SeaSonic G12 GC-750 (SSP-750RT2)

The SeaSonic G12 GC-750 (SSP-750RT2) is an ATX-format power supply unit with 80 PLUS Gold certification, designed to reliably power high-performance gaming and workstation PCs with a 750 W capacity reserve. The unit employs Active Power Factor Correction (Active PFC) and an LLC resonant converter topology to maintain high efficiency and stable voltage output. The +12 V rail is the primary power line, capable of delivering up to 62 A—equivalent to 744 W on +12 V—which is essential for modern graphics cards and processors under sustained loads. Safety features include OPP/OVP/SCP/UVP protection, while cooling is provided by a 120 mm fan with SeaSonic's proprietary Smart and Silent Fan Control (S²FC) algorithm that adjusts fan speed based on temperature. The SeaSonic G12 GC-750 (SSP-750RT2) features fixed cables, which simplifies installation without the need to source compatible modular connectors; however, careful cable management within the chassis is recommended. The connector array includes 1×24-pin (20+4) ATX for the motherboard, 2×EPS/CPU 8-pin (4+4) for processor power, 4×PCIe 6+2-pin for graphics cards, 6×SATA for storage drives, and 3×Molex for peripheral devices. The main ATX cable measures 550 mm in length, while CPU cables measure 600 mm; the power supply dimensions are 150×140×86 mm, ensuring compatibility with most ATX cases. The SeaSonic G12 GC-750 (SSP-750RT2) is well-suited for builds where a powerful +12 V rail, Gold-level efficiency, and a comprehensive connector set for multiple drives and graphics cards are priorities.
