Dell OptiPlex 5040 MT
Specification and Upgrade Options
The Dell OptiPlex 5040 MT 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, office, and when properly upgraded – gaming. The motherboard is using the Q170 chipset and supports 6th gen Intel Core processor, 16GB of DIMM DDR3L-1600 memory, and dedicated graphics card.
Dell OptiPlex 5040 MT is a Mini Tower form factor computer. The Mini Tower is the largest chassis in the business class desktops segment. If you are looking for a system with maximum upgradability, Dell OptiPlex 5040 MT is a good option. Models in this category usually have 4x PCIe slots, several drive bays and better cooling.
Can you upgrade Dell OptiPlex 5040 MT to play games?
Yes, you can upgrade Dell OptiPlex 5040 MT for gaming with better processors, graphics card, memory, and storage devices. However, like many other business pre-built PCs, this model may have proprietary elements like the power supply, the chassis or the power connector, which can make it difficult for users to install aftermarket PSUs to support better GPUs. You can also find that there is space constrains inside the chassis, making it difficult to accommodete larger GPU to boost the gaming performance.
Please explore the sections bellow to find ideas and suggestions on how to upgrade Dell OptiPlex 5040 MT.
Windows 11 compatibility
No, Dell OptiPlex 5040 MT 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
You can upgrade Dell OptiPlex 5040 MT with a full size GPU. Models like NVIDIA GTX 1660 or GTX 1650 Super are good and safe upgrade option and will work with most Mini Tower form factor. However, keep in mind that the type of GPU you can install will depend on the available space in the chassis and the PSU power rating.
Before you begin shopping for a new GPU, it's important to consider the power supply unit (PSU) currently installed. This is because powerful GPUs require more power than the stock PSU can provide, which means that you may need to upgrade your PSU as well.
According to the manual, the maximum stock power supply available on Dell OptiPlex 5040 MT is 240W. However, to be absolutely sure, check the stock power supply power rating and use one of the GPUs from the table.

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 OptiPlex 5040 MT 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 OptiPlex 5040 MT 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. Dell OptiPlex 5040 MT comes with one HDMI 1.4 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 OptiPlex 5040 MT comes with four 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.
Dell OptiPlex 5040 MT has also one M.2 socket(s) that supports both PCIe NVMe (PCIe 3.0 x4) and SATA M.2 drives with speed of up to 4 GB/s. This configuration works very well 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.
