Black sleeved 16-pin 90-degree GPU power adapter splitting to three 8-pin connectors 15cm length

Vszerda

Vszerda 16 Pin to 3x 8 Pin PCIe 5.0 12VHPWR 600W 90 Degree Type B internal power cable

SKU CH-RJGH-JXK4T

Connects a 16-pin 12VHPWR graphics card to three 8-pin PCIe power connectors with a 90-degree Type B angle, 16 AWG wire rated for 600 W and PCIe 5.0

  • Supports 600W delivery via 16AWG tinned copper wires
  • 90-degree Type B connector reduces strain on GPU port
  • PCIe 5.0 12VHPWR standard for RTX 40 series cards
  • 15 cm sleeved adapter connects three 8-pin PSU cables
  • Requires three free 8-pin PCIe ports on power supply

Compatible GPUs and use-case

This 16-pin to 3x 8-pin adapter targets builders installing RTX 4090, 4080, 4070 Ti or 3090 Ti graphics cards that require the 12VHPWR connector. The 90-degree Type B orientation suits cards whose socket points toward the side panel, reducing strain on the GPU port. It replaces the need for a native 12VHPWR cable when the power supply only offers 8-pin PCIe outputs. The 15 cm sleeved length keeps routing tidy in compact builds.

Interface limits and power delivery

The cable conforms to the PCIe 5.0 12VHPWR standard and is rated for 600 W through 16 AWG tinned-copper conductors with alloy-copper terminals. Stable operation demands three separate 8-pin PCIe ports on the power supply; connecting fewer than three will not work. Builders whose PSU lacks three free 8-pin connectors cannot use this adapter. No other interface or protocol is supported beyond the stated 12VHPWR specification.

Upgrade path and when to choose it

This adapter upgrades a power supply with only 8-pin PCIe outputs to support 12VHPWR graphics cards without replacing the PSU. The jump is worth it when the existing unit has sufficient wattage and three spare 8-pin ports but lacks a native 16-pin cable. It is not for systems that already provide a native 12VHPWR lead, for PSUs with fewer than three 8-pin PCIe connectors, or for GPUs requiring a Type A connector orientation.

Questions about this item

Which orientation should I choose for my RTX 4090, Type A or Type B?

Select Type B when the 16-pin socket on your RTX 4090 or RTX 4080 faces the same direction shown in the product images; Type A is for the opposite orientation.

What does the 600 W rating mean once the cable is installed in my system?

The 16 AWG wires and alloy copper terminals are rated to deliver up to 600 W continuously to an RTX 4090, RTX 4080 or RTX 3090 Ti without overheating.

Does the PCIe 5.0 12VHPWR interface limit the power I can draw?

The 12VHPWR connector follows the PCIe 5.0 specification and supports the full 600 W rating when all three 8-pin plugs are connected to the power supply.
