HP Omen HP Omen 45L RTX 5080 Gaming Desktop, Intel Ultra 9 Review
The HP Omen 45L packs an RTX 5080 and Intel Ultra 9 for brutal 4K performance. It's fantastic, but you'll need a big desk for this gaming PC powerhouse.
The 30-Second Version
The HP Omen 45L RTX 5080 is a beast. It delivers top-tier performance for 4K gaming and heavy creative tasks, scoring in the 90+ percentile for key specs. Worth buying if you find it near the $2850 mark and have the space for its massive tower.
Overview
The HP Omen 45L with the RTX 5080 and Intel Ultra 9 285K is a monster of a gaming PC. It's built to crush 4K gaming and heavy creative work without breaking a sweat. The specs are top-tier, from the 64GB of DDR5 RAM to the massive 8TB of combined storage. It's not subtle, and it's definitely not small, but it's built to dominate.
HP throws in a Thunderobot gaming keyboard, which is a nice bonus, but let's be real: you're here for the raw power inside that massive case. This is a system for people who want to max out every setting and not think about upgrades for years.
Performance
This thing is fast. The Intel Ultra 9 285K lands in the 97th percentile for CPU performance, and it shows. It chews through video encodes and complex game logic. The RTX 5080 is no slouch either, sitting in the 91st percentile. It'll handle 4K gaming at high refresh rates with ease. The only real performance 'weakness' is that it's a massive tower, scoring a 32.7 for compactness. You need the desk space for it. But that size helps with cooling, keeping those powerful components from throttling.

Value & Pricing
Pricing is all over the place, from about $2850 to $3670 depending on the vendor and exact specs. At the lower end of that range, it's a compelling deal for this level of hardware. At the high end, you're paying a premium for the Omen branding and that specific configuration. Shop around. The value is in the raw, no-compromise performance. If you need this much power, it's priced competitively with similar builds from Alienware or MSI.
vs Competition
Stacked against the competition, the Omen 45L's big advantage is its cooling design and straightforward power. The Dell Alienware Aurora often has a more unique look but can be trickier to upgrade. The MSI MEG Vision X might have more flashy AI features, but the Omen is a pure performance workhorse. Compared to something like a Lenovo Legion Tower, the Omen generally has a slight edge in high-end config availability and that massive case for airflow. It's a toss-up between this and the MSI for raw specs, but the Omen feels more purpose-built for just being fast.

Common Questions
Q: Can this PC run 4K games at high frame rates?
Absolutely. The RTX 5080 and Ultra 9 CPU are built for it. You'll max out settings in most current titles and get high refresh rates.
Q: Is the 64GB of RAM overkill for gaming?
For pure gaming today, yes. But for future-proofing or if you stream, edit video, or run VMs alongside your games, it's fantastic and eliminates bottlenecks.
Q: How is the upgradeability?
Very good. The 45L case has plenty of room and standard components, making it easy to swap out the GPU, add more storage, or upgrade the RAM later on.
Who Should Skip This
If you have a tiny desk, live in a small apartment, or ever plan to move your PC, look elsewhere. This thing is a 50-pound behemoth. Also, if you're on a tight budget and only play at 1080p, this is massive overkill. A cheaper system with an RTX 5070 or 5060 would serve you just as well.
Verdict
Buy this if you're a serious gamer or content creator who wants a pre-built system that can handle absolutely anything for the next several years. You need the desk real estate and you don't want to fuss with building it yourself. It's a set-it-and-forget-it power solution.
