Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the form factor is its power output. This indicates the maximum number of watts the PSU can continuously supply to the components in your computer. It is a good idea to use an online calculator to work out the optimal power output based on your chosen components.
ATX 3.0 and protection features
Full compliance with the ATX 3.0 standard means the PSU is designed to handle the short-term power spikes that modern components can create. The native 12V-2x6 connector enables direct power for PCIe 5.0 standard graphics cards without using adaptors. This solution reduces potential compatibility issues and ensures adequate power even for more powerful graphics cards. A set of six protection circuits serves to protect connected components during unstable power supply. It includes overvoltage, undervoltage, overcurrent, overload, short circuit, and overheat protection.
Efficiency and two 12V rails
The 80 PLUS Gold certification indicates the PSU's operational efficiency, which reaches up to 93.2% at approximately 50% load. Lower energy losses mean less waste heat is produced, which can lead to quieter system operation and lower electricity consumption. This means the fan does not have to run at high speeds. Higher efficiency also reduces thermal stress on the components. The PSU uses two separate 12V rails to power more demanding components. The first rail provides 40A and the second 36A, meeting the requirements of modern hardware. This power distribution enables stable power for processors and graphics cards even under heavy load.
Quiet operation and topology
The 120mm fan helps maintain the PSU's operating temperature at a low noise level. Its speed adapts to the current load. The Rifle bearing and four-pole motor contribute to a longer lifespan and stable operation. The blade shape is designed to limit turbulence and noise, which can reach up to 26dB(A). This ATX 3.0 standard PSU uses a topology with LLC, Synchronous Rectifier (SR), and DC/DC technologies. LLC contributes to more stable operation under higher loads, while SR helps increase efficiency. The DC/DC converters ensure regulated voltage for the 3.3V and 5V rails.
Fully modular cabling
Fully modular cable management means that all cables can be disconnected. This makes it possible to connect only those that are needed to power the components. This approach simplifies both installation and the organisation of the internal space. Most of the cables have a flat profile, which makes them easier to route behind the motherboard and helps keep the inside of the case tidy for effective cooling.

80 Plus certification in the European market
The 80 Plus certification was created to objectively assess the efficiency of PC power supplies. It gives users 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, each with set requirements for PC power supplies. Higher energy efficiency primarily means lower energy consumption.
| PC power supply 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 % |
