Microsoft OMEN HP OMEN 45L Gaming 2025 Review

The HP OMEN 45L with an Intel Ultra 9 and RTX 5090 delivers performance in the 97th percentile. It's a 4K gaming and creative work monster with 64GB of RAM, but it's huge and has very little user feedback. Buy this for top-tier specs, but be wary of the support experience.

The HP OMEN 45L with an Intel Core Ultra 9 285K and an RTX 5090 is a desktop that doesn't just aim for the high end, it lands there. Its CPU and GPU performance sit in the 97th and 93rd percentiles, respectively, which translates to a machine that will laugh at 4K gaming and chew through creative workloads. With 64GB of RAM and a 2TB SSD, it's not just fast, it's also got the muscle to keep a ton of stuff open without breaking a sweat.

Our scores back up the raw specs: a 94.4/100 for gaming and a 91/100 for creator work. This thing is built for pushing pixels and polygons at the highest settings. The trade-off is obvious from the 27.6/100 compactness score and the 22.6kg weight. This isn't a subtle machine; it's a statement piece that needs its own real estate on your desk.

Let's talk numbers. That Intel Core Ultra 9 285K is a 24-core beast hitting 5.7GHz, putting it in the 97th percentile for CPU power. Paired with the RTX 5090's 24GB of VRAM (93rd percentile), you're looking at a rig that will max out any game today and likely for the next few years. In our tests, this combo delivers frame rates that make high-refresh 4K gaming feel effortless.

The 64GB of DDR5 RAM lands in the 98th percentile, which is frankly overkill for pure gaming but a dream for streamers, video editors, or anyone who never closes a browser tab. The 2TB NVMe SSD (91st percentile) ensures load times are a blink. The only performance-adjacent note is the 78th percentile reliability score, which is solid but not exceptional, and the 56th percentile for ports, meaning you might need a hub if you have a lot of peripherals.

Pricing isn't listed, but with an RTX 5090 and 64GB of RAM, we're talking premium territory. The value proposition hinges entirely on how much you need this specific level of top-tier performance. If you're a professional creator or a gamer who demands the absolute best settings, the component quality justifies the cost. However, if your needs are more moderate, competing systems with an RTX 5080 or 64GB of slightly slower RAM might offer a better price-to-performance ratio. Always check current prices against the Dell Alienware Aurora and Lenovo Legion Tower 5i, as vendor deals can shift the value daily.

Stacked against its peers, the OMEN 45L's claim is raw power. The Dell Alienware Aurora R16 might trade blows on GPU but often comes with less RAM at a similar price point. The Lenovo Legion Tower 5i Gen 10 typically offers better value but with last-gen components that can't match the 285K and 5090 combo. The real competition is the MSI MEG Vision X or a custom-built PC. Pre-builts like this OMEN offer convenience and a single warranty, but you pay for that peace of mind. If you're chasing the highest benchmark numbers and want a plug-and-play experience, this HP sits at the top. If budget or tinkering is a bigger concern, the others might win out.

Skip this if you have a small desk, plan to move your PC often, or prioritize proven reliability and stellar customer support. Its 27.6/100 compactness score and 22.6kg weight make it a space hog. The 78th percentile reliability and the negative support feedback in reviews suggest there might be smoother ownership experiences elsewhere, especially if you're not chasing the absolute highest benchmark scores.

This is a data-backed recommendation for a very specific user: someone who wants one of the fastest pre-built gaming desktops available and doesn't care about size, weight, or being an early adopter (hence the low social proof). The performance scores don't lie—it's an elite machine. However, the 16th percentile social proof and mixed support feedback are red flags you can't ignore. We'd recommend this if you find it at a compelling price and are comfortable with HP's support ecosystem. If customer service is a top priority or you want a more proven community around your purchase, look at the more established competitors first.
