**XXL Aluminum Alloy Heatsink Design.** The extra large aluminum alloy heatsinks take away heat dramatically. As the MOSFETs & chipsets areas are well covered by these heatsinks to protect them from overheating, CPU & chipsets can perform with lower temperature, & your motherboard & system will be more stable & reliable. ** Premium Alloy Choke.** The new generation alloy chokes effectively increase up to 90% saturation current & feature a highly magnetic & heat resistant design, making the motherboard more efficient, stable & reliable. ** Dual-Stack MOSFET for CPU Power.** Dual-Stack MOSFET (DSM) is another innovative MOSFETs design by ASRock. The silicon die area is increased by stacking two dies into one MOSFET. The larger the die area, the lower Rds (on). Compared to traditional discrete MOSFET, DSM with larger die area provides extreme lower Rds (on) 1.2 m O, so the power supply for the CPU Vcore is more efficient. ** Nex FET MOSFET for Memory Power.** The next generation Nex FET MOSFETs control the power supply to DRAM slots more efficiently. They provide lower RDS (on) 2.9 m O, delivering higher efficiency & lower temperature. **12K Platinum Caps.** Supreme 12K platinum capacitors with lifespans of at least 12, 000 hours. Compared to other counterparts on high-end motherboards that merely have lifespans of around 10, 000 hours, these platinum capacitors have 20% longer lifespans & provide more stability & reliability. ** Sapphire Black PCB.** ASRock does not overlook any details, even those tiny ones. With pure black PCB appearance, the new Sapphire Black PCB represents rock-solid quality & gives the motherboard a more mysterious touch.
