The extra large aluminum alloy heatsinks take away heat dramatically. As the MOSFETs and chipsets areas are well covered by these heatsinks to protect them from overheating, CPU and chipsets can perform with lower temperature, and your motherboard and system will be more stable and reliable.
Premium Alloy Choke.
The new generation alloy chokes effectively increase up to 90% saturation current and feature a highly magnetic and heat resistant design, making the motherboard more efficient, stable and 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, so the power supply for the CPU Vcore is more efficient.
NexFET MOSFET for Memory Power.
The next generation NexFET MOSFETs control the power supply to DRAM slots more efficiently. They provide lower RDS(on) 2.9 m, delivering higher efficiency and 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 and provide more stability and 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 and gives the motherboard a more mysterious touch.

Had the potential to be an excellent motherboard but it lasted only a few months before having trouble starting. It seems there is a reoccurring problem with this board where it does not power on at all for a few hours if the power supply is unplugged or turned off.

Very nice motherboard had no problems, started up first time no hickups,very happy so far.

Very good board, it supports SLI which I had no problems running, runs for me days on end. No excessive heat and support a variety of CPUs and RAM Speeds. One concern that the HD audio point for the front of your case is at the back above your GPU
