Dobrý den, mám u desky problém s opětovným spuštění po vypnutí pc. PC se vypne a po cca 5s opět samo zapne. Při podržení zap. tl. se zdroj vypne na tvrdo. Flashnutí biosu na poslední verzi 3.11 bez účinku. Ke zdroji byla původně připojena jiná deska, která běžela normálně.
ASROCK Z890 PRO RS WIFI WHITE

ASROCK Z890 PRO RS WIFI WHITE
The ASROCK Z890 PRO RS WIFI WHITE motherboard with an Intel Z890 chipset and LGA1851 socket is an advanced solution for builds with Intel Core Ultra Series 2 processors, combining high performance, effective cooling, and modern connectivity in a white ATX format. The board has an advanced power system with 16+1+1+1+1 power stages equipped with Dr.MOS technology, which ensures a stable power supply even during demanding overclocking. Memory support includes four DDR5 slots with overclocking capabilities up to 9066MHz via Intel XMP or AMD EXPO profiles, while the patented Memory OC Shield minimises electromagnetic interference for maximum stability at high frequencies.
Key features of the ASROCK Z890 PRO RS WIFI WHITE motherboard
- Supports Intel Core Ultra Series 2 processors with LGA1851 socket and Intel 200S Boost technology for a performance upgrade via a BIOS update
- Powerful 16+1+1+1+1 phase power design with Dr.MOS technology, 1000µF capacitors, and Hi-Density connectors ensures a stable power supply during demanding overclocking
- DDR5 memory up to 9066+ MHz (OC) with Memory OC Shield technology reduces electromagnetic interference and increases stability during high-frequency operation
- Storage interface with one M.2 PCIe Gen5 x4 (128 Gb/s) slot, three M.2 PCIe Gen4 x4 slots, and extended XXL aluminium heatsinks with bottom cooling
- Intelligent cooling with aluminium heatsinks, automatic PWM/DC fan detection, Fan-Tastic Tuning function, and reinforced PCIe 5.0 steel slots
Power system and stability
The board's power subsystem uses a robust 16+1+1+1+1 power stage design fitted with Dr.MOS components, which intelligently deliver higher current to each phase while lowering operating temperatures compared to traditional discrete MOSFETs. The board is equipped with highly durable 1000µF capacitors and Hi-Density power connectors, which can handle higher currents than traditional connectors and reduce the risk of overheating during demanding overclocking. The two-ounce copper inner PCB layers contribute to lower temperatures and higher energy efficiency, while support for Intel 200S Boost technology enables higher performance from Intel Core Ultra processors via a BIOS update.
Memory support and storage
The four DDR5 slots support a dual-channel architecture with overclocking capabilities up to 9066MHz via pre-set Intel XMP or AMD EXPO profiles, while the Memory OC Shield technology reduces electromagnetic interference that could affect memory overclocking stability. The storage subsystem offers four SATA III connectors and a total of four M.2 connectors, including one with PCIe Gen5 support for the fastest SSDs. Expansion options include one PCIe 5.0 x16 slot with steel reinforcement, two PCIe 4.0 x4 slots, and one PCIe 4.0 x1 slot.
Connectivity and features
Connectivity is provided by two Thunderbolt 4/USB4 Type-C ports with transfer speeds of up to 40 Gb/s, a Dragon 2.5 Gb/s LAN network interface, a Wi-Fi 6E wireless module with 6GHz band support, and an extensive range of USB ports, including a USB 3.2 Gen2x2 Type-C connector for the front panel with speeds of 20 Gb/s.
