I bought a prebuilt mid-range gaming PC in 2020, but newer games are starting to exceed its minimum requirements. I understand how to choose major parts such as the CPU, GPU, and motherboard, but I'm less familiar with selecting the power supply, cooling, and other supporting components.
I'm considering either making a few targeted upgrades or replacing most of the system. My current hardware is an ASUS Prime B360-Plus motherboard, an i5-9400F, a GTX 1660 Super 6GB, and 16GB of DDR4-2666 memory. I don't know the exact PSU model because the retailer didn't list it, and I'm unsure whether the existing case, storage, cooler, or power supply could be reused.
For a complete rebuild, my budget would be around $1,600–$1,800. Is this system worth upgrading, and what should I check when choosing the PSU, cooling, and other secondary components?

A sensible middle ground is to replace the platform and GPU while reusing the case, storage, and DDR4 memory if they’re in good condition. Your current CPU and motherboard are fairly limiting for newer games, while the 1660 Super is also the biggest obstacle for high-quality 1440p gaming. A newer DDR4-compatible platform can reduce the cost, but make sure the board supports the processor and that the power supply is suitable for the new graphics card. Don’t assume the original cooler or PSU is reusable just because they still work.
Before recommending parts, confirm the exact RAM configuration, especially whether it’s one or two sticks, and identify the PSU model and wattage. The PSU label is usually visible through a case vent, or you can remove the side panel and read it directly. The model matters more than wattage alone, since an old or low-quality unit may not be worth reusing. Also check the case’s GPU length, radiator or CPU-cooler clearance, storage connections, and airflow support.
The memory runs at 2666MHz. I still need to open the case to identify the PSU, since the retailer didn’t provide those details. My full-build budget would be roughly $1,600–$1,800.
A high-end X3D processor such as the 9800X3D is excellent for gaming, but it’s more of a premium choice than a direct mid-range equivalent. Pairing a cheaper modern CPU with a stronger GPU may provide better value at 1440p, where the graphics card generally matters more. Choose the CPU and GPU together based on your target resolution, frame rate, and the games you play rather than spending most of the budget on the processor.
For a full rebuild, plan the power supply around the graphics card’s recommended wattage and choose a reputable modern unit with the appropriate PCIe connectors and efficiency rating. For cooling, check the CPU’s power draw, socket compatibility, cooler height, and case airflow. Two or three quality case fans are usually enough for a normal gaming system; you don’t need an expensive liquid cooler unless the CPU specifically benefits from one. Also remember that DDR4 cannot be carried over to an AM5 build, because AM5 uses DDR5.
That sounds much cheaper than replacing everything. I’m currently playing demanding games at 1080p on medium settings around 60 FPS, so a modern platform and GPU would be a major improvement.
