The AK-U4-500 power supply meets the requirements of modern computers, which consume the most power on the +12 V line. Therefore, the power supply provides up to 420 W of continuous power on this line in response to demand. What's more, it is characterised by effective cooling when operating at top speed. The 120 mm fan with automatic speed control depending on the component temperature is responsible for the cooling efficiency. In addition, the PSU is equipped with long power supply cables, which allow for its free installation in bottom-mounted enclosures. Moreover, the reliability of the PSU is ensured by an extended warranty for 36 months.
The high efficiency of the power supply is confirmed by the 80 PLUS® Bronze certificate. The power supply meets the requirements of the standard which states that at least 85% of electricity is to be transferred to the powered components. This has a direct impact on energy savings as well as lower heat output.
The power supply is equipped with a number of security features and active PFC filter. They guarantee protection against component damage and stabilize the PSU's operation, so that it runs without any 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 an output current. In case of overload of any of the lines the power supply is automatically switched off.
OPP protection — Protects against power supply overload. It is activated when the power demand is higher than the peak power of the PSU.
OTP protection — Protects against overheating of the PSU, resulting both from overload and insufficient air circulation. In case the safe temperature is exceeded, the PSU is automatically switched off.
UVP protection — Protects against too low a voltage on the output lines. It starts when the voltage drops below an acceptable value. The power supply is automatically switched off.
SCP protection — Protects the PSU against damage caused by a short circuit. The PSU is automatically switched off if a short circuit is detected.

The power supply comes with a wide range of plugs that allow you to connect up to 9 devices equipped with SATA/MOLEX/MINI-MOLEX sockets and a powerful graphics card with two PCI-Express power sockets. The set includes two MOLEX connectors, six SATA connectors for Serial ATA HDDs and optical drives, one mini-MOLEX connector and one universal MPC 24-pin connector. Additionally, the set includes PCI-E 6-pin and PCI-E 6+2-pin for connecting graphics cards and one EPS12V 4+4-pin connector for powering motherboards. In addition, the power supply has a manual switch that allows the user to safely cut off the power supply without having to unplug the power cord from the mains.
