Seasonic Core GX-650 ATX 3.1 White
The Seasonic Core GX-650 PC power supply delivers a stable 650W output to power components in both gaming and workstation builds. Thanks to its 80 PLUS Gold certification, it achieves high energy efficiency, which means less wasted energy and lower heat output. Full compatibility with the ATX 3.1 standard prepares it for future generations of hardware and reliably handles high power spikes. S2FC technology controls the speed of the quiet fan with its fluid dynamic bearing. The fully modular cable management, in a white finish, helps to create a tidy case interior, optimises airflow, and complements the aesthetics of builds with a glass side panel.

Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the form factor is the power output. This indicates the maximum number of watts the power supply can continuously supply to the computer's components. It's a good idea to use a web calculator to work out the optimal power output based on your chosen components.
ATX 3.1 and PCIe 5.1 standard
Support for the ATX 3.1 standard means the power supply can better handle the high and sudden power spikes required by powerful graphics cards and processors. This gives the system a stable and reliable power supply even under heavy load. Compliance with the PCIe 5.1 specification is related to direct support for the powerful graphics accelerators on the market.
Native 12V-2x6 connector
The power supply includes a native 12V-2x6 connector, which is used for the direct connection of PCIe 5.1 standard graphics cards, such as NVIDIA GeForce RTX 40 cards. This solution eliminates the need for adaptors and reducers when building your system. A direct connection reduces the risk of incorrect wiring and contributes to a cleaner look inside the case.
Fully modular cabling of the Seasonic Core GX-650
To maintain broad compatibility, the package also includes an adapter from a 12V-2x6 connector to two standard 8-pin PCIe connectors. This element is used for the seamless connection of older graphics cards that do not use 16-pin power. The fully modular cabling system gives you control over which cables are used in the build. You only connect those that are essential for powering specific components, and the rest remain safely stored away. The result is significantly easier cable management and fewer obstacles for airflow. Better airflow then improves the overall cooling of the case and makes future maintenance easier.
Fluid dynamic fan bearing
Cooling is provided by a fan with a fluid dynamic bearing (FDB). This type of bearing uses an oil film to reduce friction and vibration. The fan therefore operates with a low noise level and has a longer service life compared to standard sleeve or ball bearings. The system's operation is quieter, even under higher loads.
S2FC technology of the PC power supply
The intelligent S2FC fan control maintains a balance between efficient cooling and quiet operation. The system actively adjusts the fan speed according to the current load and the temperature of the power supply. At low loads, for example when working with documents, the fan spins at a minimal speed, reducing noise to an almost inaudible level.
Heat dissipation with OptiSink technology
The internal design uses a redesigned printed circuit board layout and OptiSink technology. This specially shaped heatsink improves heat dissipation from high-stress components such as MOSFET transistors and diodes. More efficient cooling increases power stability under high load and extends the operational life of the power supply.
80 PLUS Gold efficiency of the Seasonic power supply
The 80 PLUS Gold certification confirms the power supply's high energy efficiency. At 50% load, it achieves an efficiency of up to 90%. The power supply converts more energy from the mains into usable power for the components and produces less waste heat. Lower thermal losses directly contribute to lower running costs and less strain on the entire system's cooling.
Comprehensive system protection with the Seasonic Core GX-650
The power supply integrates a set of six key protection features that safeguard connected components from damage. These include over-voltage, under-voltage, over-current, and overload protection. Short-circuit and over-temperature protection are also present, which together form a comprehensive safety system for the entire computer build.

80 Plus certification in the European market
The 80 Plus certification was created to objectively assess the efficiency of computer power supplies. This provides users with a simple and clear way to compare different models. On the European market (where 230V is used), there are six levels of 80 Plus certification with set requirements for PC power supplies. Higher energy efficiency primarily means lower energy consumption.

|---|---|---|---|
| 80 PLUS | 82 % | 85 % | 82 % |
| 80 PLUS Bronze | 85 % | 88 % | 85 % |
