SUS Prime 300 Series motherboards provide the solid foundation needed for your first build, plus flexibility to grow with your ambitions. We've melded all the good stuff that's packed into the latest processors with essential ASUS design and engineering, so you benefit from industry-leading technologies including automated system tuning, comprehensive cooling controls, and immersive onboard audio. When you build with an ASUS Prime 300 Series motherboard, you build smart, easy and affordably.
Tune it your way Improved DDR4 stability
ASUS OptiMem preserves memory signal integrity by routing traces and vias to the optimal PCB layer, and our T-Topology trace layout ensures time-aligned signaling by balancing trace lengths between memory slots. These enhancements allow the Prime 300 Series to support a wide range of dual and quad-DIMM memory kits, while providing your rig with the stability it needs to deal with any type of workload - whether you're gaming or running intensive applications
Cooler by design
Prime 300 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS. 4-pin PWM/DC fan Each header can be set to monitor and react to up to three thermal sensors. Via Fan Xpert, you can also assign a sensor to monitor the temperature of supported ASUS graphics cards to ensure optimal cooling during GPU- or CPU-intensive workloads.
Media-acclaimed UEFI BIOS
The UEFI BIOS is an early waypoint on any PC-building journey, and Prime 300 Series has one of the best in the business. Q-Fan Control Can configure the fan's operating speed manually, or use the easy pre-configured fan profiles to select Standard, Silent, Turbo or Full Speed modes, plus automatic switch to full speed if the temperature hits 75°C.
Ultrafast connectivityUSB 3.1 Gen 1 front-panel connector
Future-proof connectivity USB 3.1 Gen 1 is right where you need it, with two super-speed headers for the front panel. Experience data-transfer speeds up to 10X faster than USB 2.0 with instant plug-and-play connectivity, and avoid back-breaking contortions in the hunt for hard-to-reach rear ports.
M.2
Speed up with onboard M.2 With x4 PCI Express® 3.0/2.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. It's the perfect choice for an operating system or application drive, providing fast access to data.
Intel Optane memory
Intel Optane memory ready Intel Optane is a revolutionary non-volatile memory technology supported by Prime 300 Series motherboards. Intel Optane memory modules accelerate attached storage to reduce boot and load times, so everything feels faster and more responsive.
Outstanding audio
Combined onboard features deliver elevated audio Intelligent design and premium hardware create audio quality unlike anything you've ever experienced! Audio shielding Separates analog/digital signal domains, significantly reducing multi-lateral interference. Separate layer for left and right tracks Ensures minimal crosstalk between audio paths. Premium Japanese audio capacitors Premium parts provide an immersive sound signature, with exceptional fidelity.
