Product information

Description

The LC-Power LC6850B-SI V3.1 is an ATX power supply unit rated for 850 W total output. It provides a 20+4 pin ATX motherboard connector and meets 80 PLUS Bronze efficiency standards for reliable operation across a wide AC input range of 100–240 V. With compact dimensions of 150×150×86 mm and a weight of 1.88 kg, this PSU is designed for use in desktop PC builds that require stable mid-range power delivery and improved energy efficiency.

Advantages

The unit delivers a continuous 850 W output suitable for mainstream systems and supports universal mains voltages, which simplifies deployment in different regions. 80 PLUS Bronze certification ensures a balance between efficiency and cost, reducing wasted energy and heat compared with non-certified supplies. Its compact footprint helps compatibility with many ATX-compatible cases while keeping installation straightforward through a standard 20+4 pin connector.

Suitable for

  • Mid-range desktop PCs with single GPU configurations
  • Office and home systems requiring stable mains compatibility (100–240 V)
  • System builders looking for cost-effective, energy-efficient PSUs
  • Upgrades where an 850 W output and standard ATX connector are required

Key specifications

  • Total power: 850 W
  • Motherboard power connector: 20+4 pin ATX
  • Efficiency certification: 80 PLUS Bronze
  • AC input range: 100–240 V
  • Dimensions (W×D×H): 150 × 150 × 86 mm
  • Weight: 1.88 kg

How to use

Install the PSU into a compatible ATX case following standard safety precautions: disconnect mains power before installation, secure the unit to the case with the supplied screws, and connect the 20+4 pin ATX connector to the motherboard. Connect other required peripheral and GPU power cables as appropriate for your system. After all connections are made, verify wiring and ensure proper airflow around the unit before powering the system on.

Usage recommendations

For reliable performance, use this 850 W PSU in systems whose combined component power draw stays below the unit's continuous rating, and allow for headroom to accommodate peak loads. Ensure the case provides adequate ventilation and keep dust away from vents and fan areas. If using high-end multi-GPU setups or heavily overclocked CPUs, consider a higher-wattage or higher-efficiency model.
