Choosing a power supply

When choosing a suitable PC power supply, the key parameter, besides the format, is its power output. This indicates the maximum number of watts the PSU can continuously supply to the computer's components. It's a good idea to use a web-based 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 better handles the high and sudden power spikes demanded 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 on the Seasonic Core GX-650

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 series cards. This solution eliminates the need for adapters 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 wide compatibility, the package also includes an adapter from the 12V-2x6 connector to two standard 8-pin PCIe connectors. This element is for the seamless connection of older graphics cards that do not use 16-pin power. The fully modular cabling system gives the user control over which cables are used in the build. You only connect those necessary to power specific components, and the rest remain safely stored away. The result is significantly easier cable management and fewer obstructions to 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 a film of oil to reduce friction and vibration. The fan therefore operates at a low noise level and has a longer lifespan compared to standard sleeve or ball bearings. The system's operation is quieter, even under higher loads.

S2FC technology of the Seasonic Core GX-650 power supply unit

The intelligent S2FC fan control maintains a balance between effective 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, such as when working with documents, the fan rotates at a minimal speed, reducing noise to an almost inaudible level.

Heat dissipation with OptiSink technology

The internal design uses a redesigned PCB layout and OptiSink technology. This specially shaped heatsink improves heat dissipation from high-stress components such as MOSFET transistors and diodes. More effective cooling increases power stability under high load and extends the operational life of the power supply.

80 PLUS Gold efficiency of the Seasonic Core GX-650

The 80 PLUS Gold certification confirms the power supply's high energy efficiency. At 50% load, it achieves up to 90% efficiency. The PSU converts more energy from the mains into usable power for components and produces less waste heat. Lower heat 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 suite of six key protection features that safeguard connected components from damage. These include Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Current Protection (OCP), and Over Power Protection (OPP). It also features Short Circuit Protection (SCP) and Over Temperature Protection (OTP), which together form a comprehensive safety system for the entire computer build.

80 Plus certification on the European market

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

Prosím dotaz ohledně nadměrné hlučnosti. Pokud ho z vás již někdo vlastní, můžu se zeptat na jeho hlučnost. Není to o cvakání nebo rachocení, ale zkrátka ventilátor jede více než jsem čekal a tichý tedy určitě není :/ Má s tím někdo stejnou zkušenost?
