Choosing a power supply
When choosing a suitable PC power supply, the key parameter, besides the form factor, is its wattage. This indicates the maximum number of watts the power supply can continuously deliver to the components in your computer. It is a good idea to use an online calculator to determine the optimal wattage based on your chosen components.
Ready for future components
Compliance with the ATX 3.1 standard means the power supply can handle the high power spikes required by powerful graphics cards. It includes a native 12+4-pin 12V-2x6 connector, which supports PCIe Gen 5.1 graphics accelerators without needing any adaptors. This specification simplifies installation and contributes to a cleaner overall build.
Stability and cable management
The power supply is based on a single strong +12V rail with a current of up to 70.83A, which delivers stable power to key components. This design eliminates the need to split the load across multiple rails and delivers consistent voltage even during demanding tasks. The single rail efficiently handles high transient loads. Organised cabling does not obstruct airflow, contributing to more effective cooling for all components inside the computer, even in smaller builds.
Design with DC-to-DC converters
The internal layout uses DC-to-DC converters to generate the +3.3V and +5V voltage rails from the main +12V rail. This modern topology separates their regulation and increases resistance to asymmetrical loads. The result is more precise output voltage regulation and higher overall efficiency, as the system maintains a stable voltage for all components regardless of the current draw.
Quiet cooling system and protection
Cooling is provided by a 120mm fan with a sleeve bearing, whose speed automatically adjusts to the current load and temperature of the power supply. Under low and medium loads, the fan with intelligent speed control maintains low noise levels and contributes to the quiet operation of the entire computer system. The system thus finds a balance between necessary cooling and acoustic comfort. Safe operation is ensured by eight integrated protection circuits - OVP, UVP, OCP, OPP, SCP, OTP, NLO, and SIP.

80 Plus certification in the European market
The 80 Plus certification was created to objectively evaluate the efficiency of computer power supplies. This provides users with a simple and clear way to compare different models. On the European market (where a 230V voltage 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.
| PC PSU load | Efficiency at 20% load | Efficiency at 50% load | Efficiency at 100% load |
|---|---|---|---|
| 80 PLUS | 82% | 85% | 82% |
| 80 PLUS Bronze | 85% | 88% | 85% |
| 80 PLUS Silver | 87% | 90% | 87% |
| 80 PLUS Gold | 90% | 92% | 89% |
| 80 PLUS Platinum | 92% | 94% | 90% |
| 80 PLUS Titanium | 94% | 96% | 94% |
