Converts four ATX 8-pin outputs into a single 12VHPWR 16-pin connector with a 90-degree upward angle for tight spaces, supporting PCIe 5.0 graphics cards up to 600 W
This adapter converts four ATX 8-pin connectors into a single 12VHPWR 16-pin plug that complies with the ATX 3.0 and PCIe 5.0 specifications. It is intended for builders installing RTX 40-series or AMD RDNA 3 graphics cards on power supplies that lack the native connector.
The right-angle design points the cable upward so it fits behind the card even when clearance between the PCB and the side panel is minimal. This geometry reduces strain on the connector and keeps the wire run tidy without forcing sharp bends that can impede airflow.
The PCI-SIG certified H+ layout provides twelve power pins plus four signal pins on the side, enabling the full 600 W rating defined by the new standard. Systems that cannot supply that level from four 8-pin sources will not meet the card's power requirements.
Measured against everything we stock in Internal PSU & Riser Cables, at today’s prices. Recalculated every night.

No published specifications for this item yet.
Plug the four ATX 8-pin connectors fully into the PSU modular ports, then press the 16-pin 12VHPWR end straight into the graphics card socket until the latch clicks; the 90-degree UP bend keeps the cable running parallel to the card instead of protruding outward.
The adapter itself has no moving parts or wear items; inspect the pins for discolouration or bent contacts whenever you rebuild the system and reseat both ends if oxidation appears.
The PCI-SIG 12VHPWR H+ specification caps continuous delivery at 600 W, so any GPU drawing more than that under prolonged load will hit this connector’s ceiling first.
