Product information

Description

LC-Power LC6550B-SI V3.1 is an ATX power supply delivering 550 W of continuous power with a standard 20+4 pin ATX motherboard connector and 80 PLUS Bronze efficiency. Designed for mid-range desktop PC builds, the unit accepts a wide AC input range (100–240 V), has compact ATX dimensions (150 × 150 × 86 mm) and integrates a 135 mm cooling fan to maintain stable operating temperatures under typical load conditions.

Advantages

The power supply offers a balanced combination of efficiency and performance, meeting 80 PLUS Bronze standards to reduce energy losses during operation. Its 20+4 pin ATX connector ensures compatibility with a wide range of motherboards while the compact housing and integrated fan simplify installation and thermal management in standard desktop cases.

  • Environments requiring a compact PSU with effective cooling

How to use

Install the LC-Power LC6550B-SI V3.1 into a compatible ATX case following standard PSU mounting procedures: align the unit with the case rear bracket, secure with screws, and connect the 20+4 pin connector to the motherboard. Attach required peripheral and CPU power connectors to components as needed. Verify correct AC mains voltage and connect the mains cable to a properly grounded outlet before powering the system.
