This document describes the G.SKILL MB850G 850W Power Supply, a component designed to provide stable and efficient power to computer systems.
The G.SKILL MB850G is an 850W power supply unit (PSU) that converts alternating current (AC) from a wall socket into direct current (DC) to power various computer hardware components. Its primary function is to deliver reliable and consistent power to the motherboard, CPU, graphics cards, storage drives, and other peripherals within a computer system. The power supply is designed to ensure that all connected components receive the appropriate voltage and current levels for optimal operation. It features a full modular design, which means that all power cables are detachable. This allows users to connect only the necessary cables, reducing clutter inside the computer case and improving airflow. The unit is also equipped with an ultra-quiet 120mm fan, which provides efficient cooling while minimizing noise during operation.
The G.SKILL MB850G power supply is designed for ease of installation and use, with several features aimed at enhancing the user experience and system performance.
Installation: Before installation, users should ensure the PSU's I/O switch is in the "OFF" (O) position. The PSU is then mounted into the computer case or chassis. Connecting the cables involves attaching the main 20+4pin ATX connector to the motherboard, adapting to 20-pin sockets by detaching the 4-pin connector if necessary. The 4+4pin CPU connector is connected to the motherboard, with users advised to check their motherboard manual for requirements regarding a second set of 4+4pin connectors. For graphics cards, 6+2pin PCIe connectors are used, detaching the two extra pins for 6-pin sockets. SATA connectors power storage drives (HDDs, SSDs) and optical drives, while 4pin molex peripheral connectors power legacy storage, optical drives, fans, or other peripherals. After all connectors are firmly and securely attached, the AC power cord is connected to the PSU and the wall socket, and the I/O switch is flipped to the "ON" (I) position to power on the system.
Cable Management: The full modular design is a significant usage feature, allowing users to select and connect only the cables required for their specific components. This flexibility helps in achieving cleaner cable management within the computer case, which in turn improves airflow and contributes to better overall system cooling. Reduced cable clutter also makes it easier to access components for upgrades or maintenance.
Efficiency: The power supply is 80 Plus Gold Certified, indicating that it achieves up to 90% power efficiency at 50% load. This high efficiency translates into several benefits for the user, including lower energy consumption, reduced heat generation, and quieter operation. Lower heat generation also contributes to the longevity of the power supply and other system components.
Protection Features: The MB850G incorporates a comprehensive suite of protection features to safeguard both the power supply and connected components from electrical and thermal irregularities. These include:
Active PFC (Power Factor Correction): This feature ensures high efficiency power usage, which can lead to more stable power delivery and potentially lower electricity bills.
The G.SKILL MB850G is designed with considerations for long-term reliability and minimal maintenance, though certain user actions are crucial for its proper functioning and longevity.
Troubleshooting: The manual provides a detailed troubleshooting guide for common issues, particularly if the system fails to power on.
Prohibited Actions: To ensure the longevity and safe operation of the power supply, several actions are strictly prohibited:
Technical Support & RMA: For technical support, users can fill out a contact form on the manufacturer's website. For RMA (Return Merchandise Authorization) requests, users should contact the original place of purchase via email or phone. These channels ensure that users can receive professional assistance for any issues or defects, contributing to the overall maintainability and support of the product.
