Dell OptiPlex 7020 SFF

The Dell OptiPlex 7020 SFF was first introduced in 2014. Although this model is more than five years old, it is still a good option for home and office use. You can even turn this PC into a gaming machine by upgrading a low-spec GPU.

The Dell OptiPlex 7020 SFF is a small form factor computer. The small form factor (SFF) is an intermediate model. It has less space for extra hardware than the desktop but is still easily scalable. It usually comes with 2 times the PCIe slot, so it is possible to install a low-end graphics card. SFFs are purchased as everyday computers or as business workstations.


A RAM slot (also called a memory socket) is where RAM is stored on a computer. Most desktops will have two to four slots. This model has 4 RAM slots. This should be enough for anyone, especially for power users who need a significant amount of RAM.

High RAM speeds allow your processor to access data stored in RAM faster. This is important for the overall speed of your system. The Dell OptiPlex 7020 SFF motherboard supports RAM speeds up to 1600 MT / s. If you want faster RAM, you have to upgrade your system to a newer generation.

RAM size is another important parameter. It is important that RAM does not run out during daily work. If this happens too often, you may see a significant reduction in performance. For everyday work and light games, we recommend 8 GB of RAM. For everything else, go for 16GB or more. The Dell OptiPlex 7020 SFF supports up to 16 GB of RAM.


Ports are an important thing that people should pay more attention to. For example, if you do not have enough USB ports, using external devices can be a problem. Before you buy, consider your uses and plan ahead for plugin ports.

The Dell OptiPlex 7020 SFF has a total of 10 USB ports. Having more USB ports is always better, but consider the USB port version as well. Higher versions of USBs support faster transfer speeds. Unfortunately, this model does not have a USB 3.1 port. If you need a faster connection for your peripherals such as Solid State Drive, you should choose another model.

DisplayPort (DP) is very important for any desktop device because it allows you to connect external monitors. It’s good to see that the Dell OptiPlex 7020 SFF has a DisplayPort. The version of this DisplayPort is also important. Always try to target higher versions of DP as it allows for better resolution and refreshes rates.

The HDMI port is another digital video port that allows you to connect external monitors. DisplayPort has very similar capabilities with a few exceptions. However, the Dell OptiPlex 7020 SFF does not have one. If DisplayPort is available, no problem.

SATA slots are located on the system board and connect HDDs, SSDs, and optical disc drives. The Dell OptiPlex 7020 SFF has 255 SATA slots. Keep in mind that having a very small SATA slot may limit your options for connecting additional memory drives. Think about what you are using and decide if the SATA slot provided by this model is sufficient.

The M.2 SSD interface allows you to transfer data faster than the old SATA interface. Sometimes the M.2 interface is 5 times faster or faster. Unfortunately, the Dell OptiPlex 7020 SFF is not included and you have to trust the good old SATA.

Power supply

Having a high-power PSU (power supply unit) is very important, especially if you are going to use components such as a dedicated GPU and an additional hard drive that require extra power. The Dell OptiPlex 7020 SFF has a 255-watt power supply. Deciding whether this is enough depends on your specific needs and usage. Please note that some models may have more than one PSU option. If possible, get the most powerful one as it may make future upgrades easier.
