5080 with 16GB of GDDR7, based on NVIDIA's Blackwell architecture and supporting DLSS 4. Memory is listed as up to 64GB of Kingston FURY DDR5-5200 with EXPO profiles and RGB heatsinks, in four 16GB modules. Storage is up to two 2TB PCIe Gen4 NVMe drives plus one 2TB 7200rpm hard drive. Wireless is a MediaTek MT7925 Wi-Fi 7 card with Bluetooth 5.4, and there is a PCIe Gen5 x16 slot described as Gen5 ready. HP says the case takes graphics cards up to 335mm and power supplies up to 160mm.

If you are thinking about how much memory to specify, our guide to how much RAM you need covers typical workloads, and our storage guide comparing SATA SSD, NVMe SSD and HDD explains why the mixed NVMe and hard drive layout HP lists is a sensible arrangement for a game library.

Cooling and noise

HP gives more detail on cooling than on almost anything else. The case supports a 120mm four-heatpipe RGB air cooler or up to a 240mm liquid cooler, which can be ordered with an LCD screen cap. When liquid cooling is selected, HP says the pump is an Asetek seventh-generation unit. There is a 120mm exhaust fan at the rear, and a 135mm fan that supports zero-RPM operation, with HP quoting a noise rating of Cybernetics A-. HP also says custom preloaded fan curves keep the machine cooler and quieter, and that the thermal performance is 10 to 14 percent better than the older OMEN 25L and 40L depending on configuration. That is an internal comparison against HP's own earlier products and HP does not publish the test method on the page. For a general discussion of noise and how to read fan specifications, see our quiet PC build guide.

Fan speed and lighting are managed in OMEN Gaming Hub. HP also lists a Booster feature that it says can raise frame rates by up to 10 percent, a universal game launcher covering locally owned and cloud games including more than 100 free-to-play titles, and RGB control at 16.8 million colours. These are software features and manufacturer claims; the 10 percent figure will depend heavily on the game and the machine.

Chassis, size and sustainability

The case dimensions are 8.27 by 16.06 by 16.14 inches, which multiplies out to roughly 35 litres and matches the name. HP lists the weight as 31.97 pounds, about 14.5kg, and says it varies with configuration. The board is a 244 by 244mm micro-ATX design. Access is completely tool-free, and there are removable mesh dust filters on the front fan and the bottom power supply position. HP says every case uses recycled plastic, recycled metal and sustainable paint. Four design options are listed: black with a perforated mesh front panel and rounded bezel, black with a glass front and square bezel, white and black with a mesh front and square bezel, and white with a perforated mesh front and rounded bezel.

The Stealth Edition, mentioned in the launch release, has the same internals as the standard 35L in an all-black, RGB-free design. HP says it is the official PC of League of Legends Esports and the VALORANT Champions Tour, and that it is built to the specifications used by professional players. That is a partnership statement rather than a performance claim.

Ports

The front panel lists one USB-C port at 5Gbps with HP Sleep and Charge, two USB-A ports at 5Gbps and one USB-C port at 10Gbps. HP's page does not list Thunderbolt, and it does not give the full rear port list in the text I read, so check the configurator if you need specific rear connections.

How it compares with the rest of the OMEN range

The 35L sits below the larger OMEN MAX 45L, which is HP's flagship with a separate cooling chamber for the radiator and a 360mm cooler. The 35L keeps the radiator inside the case and tops out at 240mm. It is smaller, lighter and starts at a price HP has published, while the flagship's price was not announced in the material I read. If you are choosing within the 35L family, our OMEN 35L versus HyperX OMEN 35L comparison puts the two side by side, including the differences in Wi-Fi, storage and power supply.

Who it suits

The 35L is a good match for someone who wants a prebuilt desktop with standard parts, tool-free upgrades and a moderate footprint, and who values having a single company responsible for testing the fans, cooler and power supply together. It is less compelling if you want the biggest possible graphics card or a top-end processor, given the ceilings on this particular product page. It is also worth remembering that an 850W or 1000W supply leaves less headroom than the flagship's 1200W unit for future graphics card upgrades, although HP does not state a specific upgrade limit.

Reading the price

The 1,499.99 dollar starting price comes from the launch release and applies to the entry configuration at launch. I have not seen how HP prices the higher configurations, and the price you pay will vary with the configuration and any promotions. Use it as a floor rather than a typical price.
