Description

This Gigabyte brand power supply unit has an 80 PLUS Bronze energy efficiency certificate and a power output of 550W.

The power of 550W is more than sufficient for office programs, web browsing, and light computer games. It will be able to run a basic computer with an integrated graphics card, budget-level processor, small SSD or hard drive. If you plan to upgrade your computer in the future, you should definitely consider a more powerful power supply.

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 received the 80 PLUS Bronze energy efficiency certificate, which guarantees at least 85% efficiency at 50% load. This means that for every 100W of power the power supply draws from the electrical grid, at least 85W is delivered to your computer components, while the remaining 15W is lost as heat.

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

ATX 2.0 standard, which is assigned to this power supply unit, ensures that the unit is equipped only with 6-pin and 8-pin connectors (with respective power of 75W and 150W). For a system with a very powerful graphics card (such as RTX 4070), an ATX 3.* standard unit will be required, and ATX 2.0 will not be sufficient.

The noise level of this power supply is 40-45 dB and it has a Cybenetics Standard noise level certificate.

The power supply unit does not have modular cables; all cables are attached to the power supply unit and are not removable. Despite this, it will work just as well as a power supply unit with modular cables.

The manufacturer of this power supply is Gigabyte. View all Gigabyte power supplies here.
