This is a power supply that complies with ATX 2.0 requirements. The power supply has only 6-pin and 8-pin connectors, which can handle only 75 W and 150 W of power, respectively. Modern graphics cards' high power needs exceed the capabilities of ATX 2.0 connectors. When building a system with a very powerful GPU, such as an RTX 4070, you will need an ATX 3.* standard power supply.
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.
