ASUS PRIME A320M-K - Motherboard - micro ATX
ASUS Prime is the next evolution of the ASUS motherboard, born of a pedigree that stretches back to 1989. The team of excellent engineers are passionate about empowering everyone to enjoy the benefits of customization and tuning, and the driving force behind the development of Prime is to make advanced enthusiast controls easily accessible - maximizing performance, stability and compatibility for great DIY PC experiences. Simply stated: it's time for Prime.
5X Protection III
PRIME A320 series motherboards are engineered with 5X Protection III, employing fine components, excellent circuit design, and exacting standards to guarantee the quality and long-term durability of your motherboard. That means exceptional protection and stability for your build.
SafeSlot Core is the ASUS-exclusive PCIe slot. Featuring a fortified design that's anchored to the motherboard by a special hook, Safeslot Core provides stronger retention and greater shearing resistance than standard expansion slots.
ASUS LANGuard is hardware-level networking protection that employs signal-coupling technology and premium anti-EMI surface-mounted capacitors to ensure a more reliable connection and better throughput, plus electrostatically guarded and surge-protected components for greater tolerance to static electricity and improved protection against surges.
An exclusive circuit design with built-in voltage regulators to protect your chipset, connectivity ports, and audio codecs from damage caused by unexpected high-level voltages from unstable or inferior power supplies.
ASUS ESD Guards prevent damage from electrostatic discharge, up to +/- 10 kV for air discharge and +/- 6 kV for contact discharge, arranged in an active-protective-circuit design that prolongs the life of components.
Dedicated CPU and case fan controls
Exclusive Fan Xpert ensures every fan achieves the best balance of cooling performance and low noise - and with Prime A320 series boards and their hardware-level 4-pin/3-pin PWM/DC mode for case fans, a simple BIOS adjustment lets you run your case fan in PWM/DC. Fan Xpert even includes Auto-Tuning mode to scan and detect all fan characteristics for single-click customization!
With the energy processing unit you'll enjoy system power savings. EPU automatically optimizes power consumption, and maximizes savings with Away mode.
Speed up with onboard M.2
With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32 Gb/s data-transfer speeds. It is the perfect choice for an operating system or application drive, making your whole PC or professional apps work as fast as possible.
Effortless PCI Express component removal
The large winged clip is easy to reach and easy to operate. Just press the Q-Slot clip lightly, and the graphics card pops out. Installing or removing even the biggest graphics cards is no sweat!
Easy memory removal
Even if you work with a smaller case, just push down on the one-sided clip and push or pull RAM modules in or out - removing memory is that simple!
