Lenovo ThinkCentre M800 Small

Specification and Upgrade Options

The Lenovo ThinkCentre M800 Small is a pre-built business desktop computer first released in 2015. Although more than five years old, it is still a viable solution for home and office. The motherboard is using the Q150 chipset and supports 6th gen Intel Core processor, 64GB of DIMM DDR4-2133 memory. You can even turn this PC into a gaming machine with a proper GPU upgrade.

Lenovo ThinkCentre M800 Small is a Desktop form factor computer. The Desktop form factor, just like the Tower, comes with 4x PCIe slots but low profile ones. Often manufacturers will use the same motherboard as the Mini Tower model. Usually Desktop form factor PC will have the same height as a Tower but with a lower profile.

Windows 11 compatibility

No, Lenovo ThinkCentre M800 Small 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 Lenovo ThinkCentre M800 Small 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.

Memory

Lenovo ThinkCentre M800 Small 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, Lenovo ThinkCentre M800 Small supports up to 64 GB of DIMM DDR4-2133 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 Lenovo ThinkCentre M800 Small supports RAM speeds of up to 2133 MT/s.

Wi-Fi Support

Lenovo ThinkCentre M800 Small 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 Lenovo ThinkCentre M800 Small comes with eight 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 Lenovo ThinkCentre M800 Small is featuring a DisplayPort 1.2. 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. However, the Lenovo ThinkCentre M800 Small 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 Lenovo ThinkCentre M800 Small comes with three 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 Lenovo ThinkCentre M800 Small 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 Lenovo ThinkCentre M800 Small comes with a 210 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 210 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.
