Seasonic Core Gold GM-650 650W 80+ Gold Modular Power Supply

The Core series from Seasonic represents a re-entry into the market of power supplies and represents a new compact model that includes 80 PLUS Gold efficiency and partially modular cable management that also happens to look fantastic in any setup while providing reliable and quiet operation. This is also due in no small part to the inclusion of a semi-passive 120 mm fan. The smart combination of premium components and materials that all meet the high standards of Seasonic have resulted in a high-quality product for which Seasonic has confidently provided a 7-year manufacturer's guarantee.
  • 650 Watt PSU with powerful 54A single rail
  • High efficiency thanks to 80 PLUS Gold certification
  • Quiet 120 mm fan with S2FC fan control
  • Partly modular cable management with flat cables
  • Four 6+2-pin PCIe connectors for graphics cards
The Seasonic Core GM Gold is capable of supplying a total of 650 Watts, meaning that even high-end PCs will have more than sufficient power. The powerful 12 Volt rail delivers a full 54A. In spite of these impressive specifications, the Seasonic Core GM Gold is also extremely efficient, due largely to Seasonic's use of high-quality components e.g. capacitors. This 80 PLUS Gold-certified power supply has an effective operating efficiency of 90% at a 50% load.

For the purposes of tidiness, the power supply comes with partial cable management. Aside a 24-pin- and a 4+4-pin cable, there are also four 6+2-pin PCIe connectors as well as six SATA- and three 4-pin Molex connectors available. The cables are very flat and thus easy to cable manage.

The 120 mm fan utilises Fluid Dynamic Bearings and offers not only quiet operation, but also reliable operation over the long term. The intelligent S2FC fan control ensures an optimal balance between cooling and operating noise.

It almost goes without saying that the Seasonic Core GM Gold includes all the requisite safety features we have come to expect these days from modern high-end power supplies. Should the PSU suffer an untimely end: not to worry, as Seasonic puts a seven year manufacturer's guarantee on this unit!
