Fonte de alimentação DeepCool PL550D 550W ATX 3.0 80 PLUS Bronze, ventoinha 120mm, não modular, 6 SATA, 3x 6+2 PCIe

The PL550D power supply updates DeepCool's non-modular PSUs with a native 12VHPWR cable and brings them into compliance with Intel's ATX 3.0 standard. This 80 PLUS Bronze–certified unit features a 120 mm hydro-bearing fan, premium electrolytic capacitors, and a design intended to deliver stable, long-term power for modern and legacy PC systems.

Advantages

The PL550D supports ATX 3.0 transient response requirements and includes a native PCIe 5.0 (12VHPWR) connector rated up to 300 W, reducing the need for adapters. High-grade electrolytic capacitors and a dual-transistor forward topology with active PFC and DC-to-DC conversion contribute to stable voltages and reliable operation up to 5,000 m altitude. The unit is 80 PLUS Bronze–certified for efficient operation and comes with multiple protection features plus a 5-year limited warranty.

How to use

Install the PL550D into a compatible ATX case and connect the motherboard, CPU (EPS) and graphics card(s) using the provided connectors: two EPS for CPU power, three PCIe for legacy GPU power, and the native 12VHPWR cable for PCIe 5.0–compatible GPUs. Ensure all connections are secure and route cables to maintain airflow. Verify that your case and components support the unit's non-modular design and that the system meets ventilation and clearance requirements before powering on.

Recommendations

Use the native 12VHPWR connector for PCIe 5.0 GPUs when possible to avoid adapters. For optimal reliability, maintain good case airflow and periodically check connections; ensure system power draw remains within the 550 W capacity and consider headroom for peak loads.
