  • 12+4 pin 12VHPWR connector matches RTX 40 and RDNA 3 cards

12VHPWR 16AWG 90° down-angled extension cable

This 17 cm internal power cable carries a male-to-female 12VHPWR connector built to the ATX 3.0 and PCI-E 5.0 specification. It is designed for builders fitting RTX 40-series or AMD RDNA 3 graphics cards that require the 12+4 pin power interface.

Replaces a straight 12VHPWR lead when clearance is

The 90° down-angled plug routes the cable parallel to the card, freeing space behind the GPU where a straight connector would press against the side panel. The upgrade is worth it when the case window or a rear fan leaves less room than the connector height.

Check GPU power-port orientation

Verify that the card’s 12VHPWR socket faces the motherboard so the down angle points toward the case floor. Confirm the power supply provides a native 12VHPWR header; this cable extends that header and does not adapt from older 8-pin PCIe plugs.

Questions about this item

Will the 90° down-angled 12VHPWR plug clear a 17 cm gap behind my RTX 3090?

The extension measures 17 cm end-to-end and the 90° down angle points the cable toward the motherboard, so it fits in tight rear clearances where a straight plug would hit the side panel.

Do I need to remove the GPU to connect the male 12VHPWR end to the PSU and the female end to the card?

No — route the male end into the PSU 12VHPWR port first, then plug the female end into the graphics-card socket; the short 17 cm length leaves little slack, so seat both connectors fully before securing the GPU.

When should I replace this 16 AWG 12VHPWR extension if I run an RTX 40-series card at 600 W?

Inspect the 12 power pins and 4 signal pins every 6–12 months; replace the cable if any pin shows discoloration, melted plastic or loose retention, as 600 W loads accelerate contact wear.
