SMUGDESK

SMUGDESK 12VHPWR 12+4Pin PCIe 5.0 to 3X 8Pin GPU Power Splitter Cord

SKU CH-4SX7-JXZ5D

Converts a PCIe 5.0 12VHPWR port to three 8-pin connectors for RTX 3090 Ti, 4080 and 4090 cards

  • Converts PCIe 5.0 12VHPWR to three 8-pin GPU connectors
  • Heavy-gauge copper wiring reduces voltage drop under full load
  • Latching-clip connectors lock securely against vibration and GPU weight
  • Designed for modular PSUs with plug-and-play installation
  • Supports RTX 3090 Ti, RTX 4080 and RTX 4090 high-power graphics cards

Power Splitter Cord

This SMUGDESK power splitter cord converts a modular PSU's native 12VHPWR 12+4 pin port into three standard PCIe 8-pin connectors. It is built for PC builders upgrading to high-power RTX 3090 Ti, RTX 4080 or RTX 4090 graphics cards that demand multiple 8-pin inputs from a single PSU output.

PCIe 5.0 12VHPWR Compatibility

The cable only works when plugged directly into a genuine PCIe 5.0 12VHPWR 12+4 pin modular PSU port. It cannot be used with older 6-pin or 8-pin PSU outputs, nor with CPU EPS12V ports, so the power supply must already provide this specific connector.

Plug-and-Play Installation

Heavy-gauge copper conductors and locking latch clips on every connector give a secure, low-resistance fit that resists vibration and GPU weight. Installers must verify the PSU delivers sufficient total wattage for the graphics card; the cord itself adds no active regulation or voltage conversion.

Questions about this item

What does the 12VHPWR 12+4 pin connector actually deliver to the card?

It converts a single PCIe 5.0 12VHPWR port on a modular PSU into three standard 8-pin PCIe plugs, feeding RTX 3090 Ti, RTX 4080 or RTX 4090 cards with heavy-gauge copper for low voltage drop under full load.

Which PSU port must this cable plug into and what standard does it follow?

It requires a genuine 12VHPWR 12+4 pin modular PSU port built to the PCIe 5.0 specification; it is not compatible with CPU EPS12V headers.

How do the connectors stay secure on a heavy graphics card?

Every 8-pin female and the 12+4 pin male end uses a latching clip that clicks firmly in place, resisting disconnection from GPU weight, chassis vibration or cable tugging.
