ARENTI 12VHPWR adapter for RTX 40-series

This ARENTI cable converts three 8-pin PCIe connectors from a modular power supply into a single 12+4-pin 12VHPWR plug. It supports graphics cards such as the RTX 4090, 4080 and 3090 Ti that require the newer connector. The 16 AWG tinned copper conductors are rated for up to 600 W of power delivery.

Replaces the need for an ATX 3.0 power supply

Instead of buying a new ATX 3.0 unit, owners of compatible ASUS, EVGA or Seasonic modular PSUs can use this 70 cm extension. The upgrade makes sense when the existing supply has three spare 8-pin (6+2) ports and meets the card's minimum wattage requirement of 750 W for an RTX 4080 or 850 W for an RTX 4090 or 3090 Ti.

Installation requires three free 8-pin ports

The male-to-male cable plugs directly into the PSU's PCIe/VGA sockets and the graphics card's 12VHPWR socket. Ensure the power supply model appears on the validated compatibility list, which includes EVGA SuperNOVA T2, G2, G3, P2 and P3 units of 850 W and above. Using a PSU not on the list or with fewer than three available ports will prevent a correct connection.
