36 months

The AK-U4-350 power supply unit power supply unit is highly efficient, which makes it more effective and reduces energy consumption. The product is characterized by effective cooling during operation at the highest speed, which is solved by a built-in 120 mm fan. The efficiency of the fan is ensured by a controller that controls the speed depending on the temperature of the components. Moreover, long power cables allow free installation in bottom-mounted cases. This, when properly positioned, increases the cooling performance inside the computer case. The reliability of the power supply is ensured by an extended 36 months warranty.

High efficiency guaranteed

The high efficiency of the power supply is guaranteed by the 80 PLUS® Bronze. standard compliance. The certificate ensures that at least 85% of electricity is transferred to the powered components. This has a direct impact on energy savings and lower heat output.

Reliable protection

The power supply is equipped with a number of protections and an active PFC filter. They provide protection, prevent components from damage and stabilize the power supply, so it runs without unwanted interference.

OVP protection — Protects the power supply against too high a voltage on the output line. It is activated when the voltage increases by 15% from the nominal value.

OCP protection — Protects computer components from too high output current. In case of an overload, one of the lines is automatically switched off.

OPP protection — Protects against power supply overload.

OTP protection — Protects against overheating of the PSU caused by overload and insufficient air circulation.

UVP protection — Protects against too low voltage on the output lines.

SCP protection — Protects against short circuit.
