Micro Tolerance load regulation Seasonic's latest design keeps the output voltage to a very narrow range, achieving load adjustment below 0.5%. This impressive electrical performance and stability make this power supply an ideal choice for high performance systems. 80 PLUS® Titanium PRIME Gold series is certified 80 PLUS® Gold at 94% efficiency at 50% system load. Fan bearing High-performance fans with dynamic bearing (FDB) were designed to use the effect of oil absorption. They are extremely reliable and generate much less noise and heat during operation than fans with ball bearings. Bearing surface grease reduces friction and vibration and thus reduces overall power consumption. Due to effortless, quieter rotations and robust design, this reliable fan technology significantly prolongs fan life. Cableless structure Seasonic engineers have implemented a new design function in which instead of cables, the rear panel and PCB (printed plate) are connected with copper plate. This breakthrough solution not only reduces the risk of production errors during manual insertion, but also improves the quality of output power.
