Dell XPS 8900
Specification and Upgrade Options
The Dell XPS 8900 is a scalable home and gaming desktop designed for heavy office workloads, content creation, and home flexibility. First released in 2015, it is built on the Z170 chipset and supports 6th gen Intel Core processors and up to 64GB of DIMM DDR4-2133/2400 memory. Thanks to its larger chassis, it accommodates dedicated graphics cards, making it an excellent candidate for a gaming PC conversion or a high-performance workstation.
If you are looking for a system with maximum upgradability, Dell XPS 8900 is a good option. Models in this category usually have 4x PCIe slots, several drive bays and better cooling.
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.
Does Dell XPS 8900 support Windows 11?
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.
Processor
The Dell XPS 8900 supports Gen6 Intel Core technology on a Z170 chipset. 6th generation Intel Core CPUs (Skylake) represent a more modern baseline for productivity and development workloads. Lower-end CPUs are suitable for office use and programming, while higher-end i7 models can handle home lab setups, multiple virtual machines, and more demanding emulation. Gaming performance is acceptable with appropriate GPUs, though modern titles may expose CPU limitations.
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 |
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 |
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.
Memory
Dell XPS 8900 supports up to 64 GB of DIMM DDR4-2133/2400 RAM across four DIMM slots, with memory speeds up to 2133 MT/s and dual-channel support depending on the installed configuration.
Actual supported memory capacity and memory channels may vary depending on the installed CPU and chipset.
Typical Dell XPS 8900 memory configurations include 8 GB for everyday productivity and 16 GB for gaming, heavier multitasking, or professional workloads.
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 |
| Gigabyte GC-Wbax200 | 2400 Mbit/s | 2.4GHz / 5GHz | PCIe |
| TP-Link Archer TX50E | 2400 Mbit/s | 2.4GHz / 5GHz | PCIe |
| TP-Link Archer T9UH | 1300 Mbit/s | 2.4GHz / 5GHz | USB 3.0 |
Ports
Dell XPS 8900 provides a fixed set of external I/O ports for connecting peripherals and displays. Port availability and versions determine supported data transfer speeds and display capabilities.
USB ports
Dell XPS 8900 includes ten USB ports in total in the following configuration - (4x) USB-A 2.0; (6x) USB 3.0; with no USB 3.1 ports available.
Video ports
Dell XPS 8900 features one DisplayPort 1.4 output, suitable for modern digital displays.
HDMI output is provided via one HDMI 1.2 port.
Motherboard video outputs require a CPU with integrated graphics. Systems equipped with a dedicated GPU must use the video ports on the graphics card instead.
SSD storage - M.2 sockets and SATA ports
The Dell XPS 8900 comes with five SATA port(s) for connecting storage devices.
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.
*Keep in mind that some M.2 connectors may not support SATA SSDs. Check the motherboard manual to confirm compatibility.
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.
