Core i9 9900 8(9) 3.1 GHz 5.0 GHz

Memory

Alienware Area 51 R2 has four RAM slots and supports dual channel memory configuration. This is sufficient for almost any use case and especially in situations where the workload calls for more RAM.

To cover the needs of your OS, games, and apps, Alienware Area 51 R2 supports up to 64 GB of DIMM DDR4-2133/2667 RAM. For office work, home use, and light gaming we recommend 8GB of RAM. For everything else, use 16GB or more.

Faster RAM speeds permit your processor to access the data stored inside the memory faster. This is important for the overall speed of your system. The motherboard of the Alienware Area 51 R2 supports RAM speeds of up to 2667 MT/s.

Wi-Fi Support

Alienware Area 51 R2 comes equipped with an on-board M.2 2230 (WiFi/BT) slot. This slot is used for a Wi-Fi and Bluetooth combo card.

Ports

Ports are important and often people don't think about them when buying a PC. For example, if you don't have enough USB ports, using external devices becomes problematic. Before you buy any system, considering your use case, check the number of external devices you are going to use and plan the number of the extension ports accordingly.

USB ports

The Alienware Area 51 R2 comes with ten USB ports in total. Having more USB ports is always better, but also pay attention to the version of those USB ports. Higher version ports support faster transfer speeds. Unfortunately, this model doesn't come with a USB 3.1 port. If you need a faster connection for your peripherals, like external Solid State Drive, you will need to choose another model.

Video ports

The DisplayPort (DP) is now the most widely used digital interface for transmitting digital video and audio between display devices and PCs. It is unfortunate to see that the Alienware Area 51 R2 doesn't have one. Check out the HDMI section and make sure that you are at least getting an HDMI port - a good substitution for the DP.

The HDMI port is another digital video port you can use to connect external display. It has very similar capabilities to the DisplayPort with few exceptions. However, the Alienware Area 51 R2 doesn't have one. This is not a problem if there is on-board DisplayPort.

*Please keep in mind in order to use the video ports available through the motherboard, you need a CPU with integrated graphics card. If you have a dedicated GPU, use his ports instead.

SSD storage - M.2 sockets and SATA ports

The SATA port is one of the places where you can connect a stora gedevice. The Alienware Area 51 R2 comes with six SATA port(s). Not enough SATA ports might limit your options for additional storage devices. Think about your use case and decide if the SATA ports provided by this model will be sufficient.

Unfortunately, the Alienware Area 51 R2 has no M.2 PCIe soket and you have to rely on the available SATA ports to connect your drives.

The M.2 PCIe SSD connector in combination with an NVMe drive allows for higher transfer rates, compared to the old SATA interface. In some situations, NVMe device connected to the M.2 PCIe socket can be more than 5 times faster.

Power Supply

The Alienware Area 51 R2 comes with a 1500 Watt PSU. Having a power supply with high power rating is important, especially if you are doing upgrade with addtional components, like dedicated GPU and more HDDs. Will this 1500 W be enough, it all depends on your specific use. Please keep in mind that some models might have more than one PSU option. Whenever possible get the most powerful one, as it might make future upgrades easier.
