Description

We offer to purchase a Montech power supply unit with a power capacity of 550W, which has received the 80 PLUS (White) energy efficiency certification.

With 550W power, it will be enough to run Office programs, browse the internet, and play simple computer games. It will be able to run a computer with a budget-level processor, integrated graphics card, small SSD, or HDD disk. If there is a desire to upgrade computer components in the future, it is definitely worth considering a more powerful power supply unit.

The diameter of this power supply unit's fan is 120 mm, which will ensure quiet operation in mid-range computers. For especially quiet power supply unit operation, we recommend selecting a fan with a 135 mm or 140 mm diameter.

The power supply has been awarded the 80 PLUS (White) energy efficiency certificate, which ensures at least 80% efficiency. This indicates that at least 80 W out of 100 W of power received from the mains by the power supply is delivered to the computer components, with the remaining 20 W being lost as heat.

The color of the block is Melna. The block has flat cables, whose color is Melna.

This power supply unit has been assigned the ATX 2.0 standard. This means that the unit is equipped only with 6-pin and 8-pin connectors, providing 75W and 150W power respectively. It's important to note that this unit will be compatible with RTX 4070 and more powerful cards, but you will need to use the 2x8-pin to 16-pin 12VHPWR adapter included with the graphics card. ATX 2.0 power connectors are not designed to handle the high power fluctuations of modern graphics cards; therefore, if you are building a system with a powerful GPU, such as the RTX 4070, we recommend choosing a power supply unit with the ATX 3.* standard and 12VHPWR (PCIe 5.0) connector.

This power supply has no removable cables and all cables are attached to the power supply. It has a simple design, but it works just as well as a power supply with modular cables.
