CPU Power & Performance
The ASRock Fatal1ty Z170 Gaming K4 motherboard features a 10-phase power design. This is most likely an 8+2 design, with 8 phases dedicated to the CPU. That ensures a cooler and more efficient power conversion compared to voltage regulator modules (VRM) with fewer phases. Its MOSFETs and inductors are kept cool by large aluminium alloy heatsinks, which helps ensure reliability and longevity of the VRM.
The Fatal1ty Z170 Gaming K4 uses digital pulse-width modulation (PWM) to control its VRM. The PWM is critical in ensuring a stable power supply. Although high quality (and expensive) analog PWM exists, digital PWM allows for more accurate control of the power frequency and modulation.
ASRock also equipped the Fatal1ty Z170 Gaming K4 with Nichicon 12K Platinum capacitors, which not only boasts faster response times and lower voltage noise but also a much longer lifespan (12,000 hours @ 105 °C). In general – this motherboard is designed to last.
To support CPU coolers with two fans, or a DIMM cooler, The ASRock Fatal1ty Z170 Gaming K4 has two CPU fan headers – one on each end of the four DIMM slots.
PCI Express Slots
The ASRock Fatal1ty Z170 Gaming K4 motherboard has 5 PCI Express slots – 2 full-sized PCI Express 3.0 x16 slots, and 3 much smaller PCI Express 3.0 x1 slots. The upper PCI Express 3.0 x16 slot (PCIE2) operates at full x16 speed while the lower PCI Express 3.0 x16 slot (PCIE4) only operates at x4 speed.
The three PCI Express 3.0 x1 slots are of the flexible design. That basically means an open-ended slot. This allows you to use any PCI Express card in those x1 slots, even x16 cards. The only downside is that they will only run at x1 speed.
