Pro-level gaming
You know X51. You’ve seen it at eSports tournaments and events. The stakes are high and the new X51 will make you better equipped to compete. But you don’t have to be front and center at a tournament to experience the size and performance of X51. Now you can play like the pros – straight from your home base.

Choose cutting-edge liquid cooling
Add some edge to your game with optional Alienware SFF Advanced Liquid Cooling to enable CPU overclocking, a first for X51. Expect incredibly quiet, but powerful performance when you need it most. A low profile and compact blower design pushes heat outside the rear of the chassis, and a copper cold plate ensures efficient heat transfer. Plus, all units are 100% leak and weight tested to meet quality requirements.

Get into 4k gaming
Turbocharge your gaming with the optional Alienware Graphics Amplifier. With advanced NVIDIA® or AMD-enabled graphics, you can enable support for Ultra HD 4K gaming for immersive 3840x2160 resolution. That’s four times the resolution of 1080p.

When you add the graphics amplifier to the compact X51, you’ll have more options when it comes to arranging your desk. You don’t need much space, so you can place this duo where you want it.

Even without the amplifier, X51 delivers exceptional gaming performance at 1080p and supports up to an NVIDIA® GeForce® GTX 960 graphics card. The amp is also compatible with Alienware laptops.

Overclocked performance
The new X51 is outfitted with quad-core 6th Gen Intel® Core™ processors and features unlocked K-series processors that enable additional overclocking features so they can be tweaked to boost performance. Our highest-end processor will deliver an overclock of up to 4.4GHz.

With Turbo Boost Technology, your processor runs faster when you need it to and Hyper-Threading Technology doubles your CPU cores increasing performance on multi-threaded tasks so you can run resource hungry programs more smoothly. The X51’s entire engine has been overhauled since the last generation, now built on a chipset foundation that’s based on the Intel Z170 Chipset and the latest DDR4 memory
 

Fast PCIe SSDs and substantial storage.

We’ve added more storage options without sacrificing performance or increasing X51’s size so there’s plenty of room to archive games, tunes and more. The new X51 supports M.2 PCIe SSDs with a connector positioned alongside the frame that holds the graphics card. Though the drive is positioned on the assembly holding the GPU, it has its own dedicated data connection, eliminating performance sharing or loss. And you never have to worry about electrical interference.

And with PCIe SSDs, all those games, tunes and other media you love will load way faster with up to 4GB/s of total bandwidth

Quick connections
Alienware wants to ensure that you win, and with 802.11ac2x2 WiFi, you can connect quickly to download faster, stream easily, and enjoy smoother overall gaming. X51 also includes a Gigabit Ethernet port for maximum networking performance.

Ports for all your peripherals
Manage all your peripherals with more freedom thanks to a built-in USB hub, where everything’s connected to one, main unit. X51 has 8 total USB ports: 2x SuperSpeed USB in the front, 2x each on the back, a Hi-Speed USB, SuperSpeed USB, and SuperSpeed USB 10 Gbps.

Besides the chassis, your processors, graphics card, memory, wireless controller and hard drives are all upgradeable to support future expansion. Plus, you can maximize your space with dual orientation for vertical or horizontal configuration.
