The SeaSonic SSP-300TGS is a high-efficiency 300W TFX12V power supply, designed for compact systems requiring stable and reliable power delivery. With an 80 PLUS Gold certification, it offers up to 87% efficiency, reducing energy waste while maintaining optimal performance. Featuring active Power Factor Correction (PFC), it ensures cleaner power delivery across a wide voltage range (100-240V). Engineered with a single +12V rail, it delivers stable power to essential components. The PSU supports Haswell processors and includes multiple safety protections such as short circuit, overvoltage, and overpower protection. Built with a DC-to-DC converter design, it enhances efficiency and reliability while reducing ripple and noise. The cooling system is optimized with a super low noise fan control, making it an excellent choice for quiet environments. With an MTBF of over 100,000 hours, rigorous hi-pot testing, and burn-in high-temperature cycling, this PSU guarantees long-term durability. The unit provides multiple connectivity options, including a 24-pin main power connector, ATX12V 4+4 pin, three SATA connectors, a 4-pin Molex, and an FDD connector, making it ideal for compact desktops and workstations.
