Aile Tech 12+4pin to 3×8PIN Extension Cable 340mm 16AWG Black computer power cord

SKU CH-X7MR-N30SB

Extends a 12+4pin 12VHPWR supply connector into three 8-pin PCI-E 5.0 GPU plugs over 340 mm of 16AWG sleeved cable

  • Extends GPU power with a 340mm sleeved 16AWG cable
  • PCI-E 5.0 ready 12+4pin 12VHPWR connector for modern graphics cards
  • Splits one 12VHPWR port into three 8-pin PCIe plugs
  • 16AWG conductors handle up to 16 amps per line
  • 340mm length keeps cable routing tidy inside the case

PCI-E 5.0 12VHPWR Extension Cable

This 12+4pin to 3×8pin sleeved extension cable connects a PCI-E 5.0 graphics card to a power supply using three 8-pin PCIe connectors. It measures 340mm in length and uses 16AWG wire. The black cable is built for RTX 3090 Ti, 4070 and 4080 graphics cards.

Suits builds with a 12VHPWR GPU and an ATX 2.x PSU

Builders whose power supply already provides a native 12+4pin 12VHPWR connector do not need this adapter. It is also not for systems that require a different connector layout or a shorter cable run than 340mm.

12+4pin 12VHPWR to three 8-pin PCIe connectors

The decisive specification is the connector arrangement: one 12+4pin 12VHPWR female end mating with three 8-pin male plugs. Verify that your graphics card uses the 12VHPWR interface and that your power supply offers three available 8-pin PCIe outputs before purchasing.

Questions about this item

How does the 12VHPWR connector affect power delivery to an RTX 4080?

The 12+4pin 12VHPWR connector carries up to 16 A per pin through 16AWG wires, feeding the RTX 4080 from three 8-pin PSU outputs over a 340 mm sleeved run.

What does PCI-E 5.0 mean for this cable's bandwidth or speed?

PCI-E 5.0 here only identifies the 12VHPWR power standard; the cable transmits DC power, not data, so it does not limit or enable any signalling bandwidth.

Will the 340 mm length reach my GPU in a mid-tower case?

At 340 mm the extension adds roughly 34 cm from the PSU's 8-pin ports to the GPU's 12VHPWR socket, which typically spans the distance in standard ATX mid-tower layouts.
