ASRock provides a completed M.2 armor solution on B365 platform that makes SSDs to run in a certain low temperature. Dual USB 3.1 Gen2 (Type-A Type-C) This motherboard has a pair of onboard Type-A and Type-C USB 3.1 Gen2 ports built on the rear i/o for supporting next generation USB 3.1 Gen2 devices and to deliver up to 10 Gbps data transfer rates. ULTRA STABLE POWER 5V voltage is transferred from the 12V. Supplying enough current to USB devices without dropping voltage directly from the PSU. ANTISTATIC SHIELD Protect mouse/keyboard against static electricity, especially lowering the chances of USB mouse lag or stuttering. PURE AUDIO QUALITY USB speaker is suggested to be connected via Ultra USB Power ports to perform the pure current and offer high audio quality without distortion. 2oz Copper It comes with 2 ounces copper inner layers, using only carefully selected copper materials for PCB layers, delivering lower temperature and higher energy efficiency for overclocking. PREMIUM 60A POWER CHOKE ASRocks premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
