High-performance power supply for multi-GPU systems

The Akyga AK-U4-800 power supply is a stable and, most importantly, reliable power source. These features are especially important for anyone who relies on their computer equipment. Regardless of whether it is used for work or study. What's more, the power supply is also characterised by high efficiency and energy saving, which are increasingly important nowadays.

Work without restrictions

Max power
800 W

Fan dimensions
12 cm

Cable length
45-75 cm

36 months

The power supply meets the requirements of advanced PC systems. More complex configurations need a strong +12V line, which is why this model features up to two powerful +12V lines. Each of these is able to deliver a current capacity of 28A. Thus, the connected components, such as CPU or graphics cards, enjoy a high level of power stability. Furthermore, the PSU is equipped with two PCI-E connectors, which can also handle graphics cards in a multi-GPU system. This is extremely useful when you want to put up a PC unit for graphics work or gaming. Another advantage of the power supply is the quiet fan on hydraulic bearings, which adjusts its speed as required and thus ensures adequate cooling. This not only ensures the proper operation of the components, but also the reliability of the PSU.

Guarantee of high efficiency

The high efficiency of the power supply is confirmed by the 80 PLUS® Bronze certificate, which shows that the efficiency of the power supply reaches up to 88%. It also shows that 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.

Reliable protection

The AK-U4-800 power supply is an extremely safe device. Thanks to such protections as: OCP (overcurrent), OVP (over-voltage), UVP (under-voltage), SCP (short circuit), OTP (temperature), OPP (overload). You can be sure that your desktop computer is safe and that its components are properly protected. At the same time, their operation will run without any undesired disturbances or hindrances.  

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.

Variety of connectors

The Ultimate PSU series is equipped with long cables, which simplify the installation especially inside large ATX cases. Furthermore, the included large connector set allows for the supply of power to multiple components and memory. Apart from the previously mentioned PCI-E 6-pin and 6+2-pin connectors, this model comes with 2 MOLEX connectors, 6 SATA connectors, 1 mini-MOLEX and EPS12V 4+4-pin connector each as well as a universal 24-pin motherboard connector
