ASRock Z390 Phantom Gaming 4S
The Z390 Phantom Gaming 4S offers all the essentials you need to build a well-rounded gaming PC based on the 9th / 8th gen Intel Core processors. Boasting superb power delivery and advanced circuitry, this ATX board has two PCIe x16 slots and a PCIe M.2 slot for ultra-fast SSD storage. The board also looks great, sporting sapphire black PCB accented by contrasting white strip lines and geometric heatsinks.
This motherboard features onboard RGB headers and an addressable RGB header that allow motherboard to be connected to compatible LED devices such as strip, CPU fans, coolers, chassis and so on. Users may also synchronize RGB LED devices across the Polychrome RGB Sync-certified accessories to create their own unique lighting effects.
* The addressable RGB LED header supports WS2812B addressable RGB LED strip (5V/Data/GND), with a maximum power rating of 3A (5V), a max of 80 LEDs and length within 2 meters.
* The RGB LED header supports standard 5050 RGB LED strip (12V/G/R/B), with a maximum power rating of 3A (12V) and length within 2 meters.
The PCIe Gen3 x4 Ultra M.2 interface pushes data transfer speeds up to 32Gb/s. In addition, it is also ready for higher capacity and even faster Type 22110 M.2 NVMe SSD to fulfill the need of performance.
POOL (Planes On Outer Layers) technology allows 4-layer boards to utilize stripline routing instead of micro-strip routing, making motherboard having better electrical properties and performance.
Intel LAN provides the best throughput performance, lower CPU utilization, enhanced stability and is able to deliver ultimate network experience to users!
Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch.
High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.
Delivering data transfer rates up to 10X faster than USB 2.0 with optimized power efficiency. USB 3.2 Gen1 technology advances the data transfer rate up to 5Gb/s. ASRock provides 4 x USB 3.2 Gen1 ports onboard allows you to have a stunning data transfer experience.
Post Status Checker
An easy troubleshooting tool that shows the CPU / DRAM / VGA / BOOT operation every time you start up the system. Post Status Checker is a fast and easy way to identify the source of the problem.
Water Pump Header
This is not only a standard CPU fan header, but also supports water pumps! This header provides a maximum of 2A power for supporting the most popular water pumps. User also can adjust the voltage of water pump to get higher cooling performance with lower noise.
Digi Power
Unlike traditional motherboards that use analog power, this motherboard uses a next generation digital PWM (Pulse-Width Modulation) design, which provides CPU Vcore voltage more efficiently and smoothly, so that the stability and lifespan of the motherboard is greatly enhanced.
M.2 (KEY E) For WiFi
Besides the onboard LAN port, users may also choose 802.11ac wireless connections by M.2 (Key E) slot.
* Wi-Fi module is not included.
Solid Capacitor Design
ASRock applied solid capacitors on this motherboard. With these solid caps, this motherboard is allowed to perform more stably and ensure longer lifetime.
ELNA Audio Caps
Who says high quality audio is only available on high-end motherboards? ASRock applied ELNA audio capacitors on mainstream and entry-level motherboards! Compared with traditional solid caps, the leakage current of ELNA audio caps is merely 3uA. This is the key to reduce noise level significantly and satisfy even the pickiest audiophiles.
Full Spike Protection
Some sensitive digital components on the motherboard are vulnerable to power surges, the excessive current may cause your system to malfunction immediately. ASRock Full Spike Protection includes various technologies to prevent your motherboard’s components from being damaged by these unexpected voltage spikes.
