Black modular adapter cable with four 8-pin plugs merging into a 90-degree down-angled 16-pin 12VHPWR connector

Vszerda

Vszerda ATX 8Pin 4 Port to 12VHPWR ATX 3.0 PCI-E 5.0 16Pin 90 Degree Down Angled internal power cable

SKU CH-47TE-R33AG

Converts four ATX 8-pin connectors to a 12VHPWR 16-pin plug with a 90-degree down angle for tight GPU clearance

  • Converts four ATX 8-pin ports to a single 12VHPWR connector
  • 90-degree down angle fits tight spaces around the GPU socket
  • PCI-SIG 12VHPWR H+ design delivers up to 600W of power
  • Supports PCIe 5.0 and ATX 3.0 specifications for modern graphics cards
  • Compatible with RTX 40-series and RDNA 3 GPUs requiring the new connector

90-Degree Adapter for Tight Builds

This 12VHPWR adapter converts four ATX 8-pin connectors into a single 16-pin PCIe 5.0 plug. The 90-degree down angle reduces strain in compact cases where clearance behind the graphics card is limited. It targets builders upgrading to modern GPUs without replacing their power supply.

600 W Delivery Across Four Ports

The cable complies with the ATX 3.0 and PCIe 5.0 specifications, supporting up to 600 W through the 12VHPWR H+ interface. Four 8-pin sources provide the necessary headroom for high-end cards such as RTX 40-series and RDNA 3 models. Systems with fewer than four available 8-pin cables cannot use this adapter.

16-Pin 12VHPWR Connector Standard

The decisive specification is the 16-pin 12VHPWR connector with 12 power pins and 4 signal pins. Only graphics cards and power supplies designed for this exact connector will work. Older 8-pin or 12-pin proprietary plugs are not compatible.

Questions about this item

Will the 90 degree down angled 12VHPWR connector fit my RTX 40 series card if the case side panel sits close to the GPU?

Yes, the 90 degree down angle routes the cable parallel to the card so it clears tight side panel gaps that would block a straight plug.

How can I confirm the adapter is delivering the full 600W to my PCIe 5.0 graphics card after installation?

Check GPU-Z or HWInfo under load; the 12VHPWR rail should report 12 V with minimal drop and the four sense pins will show active communication.

Does the package include four separate ATX 8-pin cables or only the adapter block?

Only the modular adapter block is supplied; you must use four existing PSU 8-pin PCIe cables to feed the four input ports.
