Dell Pro Micro Plus QBM1250 vs. Dell Pro Tower QCT1250
Comparison and Differences
Differences between Dell Pro Micro Plus QBM1250 and Dell Pro Tower QCT1250
Both computers, the Dell Pro Micro Plus QBM1250 and the Dell Pro Tower QCT1250, were released during the same year - 2025.
If you are looking for the smaller form factor the Dell Pro Micro Plus QBM1250 is the right one for you. It is smaller than the Dell Pro Tower QCT1250 and will fit more easily under your desk.
Processor
The two models have the same generation of Intel processors. We think that the 16 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.
Memory
Both models have have equal amount of ram slots (2 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.
None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 6400. In addition, you will be able to install the same amount of RAM in both models, and most probably 64 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.
Ports
Both models have the same amount of USB ports for total count of 8. If this is not enough, using a USB hub is always a viable option. What is nice about the Dell Pro Micro Plus QBM1250, is that it has 5 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell Pro Tower QCT1250 has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell Pro Micro Plus QBM1250 comes with 3 ports, while the Dell Pro Tower QCT1250 has only 1. If you are planning to use multiple monitors, the Dell Pro Micro Plus QBM1250 is the better choice.
The Dell Pro Tower QCT1250 comes with an HDMI port, while the Dell Pro Micro Plus QBM1250 does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).
SATA ports are placed on the system board and it is where you connect your HDD, SSD and Optical Disk Drives. More SATA slots will allow you to have more drives running at the same time. In this regard the Dell Pro Tower QCT1250 is better equipped as it comes with 2 SATA slot(s), while the Dell Pro Micro Plus QBM1250 has 0 slot(s).
An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the Dell Pro Micro Plus QBM1250 has 1 M.2 slots while the Dell Pro Tower QCT1250 comes with just 1.
Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6Gb/s, while the PCIe 3.0 x4 will support speeds up to 32Gb/s!
Power Supply
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The Dell Pro Micro Plus QBM1250 comes with a decent 180 Watt PSU, but the Dell Pro Tower QCT1250 has a more powerful one rated at 360 Watts. Choosing either one depends on your specific requirements and use case. Also don't forget that some models might have more than one PSU option - try to always get the most powerful one, especially if you plan to upgrade to a powerful GPU.
