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 wattage the power supply can continuously deliver to the computer's components. It is a good idea to use a web calculator to work out the optimal power based on your chosen components.
Computer power supply reliability
The foundation of the power supply is its Japanese main capacitors, known for their resistance to high temperatures. Their use contributes to a longer lifespan and better filtering of low-ripple noise. Thanks to them, the power supply provides reliable performance even under demanding and prolonged loads. Precise voltage control on individual rails is handled by a modern topology with DC-to-DC converters for a stable power delivery.
Quiet cooling
Heat dissipation is handled by a fan with a fluid dynamic bearing and intelligent thermal speed control. At low loads, the Smart Zero Fan technology keeps the fan from spinning, resulting in silent operation. The fan activates automatically only under higher loads, when it efficiently cools the internal components with a maximum noise level of 29.12dB(A).
Connectivity and easy installation
The power supply uses fixed, flat black cables, which simplify cable management and promote better airflow in the case. Thanks to its compact depth, the Raijintek ERMIS EVO 650B is easy to install even in smaller computer cases. The connector set includes a modern 12V-2x6 16-pin connector for graphics cards and plenty of connectors for other components.

80 Plus certification in the European market
The 80 Plus certification was created to objectively assess the efficiency of computer power supplies. It gives users a simple and clear way to compare different models. In the European market (where a 230V voltage 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.
| 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 % |
| 80 PLUS Platinum | 92 % | 94 % | 90 % |
