Description
Today I'll be having a look at an 80+ Gold power supply. Basically this is a super efficient, but low wattage power supply. For most computers this is the most efficient configuration because at about 50-60% load, this PSU can provide 90% efficiency and very low noise levels and most computers do not draw more than about 250-325W under load.
The video provides an in-depth unboxing and first look at the Seasonic X-Series 650W 80 Plus Gold certified power supply. The host details the packaging, notes the gold accents and branding, and highlights the DC-DC converter technology as part of the 80 Plus Gold certification, emphasizing that the unit maintains high efficiency across loads, with claims of up to 87% efficiency at typical gaming loads and very low noise due to a PWM fan that only spins when necessary. The unboxing reveals the modular cable set, a velvet storage bag, and various included accessories such as case badges and mounting screws. The host walks through the rear and side labeling to explain the single rail design, the fully modular interface, and the peculiar two-piece 24-pin to 16-pin adaptation, pointing out how the cables are organized for different configurations. He then examines the included cables in detail, including two PCI Express power cables, a four-pin CPU connector, multiple SATA/Molex options, and the unique approach to modularity that retains flexibility while encouraging safe usage. Throughout, there is a mix of practical observations about build quality, cable management, and the practicalities of fitting the PSU into common mid-tower cases, with occasional humor and qualifying remarks about expected noise levels and efficiency in real-world setups. By the end, the reviewer summarizes the product’s strengths for enthusiasts seeking a quiet, well-built power supply with a strong warranty and accessible diagnostics, while noting the potential confusion around the dual-cable approach for the main 24-pin connector. The overall takeaway is that the Seasonic X-Series 650W is presented as a premium, reliable option for systems in the mid-range power envelope, combining solid efficiency, modular design, and thoughtful cable/connectivity options that support clean builds.
