Seasonic SS-400L1U 400W - PSU, 80 Plus Gold

The Seasonic SS-400L1U is a power supply unit designed for systems requiring up to 400 watts of continuous power. It operates with an 80 PLUS Gold certification, indicating a high level of energy efficiency during conversion, which minimizes heat waste. The unit's fully modular cabling system allows for the attachment of only necessary cables, aiding in better airflow and cleaner cable management within the PC case. This design is particularly useful for builds where internal space is a primary consideration.

This power supply incorporates a 40 mm fan for active cooling to maintain optimal operating temperatures under load. The internal components are safeguarded by a suite of protection features, including over voltage, over power, and short circuit protection, which help prevent damage to connected hardware.
