GIGABYTE P850GM power supply unit 850 W 20+4 pin ATX ATX Black

FULLY MODULAR DESIGN
All the black flat cables are modular design. Installing only the cables you need to reduce clutter, to increase the airflow and to improve the chassis thermal performance.

80 PLUS GOLD CERTIFIED
80 Plus Gold certified ensures to deliver 90% efficiency at 50% load. The better power efficiency leads to less power waste, less heat and less fan noise. And with the support of Intel processors, it will save more energy and more money.

HIGH QUALITY JAPANESE CAPACITORS
The main capacitors are high quality Japanese capacitors, to produce the efficient performance and to ensure the longer reliability.

120MM SMART HYDRAULIC BEARING (HYB) FAN
The fan speed is adjusted according to the automatic power detection and will stop when the system is idle or under low load (less than 20% load). The Hydraulic Bearing fan provides longer and more stable life time.

SINGLE +12V RAIL
Single +12V rail provides the best power output, stability and compatibility for the hardware. It provides the easiest way to install the power cable. And it is the best design for overclocking.

PROTECTION
In order to make sure the entire computer system to operate stably under any conditions, we not only added protection designs such as OCP, OTP, OVP, OPP, UVP and SCP, but also ensured the stable operation of your system through the safety certification of various countries.

DIMENSIONS
Compact size to fit any small chassis.

How to use

Install only the required modular cables to connect the motherboard, CPU, GPU and peripherals, routing cables to minimize airflow obstruction. Ensure connectors are fully seated and screws are tightened when mounting the power supply into the chassis. The fan is automatic: it adjusts speed according to system load and will stop when load falls below approximately 20%. Verify system stability after first power-up and monitor temperatures under load. Use the single +12V rail connections for high-current devices and follow component manufacturer guidelines for connector placement.

Recommendations

For best results, match the power rating of this fully modular, 80 Plus Gold power supply to your system’s peak load with some headroom, use only the necessary flat cables to preserve airflow, and ensure your case supports the compact dimensions. Regularly inspect cable connections and maintain case ventilation to maximize lifespan and performance.
