Can you upgrade Dell XPS 8900 to play games?

Yes, Dell XPS 8900 is a home and gaming machine pre-assembled with dictated graphics card. You can easily play games and upgrade it with better hardware components. Processors, memory modules, and storage devices are easy to install. However, these PCs sometime have proprietary elements like the power supply unit, the chassis or the power connector, which can make it difficult for users to install aftermarket PSUs to support better GPUs.

Please explore the sections bellow to find ideas and suggestions on how to upgrade Dell XPS 8900.

Windows 11 compatibility

No, Dell XPS 8900 does not meet the Windows 11 hardware requirements. According to Windows 11 specification, all models with Intel 7th Gen CPU or older are not officially supported. Processor with TPM 2.0 and a UEFI Secure boot BIOS is also required in order to upgrade from Windows 10 to Windows 11 through Windows Update.

However, anyone with PC that does not pass the upgrade test can download the official Windows 11 ISO, make a bootable flash drive, and install the OS manually.

GPU upgrade

Dell XPS 8900 is a gaming computer and comes assembled with a dedicated graphics card. According to the specification the best possible GPU you can use with it is GeForce GTX 1080 Ti. You can upgrade Dell XPS 8900 graphics card, but you should select a model that requires 460 W or less.

GPU upgrade options for Dell XPS 8900 with the stock 460W power supply:

GPU Power consumption Memory Req.
AMD RX 6600 160 W 8 GB DDR6 *Dual SATA to PCIe adapter
NVIDIA RTX 2060 170 W 6 GB DDR6 *Dual SATA to PCIe adapter
AMD RX 6600 XT 165 W 8 GB DDR6 *Dual SATA to PCIe adapter
NVIDIA RTX 2070 175 W 8 GB DDR6 *Dual SATA to PCIe adapter
NVIDIA RTX 3060 170 W 8 GB DDR6 *Dual SATA to PCIe adapter
NVIDIA RTX 2070 Super 215 W 8 GB DDR6 *Dual SATA to PCIe adapter
NVIDIA RTX 2080 220 W 8 GB DDR6 *Dual SATA to PCIe adapter
* Typically, the stock power supply in a OEM gaming PCs have the necessary 6 or 8 pin connectors and you don't need any adapters to power the GPU. However, if this is not the case, you may need to use a low-power GPU or a SATA to PCIe power adapter. Alternatively, you can change the entire PSU.

Please note that upgrading to a more power-hungry GPU requires a better PSU. However, in most cases, this may not be possible because most OEM pre-built PCs have motherboards that use a proprietary power connector. Nevertheless, this problem can be solved by using a power adapter. The more challenging problem arises when the model has a non-standard chassis or power supply, in which case upgrading the PSU becomes much harder.

Processor

The Dell XPS 8900 supports Gen6 Intel Core technology. Intel introduced the 6th generation of its Core CPUs in August 2015. Named Skylake, it uses the same 14nm manufacturing process like the old 5th gen. The improvements are better CPU and GPU performance and reduced power consumption. Other enhancements include Thunderbolt 3.0 and SATA Express.

Best CPUs for Dell XPS 8900 upgrade:

Model Cores (Threads) Base frequency Turbo
Core i5 6500 4(4) 3.2 GHz 3.6 GHz
Core i5 6600 4(4) 3.3 GHz 3.9 GHz
Core i7 6700 4(8) 3.4 GHz 4.0 GHz

Memory

Dell XPS 8900 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, Dell XPS 8900 supports up to 64 GB of DIMM DDR4-2133/2400 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 Dell XPS 8900 supports RAM speeds of up to 2133 MT/s.

Wi-Fi Support

Dell XPS 8900 supports Wi-Fi and Bluetooth combo card with the on-board M.2 2230 (Wi-Fi/BT) slot. The card contains a Wi-Fi module that supports various Wi-Fi standards, as well as a Bluetooth module. It is small circuit board that is designed to fit into a dedicated slot on the motherboard.

Keep in mind that the card is not always included and you have to install one yourself.

Wi-Fi and Bluetooth wireless adapter upgrades for Dell XPS 8900:

Model Speed Frequency Interface
WiFi 6E (Gig+) Kit 3000 Mbit/s 2.4GHz / 5GHz NGFF M.2 A/E Key
Rekong AX210 3000 Mbit/s 2.4GHz / 5GHz NGFF M.2 A/E Key

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 Dell XPS 8900 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 the most widely used digital interface for transmitting digital video and audio between display devices and PCs. It is good to see that the Dell XPS 8900 is featuring a DisplayPort 1.4. The post version is important if you target higher resolutions with high refresh rate. Although, ver. 1.2 is completely fine for most users, if possible, aim for the higher versions DisplayPort.

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. Dell XPS 8900 comes with one HDMI 1.2 port(s) on the motherboard. In case your monitor supports another interface, you can always use an adapter.

*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 Dell XPS 8900 comes with five 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 Dell XPS 8900 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 Dell XPS 8900 comes with a 460 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 460 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.
