Built for extreme performance, the OMEN by HP 45L Gaming Desktop PC is designed for gaming from the ground up. Powered by the latest AMD processor[1], the OMEN by HP gaming desktop takes cooling to incredible heights with a unique cooling chamber. Created for easy tool-less upgradeability with industry standard components to meet your gaming needs.

OMEN Cryo Chamber™

Enables the liquid cooler radiator to pull-in cold air from the surrounding environment to cool down the CPU.

Crafted for expansion

Easily upgrade and expand the memory, storage drives, and interior expansion slots to fit your gaming needs.

OMEN Gaming Hub

Get a fresh perspective

Windows 11 provides a calm and creative space where you can pursue your passions through a fresh experience. From a rejuvenated Start menu, to new ways to connect to your favorite people, news, games, and content—Windows 11 is the place to think, express, and create in a natural way.[2]

AMD Ryzen™ 5000 Series Desktop Processor

Whether you are playing the latest games, designing the next skyscraper, or crunching scientific data, you need a powerful processor that can handle it all—and more. Hands down, the AMD Ryzen™ 5000 Series desktop processors set the bar for gamers and artists alike.[1]

The Ultimate Play

The GeForce RTX™ 3070 is powered by Ampere—NVIDIA’s 2nd gen RTX architecture. Built with enhanced RT Cores and Tensor Cores, new streaming multiprocessors, and high-speed G6 memory, it gives you the power you need to rip through the most demanding games.[3]

Ethernet port

When you have a spotty wireless connection, you can quickly plug in your Ethernet cable to get a smooth, wired Internet experience that bypasses any wireless issue.

Dual channel memory

With dual channel technology, two channels work simultaneously to double the communication speed between the memory controller and the RAM increasing system performance.

Dual storage configurations

By including both an SSD drive for the operating system and a traditional hard drive you get the benefits of both worlds—fast boot up times, snappy responsiveness, and larger storage capacity.

Sustainable design

Because little things make a big difference, this product includes sustainable materials like water-based paint in the design.[4]

McAfee® LiveSafe™

Protect your operating system with a free 30-day McAfee® LiveSafe™ subscription.[5]

Show off your hardware

Rated 1 out of 5 by Hannibal2024 from Terrible customer service buy local. Purchase this computer 6 months ago. The graphics card went bad recently and I tried to work with customer service to get this repaired. Their solution is to send the product in for repair which is about a month. I tried to get this expedited but HPs only option is to send it in for repair which takes about a month. I work from home I can't afford to have a computer away from me for a month but I had no other option that's terrible customer service if you asked me.

Rated 4 out of 5 by Muhtasim from OMEN 45 The PC works great. It runs extremely fast when playing high-end like Elden Ring and Cyberpunk 2077. The hp/omen support is one of the best in the industry. The only issue I had was with shipping and a slight dent on the back of the PC, nothing substantial/noticeable but it is slightly annoying .

Rated 1 out of 5 by DontbuyOmen from PC completely shuts down after 1 hour playing battlefield 2042 at 1080p 60hz PC completely shuts down after 1 hour playing battlefield 2042 at 1080p 60hz (only playing at this resolution until I get a new PC). The only way to turn the PC back on is by unplugging it and plugging it back in. Also the PC arrived with one of the case fans not working, I mean come on, this PC cost more than my first car and it arrived in this condition?
