The black 4-pin ATX12V extension cable from the BitFenix Alchemy series helps to enhance the look of your system. Any unsightly power supply cables can be hidden from view by simply connecting this extension to your existing 4-pin ATX12V connector.The extension can also be used to bridge distances of 45cm when a PSU cable is too short. This can be a common occurrence especially when working with large PC towers. The high-quality sleeving ensures this cable is extremely robust, tear-resistant and durable. This increases the lifespan of the cable and means it can be reused again for future PC builds.Technical details: Length: 450 mmColour: blackConnections: 4-pin ATX12V plug 4-pin ATX12V socket
