Lenovo ThinkCentre M93 Small Pro
Specification and Upgrade Options
The Lenovo ThinkCentre M93 Small Pro is a pre-built business desktop computer first released in 2013. Although more than five years old, it is still a viable solution for home and office. The motherboard is using the Q87 chipset and supports 4th gen Intel Core processor, 32GB of DIMM DDR3-1600 memory, and a low profile GPU. You can even make a gaming PC form this machine with a proper GPU upgrade.
Lenovo ThinkCentre M93 Small Pro is a Small form factor computer. The Small Form Factor (SFF) is an in-between model. It has less space for the larger form factors (Mid tower, Mini tower, and Desktop), but it is still easily upgradable. Usually the SFF come with 2x PCIe slots, so fitting a low profile graphics card is possible.
Can you upgrade Lenovo ThinkCentre M93 Small Pro to play games?
Yes, you can upgrade Lenovo ThinkCentre M93 Small Pro 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 Lenovo ThinkCentre M93 Small Pro.
Windows 11 compatibility
No, Lenovo ThinkCentre M93 Small Pro 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
To upgrade the GPU of OptiPlex 7040 SFF, a low-power, low-profile graphics card must be used. Currently, the most reasonable GPU option is AMD's Radeon RX 6400 low profile. This model has a good price point, delivers decent FPS, and does not require any addtional hardware upgrades.
The low power requirements of this model make it the perfect option for an SFF gaming build. The RX 6400 low does not need any additional power from the PSU and can rely solely on the power delivered by the PCIe slot (75W).
GPU upgrade options for Lenovo ThinkCentre M93 Small Pro with the stock 240W power supply:
| GPU | Power consumption | Memory | Req. |
|---|---|---|---|
| RX 6400 Low profile | 50 W | 4 GB DDR6 | Works with no additional hardware changes |
| GTX 1050 Ti Low profile | 75 W | 4 GB DDR5 | Works with no additional hardware changes |
| GTX 1650 Low profile | 75 W | 4 GB DDR5 | Works with no additional hardware changes |
| RTX A2000 Low profile | 70 W | 6 GB DDR6 12 GB DDR6 |
Works with no additional hardware changes |
Keep in mind that these low-profile, low-power GPUs can be quite noisy and may run hot when under full load.
Processor
The Lenovo ThinkCentre M93 Small Pro supports Gen4 Intel Core technology. The 4th generation was released in 2013 and under the codename Haswell. They adopt the same 22nm manufacturing process as its predecessor. The performance improvement of Haswell compared to the Ivy Bridge is around 8%. The 4th gen comes with support for new sockets (LGA 1150, LGA 2011-3), DDR4 RAM and a new cache design.
Best CPUs for Lenovo ThinkCentre M93 Small Pro upgrade:
| Model | Cores (Threads) | Base frequency | Turbo |
|---|---|---|---|
| Core i5 4690 | 4(4) | 3.5 GHz | 3.9 GHz |
| Core i7 4770 | 4(8) | 3.4 GHz | 3.9 GHz |
| Core i7 4790 | 4(8) | 3.6 GHz | 4.0 GHz |
Memory
Lenovo ThinkCentre M93 Small Pro 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 M93 Small Pro supports up to 32 GB of DIMM DDR3-1600 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 M93 Small Pro supports RAM speeds of up to 1600 MT/s.
Wi-Fi Support
Lenovo ThinkCentre M93 Small Pro doesn't come with any on-board Wi-Fi support. In that case, you have two options to upgrade this model with Wi-Fi. You either use an external USB Wi-Fi adapter (wireless network dongle) or a PCIe-based wireless adapter.
The USB dongle is much more convenient and easy to install, but has less space for a decent antenna and can have thermal problems. On the other hand, the PCIe based adapter is much more powerful, more reliable, and has better antenna, but it is harder to install.
Wi-Fi and Bluetooth wireless adapter upgrades for Lenovo ThinkCentre M93 Small Pro:
| 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
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 M93 Small Pro 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 M93 Small Pro 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 M93 Small Pro 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 M93 Small Pro 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.
Unfortunately, the Lenovo ThinkCentre M93 Small Pro 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 M93 Small Pro comes with a 240 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 240 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.
