We offer to purchase a Silverstone power supply unit with a power capacity of 400W, which has received the 80 PLUS (White) energy efficiency certification.
This power supply unit is equipped with a 120 mm fan, which is the industry standard for ensuring quiet operation in average computers. If you want an especially quiet unit, look for one with a fan diameter of 135 mm or 140 mm.
80 PLUS (White) energy efficiency certificate, which this power supply unit has received, guarantees at least 80% efficiency. In other words, for every 100 W of energy the power supply unit gets from the electrical grid, at least 80 W goes to your computer components, while the remaining 20 W is lost as heat.
The color of the block is Melna. The block has flat cables, whose color is Raiba.
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 unit does not have modular cables – all its cables are attached to the unit and are not detachable. Despite the simple design, it will fulfill its functions just as well as a power supply unit with modular cables.
