Can you upgrade Fujitsu Esprimo G6012 to play games?

Fujitsu Esprimo G6012 is a business desktop computer in micro form factor. It is using a processor that provides both the CPU and GPU functionality. While integrated GPUs are sufficient for basic gaming, they are not powerful enough to run demanding games. Fujitsu Esprimo G6012 has no space for dedicated graphics card.

Micro desktop machines like Fujitsu Esprimo G6012 are usually used as home theater PCs (HTPC), in home lab projects or a as home automation servers.

Please explore the sections bellow to find ideas and suggestions on how to upgrade Fujitsu Esprimo G6012.

Windows 11 compatibility

Yes, Fujitsu Esprimo G6012 is compatible with Windows 11. According to Windows 11 specification, all models that have Intel 8th Gen processors (or newer) with TPM 2.0 support and a UEFI BIOS with Secure boot, are eligible to upgrade form Windows 10 to Windows 11 through Windows Update.

GPU upgrade

It is not possible to upgrade Fujitsu Esprimo G6012 with a dedicated GPU due to the lack of space and absence of a PCIe slot. However, you can still use the integrated graphics processor for gaming. There are number of games you can enjoy with an Intel HD and UHD iGPU.


The Fujitsu Esprimo G6012 supports Gen12 Intel Core technology. The 12th generation Intel Core processors were released in 2022. Named Alder Lake they use a hybrid between the Golden Cove and Gracemont architecture. The main differences to the previous generation, is the support for both DDR4-3200 and DDR5-4800 memory. The 12th gen comes with support for the new PCIe 5.0 bus, potentially increasing the bandwidth two times compared to the PCIe 4.0.

Fujitsu Esprimo G6012 has two RAM slots. This is more than enough for most users. For those of you who need extra flexibility and RAM size, go for a model with 4 memory slots.

To cover the needs of your OS, games, and apps, Fujitsu Esprimo G6012 supports up to 64 GB of SODIMM DDR4-3200 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 Fujitsu Esprimo G6012 supports RAM speeds of up to 3200 MT/s.

Wi-Fi Support

Fujitsu Esprimo G6012 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.

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 Fujitsu Esprimo G6012 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. It is nice to see that the model has a USB 3.1 port. This interface is using 10Gb/s connection and it's very useful when you transfer big files to external drives.

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 Fujitsu Esprimo G6012 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. Fujitsu Esprimo G6012 comes with one HDMI 2.1 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 Fujitsu Esprimo G6012 comes with two 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.

Fujitsu Esprimo G6012 has also one M.2 socket(s) that supports both PCIe NVMe (PCIe 4.0 x4) and SATA M.2 drives with speed of up to 8 GB/s. Currently this is one of the fastest commercially available versions of the PCIe bus (second to PCIe 5.0), making this configuration perefect for both gaming and work related tasks.

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.

Best PCIe NVMe drives for Fujitsu Esprimo G6012 storage upgrade:

Model Form factor / Interface NAND type DRAM
Samsung 980 PRO SSD M.2/x4 PCIe 4.0/NVMe TLC Yes
CORSAIR MP600 PRO M.2/x4 PCIe 4.0/NVMe TLC Yes
SAMSUNG 970 EVO Plus M.2/x4 PCIe 3.0/NVMe TLC Yes
Western Digital Black SN770 M.2/x4 PCIe 4.0/NVMe TLC Yes
Kingston A2000 M.2/x4 PCIe 3.0/NVMe TLC Yes

Power Supply

The Fujitsu Esprimo G6012 comes with a 90 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 90 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.
