Power adapter for dual GPU systems

This Vszerda CPU 8-pin to dual PCIe 8-pin (6+2) splitter cable lets a modular PSU feed two graphics cards from a single CPU power connector. The pack contains two black cables each 21 cm long including connectors. It is built with 18 AWG tin-coated copper wire rated for 12 volt delivery. The adapter is intended only for video cards and will not work with motherboards.

Thermals noise and power draw

The 18 AWG conductors handle typical GPU current without excessive voltage drop, keeping connector temperatures within normal limits during everyday gaming or compute workloads. Passive construction means the cables add no fan noise to the system. Power draw at the PSU side equals the combined load of both attached graphics cards, so the supply must be sized accordingly.

Behaviour under sustained load

Under continuous full-load operation the tin-coated copper cores maintain stable 12 volt delivery to both 6+2 pin plugs, provided the PSU and its CPU 8-pin rail can supply the required amperage. The fixed 21 cm length keeps resistance low, reducing heat build-up during extended mining or rendering sessions. Users must verify that total graphics card power stays within the PSU CPU connector rating to avoid overload.

Questions about this item

How do I connect the CPU 8-pin female end to my modular PSU and the dual 8-pin (6+2) male ends to my graphics card?

Plug the CPU 8-pin female connector into the modular PSU's CPU 8-pin port, then attach each 8-pin (6+2) male end to the graphics card's PCIe power sockets; the 2-pin section slides off if the card only needs a 6-pin connection.

What should I check on the 18AWG wires and connectors over time to ensure safe operation?

Inspect the 1007-18AWG tin-coated copper wires and all connectors for discoloration, melted insulation, or loose pins after extended high-load use; replace the cable if any damage appears.

At what point does the 21 cm length limit GPU placement in a large case?

The 21 cm cable (including connectors) restricts how far the graphics card can sit from the PSU's CPU 8-pin port; measure your routing path before installing to confirm reach.
