Raijintek ERMIS EVO 750B
The Raijintek ERMIS EVO 750B power supply unit powers the components in ATX-format builds. It provides a total power output of 750W, which is sufficient for running mid-range to advanced gaming and professional workstations. Its power conversion efficiency is confirmed by the 80 PLUS Bronze certification, which defines efficient operation at various load levels and contributes to lower waste heat output. The design fully complies with the Intel ATX 3.1 standard. This standard specifies stricter requirements for stability and the ability to handle high instantaneous power draws. The PSU therefore reliably serves even demanding components and delivers stable power without fluctuations.

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 amount of Watts the PSU can continuously supply to the computer's components. It is a good idea to use a web calculator to determine the optimal power output based on your chosen components.
Stable power and component protection
The internal layout of the PSU is based on a proven topology with a DC/DC converter. This element provides precise and independent voltage regulation on the +3.3V and +5V rails, maintaining a stable output even under uneven loads. The fitted Japanese main capacitors contribute to long-term reliability and effective filtering of voltage ripple, as they are resistant to high operating temperatures and have a longer lifespan. A comprehensive set of integrated protections actively safeguards hardware from damage in case of non-standard operating conditions. The suite includes over-voltage, under-voltage, over-current, and short-circuit protection, which immediately shut down the PSU in a critical situation.
Quiet and efficient cooling
Heat is dissipated from the internal components by a 120mm fan with a fluid dynamic bearing, which operates with low noise and has a longer lifespan than standard sleeve bearings. The fan speed is controlled by an intelligent thermal regulation system that smoothly adapts it to the current load and PSU temperature. During low power draw, such as when working with documents, the fan rotates slowly or stops completely, thanks to Smart Zero Fan technology. This system actively reduces the resulting operating noise and contributes to the quieter running of the entire build. Even at full load, the total noise level does not exceed 29.12dB.
Compact design and tidy cabling
The power supply has compact dimensions with a depth of 140mm. This design makes it easier to install into most standard ATX computer cases and leaves more space for cable management at the back. All cables are firmly attached and have a flat, black profile, which simplifies routing, bending, and securing them to the case structure. Flat cables also promote better airflow inside the build, as they offer less resistance than traditional round bundles. The connector set includes a modern 16-pin 12V-2x6, two 8-pin PCI-E connectors, and five SATA connectors for connecting all necessary peripherals.

80 Plus certification in the European market
The 80 Plus certification was created to objectively evaluate the efficiency of computer power supplies. This gives users a simple and clear way to compare different models. In the European market (where 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.
