For comparison, the SATA III has max speeds of 6Gb/s, while the PCIe 3.0 x4 can go as high as 32Gb/s! Power Supply Sometimes the M.2 slot will only support the inferior SATA III interface. Side note: It is good if the available M.2 slots support the PCIe/NVMe interface. Fortunately the Dell Inspiron 3650 has it and you will be able to enjoy fast transfer speeds with your SSD. Sometimes the M.2 interface will be 5 times faster and more. The M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Think about your use case and decide if the SATA slots provided by this model will be sufficient. Keep in mind that having too few SATA slots might restrict your options for connecting additional memory drives. The Dell Inspiron 3650 comes with 240 SATA slot(s). SATA slots are located on the system board and it is where HDD, SSD and Optical Disk Drives are connected. In case your monitor supports another interface, which this model doesn't have, you can always use an adapter. It is nice to see that the Dell Inspiron 3650 comes with one. It has very similar capabilities to the DisplayPort with few exceptions. HDMI port is another digital video port which allows you to connect external monitors. Check out the HDMI section and make sure that you are at least getting an HDMI port - a good substitution for the DP. It is unfortunate to see that the Dell Inspiron 3650 doesn't have one. If you need a faster connection for your peripherals, like external Solid State Drive, you will need to choose another model.ĭisplayPort (DP) is crucial for any desktop machine as it allows you to connect external monitors. Unfortunately, this model doesn't come with a USB 3.1 port. Higher version of USBs support faster transfer speeds. Having more USB ports is always better, but also pay attention to the version of those USB ports. The Dell Inspiron 3650 comes with 6 USB ports in total. Before buying, considering your use case and plann for extension ports in advance. ![]() For example, if you don't have enough USB ports, using external devices becomes problematic. Ports are something important that people should pay more attention to. The Dell Inspiron 3650 supports a maximum of 16 GB of RAM. For everything else, go for 16GB and more. For everyday work and light gaming we recommend 8GB of RAM. If this happens often, you may see significant drop in performance. It is important not to run out of RAM memory during everyday work. Size of the RAM is another important parameter. #HOW TO REMOVE DELL PRECISION 490 POWER SUPPLY UPGRADE#In case you want faster RAM speeds, you will need to upgrade your system with a newer generation one. The motherboard of the Dell Inspiron 3650 supports RAM speeds of up to 1600 MT/s. This is important for the overall speed of your system. For those who need extra flexibility and RAM size you, go for 4 RAM slots and more.įaster RAM speeds permit your processor to access the data stored in the RAM memory faster. It should be more than enough for most users. Most desktops will have two to four slots. MemoryĪ RAM slot (also called memory socket) is where RAM memory sticks are inserted into the computer. CPUs often used with this model are Core i3 6100, Core i5 6500, and Core i7 6700. Other enhancements include Thunderbolt 3.0 and SATA Express. The improvements are better CPU and GPU performance and reduced power consumption. Named Skylake, it uses the same 14nm manufacturing process like the old 5th gen. Intel introduced the 6th generation of its Core CPUs in August 2015. ![]() For reference in case anyone runs into a similar issue, the fix was replacing the power supply, and I bought a refurbished one for $50.00 on Amazon and that included the wire harness even though I didn't need that.The Dell Inspiron 3650 supports Gen6 Intel Core technology. ![]() This could be coincidence, but it certainly seems like a replacement PSU did the trick!Īs a precaution on overheating I ordered an additional vent fan that can go at the back of the unit, and i ordered new thermal compound (mine is old and dried out). Now when I push the power button it's nearly instant like you would expect. Previously it seemed like I had to hold the power button slightly longer than one would find normal for a PC. Additionally, and this might just be in my head, but it almost seems like pushing the power button is easier. The new PSU does NOT make that noise what so ever. Now since it was faint, and had happened since I got the PC, I always assumed it was a quirk of that model. #HOW TO REMOVE DELL PRECISION 490 POWER SUPPLY PC#Some things I noticed, when I would plug in the PC with the old power supply, it would make a slight squealing noise. After replacing it with the existing wiring harness I powered it on, and it appears to be working like a brand new machine! This is with the replacement X5470 CPUs so they appear to be fine. I got my replacement PSU in the mail yesterday. ![]()
