HeavyDuty 12VHPWR GPU Power Cable, 2 x 8Pin PCIe to 16Pin 12VHPWR Extension Cord, HighCurrent GPU Power Connector for RTX 3090Ti 4070Ti 4080 4090 Graphics Cards

This heavyduty 2x8pin to 16pin 12VHPWR GPU power extension cable is engineered to supply sufficient highcurrent power for highend NVIDIA graphics cards including RTX 3090Ti, 4070Ti, 4080 and 4090. It converts dual standard PCIe 8pin power outputs from your power supply unit into the new 12VHPWR 16pin GPU power interface, eliminating the need for the original small plastic adapter that comes with certain graphics card packages.

Constructed with thick tinned copper inner wires and heatresistant insulating jacket, this cable minimizes voltage drop and heat generation during intense gaming, rendering and longhour fullload operation. The 12VHPWR end features reinforced strainrelief housing to relieve mechanical stress, greatly lowering the risk of connector melting or damage caused by sharp bending or poor cable routing inside computer chassis.

Each 8pin side must connect to separate native PCIe power rails from your PSU for optimal power performance. Latching locking tabs ensure tight insertion to prevent loose connection, intermittent power or unexpected system shutdown. It simplifies internal cable arrangement for ATX, midtower and large gaming cases.

Important reminder: Always use two independent PSU PCIE 8pin power lines, do not daisychain from one single cable. Proper cable routing without sharp angles is required to protect the 12VHPWR connector. This is poweronly cable, no data function. Confirm your power supply can meet GPU total power consumption before installation.
