Pros & Cons
Pros
- RTX 5090 with 32GB VRAM handles 4K gaming and AI workloads with ease 100th
- 128GB DDR5 RAM is overkill in the best way for heavy multitasking 98th
- 4TB NVMe SSD gives you tons of fast storage 98th
- Excellent port selection including 40Gbps USB-C and triple DisplayPort 97th
Cons
- Massive and heavy at nearly 26kg
- Price tag around $10,000 puts it out of reach for most buyers
- Compactness score of 29 means it eats up a lot of space
- No customer reviews yet, so real-world reliability is unproven
The proof
Performance
The specs here are basically a flex. The Core Ultra 9 285K sits in the 97th percentile for CPUs in our database, and the RTX 5090 is one of the best GPUs on the market right now. 128GB of DDR5 RAM and 4TB of NVMe storage both land in the 99th percentile, so multitasking and file transfers are going to feel instant. Port selection is also excellent, with a 40Gbps USB-C, three DisplayPorts, and plenty of USB-A. The one weak spot is compactness, which scores a 29 out of 100. This is a big tower, and it takes up real desk or floor space.

vs Competition
Compared to the Lenovo Legion Tower 5a Gen 10, the OMEN 45L has a clear edge in raw specs, especially with the RTX 5090 and 128GB of RAM. The Apple Mac Studio M3 Ultra is a different beast entirely, better for Mac-centric creative workflows but not a direct gaming competitor. The Dell Area-51 and CLX builds offer similar high-end configurations, but the OMEN's port selection and storage capacity give it a slight edge. The ASUS ROG GM700 is another strong contender, though the OMEN's CPU and RAM combo puts it ahead for AI and developer tasks.

Price
Value & Pricing
At around $10,049 USD, this is not a value play. You're paying a premium for top-shelf components and the convenience of a prebuilt system. If you need this level of performance for AI work, 3D rendering, or 4K gaming and don't want to build it yourself, the price is what it is. But if you're just looking for a solid gaming rig, you can get 90% of the experience for half the money elsewhere.

Overview
The HP OMEN 45L is an absolute monster of a desktop. Intel's Core Ultra 9 285K with 24 cores, an RTX 5090 with 32GB of VRAM, 128GB of DDR5, and a 4TB NVMe SSD. This thing is built to crush AI workloads, 4K gaming, and heavy creative projects without breaking a sweat.
It's also huge and heavy. At nearly 26kg, you're not moving this around casually. And with a price tag around ten grand, this is a serious investment for people who need top-tier performance right now, not a casual upgrade.
Common Questions
Q: Is the HP OMEN 45L good for AI and machine learning?
Yes. The RTX 5090 with 32GB of VRAM and 128GB of system RAM make it excellent for running large models and AI workloads. Our database scores it 94.2 out of 100 for AI and LLM tasks.
Q: Can this handle 4K gaming at high settings?
Absolutely. The RTX 5090 is one of the most powerful GPUs available, and with 32GB of VRAM, it handles 4K gaming at high refresh rates without breaking a sweat.
Q: How much space does the OMEN 45L take up?
It's a full mid-tower and weighs nearly 26kg. Compactness is its weakest area, scoring just 29 out of 100, so make sure you have room for it.
Who Should Skip This
Skip this if you're a casual gamer or just need a PC for everyday tasks. You don't need a $10,000 machine to browse the web, run Office, or play esports titles. If you want a smaller footprint, look elsewhere, because this tower is massive and heavy. And if you're on any kind of budget, there are far cheaper prebuilts that will handle 1440p gaming just fine.
Verdict
This is for people who need maximum performance and don't want to mess with building a PC. AI researchers, 3D artists, video editors working with 8K footage, and gamers who want 4K at high refresh rates without compromise. If that's you, the OMEN 45L delivers. If you're a casual gamer or just need a solid work PC, this is way more machine than you need.
