ASUS Prime A320M-K Cheap Motherboard Review

Some of us do not have much money to spend when assembling a PC. Funds have become a “barrier” for some people in choosing PC hardware. When faced with a fund, someone will definitely choose the cheapest hardware but quite powerful. That’s where beginner-grade hardware comes along like the ASUS Prime A320M-K.

As the name implies, Prime A320M-K is a motherboard that uses AMD A320 chipset though already using a new socket, the AM4, but the chipset is the lowest version offered by AMD. Because using the A320 chipset, Prime A320M-K also can not be overclocked even if you use the best Ryzen processor though.

ASUS Prime A320M-K is a mATH-form factor motherboard, so it’s quite suitable if you want to make a small-sized PC. Minusnya, bebrapa features appear limited. This motherboard only has two DDR4 RAM slots and only one PCIe x16 slot. While the other is PCIe x1 which comes as much as 2 slots.

However, this motherboard is still getting a touch of the latest technology. Prime A320M-K has one M.2 slot that supports SATA and PCIe modes. While other storage options can use four SATA 6Gbps port located at the end of this motherboard.

ASUS Prime A320M-K is powered by two power connectors, one 24-pin connector and one 4-pin connector. It comes with a 6-phase VRM, so from the specs it is predictable that the motherboard does not suck up much power during operation.

Connectivity options offered fairly complete on this motherboard. Through the rear panel, you can connect various devices through four USB 3.0 ports and two USB 2.0 ports. You can also find one ethernet port, 3.5mm audio port, HDMI port, and VGA. Interestingly, this motherboard has two PS / 2 ports so you can still connect your old keyboard and mouse.

What about the performance?

Tested using AMD Ryzen 3 1300X processor which is one of the lowest variants of the Ryzen processor range, this motherboard surprisingly has a performance that is not disappointing. Even its performance in some synthetic benchmarks is similar to the B350 series motherboards that are one level above this motherboard. Here are the benchmark results using PCMark 8 and Cinebench R15:

Gaming performance using this motherboard is also satisfactory. When tested using the ASUS STRIX Radeon RX 480 graphics card, its performance does not vary much when tested on the B350 motherboard. Our three test games, Ghost Recon Wildlands, The Witcher 3, and Ashes of The Singularity can be run with an average framerate above 30fps at the highest graphics settings. This proves that the motherboard is also still very potential even when used in conjunction with upper middle class hardware.


No doubt ASUS Prime A320M-K is one of the preferred motherboards when your funds are very limited. Sold at a price below $100, Prime A320M-K is still very potential even when combined with Ryzen 3 1300X processor whose price is also very affordable. Only, you do not get various features like USB Type-C port. You still have access to use M.2 SSD on this motherboard.
