Black 180-degree adapter cable with 16-pin 12VHPWR connector and four 8-pin PCIe plugs, Type B orientation

Vszerda

Vszerda 12VHPWR 16 Pin to 4X 8 Pin 600W GPU Power Connector Type B internal power cable

SKU CH-S0YB-2MQER

Converts four 8-pin PCIe connectors into a 12VHPWR 16-pin plug delivering up to 600W with a 180-degree Type B design for RTX 4090, 4080 and 3090Ti cards

  • Delivers up to 600W for high-performance GPUs via four 8-pin PCIe connectors
  • 180-degree adapter angle eases cable routing and reduces strain on the GPU power socket
  • Type B layout with four pins facing outwards matches specific RTX 4090 and 4080 board designs
  • Compatible with ASUS Strix and TUF models plus NVIDIA Founders Edition backplate-side connectors
  • Works with Alphacool Eisblock Aurora water-block backplates on RTX 4090 Strix and TUF cards

12VHPWR 16-pin adapter for RTX 40-series

This internal power cable converts four 8-pin PCIe connectors into a single 12VHPWR 16-pin plug rated for 600 W. It is built for builders fitting an RTX 4090, 4080 or 4070 Ti graphics card into a system with an ATX 3.0 power supply that lacks the native connector.

Type B orientation with 180-degree bend

The 180-degree angle routes the cable parallel to the card, easing routing in tight cases and lowering mechanical stress on the GPU socket. Type B pin-out places the four sense pins facing outwards, matching the connector layout used on ASUS Strix and TUF models as well as NVIDIA Founders Edition backplate-side sockets.

3 mm backplate clearance limit

The adapter only fits when the GPU backplate extends no more than 3 mm beyond the power socket. Cards with thicker backplates or water-blocks that protrude further will prevent the 16-pin plug from seating fully, risking poor contact and overheating.

Questions about this item

Will the 12VHPWR 16-pin connector need periodic reseating to avoid the overheating risk mentioned in the note?

The note warns that an unseated connector causes overheating, so checking the 16-pin is fully inserted during any build maintenance is the only required step.

What stops the 600 W rating from being sustained through the four 8-pin PCIe inputs?

The adapter is rated for 600 W total; the first limit under sustained load is the combined capacity of the four 8-pin sources feeding it.

Does the 180-degree Type B adapter run hotter or draw more power than a straight cable when the GPU runs all day?

The 180-degree bend only changes routing; it adds no resistance or heat, so power draw and temperature stay identical to a straight 12VHPWR cable.
